Accounting Policies [Abstract]
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES: GENERAL - SJI provides a variety of energy-related products and services primarily through the following wholly-owned subsidiaries: ▪ SJIU is a holding company that owns SJG and ETG and, until its sale in July 2020, owned ELK. • SJG is a regulated natural gas utility which distributes natural gas in the seven southernmost counties of New Jersey. • ETG is a regulated natural gas utility which distributes natural gas in seven counties in northern and central New Jersey. • ELK is a regulated natural gas utility which distributes natural gas in northern Maryland. On July 31, 2020, SJI sold ELK (see "Sale of ELK" below). ▪ SJE acquires and markets electricity to retail end users. ▪ SJRG markets natural gas storage, commodity and transportation assets along with fuel management services on a wholesale basis in the mid-Atlantic, Appalachian and southern states. ▪ SJEX owns oil, gas and mineral rights in the Marcellus Shale region of Pennsylvania. ▪ Marina develops and operates on-site energy-related projects. Marina includes the Catamaran joint venture that was entered into for the purpose of developing, owning and operating renewable energy projects, and supporting SJI's commitment to clean energy initiatives. Catamaran owns Annadale and Bronx Midco, operators of fuel cell projects in New York, in which Marina, through Catamaran, owns 93% and 92%, respectively. Catamaran also owns a solar generation site in Massachusetts, in which Marina, through Catamaran, owns 90%. The remaining ownership percentages are recorded as Noncontrolling Interests in the consolidated financial statements. Previously, Marina also included MTF and ACB, which were sold in February 2020, and solar projects that were sold in 2020 and 2019 as discussed below under Divestitures. The principal wholly-owned subsidiaries of Marina are: • ACLE, BCLE, SCLE and SXLE own landfill gas-to-energy production facilities in Atlantic, Burlington, Salem and Sussex Counties, respectively, located in New Jersey. ACLE ceased operations on September 30, 2021, while BCLE, SCLE and SXLE ceased operations on June 1, 2020. • Marina owns, directly and through wholly-owned subsidiaries, solar energy projects at rooftop generation sites in New Jersey, including projects that were acquired in 2020 and 2021. ▪ SJESP receives commissions on appliance service contracts from a third party. • Midstream invests in infrastructure and other midstream projects, including the PennEast project for which development ceased in September 2021. See Note 3. • SJEI provides energy procurement and cost reduction services. The significant wholly-owned subsidiaries of SJEI include: • AEP, an aggregator, broker and consultant in the retail energy markets that matches end users with suppliers for the procurement of natural gas and electricity. • EnerConnex, an aggregator, broker and consultant in the retail and wholesale energy markets that matches end users with suppliers for the procurement of natural gas and electricity. On August 7, 2020, SJEI acquired the remaining 75% of EnerConnex, of which SJEI previously held a 25% interest. • SJI Renewable Energy Ventures, LLC, which holds our equity interest in REV. • SJI RNG Devco, LLC, which includes our renewable natural gas development rights and costs incurred in order to develop certain dairy farms. BASIS OF PRESENTATION - SJI's consolidated financial statements include the accounts of SJI, its direct and indirect wholly-owned subsidiaries (including SJG) and subsidiaries in which SJI has a controlling interest. All significant intercompany accounts and transactions have been eliminated in consolidation. SJI also reports on a consolidated basis the operations of those entities listed under "Acquisitions" below as of their respective acquisition dates, along with its controlling interest in Catamaran as noted below. In management's opinion, the consolidated financial statements of SJI and SJG reflect all normal recurring adjustments needed to fairly present their respective financial positions, operating results and cash flows at the dates and for the periods presented. Certain prior years' data presented in the financial statements and footnotes have been reclassified to conform to the current year presentation. These reclassifications had no impact on the Company's results of operations, financial position or cash flows. ACQUISITIONS – Additional information about these transactions is included in Note 20. 2021: • Bronx Midco – this entity was formed by Catamaran and a third party and is 99% owned by Catamaran. In June, Bronx Midco purchased a fuel cell project in Bronx, NY, of which Marina, through its ownership in Catamaran, has a 92% ownership interest. • Acquired two solar energy projects, one in New Jersey and the other in Massachusetts. 2020: • Rooftop solar generation sites - SJI, through its wholly-owned subsidiary Marina, acquired three entities owning newly operational solar-generation sites in June and a fourth entity in August. • EnerConnex – In August, SJI, through its wholly-owned subsidiary SJEI, completed its acquisition of the remaining 75% of EnerConnex. Prior to this transaction, SJEI had a 25% interest in EnerConnex; as such, the acquisition of the remaining 75% was accounted for as a business combination achieved in stages. • Catamaran – In August, SJI, through its wholly-owned subsidiary Marina, formed the Catamaran joint venture with a third party partner. On the same date, Catamaran purchased 100% ownership of Annadale, of which Marina has a 93% ownership interest. • REV – In December, SJI, through its wholly-owned subsidiary SJIEE, completed its acquisition of a 35% interest in REV. As part of the transaction, SJI also acquired renewable natural gas development rights in certain dairy farms, previously owned by REV. The 35% interest in REV is accounted for under the equity method of accounting (see Note 3). 2019: • AEP – In August, SJI, through its wholly-owned subsidiary SJEI, completed its acquisition of AEP. DIVESTITURES – • Solar assets – In June 2018, the Company, through its wholly-owned subsidiary, Marina, entered into a series of agreements whereby Marina agreed to sell its then-existing portfolio of solar energy projects (for this section, the "Projects"), along with the assets comprising the Projects. These sales occurred during 2018-2020, including Projects sold during 2020 and 2019 for total consideration of $7.2 million and $24.3 million, respectively. In connection with this transaction, Marina was leasing back from the buyer certain of the Projects that had not yet passed the fifth anniversary of their placed-in-service dates for U.S. federal income tax purposes. The leaseback ran from the date each such Project was acquired by the buyer until the later of the first anniversary of the applicable acquisition date and the fifth anniversary of the applicable placed-in-service date of the Project. As of December 31, 2021, there were no remaining Projects that were being leased back from the buyer. The results of these leased back Projects during the years ended 2021, 2020 and 2019 were not material. The Company recorded pre-tax gains on the sale of these solar projects of $0.8 million and $3.1 million in 2020 and 2019, respectively, in Net Gain on Sales of Assets on the consolidated statements of income, with these gains pertaining to those Projects that were not impaired as discussed under "Impairment of Long-Lived Assets" below. At December 31, 2019, the Company had two projects that are not part of the above transaction but were previously expected to be sold and, as a result, were recorded as Assets Held For Sale on the consolidated balance sheets as of December 31, 2019. During the fourth quarter of 2020, management made the decision not to sell these two projects. As a result, these projects are recorded as held and used in Property, Plant and Equipment on the consolidated balance sheets as of December 31, 2021 and 2020. SJI recorded $5.3 million of depreciation expense during the fourth quarter of 2020 for depreciation not taken during the time the projects were classified as held for sale. Further, the decision not to sell these projects resulted in a triggering event for management to assess these projects for impairment. As a result of the tests performed, no impairments were recorded as the future undiscounted cash flows exceeded the net book value of the projects as of December 31, 2020. • MTF & ACB – In February 2020, the Company sold MTF and ACB for a final sales price of $97.0 million, including working capital and recognized a pre-tax gain in 2020 of $1.1 million, which is recorded in Net Gain on Sales of Assets on the consolidated statements of income. • ELK – In July 2020, the Company sold ELK and, in 2020, received total consideration of approximately $15.6 million and recognized a pre-tax gain of $0.7 million, which is recorded in Net Gain on Sales of Assets on the consolidated statements of income. The working capital settlement finalized in 2021 was not material. IMPAIRMENT OF LONG-LIVED ASSETS - Long-lived assets that are held and used are reviewed for impairment whenever events or changes in circumstances indicate carrying values may not be recoverable. Such reviews are performed in accordance with ASC 360, Property, Plant and Equipment, where an impairment loss is indicated if the total undiscounted cash flows expected from an asset are less than its carrying value. An impairment charge is measured by the difference between an asset's carrying amount and fair value, with the difference recorded within Impairment Charges on the consolidated statements of income. Fair values can be determined based on agreements to sell assets as well as by a variety of valuation methods, including third-party appraisals, sales prices of similar assets, and present value techniques. We assessed the long-lived assets of SJI and SJG as of December 31, 2021 and 2020 to determine whether a potential impairment was indicated, including assessing the impact of the COVID-19 pandemic. There were no indicators noted through these assessments that an impairment had occurred. In 2019, total impairment charges of $10.8 million (pre-tax) were recorded, $2.4 million of which were related to the expected purchase price of two of the unsold solar sites discussed in "Divestitures" being less than their carrying value. The other $8.4 million were impairments of goodwill and identifiable intangible assets, which were the result of the purchase price for MTF and ACB discussed in "Divestitures" being less than its carrying value. These impairment charges were recorded within Impairment Charges on the consolidated statements of income in 2019 and were included within the Renewables segment. For considerations related to impairments of goodwill and other intangible assets under FASB ASC 350, Intangibles - Goodwill and Other, see Note 21. EQUITY INVESTMENTS - Marketable equity securities that are purchased as long-term investments are classified as Available-for-Sale Securities and carried at their fair value on the consolidated balance sheets. Any unrealized gains or losses are included in AOCL. SJI, through wholly-owned subsidiaries, holds significant variable interests in several companies but is not the primary beneficiary. Consequently, these investments are accounted for under the equity method. SJI includes the operations of these affiliated companies on a pre-tax basis in the statements of consolidated income under Equity in (Losses) Earnings of Affiliated Companies. In the event that losses and/or distributions from these equity method investments exceed the carrying value, and the Company is obligated to provide additional financial support, the excess will be recorded as either a current or non-current liability on the consolidated balance sheets. If we have provided any additional financial support to the investee, such as loans or advances, our share of losses that exceed the carrying amount of our investment are recorded against that amount of financial support. An impairment loss is recorded when there is clear evidence that a decline in value is other than temporary. See discussion of our equity method investments, including PennEast and Energenic and their related impairment losses, in Note 3. NONCONTROLLING INTERESTS - Interests held by third parties in consolidated majority-owned subsidiaries are presented as noncontrolling interests, which represents the noncontrolling stockholders’ interests in the underlying net assets of the Company’s consolidated majority-owned subsidiaries. As of December 31, 2021, SJI's noncontrolling interests balances are solely related to the Catamaran projects (see Note 20). ESTIMATES AND ASSUMPTIONS - The consolidated financial statements were prepared to conform with GAAP. Management makes estimates and assumptions that affect the amounts reported in the consolidated financial statements and related disclosures. Therefore, actual results could differ from those estimates. Significant estimates include amounts related to regulatory accounting, energy derivatives, environmental remediation costs, legal contingencies, pension and other postretirement benefit costs, revenue recognition, goodwill, evaluation of equity method investments for other-than-temporary impairment, income taxes and allowance for credit losses. Estimates may be subject to future uncertainties, including the continued evolution of the COVID-19 pandemic and its impact on our operations and economic conditions, which could affect the fair value of the ETG reporting unit and its goodwill balance (see Note 21), as well as the allowance for credit losses and the total impact and potential recovery of incremental costs associated with COVID-19 (see Notes 7 and 11, respectively). REGULATION - The Utilities are subject to the rules and regulations of the BPU. See Note 10 for a discussion of the Utilities' rate structure and regulatory actions. The Utilities maintain their accounts according to the BPU's prescribed Uniform System of Accounts. The Utilities follow the accounting for regulated enterprises prescribed by ASC 980, Regulated Operations , which allows for the deferral of certain costs (regulatory assets) and creation of certain obligations (regulatory liabilities) when it is probable that such items will be recovered from or refunded to customers in future periods. See Note 11 for more information related to regulatory assets and liabilities. OPERATING REVENUES - Gas and electric revenues are recognized in the period the commodity is delivered to customers. For retail customers (including customers of SJG) that are not billed at the end of the month, we record an estimate to recognize unbilled revenues for gas and electricity delivered from the date of the last meter reading to the end of the month. The Utilities also have revenues that arise from alternative revenue programs, which are discussed in Note 19. For ETG and SJG, unrealized gains and losses on energy-related derivative instruments are recorded in Regulatory Assets or Regulatory Liabilities on the consolidated balance sheets of SJI and SJG (see Note 16) until they become realized, in which case they are recognized in operating revenues. SJRG's gas revenues are recognized in the period the commodity is delivered, and operating revenues for SJRG include realized and unrealized gains and losses on energy-related derivative instruments. See further discussion under "Derivative Instruments." SJRG presents revenues and expenses related to its energy trading activities on a net basis in operating revenues. This net presentation has no effect on operating income or net income. The Company recognizes revenue for commissions received related to SJESP appliance service contracts, along with commissions received related to AEP and EnerConnex energy procurement service contracts, on a monthly basis as the commissions are earned. Marina recognizes revenue for renewable energy projects when output is generated and delivered to the customer, and when renewable energy credits have been transferred to the third party at an agreed upon price. See further information in Note 19. We considered the impact the COVID-19 pandemic has had on operating revenues, noting that SJI and SJG have not seen a significant reduction in revenues as a result of the pandemic. This is due to the delivery of gas and electricity being considered an essential service, with delivery to customers continuing in a timely manner with no delays or operational shutdowns taking place to date. To the extent that the pandemic does impact our ability to deliver in the future, operating revenues could be impacted. Currently, the impact of the pandemic to the collectability of our accounts receivable continues to be monitored, but such receivables have traditionally been included in rate recovery (see Note 11). ACCOUNTS RECEIVABLE AND ALLOWANCE FOR CREDIT LOSSES - Accounts receivable are carried at the amount owed by customers. Accounts receivable are recorded gross on the consolidated balance sheets with an allowance for credit losses shown as a separate line item titled Provision for Uncollectibles. Beginning January 1, 2020, an allowance for credit losses was established in accordance with ASC 326, Financial Instruments - Credit Losses , meaning accounts receivables and unbilled revenues are carried at net realizable value based on the allowance for credit loss model, which is based on management's best estimate of expected credit losses to reduce accounts receivable for amounts estimated to be uncollectible. These estimates are based on such data as our accounts receivable aging, collection experience, current and forecasted economic conditions and an assessment of the collectibility of specific accounts. See Note 7. NATURAL GAS IN STORAGE – Natural Gas in Storage is reflected at average cost on the consolidated balance sheets, and represents natural gas that will be utilized in the ordinary course of business. ARO - The amounts included under ARO are primarily related to the legal obligations of SJI and SJG to cut and cap gas distribution pipelines when taking those pipelines out of service in future years. These liabilities are generally recognized upon the acquisition or construction of the asset, or when management has sufficient information to make an estimate of the obligation. The related asset retirement cost is capitalized concurrently by increasing the carrying amount of the related asset by the same amount as the liability and is depreciated over the remaining life of the related asset. Changes in the liability are recorded for the passage of time (accretion) or for revisions to cash flows originally estimated to settle the ARO. ARO activity was as follows (in thousands): SJI (includes SJG and all other consolidated subsidiaries): 2021 2020 AROs as of January 1, $ 202,092 $ 263,950 Accretion 8,875 8,185 Additions 6,605 6,574 Settlements (8,736) (9,564) Revisions in Estimated Cash Flows (A) 20,194 (67,053) AROs as of December 31, $ 229,030 $ 202,092 SJG: 2021 2020 AROs as of January 1, $ 89,252 $ 96,509 Accretion 3,776 4,121 Additions 3,017 3,729 Settlements (2,221) (2,579) Revisions in Estimated Cash Flows (A) 9,547 (12,528) AROs as of December 31, $ 103,371 $ 89,252 (A) The revisions in estimated cash flows for SJI and SJG for the year ended December 31, 2021 reflect changes in inflation, and for the year ended December 31, 2020 reflect decreases in the estimated retirement costs primarily as a result of changes in contractor costs to settle the ARO liability, along with a decrease to the discount rate. PROPERTY, PLANT AND EQUIPMENT - For regulatory purposes, utility plant is stated at original cost, which may be different than costs if the assets were acquired from an unregulated entity. Nonutility property, plant and equipment is stated at cost. The cost of adding, replacing and renewing property is charged to the appropriate plant account. Utility Plant balances and Nonutility Property and Equipment as of December 31, 2021 and 2020 were comprised of the following (in thousands): SJI (includes SJG and all other consolidated subsidiaries): SJG 2021 2020 2021 2020 Utility Plant Production Plant $ 241 $ 1,334 $ 25 $ 25 Storage Plant 82,313 90,294 62,140 61,971 Transmission Plant 345,716 338,981 322,051 311,272 Distribution Plant 4,703,918 4,330,797 2,923,016 2,705,893 General Plant 430,940 428,737 264,194 265,185 Other Plant 1,955 1,955 1,855 1,855 Utility Plant In Service 5,565,083 5,192,098 3,573,281 3,346,201 Construction Work In Progress 117,722 73,563 40,079 41,630 Total Utility Plant $ 5,682,805 $ 5,265,661 $ 3,613,360 $ 3,387,831 Accumulated Depreciation (975,619) (914,122) (656,829) (606,925) Net Utility Plant $ 4,707,186 $ 4,351,539 $ 2,956,531 $ 2,780,906 Nonutility Property and Equipment Solar Assets $ 61,478 $ 40,380 N/A N/A Fuel Cell Assets 80,550 80,546 N/A N/A Other Assets 24,711 26,838 N/A N/A Construction Work In Progress (A) 73,764 — Total Nonutility Property and Equipment $ 240,503 $ 147,764 Accumulated Depreciation (35,367) (35,069) Net Nonutility Property and Equipment $ 205,136 $ 112,695 (A) Represents costs incurred for ongoing construction of fuel cells, solar energy projects, and renewable natural gas facilities and equipment at dairy farms. DEPRECIATION - We depreciate utility plant on a straight-line basis over the estimated remaining lives of the various property classes. These estimates are periodically reviewed and adjusted as required after BPU approval. The composite annual rate for all SJG depreciable utility property was approximately 2.4% in 2021, 2.5% in 2020, and 2.2% in 2019. The composite rate for all ETG depreciable utility property was approximately 2.5% in 2021, 2.3% in 2020, and 2.4% in 2019. The actual composite rate may differ from the approved rate as the asset mix changes over time. Except for retirements outside of the normal course of business, accumulated depreciation is charged with the cost of depreciable utility property retired, less salvage. All solar and fuel cell assets are included in Nonutility Property, Plant & Equipment on the consolidated balance sheets. Depreciation for solar assets is computed on a straight-line basis over the estimated useful lives of the assets, which range from 20 to 35 years depending on the length of underlying project contracts. All other nonutility property depreciation is computed on a straight-line basis over the estimated useful lives of the property, ranging up to 15 years. Gain or loss on the disposition of nonutility property is recognized in operating income. CAPITALIZED SOFTWARE COSTS - For implementation costs incurred in a cloud computing arrangement that is a service contract, SJI and SJG capitalize certain costs incurred during the application-development and post-implementation-operation stages (provided the costs result in enhanced functionality to the hosted solution) in accordance with ASC 350-40. These costs are amortized over the life of the cloud computing arrangement. All other costs that do not meet the capitalization criteria per ASC 350-40 are expensed as incurred. LEASES - SJI, directly and through certain of its subsidiaries, including SJG, is a lessee of real estate (land and building), fleet vehicles, and office equipment. The Company evaluates its contracts at the lease inception date for the purpose of determining whether the contract is, or contains, a lease on the basis of whether or not the contract grants the Company the use of a specifically identified asset for a period of time, as well as whether the contract grants the Company both the right to direct the use of that asset and receive substantially all of the economic benefits from the use of the asset. We measure the right-of-use asset and lease liability at the present value of future lease payments excluding variable payments based on usage or performance. The majority of our leases are comprised of fixed lease payments, with a portion of the Company’s real estate, fleet vehicles, and office equipment leases including lease payments tied to levels of production, maintenance and property taxes, which may be subject to variability. Variable lease costs not included in the measurement of the lease are presented and disclosed as variable lease cost. We also evaluate contracts in which we are the owner of an underlying asset in the same manner as if it was a lease, to determine if we should be considered the lessor of that asset. The discount rate used to classify and measure a lease where SJI is a lessee is the rate implicit in the lease unless that rate cannot be readily determinable. In that case, the Company uses its incremental borrowing rate which is a lease-specific secured borrowing rate that factors in SJI’s credit standing and the lease term. SJI uses its incremental borrowing rate as the rate implicit in its leases is not readily determinable, except for the related party lease with SJG as discussed in Note 9. When measuring a lease, we include options to extend a lease in the lease term when it is reasonably certain that the option will be exercised and exclude all options to terminate the lease when it is reasonably certain that the option will not be exercised. When determining if a renewal option is reasonably certain of being exercised, the Company considers several economic factors, including the significance of leasehold improvements incurred on the property, whether the asset is difficult to replace, underlying contractual obligations, or specific characteristics unique to that particular lease that would make it reasonably certain that we would exercise such option. The renewal options in the leases generally allow the Company to extend the lease for an additional period of between 1 and 5 years, with the exception of a lease agreement between SJI and SJG (see Note 9). Our lease agreements generally do not include restrictions, financial covenants or residual value guarantees. In addition, other than the intercompany lease between SJI and SJG (see Note 9), the Company has not entered into any related party leases. ASC 842 includes certain practical expedients for arrangements where we are a lessee. We have elected, for all asset classes, the practical expedient to not separate lease components (e.g., costs related to renting the property) from their related non-lease components (e.g., common area maintenance costs), resulting in accounting for them as a single lease component. We have similarly elected, for all asset classes, the balance sheet recognition exemption for all leases with a term of 12 months or less. ASC 842 defines a short-term lease as any lease with a term of 12 months or less which does not include a purchase option that is reasonably certain of being exercised. ASC 842 includes a balance sheet recognition exemption for short-term leases, which the Company has elected for all asset classes. The Company recognizes lease cost for short-term leases on a straight-line basis over the lease term. DEBT ISSUANCE COSTS & DEBT DISCOUNTS - Debt issuance costs and debt discounts are capitalized and amortized as interest expense on a basis which approximates the effective interest method over the term of the related debt, and are presented as a direct deduction from the carrying amount of the related debt. See Note 14 for total unamortized debt issuance costs and debt discounts that are recorded as a reduction to long-term debt on the consolidated balance sheets of SJI and SJG. AFUDC & CAPITALIZED INTEREST - SJI and SJG record AFUDC, which represents the estimated debt and equity costs of capital funds that are necessary to finance the construction of new facilities, at the rate of return on the rate base utilized by the BPU to set rates in the Utilities' last base rate proceedings, and amounts are included in Utility Plant on the consolidated balance sheets. These capitalized interest amounts are included in all plant categories, including Construction Work In Progress, in the Utility Plant table above, based on the nature of the underlying projects that qualified for AFUDC and each project's in-service status. For SJG's accelerated infrastructure programs and ETG's infrastructure investment programs, SJG and ETG record AFUDC at a rate prescribed by the programs which are discussed in Note 10. While cash is not realized currently, AFUDC increases the regulated revenue requirement and is included in rate base and recovered over the service life of the asset through a higher rate base and higher depreciation. Interest charges are presented net of AFUDC and capitalized interest on the statements of consolidated income. The amount of AFUDC and interest capitalized by SJI (including SJG) for the years ended December 31, 2021, 2020 and 2019 was $5.7 million, $7.1 million and $6.0 million, respectively. The amount of AFUDC and interest capitalized by SJG for the years ended December 31, 2021, 2020 and 2019 was $2.9 million, $5.6 million and $4.5 million, respectively. DERIVATIVE INSTRUMENTS - SJI accounts for derivative instruments in accordance with ASC 815, Derivatives and Hedging . We record all derivatives, whether designated in hedging relationships or not, on the consolidated balance sheets at fair value unless the derivative contracts qualify for the normal purchase and sale exemption. In general, if the derivative is designated as a fair value hedge, we recognize the changes in the fair value of the derivative and of the hedged item attributable to the hedged risk in earnings. SJI and SJG have no fair value or cash flow hedges. We formally document all relationships between hedging instruments and hedged items, as well as our risk management objectives, strategies for undertaking various hedge transactions and our methods for assessing and testing correlation and hedge ineffectiveness. All hedging instruments are linked to the hedged asset, liability, firm commitment or forecasted transaction. Due to the application of regulatory accounting principles under ASC 980, gains and losses on derivatives related to SJG's and ETG's gas purchases are recorded through the BGSS clause. Initially and on an ongoing basis, we assess whether derivatives designated as hedges are highly effective in offsetting changes in cash flows or fair values of the hedged items. We discontinue hedge accounting prospectively if we decide to discontinue the hedging relationship; determine that the anticipated transaction is no longer likely to occur; or determine that a derivative is no longer highly effective as a hedge. In the event that hedge accounting is discontinued, we will continue to carry the derivative on the balance sheet at its current fair value and recognize subsequent changes in fair value in current period earnings. Unrealized gains and losses on the discontinued hedges that were previously included in AOCL will be reclassified into earnings when the forecasted transaction occurs, or when it is probable that it will not occur. Hedge accounting has been discontinued for all remaining derivatives that were designated as hedging instruments. As a result, unrealized gains and losses on these derivatives, that were previously recorded in AOCL on the consolidated balance sheets, are being recorded into earnings over the remaining lives of the derivative contracts. TREASURY STOCK – SJI uses the par value method of accounting for treasury stock. As of December 31, 2021 and 2020, SJI held 229,978 and 256,372 shares of treasury stock, respectively. These shares are related to deferred compensation arrangements where the amounts earned are held in the stock of SJI. INCOME TAXES - Deferred income taxes are provided for all significant temporary differences between the book and taxable bases of assets and liabilities in accordance with ASC 740, Income Taxes (see Note 4). Certain deferred income taxes are recorded with offsetting regulatory assets or liabilities by the Company to recognize that income taxes will be recovered or refunded through future rates. A valuation allowance is recorded when it is more likely than not that any of SJI's or SJG's deferred tax assets will not be realized (see Note 4). The U.S. federal government provides businesses with an ITC under Section 48 of the Internal Revenue Code, available to the owner of solar and fuel cell systems that are purchased and placed into service. The Company recognizes ITC on eligible assets in the year in which the project commences commercial operations. Among other requirements, such credits require projects to have commenced construc

STOCK-BASED COMPENSATION PLAN

STOCK-BASED COMPENSATION PLAN	12 Months Ended
	Dec. 31, 2021
Share-based Payment Arrangement [Abstract]
STOCK-BASED COMPENSATION PLAN	STOCK-BASED COMPENSATION PLAN: Under SJI's Omnibus Equity Compensation Plan (Plan), shares, stock appreciation rights, and options may be issued to SJI’s officers (Officers), non-employee directors (Directors) and other key employees. Grants to Officers and other key employees - SJI grants time-based shares of restricted stock, one-third of which vest annually over a three-year period and which are limited to a 100% payout. The vesting and payout of time-based shares of restricted stock is solely contingent upon the service requirement being met in years one two three Performance-based grants containing market-based performance targets use SJI's TSR relative to a peer group to measure performance. As these TSR-related performance-based grants are contingent upon market and service conditions, SJI is required to measure and recognize stock-based compensation expense based on the fair value at the date of grant on a straight-line basis over the requisite three-year period of each award. In addition, SJI identifies specific forfeitures of share-based awards, and compensation expense is adjusted accordingly over the requisite service period. Compensation expense is not adjusted based on the actual achievement of the market-based goals. The fair value of TSR-related performance-based restricted stock awards on the date of grant is estimated using a Monte Carlo simulation model. Performance-based grants containing earnings-based performance targets use pre-defined CEGR goals for SJI to measure performance. As CEGR-based grants are contingent upon performance and service conditions, SJI is required to measure and recognize stock-based compensation expense based on the fair value at the date of grant over the requisite three-year period of each award. The fair value is measured as the market price at the date of grant. The initial accruals of compensation expense are based on the estimated number of shares expected to vest, assuming the requisite service is rendered and probable outcome of the performance condition is achieved. That estimate is revised if subsequent information indicates that the actual number of shares is likely to differ from previous estimates. Compensation expense is ultimately adjusted based on the actual achievement of service and performance targets. Grants to Directors - SJI granted 54,419, 38,456 and 30,961 restricted shares to Directors in 2021, 2020 and 2019, respectively. Shares issued to Directors vest after twelve months and contain no performance conditions. As a result, 100% of the shares granted generally vest. The following table summarizes the nonvested restricted stock awards outstanding at December 31, 2021, and the assumptions used to estimate the fair value of the awards: Grants Shares Outstanding Fair Value Per Share Expected Volatility Risk-Free Interest Rate Officers & Key Employees - 2019 - TSR 32,292 $ 32.88 23.2 % 2.40 % 2019 - CEGR, Time 69,265 31.38 N/A N/A 2020 - TSR 38,813 $ 25.51 34.8 % 0.21 % 2020 - CEGR, Time 123,487 $ 25.19 N/A N/A 2021- TSR 42,716 $ 28.11 39.9 % 0.27 % 2021 - CEGR, Time 185,902 $ 25.33 N/A N/A Directors - 2021 54,419 $ 24.75 N/A N/A Expected volatility is based on the actual volatility of SJI’s share price over the preceding three-year period as of the valuation date. The risk-free interest rate is based on the zero-coupon U.S. Treasury Bond, with a term equal to the three-year term of the Officers' and other key employees' restricted shares. As notional dividend equivalents are credited to the holders during the three-year service period, no reduction to the fair value of the award is required. As the Directors’ restricted stock awards contain no performance conditions and dividends are paid or credited to the holder during the twelve month service period, the fair value of these awards is equal to the market value of the shares on the date of grant. The following table summarizes the total stock-based compensation cost to SJI for the years ended December 31 (in thousands): 2021 2020 2019 Officers & Key Employees $ 5,069 $ 4,590 $ 4,371 Directors 897 1,207 838 Total Cost 5,966 5,797 5,209 Capitalized (440) (46) (275) Net Expense $ 5,526 $ 5,751 $ 4,934 The table above does not reflect the reversal of approximately $1.3 million in 2020 of previously recorded costs associated with TSR and CEGR-based grants for which performance goals were not met. As of December 31, 2021, there was $6.0 million of total unrecognized compensation cost related to nonvested stock-based compensation awards granted under the Plan. That cost is expected to be recognized over a weighted average period of 1.6 years. The following table summarizes information regarding restricted stock award activity for SJI during 2021, excluding accrued dividend equivalents: Officers & Other Key Employees Directors Weighted Average Fair Value Nonvested Shares Outstanding, January 1, 2021 449,786 38,456 $ 28.88 Granted 243,540 54,419 $ 25.66 Vested (172,019) (38,456) $ 30.37 Cancelled/Forfeited (28,832) — $ 25.71 Nonvested Shares Outstanding, December 31, 2021 492,475 54,419 $ 26.72 SJI has a policy of issuing new shares to satisfy its obligations under the Plan; therefore, there are no cash payment requirements resulting from the normal operation of the Plan. However, a change in control could result in such shares becoming non-forfeitable or immediately payable in cash. At the discretion of the Officers, Directors and other key employees, the receipt of vested shares can be deferred until future periods. These deferred shares are included in Treasury Stock on the consolidated balance sheets. During the years ended December 31, 2021, 2020 and 2019, SJI issued 146,597, 78,149 and 125,288 shares to its Officers and other key employees at a market value of $3.6 million, $2.2 million and $3.7 million. These issued shares include shares deferred for payout in prior years. SJG - Officers and other key employees of SJG participate in the Plan. During the years ended December 31, 2021, 2020 and 2019, SJG officers and other key employees were granted 23,010, 7,902 and 6,095 shares, respectively, of SJI restricted stock, which had an immaterial impact to SJG's financial statements for all years.

Business Combinations [Abstract]
AFFILIATIONS, DISCONTINUED OPERATIONS AND RELATED-PARTY TRANSACTIONS	AFFILIATIONS, DISCONTINUED OPERATIONS AND RELATED-PARTY TRANSACTIONS: AFFILIATIONS — The following affiliated entities are accounted for under the equity method: PennEast - Midstream has a 20% investment in PennEast. The following events have occurred with respect to PennEast: • On September 10, 2019, the U.S. Court of Appeals for the Third Circuit ruled that PennEast does not have eminent domain authority over NJ state-owned lands. A Petition for Rehearing En Banc was denied by the U.S. Court of Appeals for the Third Circuit on November 5, 2019. • On October 8, 2019, the NJDEP denied and closed PennEast’s application for several permits without prejudice, citing the Third Circuit decision. On October 11, 2019, PennEast submitted a letter to the NJDEP objecting to its position that the application is administratively incomplete. PennEast's objections were rejected by the NJDEP on November 18, 2019. • In December 2019, PennEast asked the FERC for a two-year extension to construct the pipeline. • On January 30, 2020, the FERC voted to approve PennEast’s petition for a declaratory order and expedited action requesting that FERC issue an order interpreting the Natural Gas Act’s eminent domain authority. On the same day, PennEast filed an amendment with the FERC to construct PennEast in two phases. Phase one consisted of construction of a pipeline in Pennsylvania from the eastern Marcellus Shale region in Luzerne County that would terminate in Northampton County. Phase two included construction of the remaining original certificated route in Pennsylvania and New Jersey. Construction was expected to begin following approval by the FERC of the phased approach and receipt of any remaining governmental and regulatory permits. • On February 18, 2020, PennEast filed a Petition for a Writ of Certiorari with the Supreme Court of the United States ("petition") to review the September 10, 2019 Third Circuit decision. • On February 20, 2020, FERC granted PennEast’s request for a two-year extension to complete the construction of the pipeline. • On April 14, 2020, the U.S. Supreme Court ordered the State of New Jersey to respond to PennEast's petition. The court directed NJ respondents, including state agencies and the NJ Conservation Foundation, to answer the petition by PennEast. The state responded on June 2, 2020. • On June 29, 2020, the U.S. Supreme Court invited the U.S. Solicitor General to file a brief expressing the views of the United States. • On December 9, 2020, the Solicitor General filed a brief supporting PennEast's petition for a Writ of Certiorari. • On December 23, 2020, the NJ Attorney General filed a brief with the Supreme Court in response to the brief of the Solicitor General. • On February 3, 2021, the Supreme Court granted PennEast's petition for a Writ of Certiorari. • On June 29, 2021, the Supreme Court ruled that PennEast can sue New Jersey to secure key land-use rights for the project. • On September 27, 2021, the PennEast partners announced that further development of the project is no longer supported. • On December 16, 2021, the FERC, recognizing the cancellation of the project, vacated its prior approval of the project. Despite the favorable outcomes from the Supreme Court, PennEast continued to experience regulatory and legal challenges resulting in continued delays preventing the commencement of construction and commercial operation of the project. As a result, the Company evaluated its investment in PennEast for an other-than-temporary impairment as of June 30, 2021. Our impairment assessment used a discounted cash flow income approach, including consideration of the severity and duration of any decline in fair value of our investment in the project. Our significant estimates and assumptions included development options and the likelihoods of success of such options, potential regulatory and legal outcomes, construction costs, timing of in-service dates, revenues (including forecasted volumes and rates), and discount rates. The Company estimated the fair value of its investment in PennEast using probability weighted scenarios assigned to discounted future cash flows. Based upon this analysis, in the second quarter of 2021, the Company recognized an other-than-temporary impairment charge of $87.4 million, which is recorded in Equity in (Losses) Earnings from Affiliates in the consolidated statements of income for the year ended December 31, 2021 and reduced its investment in PennEast. As of December 31, 2021, the Company’s investment in PennEast totaled $8.2 million as compared to $91.3 million as of December 31, 2020. The impairment did not result in a tax benefit during the year ended December 31, 2021, as a valuation allowance had been established for the federal deferred tax asset related to the capital loss (see Note 4). In September 2021, the PennEast partners, following extensive evaluation and discussion, determined that further development of the project was no longer supported, and thus all further development of the project has ceased. Given that construction of the pipeline will not continue, the Company re-evaluated its investment for an additional other-than temporary impairment. It was determined that no additional impairment was needed as the current value of the investment represented the best estimate of the salvage value of the remaining assets of the project. It is possible that future developments could impact the fair value and could result in the recognition of additional impairment charges. Summarized financial information for the years ended December 31 for PennEast, as derived from their statements of income for 2021, 2020 and 2019, is below (in thousands): 2021 2020 2019 Revenues $ — $ — $ — Gross Profit $ — $ — $ — (Loss) Income from Continuing Operations $ (416,073) $ 34,663 $ 32,291 Net (Loss) Income $ (416,073) $ 34,663 $ 32,291 Net (Loss) Income Attributable to South Jersey Industries, Inc. $ (83,215) $ 6,933 $ 6,458 Summarized financial information as of December 31 for PennEast as derived from their balance sheets for 2021 and 2020, is below (in thousands): 2021 2020 Current Assets $ 1,216 $ 3,079 Noncurrent Assets $ 45,000 $ 456,205 Current Liabilities $ 479 $ 2,789 Noncurrent Liabilities $ 500 $ — Energenic - Marina and a joint venture partner formed Energenic, in which Marina has a 50% equity interest. Energenic developed and operated on-site, self-contained, energy-related projects. Energenic currently does not have any projects that are operational; however, it owns cogeneration, long-lived assets for which Energenic has been pursuing project development opportunities. Marina has notes and related interest receivable related to Energenic; such notes are secured by the cogeneration assets. Energenic reviewed these cogeneration assets for impairment as of December 31, 2021, as it was determined that future development of a project to utilize these assets is no longer probable, and thus the net book value of these assets may exceed their fair market value. The impairment assessment was performed in accordance with ASC 360, Property, Plant and Equipment, and included consideration of development opportunities for the assets as well as receiving a third-party price quote for similar assets. As a result of the impairment test performed, Energenic recorded an impairment charge of $12.7 million, of which Marina recorded its 50% equity interest, or $6.4 million, which was recorded in Equity in (Losses) Earnings of Affiliated Companies on the consolidated statements of income. This loss reduced the Notes Receivable – Affiliate balance on the consolidated balance sheets as our investment in the Energenic affiliate had been reduced to zero as a result of previous losses. As a result of the impairment charge taken by Energenic, Marina evaluated the realizability of its remaining recorded interests in Energenic, which include notes receivable and accrued interest, and determined that these interests were no longer realizable above the amount of Marina's share in the fair market value of Energenic's cogeneration assets. As a result, we recognized an other-than-temporary impairment charge of $9.1 million. Of this amount, $6.4 million was recorded in Other Income and Expense related to the write off of interest accrued on the notes receivable (which decreased Accounts Receivable on the consolidated balance sheets), and $2.7 million was recorded in Equity in (Losses) Earnings of Affiliated Companies (which decreased Notes Receivable – Affiliate on the consolidated balance sheets). Summarized financial information for the years ended December 31 for Energenic, as derived from their statements of income for 2021, 2020 and 2019, is below (in thousands): 2021 2020 2019 Revenues $ 143 $ 144 $ 144 Gross Profit $ 61 $ 64 $ 65 Losses from Continuing Operations $ (16,628) $ (3,797) $ (3,795) Net Losses $ (16,628) $ (3,797) $ (3,795) Net Losses Attributable to South Jersey Industries, Inc. $ (8,314) $ (1,898) $ (1,898) Summarized financial information as of December 31 for Energenic as derived from their balance sheets for 2021 and 2020, is below (in thousands): 2021 2020 Current Assets $ 11,181 $ 10,284 Noncurrent Assets $ 8,764 $ 24,296 Current Liabilities $ 17,456 $ 15,319 Noncurrent Liabilities $ 29,378 $ 29,522 Millennium - SJI and a joint venture partner formed Millennium, in which SJI has a 50% equity interest. Millennium reads utility customers’ meters on a monthly basis for a fee. Potato Creek - SJI and a joint venture partner formed Potato Creek, in which SJEX has a 30% equity interest. Potato Creek owns and manages the oil, gas and mineral rights of certain real estate in Pennsylvania. EnergyMark - SJE has a 33% investment in EnergyMark, an entity that acquires and markets natural gas to retail end users . For the years ended December 31, 2021, 2020 and 2019, SJRG had net sales to EnergyMark of $25.6 million, $13.7 million and $27.8 million, respectively. REV - SJI Renewable Energy Ventures, LLC has a 35% equity interest in REV, an LNG distributor and developer of LNG and RNG assets and projects. Summarized financial information for the years ended December 31 for all affiliates, as derived from their statements of income for 2021, 2020 and 2019, is below (in thousands): 2021 2020 2019 Revenues $ 136,819 $ 77,266 $ 94,570 Gross Profit $ 30,919 $ 16,278 $ 14,930 (Loss) Income from Continuing Operations $ (424,006) $ 36,906 $ 32,825 Net (Loss) Income $ (424,006) $ 36,906 $ 32,825 Net (Loss) Income Attributable to South Jersey Industries, Inc. $ (90,961) $ 8,294 $ 7,314 Summarized financial information as of December 31 for all affiliates as derived from their balance sheets for 2021 and 2020, is below (in thousands): 2021 2020 Current Assets $ 67,160 $ 38,286 Noncurrent Assets $ 113,685 $ 505,846 Current Liabilities $ 40,214 $ 30,586 Noncurrent Liabilities $ 93,285 $ 49,737 AFFILIATE TRANSACTIONS - The Company made net investments in and net advances to certain of the above unconsolidated affil iat es of $60.6 million, $28.9 million and $8.3 million in 2021, 2020 and 2019, respectively. As of December 31, 2021 and 2020, the outstanding balance of Notes Receivable – Affiliates was $69.9 million and $33.9 million, respectively. These Notes Receivable-Affiliates are comprised of: • As of December 31, 2021 and 2020, $62.6 million and $19.3 million, respectively, of the notes are related to REV which accrue interest at variable rates. • As of December 31, 2021 and 2020, $2.0 million and $12.1 million, respectively, of notes are related to Energenic, after the impairments discussed above. Such notes are secured by Energenic's cogeneration assets for energy service projects, accrue interest at 7.5%, which is no longer being recognized by Marina as a result of the impairments discussed above, and are to be repaid through 2025, although the Company does not expect to realize amounts above its share of the remaining fair value of Energenic's cogeneration assets discussed above. Current losses at Energenic have been offset against the Notes Receivable – Affiliate balance in recent years as our investment in the Energenic affiliate had been reduced to zero as a result of previous losses. • As of December 31, 2021 and 2020, $5.3 million and $2.5 million, respectively, of unsecured notes which accrue interest at variable rates. SJI holds significant variable interests in these entities but is not the primary beneficiary. Consequently, these entities are accounted for under the equity method because SJI does not have both (a) the power to direct the activities of the entity that most significantly impact the entity’s economic performance and (b) the obligation to absorb losses of the entity that could potentially be significant to the entity or the right to receive benefits from the entity that could potentially be significant to the entity. As of December 31, 2021 and 2020, SJI had a net asset of approximately $38.5 million and $106.2 million, respectively, included in Investment in Affiliates on the consolidated balance sheets related to equity method investees; the decrease from prior year is due to the impairment charge related to PennEast noted above. SJI’s maximum exposure to loss from these entities as of December 31, 2021 and 2020 is limited to its combined investments in these entities, which includes related Notes Receivable-Affiliates, in the aggregate amount of $108.5 million and $140.1 million, respectively. DISCONTINUED OPERATIONS - Discontinued Operations consist of the environmental remediation activities related to the properties of SJF and the product liability litigation and environmental remediation activities related to the prior business of Morie. SJF is a subsidiary of EMI, an SJI subsidiary, which previously operated a fuel oil business. Morie is the former sand mining and processing subsidiary of EMI. EMI sold the common stock of Morie in 1996. SJI conducts tests annually to estimate the environmental remediation costs for these properties (see Note 15). Summarized operating results of the discontinued operations for the years ended December 31, were (in thousands, except per share amounts): 2021 2020 2019 Income (Loss) before Income Taxes: Sand Mining $ 854 $ (49) $ (79) Fuel Oil (789) (272) (263) Income Tax (Expense) Benefits (14) 66 70 Income (Loss) from Discontinued Operations — Net $ 51 $ (255) $ (272) Earnings Per Common Share from Discontinued Operations — Net: Basic and Diluted $ — $ — $ — GUARANTEES - SJI has issued guarantees to third parties on behalf of its consolidated subsidiaries. See Note 15. SJG RELATED-PARTY TRANSACTIONS - SJG conducts business with its parent, SJI, and several other related parties. A description of each of these affiliates and related transactions is as follows: SJIEE - a wholly-owned subsidiary of SJI that serves as a holding company for all of SJI’s nonutility operating businesses, including the following subsidiaries: • SJRG - SJG sells natural gas for resale and capacity release to SJRG and also meets some of SJG's gas purchasing requirements by purchasing natural gas from SJRG. • Marina - Prior to the sale of MTF and ACB in February 2020 (see Note 1), SJG provided natural gas transportation services to Marina under BPU-approved tariffs. Millennium - (a joint venture discussed above) - Reads SJG's utility customers’ meters on a monthly basis for a fee. SJIU - a holding company that owns SJG. SJIU incurs corporate-level expenses such as employee salaries and benefits, legal fees, and consulting fees and charges a portion of these expenses to SJG. In addition to the above, SJG provides various administrative and professional services to SJI and each of the affiliates discussed above. Likewise, SJI provides substantial administrative services on SJG's behalf. Amounts due to and due from these related parties for activities that are passed through to customers through billing rates at the same amounts that SJG earns from or is charged by the affiliates are not considered material to SJG's financial statements as a whole. On July 1, 2021, SJG (the lessor) and SJI (the lessee) entered into an intercompany lease agreement for the Company's corporate headquarters in Folsom, NJ (see Note 9). A summary of related party transactions involving SJG, excluding pass-through items, included in SJG's Operating Revenues were as follows (in thousands): 2021 2020 2019 Operating Revenues/Affiliates: SJRG $ 20,067 $ 7,483 $ 5,039 Marina — 60 394 Other 83 80 80 Total Operating Revenues/Affiliates $ 20,150 $ 7,623 $ 5,513 Related-party transactions involving SJG, excluding pass-through items, included in SJG's Cost of Sales and Operating Expenses were as follows (in thousands): 2021 2020 2019 Costs of Sales/Affiliates (Excluding depreciation and amortization) SJRG $ 5,013 $ 4,969 $ 9,612 Operations Expense/Affiliates: SJI (parent company only) $ 25,919 $ 26,173 $ 22,462 SJIU 4,281 3,825 1,833 Millennium 3,458 3,277 3,146 Other 180 1,516 1,680 Total Operations Expense/Affiliates $ 33,838 $ 34,791 $ 29,121

Income Tax Disclosure [Abstract]
INCOME TAXES	INCOME TAXES: SJI files a consolidated federal income tax return and various state income tax returns, some of which are combined or unitary. Total income taxes applicable to operations differ from the tax that would have resulted by applying the statutory Federal income tax rate to pre-tax income for SJI and SJG for the following reasons (in thousands): 2021 2020 2019 SJI (includes SJG and all other consolidated subsidiaries): Tax at Statutory Rate $ 28,481 $ 37,791 $ 20,633 Increase (Decrease) Resulting from: State Income Taxes 11,666 7,896 7,813 Federal and State Valuation Allowance 15,069 7,392 — ESOP Dividend (608) (627) (697) Impairment on Investment in Equity Method Investee 4,172 — — AFUDC (1,327) (1,901) (1,546) Amortization of Excess Deferred Taxes (5,354) (6,174) (3,475) Investment and Other Tax Credits (5,993) (23,439) (953) Other - Net 1,001 1,726 (714) Income Taxes: Continuing Operations 47,107 22,664 21,061 Discontinued Operations 14 (66) (70) Total Income Tax Expense $ 47,121 $ 22,598 $ 20,991 SJG: Tax at Statutory Rate 34,871 30,111 25,245 Increase (Decrease) Resulting from: State Income Taxes 8,311 8,965 9,542 ESOP Dividend (517) (533) (592) AFUDC (461) (821) (591) Amortization of Excess Deferred Taxes (3,075) (3,154) — Other - Net (715) 756 (782) Total Income Tax Expense 38,414 35,324 32,822 The provision for income taxes is comprised of the following (in thousands): SJI (includes SJG and all other consolidated subsidiaries): 2021 2020 2019 Current: Federal $ — $ — $ — State (235) 823 (482) Total Current (235) 823 (482) Deferred: Federal 31,209 3,312 11,171 State 16,133 18,529 10,372 Total Deferred 47,342 21,841 21,543 Income Taxes: Continuing Operations 47,107 22,664 21,061 Discontinued Operations 14 (66) (70) Total Income Tax Expense (Benefit) $ 47,121 $ 22,598 $ 20,991 SJG: Current: Federal $ — $ — $ — State — — — Total Current — — — Deferred: Federal 27,894 23,976 20,744 State 10,520 11,348 12,078 Total Deferred 38,414 35,324 32,822 Total Income Tax Expense $ 38,414 $ 35,324 $ 32,822 For the year ended December 31, 2021, the change in SJI income tax expense in 2021 compared with 2020 increased primarily due to an increase in income before income taxes of consolidated subsidiaries along with less ITC. For the year ended December 31, 2020, the change in SJI Income Tax expense in 2020 compared with 2019 increased primarily due to an increase in income before income taxes in 2020 compared with the prior year along with the valuation allowance discussed below. These increases were partially offset with the benefits from ITC recorded for fuel cell and solar projects that commenced operations in 2020 (see Note 1). For the year ended 2019, changes in SJI tax expense correlated with changes in income before income taxes. For the years ended 2021, 2020 and 2019, changes in SJG tax expense correlated with changes in income before income taxes. CARES ACT - Given the impact that COVID-19 has had on the economy, on March 27, 2020 the President signed into law the CARES Act, an economic stimulus package in response to the COVID-19 global pandemic, as a way to provide relief to both businesses and individuals affected by the virus. The CARES Act contains several corporate tax provisions that impacted SJI and SJG, including deferring payments on social security taxes for employees and other employee retention credits. These impacts of the CARES Act, and these provisions, did not have a material effect on income tax expense or deferred tax assets/liabilities. DEFERRED TAX ASSETS AND LIABILITIES - The net tax effect of temporary differences between the carrying amounts of assets and liabilities for financial reporting and income tax purposes resulted in the following net deferred tax assets and liabilities for SJI and SJG at December 31 (in thousands): SJI (includes SJG and all other consolidated subsidiaries): 2021 2020 Deferred Tax Assets: Net Operating Loss Carryforward $ 179,518 $ 141,252 Investment and Other Tax Credits 251,541 243,827 Deferred State Tax 30,567 24,338 Income Taxes Recoverable Through Rates 88,201 92,739 Pension & Other Post Retirement Benefits 16,575 34,558 Deferred Revenues 5,355 4,530 Provision for Uncollectibles 11,979 8,763 Other 15,461 17,691 Total Deferred Tax Asset 599,197 567,698 Valuation Allowance (22,484) (7,392) Total Deferred Tax Asset, net of Valuation Allowance $ 576,713 $ 560,306 Deferred Tax Liabilities: Book versus Tax Basis of Property $ 586,081 $ 512,357 Deferred Gas Costs - Net 14,102 13,737 Derivatives / Unrealized Gain 2,567 1,215 Environmental Remediation 49,378 50,262 Deferred Regulatory Costs 19,165 13,360 Budget Billing - Customer Accounts 6,310 5,248 Deferred Pension & Other Post Retirement Benefits 21,973 33,307 CIP 5,196 6,178 Equity In Loss Of Affiliated Companies 3,744 16,019 Goodwill Amortization 41,517 28,013 Other 8,176 8,977 Total Deferred Tax Liability $ 758,209 $ 688,673 Deferred Tax Liability - Net $ 181,496 $ 128,367 SJG: Deferred Tax Assets: Net Operating Loss and Tax Credits $ 27,688 $ 35,301 Deferred State Tax 25,039 22,918 Provision for Uncollectibles 6,997 4,887 Income Taxes Recoverable Through Rates 54,900 58,573 Pension & Other Post Retirement Benefits 8,742 20,857 Deferred Revenues 5,479 4,739 Other 2,717 2,813 Total Deferred Tax Assets $ 131,562 $ 150,088 Deferred Tax Liabilities: Book Versus Tax Basis of Property $ 456,216 $ 435,764 Deferred Fuel Costs - Net 18,015 10,189 Environmental Remediation 45,496 46,857 Deferred Regulatory Costs 17,209 15,087 Deferred Pension & Other Post Retirement Benefits 13,064 21,398 Budget Billing - Customer Accounts 6,310 5,248 Section 461 Prepayments 1,528 1,469 CIP 5,196 6,178 Other 11,930 11,507 Total Deferred Tax Liabilities $ 574,964 $ 553,697 Deferred Tax Liability - Net $ 443,402 $ 403,609 SJG is included in the consolidated federal income tax return filed by SJI. The actual taxes, including credits, are allocated by SJI to its subsidiaries, generally on a separate return basis except for net operating loss and credit carryforwards. As of December 31, 2021 and 2020, there were no income taxes due to or from SJI. NOL AND ITC CARRYFORWARD - As of December 31, 2021, SJI has the following federal and state net operating loss carryforwards (in thousands): Net Operating Loss Carryforwards Expire in: Federal State 2031 $ — $ 11,395 2032 21,541 3,108 2033 57,515 18,557 2034 107,043 13,658 2035 51,385 25,063 2036 102,256 126,344 2037 85,444 96,697 2038 — 127,846 2039 — 129,940 2040 — 82,476 2041 — 132,396 Indefinite 161,029 — $ 586,213 $ 767,480 As of December 31, 2021, SJI has the following investment tax credit carryforwards (in thousands): Expire in: Investment Tax Credit Carryforwards 2030 $ 11,628 2031 25,664 2032 32,031 2033 45,606 2034 37,699 2035 45,005 2036 11,744 2037 636 2038 93 2039 — 2040 23,814 2041 4,364 $ 238,284 SJI and SJG also have federal research and development credits of $7.7 million and $3.2 million, respectively, which will expire between 2031 and 2040. SJI and SJG have state credits of $6.8 million and $3.8 million, respectively, that will expire between 2024 and 2041. As of December 31, 2021 and 2020, SJG has total federal net operating loss carryforwards of $33.6 million and $67.7 million, respectively, that will expire between 2036 and 2037. As of December 31, 2021 and 2020, SJG has a state net operating loss carryforward of $192.0 million and $212.8 million, respectively, that will expire between 2036 and 2039. A valuation allowance is recorded when it is more likely than not that any of SJI's or SJG's deferred tax assets will not be realized. As of December 31, 2021 and 2020, SJI had a total federal and state valuation allowance of $22.5 million and $7.4 million, respectively, recorded on the consolidated balance sheets. SJI recorded a valuation allowance of $14.2 million in 2021 against the federal deferred tax asset related to the capital loss that resulted from the other-than-temporary impairment charge taken on the Company's investment in PennEast (see Note 3). SJI recorded a valuation allowance of $7.4 million in 2020 related to certain state net operating loss and state credit carryforwards expected to expire prior to being fully utilized. SJG believes that they will generate sufficient future taxable income to realize the income tax benefits related to their net deferred tax assets. A reconciliation of the beginning and ending amount of unrecognized tax benefits for the years ended December 31, is as follows (in thousands): SJI (includes SJG and all other consolidated subsidiaries): 2021 2020 2019 Balance at January 1, $ 2,372 $ 1,566 $ 1,147 Increase as a result of tax positions taken in prior years 14,611 806 419 Balance at December 31, $ 16,983 $ 2,372 $ 1,566 SJG: Balance at January 1, $ 1,129 $ 1,104 $ 1,063 Increase as a result of tax position taken in prior years 14,023 25 41 Balance at December 31, $ 15,152 $ 1,129 $ 1,104 The total unrecognized tax benefits reflected in the table above exclude $1.9 million, $0.9 million and $0.8 million of accrued interest and penalties for each of the years ended December 31, 2021, 2020 and 2019 for both SJI and SJG. The amount of unrecognized tax benefits that, if recognized, would affect the effective tax rate is not significant. The Company's policy is to record interest and penalties related to unrecognized tax benefits as interest expense and other expense, respectively. These amounts were not significant in 2021, 2020 or 2019. The majority of the increased tax position in 2021 and 2020 is attributable to research and development credits and specified liability loss carryback claims. The Company does not anticipate any significant changes in the total unrecognized tax benefits within the next 12 months. The Company evaluates certain tax benefits that have been recorded in the financial statements for uncertainties. In 2021, SJG recorded a reserve of $13.9 million for a portion of tax benefits related to tax positions taken in prior years. The reserve is recorded in Other Noncurrent Liabilities in the consolidated balance sheets as of December 31, 2021. The amount of income taxes we pay is subject to ongoing audits by federal and state tax authorities, which could result in proposed assessments. Future results may include favorable or unfavorable adjustments to our estimated tax liabilities in the period any assessments are determined or resolved or as such statutory audit periods are closed. We are not aware of any other matters that would result in significant changes to the amount of unrecognized income tax benefits reflected on the consolidated balance sheets as of December 31, 2021. The unrecognized tax benefits are primarily related to an uncertainty of state income tax issues relating to the Company's nexus in certain states, tax credits and federal carryback claims. The IRS has finalized its audits of the Company's consolidated federal income tax returns through 2013. Federal income tax returns from 2014 forward and state income tax returns from 2013 forward are open and subject to examination.

There were 2,339,139 shares of SJG's common stock (par value $2.50 per share) outstanding as of December 31, 2021. SJG did not issue any new shares during the period. SJIU owns all of the outstanding common stock of SJG. AUTHORIZED SHARES - On October 16, 2020, SJI filed an amendment to its Certificate of Incorporation that increased the authorized number of shares of its common stock from 120,000,000 to 220,000,000 and the aggregate number of shares authorized to be issued by SJI from 122,500,000 to 222,500,000. ATM PUBLIC EQUITY OFFERING - • In April 2020, SJI entered into an ATM Equity Offering Sales Agreement (the "Sales Agreement") to sell, from time to time, shares of the Company’s common stock, par value $1.25 per share, having an aggregate sale price up to $200.0 million, through an “at-the-market” equity offering program. In June 2020, 8,122,283 shares were sold pursuant to the Sales Agreement at an average market price of approximately $24.62 for total net proceeds of $198.0 million after deducting commissions and other general & administrative expenses. These sales exhausted the shares that were available for sale under the Sales Agreement. The Company used the net proceeds from this offering for general corporate purposes. COMMON STOCK PUBLIC OFFERING - • On March 22, 2021, SJI offered 10,250,000 shares of its common stock, par value $1.25 per share, at a public offering price of $22.25 per share. Of the offered shares, 362,359 shares were issued at closing. The remaining 9,887,641 shares of common stock ("Forward Shares") are to be sold by Bank of America, N.A., as forward seller, pursuant to a forward sale agreement. SJI has an option to settle the forward sale agreement by delivering newly issued shares of SJI common stock and receive proceeds, subject to certain adjustments, from the sale of those shares, assuming one or more future physical settlements of the forward sale agreement, no later than March 2022. SJI may also choose to settle the forward sale contract with a cash payment, or multiple cash payments, no later than March 2022. In the event SJI elects to settle all or a portion of the forward sale contract with a cash payment, no additional shares of SJI common stock would be issued under the forward sale contract for the portions that were cash settled. • On March 25, 2021, 1,537,500 shares pursuant to the underwriters’ option as part of the underwriting agreement for the above offering of shares were issued at the same public offering price of $22.25. • The issuance of a total 1,899,859 shares in March 2021 resulted in gross proceeds of $42.3 million, with net proceeds, after deducting underwriting discounts and commissions as well as legal fees, totaling $40.6 million. • On December 27, 2021, 4,891,579 Forward Shares were issued under the forward sale agreement for net proceeds of $100.0 million, The forward price used to determine cash proceeds received by SJI was calculated based on the initial forward sale price, as adjusted for underwriting fees, interest rate adjustments as specified in the forward sale agreement and any dividends paid on our common stock during the forward period. EQUITY UNITS PUBLIC OFFERING - • On March 22, 2021, SJI issued and sold 6,000,000 Equity Units, initially consisting of Corporate Units ("2021 Corporate Units"). Each 2021 Corporate Unit has a stated amount of $50 and is comprised of (a) a purchase contract obligating the holder to purchase from the Company for a price in cash of $50, on the purchase contract settlement date, or April 1, 2024, subject to earlier termination or settlement, a certain number of shares of Common Stock; and (b) a 1/20, or 5%, undivided beneficial ownership interest in $1,000 principal amount of the Company’s 2021 Series B 1.65% Remarketable Junior Subordinated Notes due 2029 (for this section, the “Notes”). In addition to interest payable under the Notes, holders of the 2021 Corporate Units will be entitled to receive quarterly contract adjustment payments at a rate of 7.10% per year on the stated amount of $50 per 2021 Corporate Unit, subject to the Company’s right to defer such contract adjustment payments. No deferral period will extend beyond the purchase contract settlement date. The contract adjustment payments are payable quarterly on January 1, April 1, July 1 and October 1 of each year. The contract adjustment payments will be subordinated to all of the Company's existing and future “Priority Indebtedness” and will be structurally subordinated to all liabilities of our subsidiaries. The present value of the contract adjustment payments due through April 1, 2024 was $69.5 million and is charged to Shareholders’ Equity, with an offsetting credit to Other Current and Noncurrent Liabilities on the consolidated balance sheets. These liabilities are accreted over the life of the purchase contract by interest charges to the consolidated statements of income based on a constant rate calculation. Total interest recorded in 2021 was $0.9 million related to these liabilities and is recorded within Interest Charges on the consolidated statements of income. Subsequent contract adjustment payments reduce this liability. The balance recorded in Other Current and Noncurrent Liabilities was $23.8 million and $34.6 million, respectively, as of December 31, 2021. This offering resulted in gross proceeds of approximately $300.0 million, with net proceeds, after deducting underwriting discounts and commissions, of $291.0 million. As of December 31, 2021, the net proceeds, after amortization of the underwriting discounts, are recorded as Long-Term Debt on the consolidated balance sheets. • On April 1, 2021, the underwriters purchased an additional 700,000 Equity Units as part of their option under the above offering to purchase an additional 900,000 Equity Units. Gross proceeds were approximately $35.0 million, with net proceeds, after deducting underwriting discounts and commissions, of approximately $34.0 million. As of December 31, 2021, the net proceeds, after amortization of the underwriting discounts, are recorded as Long-Term Debt on the consolidated balance sheets. CONVERTIBLE UNITS - • In 2018, SJI issued and sold 5,750,000 Equity Units, initially in the form of Corporate Units ("2018 Corporate Units"), which included 750,000 of 2018 Corporate Units pursuant to the underwriters’ option. Each 2018 Corporate Unit had a stated amount of $50 and was comprised of (a) a purchase contract obligating the holder to purchase from the Company, and for the Company to sell to the holder for a price in cash of $50, on the purchase contract settlement date, or April 15, 2021, subject to earlier termination or settlement, a certain number of shares of common stock; and (b) a 1/20, or 5%, undivided beneficial ownership interest in $1,000 principal amount of SJI’s 2018 Series A 3.70% Remarketable Junior Subordinated Notes due 2031 (the "Series A Junior Subordinated Notes"). SJI paid the holder quarterly contract adjustment payments at a rate of 3.55% per year on the stated amount of $50 per Equity Unit, in respect of each purchase contract, subject to the Company's right to defer these payments. The net proceeds, after amortization of the underwriting discounts, are recorded as Long-Term Debt on the consolidated balance sheets. • On March 25, 2021, the Company finalized the remarketing of the $287.5 million of Series A Junior Subordinated Notes. The interest rate on the Series A Junior Subordinated Notes has been reset to 5.020% per year, and this reset rate became effective on April 15, 2021 (see below). Interest on the Series A Junior Subordinated Notes will be payable semi-annually on April 15 and October 15, commencing on April 15, 2021, and at maturity. As a result, these notes continue to be recorded as Long-Term Debt on the consolidated balance sheets as of December 31, 2021. • On April 1, 2021, the Company announced the settlement rate for the stock purchase contracts that are components of the 2018 Corporate Units with holders of the 2018 Corporate Units to receive 1.7035 shares of SJI common stock for each stock purchase contract that they hold, with cash to be paid in lieu of any fractional shares. The settlement rate was set to be based upon the original settlement rate of 1.6949 shares, as adjusted for certain corporate events since original issuance. Consequently, on April 15, 2021, each holder of the 2018 Corporate Units on that date, following payment of $50.00 for each unit held, received 1.7035 shares of the Company’s common stock for each such unit. As a result of settlement of the outstanding stock purchase contracts, on April 15, 2021, the Company received approximately $287.5 million in exchange for approximately 9.8 million shares of common stock. Additionally, each 2018 Corporate Unit holder of record on April 1, 2021, received the final quarterly cash distribution of $0.90625 per 2018 Corporate Unit and received any remaining amounts from the treasury portfolio that was purchased in connection with the remarketing described above, as well as any earnings from the reinvestment of that treasury portfolio when it matured. The convertible units consisted of the following (in thousands): December 31, 2021 December 31, 2020 Principal amount: 2021 Series B Remarketable Junior Subordinated Notes due 2029 2018 Series A Remarketable Junior Notes due 2031 Principal (A) $ 335,000 $ 287,500 Unamortized debt discount and issuance costs (A) $ 9,110 $ 7,181 Net carrying amount $ 325,890 $ 280,319 Carrying amount of the equity component (B) $ — $ — (A) Included in the consolidated balance sheets within Long-Term Debt. (B) There is no equity portion as of December 31, 2021 and 2020 for these Notes. During 2021, 2020, and 2019, the Company recognized $17.9 million, $10.7 million and $10.7 million, respectively, of coupon interest expense, all of which was included in Interest Charges on the consolidated statements of income. During those periods, the amortization of debt discount and issuance costs was not material. As of December 31, 2021, the effective interest rate was 2.1% on the 2021 Notes and 5.0% on the 2018 Notes. EPS — SJI's basic EPS is based on the weighted-average number of common shares outstanding. SJI's diluted EPS includes consideration of the effect of SJI's restricted stock as dis cussed in Note 2, along with the impact of the Forward Shares, Equity Units and Convertible Units discussed above, accounted for under the treasury stock method. The incremental shares required for inclusion in the denominator for the diluted EPS calculation were 851,364, 141,076, and 123,021 shares for the years ended December 31, 2021, 2020, and 2019, respectively. DRP — SJI offers a DRP which allows participating shareholders to purchase shares of SJI common stock by automatic reinvestment of dividends or optional purchases. SJI currently purchases shares on the open market to fund share purchases by DRP participants, and as a result SJI did not raise any equity capital through the DRP in 2021, 2020 or 2019. RETAINED EARNINGS — The Utilities are limited by their regulatory authorities on the amount of cash dividends or other distributions they are able to transfer to their parent, specifically if such dividends or other distributions could impact their capital structure. In addition, SJG's First Mortgage Indentures contain a restriction regarding the amount of cash dividends or other distributions that it may pay. As of December 31, 2021, this loan restriction does not affect the amount that may be distributed from SJG's retained earnings. ADDITIONAL INVESTMENT BY SHAREHOLDER — SJG received $40.0 million and $109.5 million in equity contributions from SJI in 2021 and 2020, respectively. There were no equity contributions to SJG in 2019. Future equity contributions will occur on an as needed basis.

Segment Reporting [Abstract]
SEGMENTS OF BUSINESS	SEGMENTS OF BUSINESS: ASC 280 , Segment Reporting, establishes standards for reporting information about operating segments and requires that a public business enterprise report financial and descriptive information about its reportable operating segments. Operating segments are defined as components of an enterprise for which separate financial information is available that is regularly evaluated by the CODM in deciding how to allocate resources and in assessing performance. Beginning with the first quarter of 2021, our internal management reporting, specifically around our nonutility businesses, changed primarily due to recent acquisitions and new product lines entered into. These were primarily within the fuel cell, solar, RNG, and retail businesses. See Notes 1 and 20 for information about these acquisitions. As a result of these changes in our businesses, the Company realigned its operating segments. The realigned segments reflect the financial information regularly evaluated by the CODM, which for SJI is the Company's Chief Executive Officer. The operating segments are as follows: • SJG utility operations consist primarily of natural gas distribution to residential, commercial and industrial customers in southern New Jersey. • ETG utility operations consist primarily of natural gas distribution to residential, commercial and industrial customers in northern and central New Jersey. • ELK utility operations consist of natural gas distribution to residential, commercial and industrial customers in Maryland. As discussed in Note 1, on July 31, 2020, SJI sold ELK to a third-party buyer. • Wholesale energy operations include the activities of SJRG and SJEX. • Retail services operations includes the activities of SJE, SJESP and SJEI, as well as our equity interest in Millennium. • Renewables consists of: ◦ The Catamaran joint venture, which owns Annadale and Bronx Midco, along with a solar project in Massachusetts. ◦ Solar-generation sites located in New Jersey, and three legacy solar projects, one of which was sold during the first quarter of 2020. ◦ The activities of ACLE, BCLE, SCLE and SXLE, which have all ceased operations (see Note 1). ◦ MTF and ACB, which were sold in the first quarter of 2020. • Decarbonization consists of: ◦ SJI Renewables Energy Ventures, LLC, which includes our equity interest in REV, which is included in Equity in (Loss) Earnings of Affiliated Companies on the consolidated statements of income. ◦ SJI RNG Devco, LLC, which includes costs incurred to develop renewable natural gas operations at certain dairy farms along with the related development rights acquired in 2020. • Midstream invests in infrastructure and other midstream projects, including an investment in PennEast for which development ceased in September 2021 (see Note 3). • Corporate & Services segment includes costs related to financing, acquisitions and divestitures, and other unallocated costs. • Intersegment represents intercompany transactions among the above SJI consolidated entities. SJI groups its utility businesses under its wholly-owned subsidiary SJIU. This group consists of the gas utility operations of SJG and ETG and, until its sale, ELK. SJI groups its nonutility operations into separate categories: Energy Management; Energy Production; Midstream; and Corporate & Services. Energy Management includes wholesale energy operations and retail services. Energy Production includes renewables and decarbonization. The accounting policies of the segments are the same as those described in the summary of significant accounting policies. See Note 1. Information about SJI’s operations in different reportable operating segments is presented below (in thousands). All prior periods were revised to conform to the new segment alignment noted above. 2021 2020 2019 Operating Revenues: SJI Utilities: SJG Utility Operations $ 618,426 $ 571,787 $ 569,226 ETG Utility Operations 360,024 349,392 325,133 ELK Utility Operations — 4,793 7,949 Subtotal SJI Utilities 978,450 925,972 902,308 Energy Management: Wholesale Energy Operations 993,938 571,590 607,093 Retail Services 17,889 38,251 83,845 Subtotal Energy Management 1,011,827 609,841 690,938 Energy Production: Renewables 24,038 15,617 48,748 Decarbonization — — — Subtotal Energy Production 24,038 15,617 48,748 Corporate & Services 59,480 54,422 43,901 Subtotal 2,073,795 1,605,852 1,685,895 Intersegment Sales (81,799) (64,469) (57,269) Total Operating Revenues $ 1,991,996 $ 1,541,383 $ 1,628,626 2021 2020 2019 Operating Income: SJI Utilities: SJG Utility Operations $ 199,214 $ 171,235 $ 147,494 ETG Utility Operations 95,509 89,638 69,315 ELK Utility Operations — 372 721 Subtotal SJI Utilities 294,723 261,245 217,530 Energy Management: Wholesale Energy Operations 48,406 33,869 439 Retail Services 1,838 (3,153) (2,764) Subtotal Energy Management 50,244 30,716 (2,325) Energy Production: Renewables 4,569 (5,602) (4,248) Decarbonization (120) — — Subtotal Energy Production 4,449 (5,602) (4,248) Midstream — (467) (154) Corporate and Services (296) (3,670) (9,598) Total Operating Income $ 349,120 $ 282,222 $ 201,205 Depreciation and Amortization: SJI Utilities: SJG Utility Operations $ 127,440 $ 101,711 $ 93,910 ETG Utility Operations 70,643 57,967 29,051 ELK Utility Operations — 354 469 Subtotal SJI Utilities 198,083 160,032 123,430 Energy Management: Wholesale Energy Operations 92 69 89 Retail Services 537 — — Subtotal Energy Management 629 69 89 Energy Production: Renewables 5,106 5,647 4,591 Decarbonization — — — Subtotal Energy Production 5,106 5,647 4,591 Corporate and Services 7,834 4,899 5,275 Total Depreciation and Amortization $ 211,652 $ 170,647 $ 133,385 Interest Charges: SJI Utilities: SJG Utility Operations $ 39,133 $ 33,388 $ 31,654 ETG Utility Operations 34,155 29,997 27,352 ELK Utility Operations — 21 8 Subtotal SJI Utilities 73,288 63,406 59,014 Energy Management: Retail Services 180 43 (142) Subtotal Energy Management 180 43 (142) Energy Production: Renewables 4,660 4,001 8,637 Decarbonization 1,513 — — Subtotal Energy Production 6,173 4,001 8,637 Midstream 1,704 2,513 2,262 Corporate and Services 52,636 55,873 57,858 Subtotal 133,981 125,836 127,629 Intersegment Borrowings (6,851) (7,302) (13,152) Total Interest Charges $ 127,130 $ 118,534 $ 114,477 2021 2020 2019 Income Taxes: SJI Utilities: SJG Utility Operations $ 38,414 $ 35,324 $ 32,822 ETG Utility Operations 15,053 12,465 7,761 ELK Utility Operations — 186 146 Subtotal SJI Utilities 53,467 47,975 40,729 Energy Management: Wholesale Energy Operations 14,035 9,666 574 Retail Services 1,537 287 (262) Subtotal Energy Management 15,572 9,953 312 Energy Production: Renewables (8,124) (24,132) (3,308) Decarbonization 146 — — Subtotal Energy Production (7,978) (24,132) (3,308) Midstream (329) (217) (135) Corporate and Services (13,625) (10,915) (16,537) Total Income Taxes $ 47,107 $ 22,664 $ 21,061 Property Additions: SJI Utilities: SJG Utility Operations $ 243,699 $ 266,009 $ 264,235 ETG Utility Operations 224,019 197,730 197,457 ELK Utility Operations — 970 2,762 Subtotal SJI Utilities 467,718 464,709 464,454 Energy Management: Wholesale Energy Operations 6 6 7 Retail Services 55 — 4 Subtotal Energy Management 61 6 11 Energy Production: Renewables 64,906 85,280 229 Decarbonization 29,600 — — Subtotal Energy Production 94,506 85,280 229 Midstream 29 131 46 Corporate and Services 4,254 2,799 1,554 Total Property Additions $ 566,568 $ 552,925 $ 466,294 2021 2020 Identifiable Assets: SJI Utilities: SJG Utility Operations $ 3,767,897 $ 3,522,265 ETG Utility Operations 2,788,465 2,561,067 Subtotal SJI Utilities 6,556,362 6,083,332 Energy Group: Wholesale Energy Operations 278,995 195,882 Retail Services 25,741 29,687 Subtotal Energy Group 304,736 225,569 Energy Services: Renewables 195,791 153,018 Decarbonization 138,787 40,482 Subtotal Energy Services 334,578 193,500 Midstream 8,970 92,208 Corporate and Services 370,899 318,095 Intersegment Assets (266,920) (225,331) Discontinued Operations 47 1,775 Total Identifiable Assets $ 7,308,672 $ 6,689,148

Leases [Abstract]
LEASES	LEASES: Lessee: As discussed in Note 1, SJI, directly and through certain of its subsidiaries, including SJG, is a lessee of real estate (land and building), communication towers and office equipment. SJI currently does not have any contracts where it is considered the lessor. The lease-related amounts in the balance sheets where SJG is a lessee at December 31, 2021 and 2020, and activity and costs during the periods presented are not material for SJG and, therefore, the disclosures included herein reflect those of SJI only, which includes SJG as well as all other consolidated subsidiaries. However, SJG is considered the lessor in a lease with SJI as described below under "Lessor." SJI has two real estate leases that are classified as finance leases, which result in the recognition of interest expense on the lease liability per the effective interest model and amortization of the ROU asset on a straight-line basis over the respective lease terms: • As part of the Annadale acquisition in 2020 (see Note 20), a real estate lease was acquired resulting in the recognition of an ROU asset and lease liability upon acquisition, each of $3.1 million, with a lease term of 35 years. • As part of the acquisitions of solar projects (see Notes 1 and 20), a land lease was acquired with one of the projects resulting in the recognition of an ROU asset and a lease liability upon acquisition, each of $2.6 million, with a lease term of 20 years. SJI has the following real estate leases that are classified as operating leases: • As part of the acquisition of the Bronx Midco fuel cell project (see Note 20), a land lease was acquired resulting in the recognition of an ROU asset and a lease liability upon acquisition, each of $6.7 million. The lease cost associated with this lease is recognized on a straight-line basis over the lease term of 35 years. • On July 1, 2021, SJG (as lessor) and SJI (as lessee) entered into an intercompany lease agreement for the Company's corporate headquarters in Folsom, NJ. The rent income and the rent expense associated with this lease are recognized on a straight-line basis over the lease term. The rent income and rent expense for SJG and SJI, respectively, for 2021 was $1.0 million. The rent income and rent expense, as well as certain other balances related to this lease, were eliminated in SJI’s consolidated financial statements. • As part of the development of renewable natural gas operations at dairy farms, SJI RNG Devco entered into several real estate lease agreements in 2021, resulting in the recognition of ROU assets and liabilities, each of $4.8 million. The lease costs associated with these leases are recognized on a straight-line basis over the lease terms of 20 years. • Marina entered into a real estate lease related to a solar project in Massachusetts in 2021, resulting in the recognition of an ROU asset and liability, each of $1.7 million. The lease costs associated with these leases are recognized on a straight-line basis over the lease terms of 35 years. • The remainder of SJI's real estate leases are comprised primarily of office space and payment centers. Real estate operating leases generally have a lease term between 3 and 35 years. Other operating leases primarily consist of communication towers and office equipment, which generally have a lease term of 5 years.

Supplemental cash flow and other information The supplemental cash flow information related to operating leases for SJI (including SJG and all other consolidated subsidiaries) for the years ended December 31 were as follows (in thousands): 2021 2020 Operating cash flows from operating leases $ 1,076 $ 1,151 Operating cash flows from finance leases $ 190 $ 64 Financing cash flows from finance leases $ 55 $ — 2021 2020 ROU assets obtained in exchange for operating lease liabilities $ 15,028 $ — ROU assets obtained in exchange for finance lease liabilities $ 2,625 $ 3,057 The following table represents the weighted-average remaining lease term and weighted-average discount rate: Weighted average remaining lease term December 31, 2021 December 31, 2020 SJI (includes SJG and all other consolidated subsidiaries): Operating leases 29.2 years 4.7 years Finance lease 33.7 years 34.7 years Weighted average discount rate December 31, 2021 December 31, 2020 SJI (includes SJG and all other consolidated subsidiaries): Operating leases 4.0% 3.0% Finance lease 4.3% 5.0% SJG The lease-related balances as the lessee at December 31, 2021 and 2020, and activity and costs during the periods presented are not material for SJG. Lessor : As discussed above, SJG executed a lease agreement with SJI for the use of SJI's corporate headquarters in Folsom, NJ. This lease is classified as an operating lease by SJG with a lease term of 10 years, which includes the noncancelable period of 5 years plus the first 5-year renewal option. There are nine additional options to renew the lease after the original term expires, totaling an additional 45 years, if renewed. After considering various entity, contract, asset and market factors, SJG concluded that the least term is 10 years as it is not reasonably certain that SJI will exercise renewal options past that point. Rent income of $1.0 million was recorded by SJG on the consolidated statements of income for 2021. The future minimum payments to be recovered by SJG on this operating lease are follows (in thousands): Year ended December 31, 2022 $ 1,965 2023 $ 1,965 2024 $ 1,965 2025 $ 1,965 2026 $ 1,965 Thereafter $ 8,841 Total $ 18,666

RATES AND REGULATORY ACTIONS

RATES AND REGULATORY ACTIONS	12 Months Ended
	Dec. 31, 2021
Public Utilities, General Disclosures [Abstract]
RATES AND REGULATORY ACTIONS	RATES AND REGULATORY ACTIONS: SJG and ETG are subject to the rules and regulations of the BPU. SJG: Base Rate Case - In March 2020, SJG filed a base rate case with the BPU to increase its base rates in order to obtain a return on new capital investments made by SJG since the settlement of its last base rate case in 2017. In September 2020, the BPU approved the settlement of SJG's rate case petition, resulting in an increase in annual revenues from base rates effective October 1, 2020 of $39.5 million, including an approved after-tax rate of return of 6.9%, with a return on equity of 9.6% and a common equity component of 54.0%. Included was recovery of $10.1 million in costs related to a previous project to re-power the for mer BL England facility with natural gas (see Note 11) and $5.1 million of costs related to the ERIP (see Note 12). These costs are to be amortized over a five year period commencing October 1, 2020. Periodic Rate Mechanisms : SJG's tariff, a schedule detailing the terms, conditions and rate information applicable to its various types of natural gas service, as ap proved by the BPU, has several primary rate mechanisms. The current effective rate mechanisms reflected in SJG’s tariff, and regulatory actions regarding each for the preceding three years, are described below (filings and petitions described below are still pending unless otherwise indicated). The approvals for the BGSS and clauses under the SBC discussed below do not impact SJG's earnings. They represent changes in the cash requirements of SJG corresponding to cost changes and/or previously over/under recoveries from ratepayers associated with each respective mechanism. BGSS Clause - The BGSS price structure allows SJG to recover all prudently incurred gas costs. Changes to BGSS charges to customers can occur either monthly or periodically (annually). Monthly changes in BGSS charges are applicable to large use customers and are pursuant to a BPU-approved formula based on commodity market prices. Periodic changes in BGSS charges are applicable to lower usage customers, which include all of SJG's residential customers, and those rates are evaluated at least annually by the BPU. However, to some extent, more frequent rate changes to the periodic BGSS are allowed. SJG collects gas costs from customers on a forecasted basis and defers periodic over/under recoveries to the following BGSS year, which runs from October 1 through September 30. If SJG is in a net cumulative undercollected position, gas costs deferrals are reflected on the consolidated balance sheets as a regulatory asset. If SJG is in a net cumulative overcollected position, amounts due back to customers are reflected on the consolidated balance sheets as a regulatory liability. SJG pays interest on net overcollected BGSS balances at the rate of return on rate base utilized by the BPU to set rates in the most recently concluded base rate proceeding. • 2019-2020 BGSS year - In September 2019, the BPU approved, on a provisional basis, a $27.6 million decrease in gas cost recoveries, effective October 1, 2019. This was approved as a final rate in the first quarter of 2020 with no changes from the provisional rate. • 2020-2021 BGSS year - In September 2020, the BPU approved, on a provisional basis, a $59.4 million decrease in gas cost recoveries, effective October 1, 2020 based on SJG's June 2020 BGSS filing. Although SJG's June 2020 BGSS filing included consideration of $22.9 million of costs requested to be recovered over a two-year period related to a previous dispute on a long-term gas supply contract that was settled during 2019 ("supply contract costs"), the provisional rate adjustments effective October 1, 2020 included the temporary removal of these amounts to allow for a further review of these costs during the course of this proceeding. In May 2021, the BPU approved these provisional rates, adjusted for a two-year amortization of the supply contract costs through September 30, 2022 as final effective June 1, 2021. • 2021-2022 BGSS year - In November 2021, the BPU approved, on a provisional basis, a $36.2 million increase in gas cost recoveries, effective December 1, 2021. The approval extended the amortization of the supply contract costs to September 30, 2024. In addition, as allowed under the BGSS clause, in November 2021, SJG issued a notice to the BPU of SJG's intent to self-implement a BGSS rate adjustment representing an additional 5% increase of the monthly bill of a typical residential customer, effective December 1, 2021, for a total increase of $56.6 million in revenues. CIP - The primary purpose of the CIP is to promote conservation efforts, without negatively impacting financial stability, and to base SJG's profit margin on the number of customers rather than the amount of natural gas distributed to customers. Each CIP year begins October 1 and ends September 30 of the subsequent year. On a monthly basis during the CIP year, SJG records adjustments to earnings based on weather and customer usage factors, as incurred. Subsequent to each year, SJG makes filings with the BPU to review and approve amounts recorded under the CIP. BPU-approved cash inflows or outflows generally will not begin until the next CIP year. • 2019-2020 CIP year - In September 2019, the BPU approved, on a provisional basis, a total $7.6 million net decrease in revenues, which included a $32.3 million decrease in non-weather related revenues and a $24.7 million increase in weather related revenues, effective October 2019. This was approved as a final rate in the first quarter of 2020 with no changes from the provisional rate. • 2020-2021 CIP year - In September 2020, the BPU approved, on a provisional basis, a $27.4 million increase in revenues, effective October 1, 2020, which included a $17.3 million increase in weather-related revenues and a $10.1 million increase in non-weather-related revenues. This was approved as a final rate in the second quarter of 2021 with no changes from the provisional rate. • 2021-2022 CIP year - In November 2021, the BPU approved, on a provisional basis, a $15.3 million decrease in revenues, effective December 1, 2021, which included a $6.5 million decrease in weather-related revenues and a $8.8 million decrease in non-weather related revenues. AIRP - In October 2016, the BPU approved an extension of the AIRP for a five-year period commencing October 1, 2016 through September 30, 2021, with authorized investments of up to $302.5 million to continue replacing cast iron and unprotected bare steel mains and associated services ("AIRP II"). Pursuant to the Order, AIRP II investments are to be recovered through annual base rate adjustments. • September 2019 - The BPU approved an increase in annual revenues from base rates of $6.7 million to reflect the roll-in of $64.5 million of in service AIRP II investments from July 1, 2018 through June 30, 2019, effective October 1, 2019. • September 2020 - The BPU approved an increase in annual revenues from base rates of $6.4 million to reflect the roll-in of $58.8 million of AIRP II in service investments for the period July 1, 2019 through June 30, 2020, effective October 1, 2020. • December 2021 - The BPU approved an increase in annual revenues from base rates of $6.7 million to reflect the roll-in of $69.0 million of AIRP II in service investments for the period July 1, 2020 through September 30, 2021. The AIRP II Program concluded September 30, 2021 and the final rate adjustment for this program became effective January 1, 2022. SHARP - SHARP replaces low pressure distribution mains and services with high pressure mains and services in coastal areas that are susceptible to flooding during major storm events. SHARP investments are to be recovered through annual base rate adjustments. Phase one of SJG’s initial SHARP expired in June 2017. In May 2018, the BPU approved SJG's petition to continue its storm hardening efforts under a second phase of SHARP ("SHARP II"). SHARP II is a three-year program, with a total investment level of approximately $100.3 million, focused on four system enhancement projects within the coastal regions. • April 2019 - SJG submitted its first annual filing, pursuant to the May 2018 BPU approval of the SHARP II, seeking a base rate adjustment to increase annual revenues by approximately $3.0 million to reflect the roll-in of approximately $28.3 million of SHARP II investments placed in service during June 1, 2018 through June 30, 2019. • September 2019 - The BPU approved an increase in annual revenues from base rates of $2.9 million to reflect the roll-in of $27.4 million of in service SHARP II investments made from July 1, 2018 through June 30, 2019, effective October 1, 2019. • September 2020 - The BPU approved an increase in annual revenues from base rates of $3.7 million to reflect the roll-in of $33.3 million of SHARP II in service investments for the period July 1, 2019 through June 30, 2020, effective October 1, 2020. • September 2021 - The BPU approved an increase in annual revenues from base rates of $2.2 million to reflect the roll-in of $22.8 million of SHARP II in service investments for the period July 1, 2020 through June 30, 2021. The SHARP II program ended June 30, 2021 and the final rate adjustment for this program became effective October 1, 2021. IIP – In November 2020, SJG filed a petition with the BPU, seeking authority to implement an IIP pursuant to which SJG would recover the costs associated with SJG's planned initial investment of approximately $742.5 million from 2021-2026 to, among other things, replace its at-risk plastic and coated steel mains, as well as excess flow valves on new service lines, and related services. This matter is pending before the BPU. EET - SJG has authorization to recover costs associated with its EEPs through the EET cost recovery mechanism. The EEP rate enables SJG to recover the costs of its EEP as authorized by the BPU. SJG’s EEP consists of a range of rebates and related offers, including, for example, various customer education and outreach initiatives, as well as an on-line customer dashboard, that are designed to encourage customers to conserve energy and to provide them with information on how to lower their gas bills. In October 2018, the BPU approved the continuation of SJG's existing EEPs with modifications, and to implement several new EEPs for a period of three years (the "EEP IV"), with a total budget of $81.3 million and a revenue increase of $3.5 million, effective November 1, 2018, which allow SJG to recover incremental operating and maintenance expenses and earn a return of, and return on, program investments over a seven-year amortization period. From 2019 through 2021, the following changes occurred related to the recovery of costs and the allowed return of, and on, prior investments associated with EET/EEPs: • January 2019 - The BPU approved a $1.6 million decrease in revenues, effective February 1, 2019. • January 2020 - The BPU approved a $1.3 million increase in revenues, effective February 1, 2020. • January 2021 - The BPU approved a $5.9 million increase in revenues, effective February 1, 2021. In addition, in September 2020, SJG filed a petition seeking authorization to implement new EEPs, commencing July 1, 2021 (the "EEP V"). SJG’s petition included a request to recover, in the first year, $6.3 million in revenues. In April 2021, the BPU approved SJG's continuation of several of SJG's existing EEPs with modifications. It also approved SJG's implementation of EEP V for a period of three years, with a total budget of $133.3 million and a revenue increase of $5.4 million, effective July 1, 2021. This approval allows SJG to recover incremental operating and maintenance expenses and earns a return of, and return on, program investments over a ten-year amortization period. SBC - The SBC allows SJG to recover costs related to several BPU-mandated programs. Within the SBC are the RAC, the CLEP and the USF and LL programs. The USF and LL programs require a separate annual regulatory filing while annual adjustments for the RAC and CLEP programs are the subject of our annual SBC filings discussed below. The RAC recovers environmental remediation costs of 12 former gas manufacturing plants (see Note 15). The BPU allows SJG to recover such costs over seven-year amortization periods, resulting in a regulatory asset for the costs that have been incurred but not yet recovered in rates (see Note 11). The CLEP recovers costs associated with SJG’s energy efficiency and renewable energy programs required under the NJCEP. From July 2018 through July 2021, the BPU approved annual NJCEP funding levels of $344.7 million for which SJG’s annual responsibility during the timeframe ranged from $12.7 million to $13.2 million. Regulatory filings related to the RAC and CLEP programs over the preceding three years were as follows: • 2018-2019 SBC filing - In March 2019, the BPU approved a $2.2 million decrease in revenues, with rates effective May 1, 2019. • 2019-2020 SBC filing - In March 2020, the BPU approved a $3.9 million increase in revenues, effective April 1, 2020. • 2020-2021 SBC filing - In April 2021, the BPU approved a $5.1 million increase in annual revenue, effective June 1, 2021. • 2021-2022 SBC filing - In July 2021, SJG filed its annual SBC petition, requesting a $0.9 million increase in annual revenues. This matter is pending BPU approval. The USF and LL are statewide programs which are funded from collections from customers of all New Jersey electric and gas utilities. From 2018-2021, the BPU approved statewide USF and LL annual budgets for all NJ gas utilities ranging from $45.6 million to $80.3 million, of which SJG’s annual responsibility during that timeframe was between $5.5 million and $9.6 million. Unbundling - This allows all natural gas consumers to select their natural gas commodity supplier. As of December 31, 2021, 19,793 of SJG's customers were purchasing their gas commodity from someone other than SJG. Customers choosing to purchase natural gas from providers other than the utility are charged for the cost of gas by the marketer. While customer choice can reduce utility revenues, it does not negatively affect SJG's net income or financial condition as the resulting decrease in utility revenues is offset by a corresponding decrease in gas costs. The BPU continues to allow for full recovery of prudently incurred natural gas costs through the BGSS. Unbundling did not change the fact that SJG still recovers cost of service, including certain deferred costs, through base rates. Pipeline Integrity Costs - SJG is permitted to defer and recover incremental costs incurred as a result of Pipeline Integrity Management regulations, which are aimed at enhancing public safety and reliability. The regulations require that utilities use a comprehensive analysis to assess, evaluate, repair and validate the integrity of certain transmission lines in the event of a leak or failure. SJG is authorized to defer future program costs, including related carrying costs, for recovery in the next base rate case proceeding, subject to review by the BPU. Tax Reform - In response to the implementation of Tax Reform, in March 2018, SJG filed a petition with the BPU for a change within base rates, a customer refund, and the introduction of a rider ("Rider H") to reflect the change in the corporate tax rate from 35% to 21%. The BPU subsequently approved an interim rate reduction, effective April 1, 2018, to reflect the change in the corporate tax rate under Tax Reform, within SJG's base rates. In September 2018, the BPU granted final approval of SJG's request, including: ◦ A final base rate adjustment to reflect an annual revenue reduction of approximately $25.9 million, effective April 1, 2018; ◦ A one-time customer refund was issued in October 2018 of approximately $13.8 million, including interest, for over collected tax during the period January 1, 2018 through September 30, 2018; and ◦ A customer refund of approximately $27.5 million to return "Unprotected" EDIT to customers through SJG's Rider H over a five-year period effective October 1, 2018. In May 2020, the BPU issued an Order resolving SJG’s 2019 Compliance Filing and 2019 Tax Act Rider petition, with a revised Rider H credit rate effective June 1, 2020. The terms of settlement include the following: • The “Unprotected” EDIT balance of approximately $44.7 million (adjusted from the previously approved level to reclassify certain EDIT from "Protected" to "Unprotected") will be refunded to customers over a 5 year period through the approved rider (which began October 1, 2018); • The net “Protected” EDIT regulatory liability of $149.4 million (regulatory liability of $181.0 million partially offset by a regulatory asset of $31.6 million) will be refunded to customers through a proposed base rate adjustment in SJG’s next base rate case. That next base rate case was the 2020 rate filing and the BPU approved a settlement under which amortization of the net “Protected” EDIT was used to reduce the test year revenue requirement over the remaining book lives of the related assets. In June 2020, in compliance with the September 2018 Order discussed above, SJG submitted its annual Rider H true up filing to modify SJG’s current Rider H credit rate for the period of October 1, 2020 through September 30, 2021. In September 2020, the BPU approved a rate adjustment to SJG’s Rider H credit rate to refund, from October 1, 2020 through September 30, 2021, approximately $14.9 million related to SJG’s "Unprotected" EDIT. Additionally, as part of the approved settlement in its base rate case, SJG will refund an additional $1.9 million associated with the accumulated balance of the amortization of the "Protected" EDIT recognized during the period January 1, 2018 through June 30, 2019. Effective October 1, 2020, this amount will be refunded to customers through the Rider H credit rate over its remaining three-year term. In June 2021, in compliance with the September 2018 Order discussed above, SJG submitted its annual Rider H true-up filing to modify SJG's current Rider H credit rate for the period of October 1, 2021 through September 30, 2022. In its filing, SJG proposed to return $11.6 million to its customers. This matter is pending before the BPU. ETG: Base Rate Case - In April 2019, ETG filed a petition with the BPU requesting a base rate revenue increase to recognize the infrastructure investments made to maintain the safety and reliability of its natural gas system. In November 2019, the BPU issued an Order that permitted ETG to increase base rate revenues by $34.0 million with new rates in effect November 15, 2019. The Order also provides for an after-tax rate of return of approximately 6.5%, with a return on equity of approximately 9.6% and a common equity component of approximately 51.5%. In December 2021, ETG filed a petition with the BPU requesting a base rate revenue increase, which was updated in February 2022 to a requested increase of $72.9 million, primarily to obtain a return on new capital investments made by ETG since the settlement of its last base rate case in 2019. This matter is pending before the BPU. Periodic Rate Mechanisms : Like SJG, ETG's tariff includes several primary rate mechanisms. The current effective rate mechanisms reflected in ETG's tariff, and regulatory actions regarding each for the preceding three years, are described below (filings and petitions described below are still pending, unless otherwise indicated). The approvals for the BGSS and the clauses under the SBC discussed below do not impact ETG's earnings. They represent changes in the cash requirements of ETG corresponding to cost changes and/or previous over/under recoveries from ratepayers associated with each respective mechanism. IIP - Consistent with approval of the ETG/ELK Acquisition, SJI was required to develop a plan, in concert with the BPU and the New Jersey Division of Rate Counsel, to address the replacement of ETG's aging infrastructure. In October 2018, ETG filed an IIP petition with the BPU pursuant to rules adopted by the BPU in December 2017 pertaining to utility infrastructure investments. The IIP petition sought authority to recover the costs associated with ETG's initial investment of approximately $518.0 million from 2019-2023 to, among other things, replace its cast-iron and low-pressure vintage main and related services. The IIP petition included a request for timely recovery of ETG's investment on a semi-annual basis through a separate rate mechanism. In June 2019, the BPU approved a $300.0 million IIP effective July 1, 2019. The Order authorized the recovery of costs associated with ETG’s investments of approximately $300.0 million between 2019-2024 to replace its cast-iron and bare steel vintage main and related services. The Order provides for annual recovery of ETG's investments through a separate rate mechanism. In April 2020, ETG submitted its annual filing, pursuant to the June 2019 BPU approval of the IIP. In July 2020, ETG submitted an updated filing, reflecting rider rates to increase annual revenues by $6.8 million to reflect the roll-in of $63.3 million of IIP investments for the period July 2019 through June 2020. The BPU issued an Order in September 2020 approving the updated IIP rates effective October 1, 2020. In April 2021, ETG submitted its annual filing, pursuant to the June 2019 BPU approval of the IIP. In July 2021, ETG submitted an updated filing, reflecting rider rates to increase annual revenues by $7.1 million to reflect the roll-in of $64.0 million of IIP investments for the period July 2020 through June 2021. The BPU issued an Order in September 2021 approving the updated IIP rates effective October 1, 2021. BGSS Clause - The BGSS for ETG is similar to that of SJG defined above. • March 2020 - The BPU approved ETG's annual BGSS filing in May 2019 to maintain its current BGSS-P rate. As ETG requested to maintain its current rate there was no corresponding increase or decrease in gas cost recoveries requested. This was approved on a provisional basis effective October 1, 2019, and final rates were approved, effective April 1, 2020, with no changes. • June 2020 - ETG submitted its annual BGSS filing. During discovery, ETG updated the rate for a revised request of a $21.1 million decrease in revenues. The BPU issued an Order in September 2020 approving the revised rate decrease on a provisional basis effective October 1, 2020, and final rates were approved, effective July 1, 2021, with no changes. • June 2021 - ETG submitted its annual BGSS filing. In August 2021, ETG updated the requested rate for a revised $11.3 million increase in revenues. The BPU issued an Order in November 2021 approving the revised rate increase on a provisional basis, effective December 1, 2021. In addition, as allowed under the BGSS clause, in November 2021, ETG issued a notice to the BPU of ETG's intent to self-implement a BGSS rate adjustment representing an additional 5% increase of the monthly bill of a typical residential customer, effective December 2021, for a total increase of $19.1 million in revenues. CIP - In April 2021, the BPU approved the implementation of ETG's CIP, which is similar to SJG's discussed above and further discussed below under "EEP." Each CIP year begins on July 1 and ends on June 30 of the subsequent year, with the first year effective July 1, 2021. The CIP replaces the WNC, which is discussed below. EEP - ETG's EEP is similar to SJG's discussed above. ETG has authorization from the BPU to offer its EEP through June 30, 2024 at a total budget of approximately $83.4 million, which allows ETG to recover incremental operating and maintenance expenses and earn a return of, and return on, program investments over a ten-year amortization period. From 2019 through 2021, the following changes occurred related to the recovery of costs and the allowed return on prior investments associated with EEPs: • January 2019 - ETG entered into a stipulation with Board Staff and the New Jersey Division of Rate Counsel extending its EEP through February 29, 2020 at a total budget of approximately $3.0 million. The BPU approved the stipulation in February 2019. • April 2019 - The BPU approved a revenue increase of $1.3 million associated with ETG’s annual EEP rate adjustment filing, effective May 1, 2019. • July 2019 - ETG filed its annual EEP rate adjustment petition, requesting a $1.0 million increase in revenues to continue recovering the costs of, and the allowed return on, investments associated with its EEP. In the first quarter of 2020, the final rate was approved by the BPU, effective April 1, 2020. The final rate reflected a $0.9 million increase in revenues. • In February 2020, the BPU approved ETG's stipulation with the BPU and the New Jersey Division of Rate Counsel extending its EEP through June 2020 under the previously approved budget and from July 2020 through December 2021 at a total budget of approximately $4.2 million. • In July 2020, ETG filed its annual EEP rate adjustment petition, requesting a $0.2 million decrease in revenues related to the recovery of costs of, and the allowed return on, investments associated with its EEPs. In June 2021, the BPU approved the stipulation to resolve ETG's annual EEP filing, effective July 1, 2021. The final rate reflected a $0.5 million decrease in revenues. • In September 2020, ETG filed for a new EEP program to expand its EEPs for three years and also proposed to establish a CIP, similar to SJG’s CIP, which eliminates the link between usage and margin and includes a weather component. In April 2021, the BPU approved the stipulation for ETG's new EEP program to expand its EEPs for three years effective July 1, 2021, authorizing a total budget of $83.4 million which would initially increase annual revenues by $2.8 million. This new EEP program replaces the one previously in effect. In April 2021, the BPU also approved the stipulation to establish a CIP effective July 1, 2021. • In July 2021, ETG filed its annual EEP rate adjustment petition for its legacy EEP programs, requesting a $1.6 million decrease in revenues related to the recovery of costs of, and the allowed return on, investments associated with its EEPs. This matter is pending BPU approval. WNC - The WNC rate allows ETG to implement surcharges or credits during the months of October through May to compensate for weather-related changes in customer usage from the previous winter period. • 2019-2020 WNC filing - In September 2019, the BPU approved a $7.8 million decrease in revenues to return a net revenue excess of $1.6 million primarily due to colder than normal weather, effective November 1, 2019. The BPU approved a slightly lower final rate effective April 1, 2020. • 2020-2021 WNC filing - In September 2020, the BPU approved a $7.1 million increase in revenues to an annual revenue of $5.5 million to recover a deficiency from warmer than normal weather, effective October 1, 2020. This rate was approved by the BPU as final on February 17, 2021. • 2021-2022 WNC filing - In September 2021, the BPU approved an annual revenue increase of $5.5 million to recover a deficiency balance associated with the period ending May 31, 2021 due to warmer than normal weather. This rate was approved by the BPU on a provisional basis effective October 1, 2021. The WNC calculation ended May 31, 2021 and was replaced by the CIP effective July 1, 2021 as further discussed above. SBC - Similar to SJG, the SBC allows ETG to recover costs related to several BPU-mandated programs, including the RAC, the CEP and the USF and LL programs. The RAC is similar to that of SJG defined above, recovering environmental remediation costs of former manufactured gas plants (see Note 15) and resulting in a regulatory asset for the costs that have been incurred but not yet recovered in rates (see Note 11). • May 2019 - The BPU approved ETG's annual RAC filing with the BPU, with a $6.9 million increase in RAC recoveries, effective June 1, 2019. • March 2020 -The BPU approved ETG's annual RAC rate adjustment petition, requesting a $6.0 million increase in revenues, effective April 1, 2020. • March 2021 - The BPU approved ETG's annual RAC rate adjustment petition, with a $3.2 million decrease in revenues, effective April 1, 2021. • November 2021 - The BPU approved ETG's annual RAC rate adjustment petition on a provisional basis, with a $7.9 million decrease in revenues, effective December 1, 2021. The CEP recovers costs associated with ETG’s energy efficiency and renewable energy programs required under the NJCEP. From July 2018 through June 2021, the BPU approved annual NJCEP funding levels of $344.7 million for which ETG's annual responsibility during the timeframe ranged from $10.6 million to $11.5 million. • 2019-2020 CEP filing - In September 2019, the BPU approved a $0.1 million decrease in revenues, effective November 1, 2019. • 2020-2021 CEP filing - In September 2020, the BPU approved a $3.2 million increase in revenues effective October 1, 2020. • 2021-2022 CEP filing - In September 2021, the BPU approved, on a provisional basis, a $0.2 million decrease in revenues effective October 1, 2021. The USF and LL are statewide programs through which funds are collected from customers of all New Jersey electric and gas utilities. Annually, the BPU approves a statewide budget for these programs, as noted within the SJG section above. From 2019-2021, ETG's annual responsibility was between $5.4 million and $9.0 million. ELK: As discussed in Note 1, in December 2019, the Company entered into an agreement to sell ELK to a third-party buyer. This transaction was approved by the MPSC on June 29, 2020. This transaction closed on July 31, 2020.

Regulatory Assets and Liabilities Disclosure [Abstract]
REGULATORY ASSETS & REGULATORY LIABILITIES	REGULATORY ASSETS & REGULATORY LIABILITIES:The discussion under Note 10 is integral to the following explanations of specific regulatory assets and liabilities. The Utilities' Regulatory Assets consisted of the following items (in thousands) : December 31, 2021 SJG ETG Total SJI Environmental Remediation Costs: Expended - Net $ 151,630 $ 13,972 $ 165,602 Liability for Future Expenditures 97,964 77,830 175,794 Deferred ARO Costs 47,784 33,872 81,656 Deferred Pension Costs - Unrecognized Prior Service Cost — 30,881 30,881 Deferred Pension and Other Postretirement Benefit Costs 47,504 813 48,317 Deferred Gas Costs - Net 38,234 — 38,234 CIP Receivable 17,776 2,955 20,731 SBC Receivable (excluding RAC) 7,519 — 7,519 Deferred Interest Rate Contracts 8,002 — 8,002 EET/EEP 20,632 5,199 25,831 AFUDC - Equity Related Deferrals 12,199 — 12,199 WNC — 4,269 4,269 Deferred COVID-19 Costs 7,687 10,225 17,912 Other Regulatory Assets 25,814 9,655 35,469 Total Regulatory Assets $ 482,745 $ 189,671 $ 672,416 December 31, 2020 SJG ETG Total SJI Environmental Remediation Costs: Expended - Net $ 157,340 $ 5,196 $ 162,536 Liability for Future Expenditures 101,243 91,837 193,080 Insurance Recovery Receivables — (6,807) (6,807) Deferred ARO Costs 42,365 25,453 67,818 Deferred Pension Costs - Unrecognized Prior Service Cost — 33,898 33,898 Deferred Pension and Other Postretirement Benefit Costs 77,426 8,466 85,892 Deferred Gas Costs - Net 19,178 — 19,178 CIP Receivable 21,013 — 21,013 SBC Receivable (excluding RAC) 3,453 — 3,453 Deferred Interest Rate Contracts 9,938 — 9,938 EET/EEP 18,725 3,062 21,787 AFUDC - Equity Related Deferrals 11,822 — 11,822 WNC — 7,444 7,444 Deferred COVID-19 Costs 4,737 5,818 10,555 Other Regulatory Assets 27,844 4,541 32,385 Total Regulatory Assets $ 495,084 $ 178,908 $ 673,992 Except where noted below, all regulatory assets are or are expected to be recovered through utility rate charges, as detailed in the following discussion. The Utilities are currently permitted to recover interest on Environmental Remediation Costs, SBC Receivable, EET/EEP and Pipeline Integrity Costs, while the other assets are being recovered without a return on investment. ENVIRONMENTAL REMEDIATION COSTS - SJG and ETG have regulatory assets associated with environmental costs related to the cleanup of environmental sites as discussed in Note 15. "Environmental Remediation Cost: Liability for Future Expenditures," relates to estimated future expenditures required to complete the remediation of these sites. SJG and ETG recorded this estimated amount as a regulatory asset with the corresponding current and noncurrent liabilities on the consolidated balance sheets under the captions "Current Liabilities" (SJI and SJG) and "Deferred Credits and Other Noncurrent Liabilities" (SJI) and "Regulatory and Other Noncurrent Liabilities" (SJG). These costs meet the deferral requirements of ASC 980, as the BPU allows SJG and ETG to recover such expenditures through the RAC mechanism. "Environmental Remediation Cost: Expended - Net," represents what has been spent to clean up the sites, less recoveries through the RAC and insurance carriers. The BPU allows SJG and ETG to recover the deferred costs not recovered from insurance carriers through their RAC mechanisms over seven-year periods after the costs are incurred. "Insurance Recovery Receivables" represents the balance of an insurance settlement executed in the fourth quarter of 2019 with a third party. This settlement was to be received in installments, and was returned to ETG's customers through the RAC. Of the original total of $20.4 million, $13.6 million was received by ETG in 2020. The remaining $6.8 million was not collected in 2021 per the settlement as the insurance company was placed in liquidation. The Company has fully reserved for this receivable within "Environmental Remediation Cost: Expended - Net," as the probability of recovery is remote. DEFERRED ARO COSTS - The Utilities record AROs primarily related to the legal obligation to cut and cap gas distribution pipelines when ta king those pipelines out of service. Deferred ARO costs represent the period to period passage of time (accretion) and depreciation of the underlying ARO asset. The Deferred ARO Costs regulatory asset increased year over year due to both accretion and depreciation. There is no impact on earnings as a result of these changes. DEFERRED PENSION COSTS - UNRECOGNIZED PRIOR SERVICE COST - The BPU approved ETG to recover costs related to ETG's unrecognized prior service cost and actuarial gains/losses for pension and postretirement benefits. This ETG deferred asset is being amortized over 15.0 years for pension and over 9.2 years f or postretirement benefits. DEFERRED PENSION AND OTHER POSTRETIREMENT BENEFIT COSTS - The BPU authorized SJG and ETG to recover costs related to postretirement benefits under the accrual method of accounting consistent with GAAP. SJI's regulatory asset represents the recognition of the underfunded positions of SJI's and ETG's pension and other postretirement benefit plans. Subsequent adjustments to this balance occur annually to reflect changes in the funded positions of these benefit plans caused by changes in actual plan experience as well as assumptions of future experience (see Note 12). DEFERRED GAS COSTS - NET - Over/under collections of gas costs are monitored through SJG's and ETG's BGSS clause. Net undercollected gas costs are classified as a regulatory asset and net overcollected gas costs are classified as a regulatory liability (see Note 10). Realized and unrealized gains and losses on derivative contracts used to hedge natural gas purchases are als o included in the BGSS, subject to BPU approval (see Note 16). Included in SJG's balance as of both December 31, 2021 and 2020 is $21.3 million and $22.9 million, respectively, of costs related to a previous pricing dispute on a long-term gas supply contract. As of June 1, 2021, SJG has begun to recover these costs from its customers through the BGSS clause. SJG’s deferred gas costs-net are in an under-recovered position, resulting in a regulatory asset as of December 31, 2021. The BGSS regulatory assets of SJG increased year over year primarily due to the actual gas commodity costs exceeding the recoveries from customers and overall higher commodity costs due to higher market prices, partially offset by changes in valuations of hedged natural gas positions from prior periods. ETG's deferred gas costs-net are in an over-recovered position, resulting in a regulatory liability as of December 31, 2021, see the Regulatory Liabilities table below. CIP RECEIVABLE - The CIP tracking mechanism at the Utilities adjusts earnings when the actual usage per customer experienced during the period varies from an established baseline usage per customer . For SJG, actual usage per customer was more than the established baseline during 2021, resulting in a reduction of the regulatory asset at December 31, 2021 as compared to 2020. This is primarily the result of colder than normal weather experienced in the region in 2021 compared to 2020. For ETG, actual usage per customer was less than the established baseline during 2021, resulting in the establishment of the regulatory asset during 2021 as CIP was effective for ETG July 1, 2021. SBC RECEIVABLE - This regulatory asset primarily represents the deferred expenses incurred under SBC programs, which include the CEP/CLEP, USF and LL mechanisms (see Note 10). Under recoveries are presented as a regulatory asset and over recoveries are presented as a regulatory liability. The increase in SJG's SBC receivable is primarily due to CLEP expenditures in excess of recoveries during the period. ETG's SBC mechanisms are in a regulatory liability position and presented within other regulatory liabilities. DEFERRED INTEREST RATE CONTRACTS - These amounts represent the unrealized gains or losses of interest rate derivatives as discussed further in Note 16. EET/EEP - The EET/EEP Regulatory Assets of SJG and ETG increased year over year primarily due to expenditures in excess of recoveries as well as the investments in the new EEPs which were effective July 1, 2021 (see Note 10). AFUDC EQUITY RELATED DEFERRALS - This regulatory asset represents the future revenue to recover the future income taxes related to the deferred tax liability for the equity component of AFUDC. The deferred amount is being amortized over the life of the associated utility plant. WNC - The tariffs for ETG include a weather normalization clause that reduces customer bills when weather is colder than normal and increases customer bills when weather is warmer than normal. The overall change in ETG's weather normalization from 2020 to 2021 was due to colder than normal weather during the winter months. The WNC deferral ended May 31, 2021 and was replaced by the CIP effective July 1, 2021. Amounts recorded as a regulatory asset will continue to be collected from customers until the WNC balance is fully recovered. DEFERRED COVID-19 COSTS - On July 2, 2020, the BPU issued an Order authorizing New Jersey's regulated utilities to create a COVID-19-related regulatory asset by deferring on their books and records the prudently incurred incremental costs related to COVID-19 beginning on March 9, 2020 and continuing through September 30, 2021, or 60 days after the termination of the public health emergency, whichever is later. On September 14, 2021, the BPU extended this period to December 31, 2022. The Company is required to file quarterly reports with the BPU, along with a petition of recovery of such incremental costs with the BPU by December 31, 2022 or within 60 days of the close of the tracking period, whichever is later. The deferred balance is principally related to expected credit losses from uncollectibles as a result of the COVID-19 pandemic, specifically related to changes in payment patterns observed to date and consideration of macroeconomic factors. We have deemed these costs to be probable of recovery. OTHER REGULATORY ASSETS - Some of the assets included in Other Regulatory Assets are currently being recovered from ratepayers as approved by the BPU. Management believes the remaining deferred costs are probable of recovery from ratepayers through future utility rates. The Utilities' Regulatory Liabilities consisted of the following items (in thousands): December 31, 2021 SJG ETG Total SJI Excess Plant Removal Costs $ 12,125 $ 33,988 $ 46,113 Excess Deferred Taxes 206,902 111,003 317,905 Deferred Gas Costs - Net — 28,842 28,842 Other Regulatory Liabilities 3,384 2,707 6,091 Total Regulatory Liabilities $ 222,411 $ 176,540 $ 398,951 December 31, 2020 SJG ETG Total SJI Excess Plant Removal Costs $ 12,666 $ 37,953 $ 50,619 Excess Deferred Taxes 232,694 113,888 346,582 Deferred Gas Costs - Net — 22,291 22,291 Other Regulatory Liabilities — 1,085 1,085 Total Regulatory Liabilities $ 245,360 $ 175,217 $ 420,577 EXCESS PLANT REMOVAL COSTS - The Utilities accrue and collect for cost of removal of utility property. This regulatory liability represents customer collections in excess of actual expenditures, which will be returned to customers as a reduction to depreciation expense. The Excess Plant Removal Costs Liability decreased year over year primarily due to the actual removal costs exceeding the collections in 2021. EXCESS DEFERRED TAXES - This liability is recognized as a result of Tax Reform enacted into law on December 22, 2017. The decrease in this regulatory liability year over year is related to excess tax amounts returned to customers through customer billings. See Note 10. DEFERRED GAS COSTS - NET - Over/under collections of gas costs are monitored through ETG's BGSS mechanism. Net under collected gas costs are classified as a regulatory asset and net over-collected gas costs are classified as a regulatory liability. Derivative contracts used to hedge natural gas purchases are also included in the BGSS, su bject to BPU approval, along with amounts to be returned to customers under the AMA as discussed in Note 1. The increase year over year is primarily driven by the change in the value of the energy-related derivative contracts. OTHER REGULATORY LIABILITIES - This liability primarily represents recoveries in excess of expenditures for the SBC programs, which include the CEP/CLEP, USF and LL mechanisms (see Note 10).

Retirement Benefits [Abstract]
PENSION AND OTHER POSTRETIREMENT BENEFITS	PENSION AND OTHER POSTRETIREMENT BENEFITS:SJI ans ETG sponsor several trusteed, qualified defined benefit pension plans and other postretirement benefit plans. Employees of SJG participate in the defined benefit pension plans and other postretirement benefit plans of SJI. SJI's qualified defined benefit pension plan was closed beginning in 2003. ETG's defined benefit pension plan was closed to new employees beginning in 2018. SJI's and ETG's plans are funded in accordance with the requirements of the ERISA. In addition, non-union employees are eligible to participate in the defined contribution plan. Approximately 30% and 28% of SJI's and SJG's current, full-time, regular employees, respectively, will be entitled to annuity payments upon retirement. The Company also provides a non-qualified benefit and defined contribution pension plan for a selected group of the Company's management and highly compensated employees. Benefits under these non-qualified pension plans, including the SERP discussed below, are funded on a cash basis. In addition, SJI and ETG provide health care and life insurance benefits for eligible retired employees through postretirement benefit plans. Net periodic benefit cost related to the SJI employee and officer pension and other postretirement benefit plans consisted of the following components (in thousands): SJI (includes SJG and all other consolidated subsidiaries): Pension Benefits 2021 2020 2019 Service Cost $ 5,887 $ 5,871 $ 5,583 Interest Cost 13,028 15,017 17,294 Expected Return on Plan Assets (23,762) (21,929) (20,195) Amortization: Prior Service Cost 98 105 105 Actuarial Loss 12,932 10,845 9,550 Net Periodic Benefit Cost 8,183 9,909 12,337 Settlement, Curtailment and Special Termination Costs 44 781 955 Capitalized Benefit Costs (1,551) (1,969) (2,008) Deferred Benefit Costs (1,168) (1,591) (2,411) Total Net Periodic Benefit Expense $ 5,508 $ 7,130 $ 8,873 SJI (includes SJG and all other consolidated subsidiaries): Other Postretirement Benefits 2021 2020 2019 Service Cost $ 814 $ 681 $ 533 Interest Cost 1,920 2,367 2,884 Expected Return on Plan Assets (5,741) (5,381) (4,571) Amortization: Prior Service Credits (624) (624) (561) Actuarial Loss 1,118 853 1,163 Net Periodic Benefit Credit (2,513) (2,104) (552) Capitalized Benefit Costs (225) (209) (201) Deferred Benefit Costs 1,164 935 357 Total Net Periodic Benefit Income $ (1,574) $ (1,378) $ (396) Net periodic benefit cost related to the SJG employee and officer pension and other postretirement benefit plans consisted of the following components (in thousands): SJG: Pension Benefits 2021 2020 2019 Service Cost $ 3,778 $ 3,797 $ 3,621 Interest Cost 8,481 9,695 11,067 Expected Return on Plan Assets (13,403) (11,903) (11,028) Amortization: Prior Service Cost 88 95 95 Actuarial Loss 11,569 9,364 8,224 Net Periodic Benefit Cost 10,513 11,048 11,979 Capitalized Benefit Costs (1,551) (1,395) (1,437) Affiliate SERP Allocations (4,728) (3,938) (3,541) Deferred Benefit Costs (1,168) (1,591) (2,411) Total Net Periodic Benefit Expense $ 3,066 $ 4,124 $ 4,590 SJG: Other Postretirement Benefits 2021 2020 2019 Service Cost $ 480 $ 396 $ 343 Interest Cost 1,181 1,463 1,863 Expected Return on Plan Assets (4,041) (3,860) (3,220) Amortization: Prior Service Credits (502) (502) (474) Actuarial Loss 884 672 1,042 Net Periodic Benefit Credits (1,998) (1,831) (446) Capitalized Benefit Costs (225) (166) (155) Deferred Benefit Costs 1,164 935 357 Total Net Periodic Benefit Income $ (1,059) $ (1,062) $ (244) Settlement, Curtailment and Special Termination Costs reflected in the tables above in 2021 were not material; in 2020 relate to a settlement of certain participants' benefits under ETG's pension plan; and in 2019 relate to an ERIP. Capitalized benefit costs reflected in the tables above relate to the Utilities' construction programs. Only the service cost component of net benefit cost is eligible for capitalization. Companies with publicly traded equity securities that sponsor a postretirement benefit plan are required to fully recognize, as an asset or liability, the overfunded or underfunded status of its benefit plans and recognize changes in the funded status in the year in which the changes occur. Changes in funded status are generally reported in AOCL; however, since the Utilities recover all prudently incurred pension and postretirement benefit costs from its ratepayers, a significant portion of the charges resulting from the recording of additional liabilities under this requirement are reported as regulatory assets (see Note 11).

Consist of: Net Actuarial Loss $ 35,487 $ 47,437 $ — $ — The PBO and ABO of SJI's qualified employee pension plans were $371.9 million and $355.3 million, respectively, as of December 31, 2021; and $388.3 million and $370.2 million, respectively, as of December 31, 2020. The ABO of these plans exceeded the value of the plan assets as seen in the SJI table above under "Change in Plan Assets." The PBO and ABO for SJI's non-funded SERP were $89.7 million and $88.4 million, respectively, as of December 31, 2021; and $93.6 million and $90.6 million, respectively, as of December 31, 2020. SJI's SERP obligation, along with the obligations under ETG's pension and other postretirement benefit plans, are reflected in the tables above. The PBO and ABO of SJG's qualified employee pension plans were $209.6 million and $201.4 million, respectively, as of December 31, 2021; and $218.4 million and $207.8 million, respectively, as of December 31, 2020. The ABO of these plans exceeded the value of the plan assets as seen in the SJG table above under "Change in Plan Assets." The PBO and ABO for SJG's non-funded SERP were $89.7 million and $88.4 million, respectively, as of December 31, 2021; and $93.2 million and $90.2 million, respectively, as of December 31, 2020. SJG's SERP obligation is reflected in the tables above. Actuarial gains incurred in 2021 are primarily a result of an increase in the discount rate assumptions used to estimate the benefit obligations as of December 31, 2021 compared to the prior year. Actuarial losses incurred in 2020 are primarily a result of a decrease in the discount rate assumptions used to estimate the benefit obligations as of December 31, 2020 compared to the prior year. The weighted-average assumptions used to determine benefit obligations for SJI and SJG at December 31 were: Pension Benefits Other Postretirement Benefits 2021 2020 2021 2020 Discount Rate 3.02 % 2.73 % 2.99 % 2.61 % Rate of Compensation Increase 3.00 % 3.00 % 3.00 % 3.00 % The weighted-average assumptions used to determine net periodic benefit cost (credit) for SJI and SJG for the years ended December 31 were: Pension Benefits Other Postretirement Benefits 2021 2020 2019 2021 2020 2019 Discount Rate 2.73 % 3.49 % 4.39 % 2.61 % 3.43 % 4.31 % Expected Long-Term Return on Plan Assets 7.25 % 7.25 % 7.25 % 6.75 % 6.75 % 6.75 % Rate of Compensation Increase 3.00 % 3.00 % 3.50 % 3.00 % 3.00 % 3.50 % The SOA updates the mortality projection on an annual basis. The Company utilizes the most current projection tables available. The obligations as of December 31, 2021, 2020 and 2019, disclosed herein, reflect the use of the updated projection tables applicable to those years. The discount rates used to determine the benefit obligations at each year end, which are used to determine the net periodic benefit cost for the subsequent year, were based on a portfolio model of high-quality investments with maturities that match the expected benefit payments under our pension and other postretirement benefit plans. The expected long-term return on plan assets (“return”) has been determined by applying long-term capital market projections provided by our pension plan Trustee to the asset allocation guidelines, as defined in SJI's and SJG's investment policy, to arrive at a weighted average return. For certain other equity securities held by an investment manager outside of the control of the Trustee, the return has been determined based on historic performance in combination with long-term expectations. The return for the other postretirement benefits plan is determined in the same manner as discussed above; however, the expected return is reduced based on the taxable nature of the underlying trusts. PLAN ASSETS - SJI's and SJG's overall investment strategy for pension plan assets is to achieve a diversification by asset class, style of manager, and sector and industry limits to achieve investment results that match the actuarially assumed rate of return, while preserving the inflation adjusted value of the plans. The target allocations for pension plan assets are 40-70 percent equity securities, 0-10 percent cash, 25-60 percent fixed income investments, and 0-10 percent to all other types of investments. Equity securities include investments in large-cap, mid-cap and small-cap companies within mutual funds. Fixed income securities include group annuity contracts for pension payments, and hedge funds. Other types of investments include investments in private equity funds and real estate funds that follow several different strategies. The strategy recognizes that risk and volatility are present to some degree with all types of investments. SJI and SJG seek to avoid high levels of risk at the total fund level through diversification by asset class, style of manager, and sector and industry limits. Specifically prohibited investments include, but are not limited to, venture capital, margin trading, commodities and securities of companies with less than $250.0 million capitalization (except in the small-cap portion of the fund where capitalization levels as low as $50.0 million are permissible). These restrictions are only applicable to individual investment managers with separately managed portfolios and do not apply to mutual funds or commingled trusts. SJI evaluated its pension and other postretirement benefit plans' asset portfolios for the existence of significant concentrations of credit risk as of December 31, 2021. Types of concentrations that were evaluated include, but are not limited to, investment concentrations in a single entity, type of industry, foreign country, and individual fund. As of December 31, 2021, there were no significant concentrations (defined as greater than 10 percent of plan assets) of risk in SJI's pension and other postretirement benefit plan assets. GAAP establishes a hierarchy that prioritizes fair value measurements based on the types of inputs used for the various valuation techniques. This hierarchy groups assets into three distinct levels, as fully described in Note 17, which will serve as the basis for presentation throughout the remainder of this Note. The fair values of SJI's and SJG's pension plan assets at December 31, 2021 and 2020 by asset category are as follows (in thousands): SJI (includes SJG and all other consolidated subsidiaries): Asset Category Total Level 1 Level 2 Level 3 As of December 31, 2021 Cash / Cash Equivalents: Cash $ 1,299 $ 1,299 $ — $ — STIF-Type Instrument (a) 6,525 6,525 — — Equity securities: U.S. Large-Cap (b) 100,095 100,095 — — U.S. Mid-Cap (b) 14,730 14,730 — — U.S. Small-Cap (b) 13,639 13,639 — — International (b) 83,831 83,831 — — Fixed Income: Core Plus Fixed Income (c) 49,510 24,363 25,147 — Short Term Fixed (c) 27,039 27,039 — — Long Term Fixed (c) 41,875 41,875 — — Subtotal Fair Value $ 338,543 $ 313,396 $ 25,147 $ — Measured at net asset value practical expedient: Private Equity Fund (d) $ 13,055 Subtotal measured at net asset value practical expedient $ 13,055 Total Fair Value $ 351,598 Asset Category Total Level 1 Level 2 Level 3 As of December 31, 2020 Cash / Cash Equivalents: Cash $ 881 $ 881 $ — $ — STIF-Type Instrument (a) 5,779 5,779 — — Equity securities: U.S. Large-Cap (b) 100,322 100,322 — — U.S. Mid-Cap (b) 17,774 17,774 — — U.S. Small-Cap (b) 14,938 14,938 — — International (b) 86,085 86,085 — — Fixed Income: Core Plus Fixed Income (c) 54,066 27,296 26,770 — Long Term Fixed (c) 41,194 41,194 — — Subtotal Fair Value $ 321,039 $ 294,269 $ 26,770 $ — Measured at net asset value practical expedient: Private Equity Fund (d) $ 9,948 Subtotal measured at net asset value practical expedient $ 9,948 Total Fair Value $ 330,987 SJG: Asset Category Total Level 1 Level 2 Level 3 As of December 31, 2021: Cash / Cash Equivalents: Cash $ 213 $ 213 $ — $ — STIF-Type Instrument (a) 4,976 4,976 — — Equity securities: U.S. Large-Cap (b) 54,651 54,651 — — U.S. Mid-Cap (b) 7,632 7,632 — — U.S. Small-Cap (b) 7,580 7,580 — — International (b) 45,634 45,634 — — Fixed Income: Core Plus Fixed Income (c) 27,592 13,578 14,014 — Short Term Fixed (c) 14,931 14,931 — — Long Term Fixed (c) 23,396 23,396 — — Subtotal Fair Value $ 186,605 $ 172,591 $ 14,014 $ — Measured at net asset value practical expedient: Private Equity Fund (d) $ 10,335 Subtotal measured at net asset value practical expedient $ 10,335 Total Fair Value $ 196,940 Asset Category Total Level 1 Level 2 Level 3 As of December 31, 2020: Cash / Cash Equivalents: Cash $ 303 $ 303 $ — $ — STIF-Type Instrument (a) 3,380 3,380 — — Equity securities: U.S. Large-Cap (b) 52,346 52,346 — — U.S. Mid-Cap (b) 8,138 8,138 — — U.S. Small-Cap (b) 8,249 8,249 — — International (b) 44,120 44,120 — — Fixed Income: Core Plus Fixed Income (c) 32,571 16,450 16,121 — Long Term Fixed (c) 24,895 24,895 — — Subtotal Fair Value $ 174,002 $ 157,881 $ 16,121 $ — Measured at net asset value practical expedient: Private Equity Fund (d) $ 7,938 Subtotal measured at net asset value practical expedient $ 7,938 Total Fair Value $ 181,940 (a) This category represents short-term investment funds held for the purpose of funding disbursement payment arrangements. Underlying assets are valued based on quoted prices in active markets. These funds are classified as Level 1 investments. (b) This category of equity investments represents a managed portfolio of common stock investments among several sectors. These common stocks are actively traded on exchanges and price quotes for these shares are readily available. These common stocks are classified as Level 1 investments. (c) This category represents investments using a value-oriented fixed income strategy that invests primarily in a diversified mix of U.S. dollar-denominated investment-grade fixed income securities, with a predominant focus on investment-grade securities across all market sectors and maturities, as well as other alternatives such as high-yield bonds, emerging markets debt, and non-dollar bonds. Those values that can be obtained from quoted prices in active markets are classified as Level 1 investments. For those values where quoted prices are not in active markets, they are based on models using observable market information, and as such are classified as Level 2 investments. (d) This category represents a limited partnership which includes several investments in U.S. leveraged buyout, venture capital, and special situation funds. Fund valuations are reported on a 90 to 120 day lag and, therefore, the value reported herein represents the market value as of June or September 30, 2021 and 2020, respectively, with cash flow changes through December applied. The fund’s investments are stated at fair value, which is generally based on the valuations provided by the general partners or managers of such investments.

SJI and SJG have implemented this diversification strategy with a mix of mutual funds and Company-owned life insurance policies. The target allocations for post-retirement benefit plan assets are 55-75 percent equity securities, 0-10 percent cash, 25-45 percent fixed income investments and 0-10 percent to all other types of investments. Equity securities include investments in large-cap, mid-cap and small-cap companies within mutual funds. The insurance policies are backed by a series of commingled trust investments held by the insurance carrier. The fair values of SJI's and SJG's other postretirement benefit plan assets at December 31, 2021 and 2020 by asset category are as follows (in thousands): SJI (includes SJG and all other consolidated subsidiaries): Asset Category Total Level 1 Level 2 Level 3 As of December 31, 2021: Cash / Cash Equivalents: Cash $ 292 $ 292 $ — $ — STIF-Type Instrument (d) 2,780 2,780 — — Equity Securities: U.S. Large-Cap (a) 21,012 21,012 — — U.S. Mid-Cap (a) 4,292 4,292 — — U.S. Small-Cap (a) 7,380 7,380 — — U.S. International (a) 21,079 21,079 — — Fixed Income: Core Plus Fixed Income (c) 14,958 7,243 7,715 — Mutual Funds - Bonds (a) 12,724 12,724 — — Subtotal Fair Value $ 84,517 $ 76,802 $ 7,715 $ — Measured at net asset value practical expedient: Company Owned Life Insurance (b) $ 18,453 Subtotal measured at net asset value practical expedient $ 18,453 Total Fair Value $ 102,970 SJI (includes SJG and all other consolidated subsidiaries): Asset Category Total Level 1 Level 2 Level 3 As of December 31, 2020: Cash $ 2,334 $ 2,334 $ — $ — Equity Securities: U.S. Large-Cap (a) 18,839 18,839 — — U.S. Mid-Cap (a) 4,379 4,379 — — U.S. Small-Cap (a) 3,361 3,361 — U.S. International (a) 20,369 20,369 — Fixed Income: Core Plus Fixed Income (c) 6,431 — 6,431 — Mutual Funds - Bonds (a) 14,881 14,881 0 0 Subtotal Fair Value $ 70,594 $ 64,163 $ 6,431 $ — Measured at net asset value practical expedient: Company Owned Life Insurance (b) $ 17,276 Subtotal measured at net asset value practical expedient $ 17,276 Total Fair Value $ 87,870 SJG: Asset Category Total Level 1 Level 2 Level 3 As of December 31, 2021 Cash / Cash Equivalents: Cash $ 170 $ 170 $ — $ — STIF-Type Instrument (d) 2,616 2,616 0 0 Equity Securities: U.S. Large-Cap (a) 16,101 16,101 — — U.S. Mid-Cap (a) 2,652 2,652 — — U.S. Small-Cap (a) 2,115 2,115 — — U.S. International (a) 13,392 13,392 — — Fixed Income: Core Plus Fixed Income (c) 10,273 5,055 5,218 — Mutual Funds - Bonds (a) 8,603 8,603 — — Subtotal Fair Value $ 55,922 $ 50,704 $ 5,218 $ — Measured at net asset value practical expedient: Company Owned Life Insurance (b) $17,400 Subtotal measured at net asset value practical expedient $17,400 Total Fair Value $ 73,322 SJG: Asset Category Total Level 1 Level 2 Level 3 As of December 31, 2020 Cash $ 2,083 $ 2,083 $ 0 $ 0 Equity Securities: U.S. Large-Cap (a) 10,764 10,764 — — U.S. Mid-Cap (a) 2,591 2,591 — — U.S. Small-Cap (a) 2,200 2,200 — — U.S. International (a) 12,889 12,889 — — Fixed Income: Core Plus Fixed Income (c) 4,741 — 4,741 — Mutual Funds - Bonds (a) 10,392 10,392 — — Subtotal Fair Value $ 45,660 $ 40,919 $ 4,741 $ — Measured at net asset value practical expedient: Company Owned Life Insurance (b) $ 16,209 Subtotal measured at net asset value practical expedient $ 16,209 Total Fair Value $ 61,869 (a) This category represents a managed portfolio of common stock investments among several sectors.

FUTURE BENEFIT PAYMENTS - The following benefit payments, which reflect expected future service, as appropriate, are expected to be paid during the following years (in thousands): SJI (includes SJG and all other consolidated subsidiaries): Pension Benefits Other Postretirement Benefits 2022 $ 22,834 $ 5,451 2023 $ 23,550 $ 5,271 2024 $ 23,795 $ 4,932 2025 $ 24,008 $ 4,696 2026 $ 24,618 $ 4,448 2027 - 2031 $ 130,850 $ 18,642 SJG: Pension Benefits Other Postretirement Benefits 2022 $ 14,143 $ 3,591 2023 $ 14,658 $ 3,500 2024 $ 15,022 $ 3,285 2025 $ 15,398 $ 3,100 2026 $ 15,792 $ 2,926 2027 - 2031 $ 86,896 $ 11,931 CONTRIBUTIONS - SJI and SJG made $5.4 million and $5.0 million contributions to its employee pension and OPEB plans in 2021, respectively. SJI and SJG did not make contributions to its employee pension or OPEB plans in 2020 or 2019. Payments related to the unfunded SERP plan for SJI and SJG in 2021, 2020 and 2019 were $3.9 million, $3.9 million and $4.1 million, respectively. SERP payments for SJI and SJG are expected to approximate $3.9 million in 2022. DEFINED CONTRIBUTION PLAN - SJI, SJG and ETG offer a Savings Plan to eligible employees. For employees eligible for participation in the defined benefit pension plans, SJI and SJG match 50% of participants' contributions to the Savings Plan up to 6% of base compensation.

LINES OF CREDIT & SHORT-TERM BORROWINGS	LINES OF CREDIT & SHORT-TERM BORROWINGS: Credit facilities and available liquidity as of December 31, 2021 were as follows (in thousands): Company Total Facility Usage Available Liquidity Expiration Date SJI: SJI Syndicated Revolving Credit Facility $ 500,000 $ 152,800 (A) $ 347,200 September 2026 SJG: Commercial Paper Program/Revolving Credit Facility 250,000 109,900 (B) 140,100 September 2026 ETG: ETG Revolving Credit Facility 250,000 84,000 (C) 166,000 September 2026 Total $ 1,000,000 $ 346,700 $ 653,300 (A) Includes letters of credit outstanding in the amount of $9.8 million, which is used to enable SJE to market retail electricity as well as for various construction and operating activities. (B) Includes letters of credit outstanding in the amount of $1.9 million, which supports the remediation of environmental conditions at certain locations in SJG's service territory. (C) Includes letters of credit outstanding in the amount of $1.0 million, which supports ETG's construction activity. For SJI and SJG, the amount of usage shown in the table above, less the letters of credit noted in (A)-(C) for SJI and (B) for SJG above, equals the amounts recorded as Notes Payable on the respective consolidated balance sheets as of December 31, 2021. During the first quarter of 2021, SJI paid off its $150.0 million term loan agreement at maturity. On September 1, 2021, SJI, SJG and ETG (collectively, the "Borrowers") entered into an unsecured, five-year master revolving credit facility (the "Credit Facility") with a syndicate of banks, which expires on September 1, 2026, unless earlier terminated or extended in accordance with its terms. The Credit Facility provides for maximum borrowings in a total aggregate amount of $1.0 billion, including the issuance of swingline loans (in an amount not to exceed an aggregate of $100.0 million) and letters of credit (in an amount not to exceed an aggregate of $350.0 million, of which $50.0 million has been initially committed by various lenders), each at the applicable interest rates specified in the Credit Facility. The Borrowers each have access to a portion of the facility (a “Sublimit”) under which it can borrow, with the Sublimits of SJI, SJG and ETG initially being $500.0 million, $250.0 million and $250.0 million, respectively. The Sublimits may be changed from time to time at the request of the Borrowers, but with maximum and minimum Sublimits, which are subject to change upon certain events, including if the amount of available credit is increased. Borrowings under the Credit Facility are at market rates. Subject to certain conditions set forth in the Credit Facility, the Borrowers may increase the amount of the borrowings available under the Credit Facility by up to a maximum aggregate amount of $250.0 million (for a total facility of up to $1.25 billion), although no lender is obligated to increase its commitment. The Credit Facility contains customary representations, warranties and covenants, including a financial covenant limiting the ratio of Indebtedness of each Borrower and its subsidiaries on a consolidated basis to Consolidated Total Capitalization of each Borrower of not more than 0.70 to 1 (as such terms are defined in the Credit Facility). SJI, SJG and ETG were all in compliance with these covenants as of December 31, 2021. In connection with entry into the Credit Facility, the following revolving credit facilities were terminated effective September 1, 2021: (a) SJI's credit agreement, dated as of August 7, 2017, which provided for a revolving credit facility of up to $500.0 million; (b) SJG's credit agreement, dated as of August 14, 2017, which provided for a revolving credit facility of up to $200.0 million; and (c) ETG's credit agreement, dated as of June 29, 2018, which provided for a revolving credit facility of up to $200.0 million. SJG has a commercial paper program under which it may issue short-term, unsecured promissory notes to qualified investors up to a maximum aggregate amount outstanding at any time of $250.0 million. The notes have fixed maturities which may vary by note, but cannot exceed 270 days from the date of issue. Proceeds from the notes are used for general corporate purposes. SJG's commercial paper program is backstopped by its Sublimit allocation of the SJI Credit Facility of $250.0 million. The principal amount of borrowings outstanding under the commercial paper program and the Sublimit allocation credit facility cannot exceed an aggregate of $250.0 million. Although there can be no assurance, management believes that actions presently being taken to pay off or refinance the short-term debt and borrowings that are due within the next year will be successful, as the Company has been successful in refinancing debt in the past. No adjustments have been made to the financial statements to account for this uncertainty. The weighted average interest rate on these borrowings, which changes daily, were as follows: December 31, 2021 December 31, 2020 December 31, 2019 Weighted average interest rate on borrowings: SJI (inclusive of all subsidiaries' facilities) 1.05 % 1.35 % 2.67 % SJG 0.34 % 0.23 % 1.99 % Average borrowings and maximum amounts outstanding on these facilities for the years ended December 31 were as follows (in thousands): 2021 2020 Average borrowings outstanding, not including letters of credit: SJI (inclusive of all subsidiaries' facilities) $ 190,000 $ 472,900 SJG $ 40,900 $ 116,600 Maximum amounts outstanding, not including letters of credit: SJI (inclusive of all subsidiaries' facilities) $ 452,900 $ 872,200 SJG $ 123,000 $ 187,000

Commitments and Contingencies Disclosure [Abstract]
COMMITMENTS AND CONTINGENCIES	COMMITMENTS AND CONTINGENCIES:GAS SUPPLY CONTRACTS - In the normal course of business, SJG, SJRG and ETG have entered into long-term contracts for natural gas supplies, firm transportation and gas storage service. The transportation and storage service agreements with interstate pipeline suppliers were made under FERC-approved tariffs. SJG's and ETG's cumulative obligation for gas supply-related demand charges and reservation fees paid to suppliers for these services averages approximately $6.8 million and $5.5 million per month, respectively, and is recovered on a current basis through the BGSS. SJRG's cumulative obligation for demand charges and reservation fees paid to suppliers for these services averages approximately $0.8 million per month. SJRG has also committed to purchase 526,400 dts/d of natural gas, from various suppliers, for terms ranging from five ETG has an AMA with SJRG for transportation and storage capacity to meet natural gas demands. The AMA is in effect through March 31, 2022; both entities plan to extend this AMA prior to its expiration. It also requires SJRG to pay minimum annual fees of $4.25 million to ETG and includes tiered margin sharing levels between ETG and SJRG (see Note 1). LITIGATION - SJI and SJG are subject to claims, actions and other legal proceedings arising in the ordinary course of business. Neither SJI nor SJG can make any assurance as to the outcome of any of these actions but, based on an analysis of these claims and consultation with outside counsel, we do not believe that any of these claims, other than described below, would be reasonably likely to have a material impact on the business or financial statements of SJI or SJG. Liabilities related to claims are accrued when the amount or range of amounts of probable settlement costs or other charges for these claims can be reasonably estimated. In August 2018, the State of New Jersey filed a civil enforcement action in the New Jersey Superior Court, Atlantic County, against SJG and several other current and former owners of certain property in Atlantic City, NJ alleging damage to the State's natural resources and seeking payment for damages to those natural resources, where SJG and its predecessors previously operated a manufactured gas plant. Assessment of the nature and extent of the alleged damages requires substantial analysis from multiple experts. To date, discovery has not yet taken place and there is limited precedent on a number of the legal matters involved. As a result, SJG is currently evaluating the merits of the State of New Jersey’s allegations. All parties have agreed to and begun mediation efforts. SJG intends to vigorously defend itself in this matter, however, an adverse outcome in the litigation could have a material impact on SJI's and SJG's results of operations, financial condition and liquidity. SJG recorded a liability based on its best-estimate of the probable outcome of this matter as of December 31, 2021. This manufactured gas plant site has been fully remediated as discussed under "Environmental Remediation Costs" below. SJI has accrued approximately $11.3 million and $4.1 million related to all claims in the aggregate as of December 31, 2021 and 2020, respectively, of which SJG has accrued approximately $10.0 million and $1.2 million as of December 31, 2021 and 2020, respectively. COLLECTIVE BARGAINING AGREEMENTS — SJI and its subsidiaries employed 1,173 and 1,130 employees as of December 31, 2021 and 2020, respectively. SJG employed 432 and 441 employees as of December 31, 2021 and 2020, respectively. As of December 31, 2021, 289 of the total number of employees were represented by labor unions at SJG, and 233 were represented by a labor union at ETG. As of December 31, 2020, 303 of the total number of employees were represented by labor unions at SJG, and 167 were represented by a labor union at ETG. Collective bargaining agreements with unions that represent SJG employees include agreements with IBEW Local 1293, which was finalized in February 2022 and now runs through February 2025, and with IAM Local 76 which was finalized in 2021 and now runs through August 2025. A collective bargaining agreement with UWUA Local 424 that represents unionized ETG employees runs through November 2022. The labor agreements cover wage increases, health and welfare benefits, paid time off programs, and other benefits. At ETG, 68 employees voted to certify as a new bargaining unit effective November 23, 2021, for which SJI is actively negotiating a new collective bargaining agreement. GUARANTEES - As of December 31, 2021, SJI, the parent company, has issued guarantees to third parties on behalf of its consolidated subsidiaries. These guarantees were issued to guarantee payment to third parties with whom SJI's consolidated subsidiaries have commodity supply contracts. As of December 31, 2021, these guarantees support future firm commitments of SJI's consolidated subsidiaries and $143.1 million of the Accounts Payable already recorded on SJI's consolidated balance sheet. As of December 31, 2021, SJI had issued $11.3 million of parental guarantees on behalf of EnergyMark, an unconsolidated subsidiary. These guarantees generally expire within one year and were issued to enable the subsidiary to market retail natural gas. AFFILIATE LOANS - SJI has provided $62.6 million and $19.3 million in capital contribution loans to REV, which are recorded in Notes Receivable - Affiliates on the consolidated balance sheets as of December 31, 2021 and 2020, respectively (see Note 3). The amount of capital contribution loans may be amended upward from time to time at the sole discretion of SJI. CONVERTIBLE UNITS - The Company has a contract obligating the holder of the Equity Units to purchase from the Company, and for the Company to sell to the holder for a price in cash of $50, a certain number of shares of common stock. In April 2021, a similar contract related to SJI's Convertible Units was settled. See Note 6. ENVIRONMENTAL REMEDIATION COSTS — SJG incurred and recorded costs for environmental cleanup of 12 sites where SJG or its predecessors operated gas manufacturing plants. SJG stopped manufacturing gas in the 1950s. ETG is subject to environmental remediation liabilities associated with 5 former manufactured gas plant sites in New Jersey. These environmental remediation expenditures are recoverable from customers through the RAC mechanism approved by the BPU (see Note 10). SJI and some of its nonutility subsidiaries also recorded costs for environmental cleanup of sites where SJF previously operated a fuel oil business and Morie maintained equipment, fueling stations and storage (see Note 3). Remaining ranges of potential exposure for future remediation related to SJI's nonutility subsidiaries' sites are not material. SJI successfully entered into settlements with all of its historic comprehensive general liability carriers regarding the environmental remediation expenditures at the SJG sites. Since the early 1980s, SJI accrued environmental remediation costs of $629.6 million, of which $463.5 million was spent as of December 31, 2021. SJG accrued environmental remediation costs of $510.5 million, of which $418.5 million was spent as of December 31, 2021. The following table details the amounts expended and accrued for SJI's and SJG's environmental remediation during the last two years (in thousands): SJI (includes SJG and all other consolidated subsidiaries): 2021 2020 Beginning of Year $ 193,575 $ 232,885 Change in Accruals 9,111 (22,198) Expenditures (36,605) (17,112) End of Year $ 166,081 $ 193,575 SJG: 2021 2020 Beginning of Year $ 101,243 $ 131,262 Change in Accruals 9,398 (15,273) Expenditures (18,677) (14,746) End of Year $ 91,964 $ 101,243 The balances are segregated between current and noncurrent on the consolidated balance sheets under the captions Current Liabilities (SJI & SJG), Deferred Credits and Other Noncurrent Liabilities (SJI) and Regulatory and Other Noncurrent Liabilities (SJG). Management estimates that undiscounted future costs to clean up SJG's sites will range from $92.0 million to $154.3 million. Six of SJG's sites comprise the majority of these estimates, with future costs ranging from $83.6 million to $146.1 million. The remediation efforts at SJG's six most significant sites include the following: Site 1 - A combination of excavation and subsurface containment of impacted media has been approved by the regulatory authority for this site and work is underway. Steps remaining to remediate the site include completion of the remedial action, issuance of a Response Action Outcome, and long-term groundwater monitoring. Site 2 - Remediation of the soil contamination at this site has been completed. Steps remaining to remediate the site include completion of sediment remediation, completion of post-remediation groundwater monitoring, issuance of a Response Action Outcome, and long-term groundwater monitoring. Site 3 - A significant portion of the remedial action at this site has been completed. Steps remaining to remediate the site include completion of the approved subsurface containment remedy, issuance of a Response Action Outcome, and long term groundwater monitoring. Site 4 - The remedial action approved by the regulatory authority is currently being implemented. Remaining steps to remediate the site include post-remediation groundwater monitoring, ongoing operation of the product recovery system, and issuance of a Response Action Outcome. Site 5 - The remedial action to address impacted soil has been completed. Steps remaining include long-term groundwater monitoring and issuance of a Response Action Outcome. Site 6 - The remedial action to address impacted soil has been completed. Steps remaining include long-term groundwater monitoring and issuance of a Response Action Outcome. Management estimates that undiscounted future costs to clean up ETG's sites will range from $73.6 million to $137.9 million. The remediation efforts at ETG's five sites include the following: Site 1 - The remedial action approved by the regulatory authority is currently being implemented. Steps remaining to remediate the site include completion of the remedial action, issuance of a Response Action Outcome, and long-term groundwater monitoring. Site 2 - The remedial action to address impacted soil has been completed. Steps remaining include long-term groundwater monitoring and issuance of a Response Action Outcome. Site 3 - Permitting is underway for a soil and sediment remedial action at the site that has recently been approved by the regulatory authority. Steps remaining to fully remediate the site include implementation of the approved remedy, long-term groundwater monitoring, and issuance of a Response Action Outcome. Site 4 - Soil remediation for the on-site portion of the work has been completed and an unrestricted use Response Action Outcome-A has been issued. Steps remaining to fully remediate the site include implementation of the remedial action proposed for the remaining areas, long-term groundwater monitoring, and issuance of a Response Action Outcome. Site 5 - Soil remediation for a portion of the site has been completed; investigations to characterize the remaining impacts are underway. Steps remaining to fully remediate the site include implementation of a remedial action for the remaining areas, long-term groundwater monitoring, and issuance of a Response Action Outcome. SJI and SJG recorded the lower end of the above-mentioned ranges as a liability because a single reliable estimation point is not feasible due to the amount of uncertainty involved in the nature of projected remediation efforts and the long period over which remediation efforts will continue. Recorded amounts include estimated costs based on projected investigation and remediation work plans using existing technologies. Actual costs could differ from the estimates due to the long-term nature of the projects, changing technology, government regulations and site-specific requirements. Significant risks surrounding these estimates include unforeseen market price increases for remedial services, property owner acceptance of the selected remedy, regulatory approval of the selected remedy and remedial investigative findings.

DERIVATIVE INSTRUMENTS

Derivative Instruments and Hedging Activities Disclosure [Abstract]
DERIVATIVE INSTRUMENTS	DERIVATIVE INSTRUMENTS: Certain SJI subsidiaries, including SJG, are involved in buying, selling, transporting and storing natural gas, and buying and selling retail electricity for their own accounts as well as managing these activities for third parties. These subsidiaries are subject to market risk on expected future purchases and sales due to commodity price fluctuations. Management takes an active role in the risk management process and has developed policies and procedures that require specific administrative and business functions to assist in identifying, assessing and controlling various risks. Management reviews any open positions in accordance with strict policies to limit exposure to market risk. These derivative instruments include forward contracts, swap agreements, options contracts and futures contracts. As of December 31, 2021, SJI and SJG had outstanding derivative contracts as follows: SJI Consolidated SJG Derivative contracts intended to limit exposure to market risk to: Expected future purchases of natural gas (in MMdts) 96.7 10.3 Expected future sales of natural gas (in MMdts) 130.2 0.8 Basis and Index related net purchase/(sale) contracts (in MMdts) 72.1 1.5 These contracts, which have not been designated as hedging instruments under GAAP, are measured at fair value and recorded in Derivatives - Energy Related Assets or Derivatives - Energy Related Liabilities on the consolidated balance sheets of SJI and SJG. For SJE and SJRG contracts, the net unrealized pre-tax gains (losses) for these energy-related commodity contracts are included with realized gains (losses) in Operating Revenues – Nonutility on the consolidated statements of income for SJI. These unrealized pre-tax gains (losses) were $5.6 million, $0.4 million and $(11.7) million for the years ended December 31, 2021, 2020 and 2019, respectively. For SJG's and ETG's contracts, the costs or benefits are recoverable through the BGSS clause, subject to BPU approval. As a result, unrealized gains (losses) for SJG's and ETG's energy-related commodity contracts are included with realized gains and losses in Regulatory Assets or Regulatory Liabilities on the consolidated balance sheets of SJI (ETG and SJG) and SJG. As of December 31, 2021 and 2020, SJI had $22.1 million and $2.4 million, respectively, and SJG had $7.1 million and $1.1 million, respectively, of unrealized gains (losses) included in its BGSS regulatory accounts related to energy-related commodity contracts. As part of its gas purchasing strategy, SJG uses financial contracts through SJRG to limit exposure to forward price risk. The costs or benefits of these short-term contracts are recoverable through SJG's BGSS clause, subject to BPU approval. See Note 3 for more information about these related party transactions. The retail electric operations of SJE use forward physical and financial contracts to mitigate commodity price risk on fixed price electric contracts. However, expected future purchases and sales of electricity are not material. SJG has interest rate derivatives to mitigate exposure to increasing interest rates and the impact of those rates on cash flows of variable-rate debt. These interest rate derivatives are measured at fair value and recorded in Derivatives - Other on the consolidated balance sheets. The fair value represents the amount SJG would have to pay the counterparty to terminate these contracts as of those dates. As of December 31, 2021, SJG's active interest rate swaps were as follows: Notional Amount Fixed Interest Rate Start Date Maturity $ 12,500,000 3.530% 12/1/2006 2/1/2036 $ 12,500,000 3.430% 12/1/2006 2/1/2036 Unrealized losses on these interest rate derivatives for SJG totaled $8.0 million and $9.9 million as of December 31, 2021 and 2020, respectively. For these unrealized losses, management believes that, subject to BPU approval, the market value upon termination can be recovered in rates and, therefore, they have been recorded in Regulatory Assets in the consolidated balance sheets. See Note 11. SJI had interest rate derivatives that were terminated in December 2020 at a price equal to the fair value of the instruments of $8.2 million, which was recorded to Interest Charges on the consolidated statements of income for the year ended December 31, 2020. The fair values of all derivative instruments, none of which are designated as hedging instruments under GAAP, as reflected in the consolidated balance sheets as of December 31, are as follows (in thousands): SJI (includes SJG and all other consolidated subsidiaries): December 31, 2021 December 31, 2020 Assets Liabilities Assets Liabilities Energy-related commodity contracts: Derivatives - Energy Related - Current $ 95,041 $ 60,002 $ 41,439 $ 27,006 Derivatives - Energy Related - Noncurrent 22,488 16,079 6,935 4,947 Interest rate contracts: Derivatives - Other - Current — 568 — 659 Derivatives - Other - Noncurrent — 7,432 — 9,279 Total Derivatives $ 117,529 $ 84,081 $ 48,374 $ 41,891 SJG: December 31, 2021 December 31, 2020 Assets Liabilities Assets Liabilities Energy-related commodity contracts: Derivatives – Energy Related – Current $ 9,396 $ 2,520 $ 4,053 $ 2,868 Derivatives – Energy Related – Noncurrent 507 324 87 190 Interest rate contracts: Derivatives - Other - Current — 568 — 659 Derivatives - Other - Noncurrent — 7,432 — 9,279 Total Derivatives $ 9,903 $ 10,844 $ 4,140 $ 12,996 SJI and SJG enter into derivative contracts with counterparties, some of which are subject to master netting arrangements, which allow net settlements under certain conditions.

FAIR VALUE OF FINANCIAL ASSETS AND FINANCIAL LIABILITIES	FAIR VALUE OF FINANCIAL ASSETS AND FINANCIAL LIABILITIES: GAAP establishes a hierarchy that prioritizes fair value measurements based on the types of inputs used for the various valuation techniques. The levels of the hierarchy are described below: • Level 1: Observable inputs, such as quoted prices in active markets for identical assets or liabilities. • Level 2: Inputs other than quoted prices that are observable for the asset or liability, either directly or indirectly; these include quoted prices for similar assets or liabilities in active markets and quoted prices for identical or similar assets or liabilities in markets that are not active. • Level 3: Unobservable inputs that reflect the reporting entity’s own assumptions. Assessment of the significance of a particular input to the fair value measurement requires judgment and may affect the valuation of financial assets and financial liabilities and their placement within the fair value hierarchy. For financial assets and financial liabilities measured at fair value on a recurring basis, information about the fair value measurements for each major category is as follows (in thousands): As of December 31, 2021 Total Level 1 Level 2 Level 3 Assets SJI (includes SJG and all other consolidated subsidiaries): Available-for-Sale Securities (A) $ 37 $ 37 $ — $ — Derivatives – Energy Related Assets (B) 117,529 56,260 52,277 8,992 $ 117,566 $ 56,297 $ 52,277 $ 8,992 SJG: Assets Derivatives – Energy Related Assets (B) $ 9,903 $ 4,648 $ 1,617 $ 3,638 $ 9,903 $ 4,648 $ 1,617 $ 3,638 SJI (includes SJG and all other consolidated subsidiaries): Liabilities Derivatives – Energy Related Liabilities (B) $ 76,081 $ 21,879 $ 45,890 $ 8,312 Derivatives – Other (C) 8,000 — 8,000 — $ 84,081 $ 21,879 $ 53,890 $ 8,312 SJG: Liabilities Derivatives – Energy Related Liabilities (B) $ 2,844 $ 1,780 $ 1,064 $ — Derivatives – Other (C) 8,000 — 8,000 — $ 10,844 $ 1,780 $ 9,064 $ — As of December 31, 2020 Total Level 1 Level 2 Level 3 Assets SJI (includes SJG and all other consolidated subsidiaries): Available-for-Sale Securities (A) $ 32 $ 32 $ — $ — Derivatives – Energy Related Assets (B) 48,374 11,447 23,527 13,400 $ 48,406 $ 11,479 $ 23,527 $ 13,400 SJG: Assets Derivatives – Energy Related Assets (B) $ 4,140 $ 715 $ 32 $ 3,393 $ 4,140 $ 715 $ 32 $ 3,393 SJI (includes SJG and all other consolidated subsidiaries): Liabilities Derivatives – Energy Related Liabilities (B) $ 31,953 $ 8,605 $ 20,954 $ 2,394 Derivatives – Other (C) 9,938 — 9,938 — $ 41,891 $ 8,605 $ 30,892 $ 2,394 SJG: Liabilities Derivatives – Energy Related Liabilities (B) $ 3,058 $ 2,891 $ 159 $ 8 Derivatives – Other (C) 9,938 — 9,938 — $ 12,996 $ 2,891 $ 10,097 $ 8 Counterparty credit risk and the credit risk of SJI are incorporated and considered in the valuation of all derivative instruments as appropriate. The effect of counterparty credit risk and the credit risk of SJI on the derivative valuations is not significant. (A) Available-for-Sale Securities include securities that are traded in active markets and securities that are not traded publicly. The securities traded in active markets are valued using the quoted principal market close prices that are provided by the trustees and are categorized in Level 1 in the fair value hierarchy. (B) Derivatives – Energy Related Assets and Liabilities are traded in both exchange-based and non-exchange-based markets. Exchange-based contracts are valued using unadjusted quoted market sources in active markets and are categorized in Level 1 in the fair value hierarchy. Certain non-exchange-based contracts are valued using indicative price quotations available through brokers or over-the-counter, on-line exchanges and are categorized in Level 2. These price quotations reflect the average of the bid-ask mid-point prices and are obtained from sources that management believes provide the most liquid market. Management reviews and corroborates the price quotations with at least one additional source to ensure the prices are observable market information, which includes consideration of actual transaction volumes, market delivery points, bid-ask spreads and contract duration. For non-exchange-based derivatives that trade in less liquid markets with limited pricing information, model inputs generally would include both observable and unobservable inputs. In instances where observable data is unavailable, management considers the assumptions that market participants would use in valuing the asset or liability. This includes assumptions about market risks such as liquidity, volatility and contract duration. Such instruments are categorized in Level 3 in the fair value hierarchy as the model inputs generally are not observable. Management uses the discounted cash flow model to value Level 3 physical and financial forward contracts, which calculates mark-to-market valuations based on forward market prices, original transaction prices, volumes, risk-free rate of return and credit spreads. Inputs to the valuation model are reviewed and revised as needed, based on historical information, updated market data, market liquidity and relationships, and changes in third party pricing sources. The validity of the mark-to-market valuations and changes in these values from period to period are examined and qualified against historical expectations by the risk management function. If any discrepancies are identified during this process, the mark-to-market valuations or the market pricing information is evaluated further and adjusted, if necessary. (C) Derivatives-Other – Derivative instruments that are used to limit our exposure to changes in interest rates on variable-rate, long-term debt are valued using quoted prices on commonly quoted intervals, which are interpolated for periods different than the quoted intervals, as inputs to a market valuation model. Market inputs can generally be verified and model selection does not involve significant management judgment, as a result, these instruments are categorized in Level 2 in the fair value hierarchy. The following table provides quantitative information regarding significant unobservable inputs in Level 3 fair value measurements (in thousands, except for ranges): SJI (includes SJG and all other consolidated subsidiaries): Type Fair Value at December 31, 2021 Valuation Technique Significant Unobservable Input Range [Weighted Average] Assets Liabilities Forward Contracts - Natural Gas $ 8,916 $ 8,107 Discounted Cash Flow Forward price (per dt) $1.77 - $8.30 [$3.73] (A) Type Fair Value at December 31, 2020 Valuation Technique Significant Unobservable Input Range [Weighted Average] Assets Liabilities Forward Contracts - Natural Gas $ 12,824 $ 1,764 Discounted Cash Flow Forward price (per dt) $1.44 - $6.77 [$2.67] (A) The unobservable inputs in Level 3 fair value measurements of forward electric contracts as of December 31, 2021 and 2020 are not material.

Revenue from Contract with Customer [Abstract]
REVENUES	REVENUES: At contract inception, SJI and SJG assess the goods and services promised in all of its contracts with customers, and identify a performance obligation for each promise to transfer to a customer a distinct good or service. As applicable for each revenue stream and customer contract type, SJI and SJG follow two approaches: • SJI and SJG have elected the practical expedient in ASC 606, Revenues from Contracts with Customers, for recognizing revenue on contracts with customers on a portfolio of performance obligations with similar characteristics, as we reasonably expect the effects of applying the guidance to the portfolio would not differ materially from applying it to individual contracts. • SJI and SJG apply the accounting guidance for recognizing revenue on contracts with customers on a series of distinct goods and services as one performance obligation, as long as the distinct goods and services are part of a series that are substantially the same and satisfied over time, and the same method would be used to measure progress towards satisfaction of the performance obligation. All performance obligations noted below under "Revenue Recognized Over Time" apply this guidance. Below is a listing of all performance obligations that arise from contracts with customers, along with details on the satisfaction of each performance obligation, the significant payment terms, and the nature of the goods and services being transferred: Revenue Recognized Over Time: Reportable Segment Performance Obligation Description SJG Utility Operations ETG Utility Operations ELK Utility Operations Wholesale Energy Operations Natural Gas SJG, ETG and, prior to its sale in July 2020 (see Note 1), ELK, sell natural gas to residential, commercial and industrial customers, and price is based on regulated tariff rates which are established by the BPU or the MPSC, as applicable. There is an implied contract with a customer for the purchase, delivery, and sale of gas, and the customer is billed monthly, with payment due within 30 days. Payments are received from certain customers based on a predetermined budget billing schedule. Budget billing does not represent a contract asset or liability but rather just a receivable/liability because there are no further performance obligations required to be satisfied before the Utilities have the right to collect/refund the customer’s consideration. Consideration is due when control of the energy is transferred to the customer and is satisfied with the passage of time. Budget billing liability balances are recorded within the Customer Deposits and Credit Balances line item in the consolidated balance sheets. SJG has direct connections to and long-term gas transmission services on interstate pipeline systems. The sale of gas to third parties from these pipelines prior to entering our service territory is considered OSS. These contracts to sell off-system are at a price, quantity and time period agreed to by both parties determined on a contract by contract basis. SJRG sells natural gas to commercial customers at either a fixed quantity or at variable quantities based on a customer's needs. Payment is due on the 25th of each month for the previous month's deliveries. Revenue is currently being recognized over time based upon volumes delivered (i.e., unit of output) or through the passage of time ratably as the customer uses natural gas, which represents satisfaction of the performance obligation. SJG Utility Operations Wholesale Energy Operations Pipeline Transportation Capacity SJG and SJRG sell pipeline transportation capacity on a wholesale basis to various customers on the interstate pipeline system and transport natural gas purchased directly from producers or suppliers to their customers (for SJG, this is known as Capacity Release). These contracts to sell this capacity are at a price, quantity and time period agreed to by both parties determined on a contract by contract basis. Payment is due on the 25th of each month for the previous month's deliveries. Revenue is currently being recognized over time based upon volumes delivered (i.e., unit of output) or through the passage of time ratably coinciding with the delivery of gas and the customer obtaining control, which represents satisfaction of the performance obligation. Wholesale Energy Operations Fuel Management Services SJRG currently has several fuel supply management contracts where SJRG has acquired pipeline transportation capacity that allows SJRG to match end users, many of which are merchant generators, with producers looking to find a long-term solution for their supply. Natural gas is sold to the merchant generator daily based on its needs, with payment made either weekly or biweekly depending on the contract. Revenue is currently being recognized over time based upon volumes delivered (i.e., unit of output) coinciding with the delivery of gas and the customer obtaining control, which represents satisfaction of the performance obligation. Retail Services Electricity SJE sells electricity to commercial, industrial and residential customers at fixed prices throughout the life of the contract, with the customer billed monthly and payment due within 30 days. Revenue is currently being recognized over time based upon volumes delivered (i.e., unit of output) or through the passage of time ratably coinciding with the delivery of electricity and the customer obtaining control, which represents satisfaction of the performance obligation. Renewables Solar Solar projects earn revenue based on electricity generated. The customer is billed monthly as electricity is being generated, with payment due within 30 days. The performance obligation is satisfied as kilowatt hours of energy are generated (i.e., unit of output), which is when revenue is recognized. Renewables Fuel Cell The fuel cell projects earn revenue based on electricity generated. The customer is billed monthly as electricity is being generated, with payment due within 30 days. The performance obligation is satisfied as kilowatt hours of energy are generated (i.e., unit of output), which is when revenue is recognized. Renewables CHP Marina sold MTF/ACB in February 2020 (see Note 1). Prior to its sale, Marina had a contract with a casino and resort in Atlantic City, NJ to provide cooling, heating and emergency power. There were multiple performance obligations with this contract, including electric, chilled water and hot water, and each of these was considered distinct and separately identifiable performance obligations that were all priced separately. These performance obligations were satisfied over time ratably as they were used by the customer, who was billed monthly. Retail Services Energy Procurement Consulting Services AEP and EnerConnex provide energy procurement consulting services. These businesses match energy suppliers with end users and are paid commissions by energy suppliers. The commissions received on energy procurement contracts (whether received at the beginning of a contract or paid under monthly terms) are earned and recognized over the duration of the underlying contracts as energy usage occurs, which represents satisfaction of the performance obligation. The resulting contract liabilities are not material as of December 31, 2021, 2020 and 2019. Revenue Recognized at a Point in Time: Reportable Segment Performance Obligation Description Renewables SRECs The customer is billed based on a contracted amount of SRECs to be sold, with the price based on the market price of the SRECs at the time of generation. This does not represent variable consideration as the price is known and established at the time of generation and delivery to the customer. The performance obligation is satisfied at the point in time the SREC is delivered to the customer, which is when revenue is recognized. Payment terms are approximately 10 days subsequent to delivery. For all revenue streams listed above, revenue is recognized using the practical expedient in ASC 606, which allows an entity to recognize revenue in the amount that is invoiced, as long as that amount corresponds to the value to the customer ("Invoiced Practical Expedient"). SJI's and SJG's contracts with customers discussed above are at prices that are known to the customer at the time of delivery, either through regulated tariff rates, a fixed contractual price or market prices that are established and tied to each delivery. These amounts match the value to the customer as they are purchasing and obtaining the good or service on the same day at the agreed-upon price. This eliminates any variable consideration in transaction price, and as a result revenue is recognized at this price at the time of delivery. SJI and SJG have determined that the above methods provide a faithful depiction of the transfer of goods or services to the customer. For all above performance obligations, SJI's and SJG's efforts are expended throughout the contract based on seasonality and customer needs. Further, for various contracts among each performance obligation, SJI (specifically SJRG) may have a stand ready obligation to provide goods or services on an as needed basis to the customer. Because the Invoiced Practical Expedient is used for recognizing revenue, SJI and SJG further adopted the practical expedient in ASC 606 that allows both companies to not disclose additional information regarding remaining performance obligations. SJI and SJG disaggregate revenue from contracts with customers into customer type and product line. SJI and SJG have determined that disaggregating revenue into these categories achieves the disclosure objective in ASC 606 to depict how the nature, timing and uncertainty of revenue and cash flows are affected by economic factors. Further, disaggregating revenue into these categories is consistent with information regularly reviewed by the CODM in evaluating the financial performance of SJI's operating segments. SJG only operates in the SJG Utility Operations segment. See Note 8 for further information regarding SJI's operating segments. Disaggregated revenues from contracts with customers are disclosed below, by operating segment, for the years ended December 31, (in thousands). The presentation of disaggregated revenues for the prior periods has been revised to conform to the realignment of our operating segments as discussed in Note 8. 2021 SJG Utility Operations ETG Utility Operations Wholesale Energy Operations Retail Services Renewables Corporate Services and Intersegment Total Customer Type: Residential $ 359,963 $ 225,209 $ — $ 1,997 $ — $ — $ 587,169 Commercial & Industrial 166,287 129,148 1,406,155 8,918 24,038 (21,795) 1,712,751 OSS & Capacity Release 10,720 — — — — — 10,720 Other 3,022 811 — 4,881 — (524) 8,190 $ 539,992 $ 355,168 $ 1,406,155 $ 15,796 $ 24,038 $ (22,319) $ 2,318,830 Product Line: Gas $ 539,992 $ 355,168 $ 1,406,155 $ — $ — $ (21,617) $ 2,279,698 Electric — — — 8,919 — (178) 8,741 Solar — — — — 7,019 — 7,019 Fuel Cells — — — — 15,763 — 15,763 Other — — — 6,877 1,256 (524) 7,609 $ 539,992 $ 355,168 $ 1,406,155 $ 15,796 $ 24,038 $ (22,319) $ 2,318,830 2020 SJG Utility Operations ETG Utility Operations ELK Utility Operations Wholesale Energy Operations Retail Services Renewables Corporate Services and Intersegment Total Customer Type: Residential $ 349,111 $ 223,221 $ 2,179 $ — $ 1,978 $ — $ — $ 576,489 Commercial & Industrial 144,300 114,300 2,544 683,152 22,176 15,617 (10,048) 972,041 OSS & Capacity Release 7,673 — — — — — — 7,673 Other 2,048 1,629 203 — — — — 3,880 $ 503,132 $ 339,150 $ 4,926 $ 683,152 $ 24,154 $ 15,617 $ (10,048) $ 1,560,083 Product Line: Gas $ 503,132 $ 339,150 $ 4,926 $ 683,152 $ — $ — $ (7,544) $ 1,522,816 Electric — — — — 19,907 — (1,971) 17,936 Solar — — — — — 8,426 — 8,426 CHP — — — — — 3,502 — 3,502 Other — — — — 4,247 3,689 (533) 7,403 $ 503,132 $ 339,150 $ 4,926 $ 683,152 $ 24,154 $ 15,617 $ (10,048) $ 1,560,083 2019 SJG Utility Operations ETG Utility Operations ELK Utility Operations Wholesale Energy Operations Retail Services Renewables Corporate Services and Intersegment Total Customer Type: Residential $ 356,646 $ 217,195 $ 3,494 $ — $ 16,206 $ — $ — $ 593,541 Commercial & Industrial 116,959 103,590 4,197 633,720 43,345 48,748 (13,368) 937,191 OSS & Capacity Release 8,951 — — — — — — 8,951 Other 2,456 10,242 166 — — — — 12,864 $ 485,012 $ 331,027 $ 7,857 $ 633,720 $ 59,551 $ 48,748 $ (13,368) $ 1,552,547 Product Line: Gas $ 485,012 $ 331,027 $ 7,857 $ 633,720 $ — $ — $ (5,433) $ 1,452,183 Electric — — — — 56,899 — (7,935) 48,964 Solar — — — — — 15,111 — 15,111 CHP — — — — — 27,993 — 27,993 Other — — — — 2,652 5,644 — 8,296 $ 485,012 $ 331,027 $ 7,857 $ 633,720 $ 59,551 $ 48,748 $ (13,368) $ 1,552,547 The SJG balance is a part of the SJG Utility Operations segment, and is before intercompany eliminations with other SJI entities. Revenues on the consolidated statements of income that are not with contracts with customers consist of (a) revenues from alternative revenue programs at the SJG, ETG and ELK utility operating segments (primarily CIP and WNC), (b) both utility and nonutility realized revenue from derivative contracts at the SJG and ETG Utility Operations, Wholesale Energy Operations, and Retail Services operating segments, and (c) unrealized revenues from derivative contracts at the Wholesale Energy Operations and Retail Services operating segments (see Note 16). The Utilities' rate mechanisms that qualify as alternative revenue programs are described in Note 10. These mechanisms are subject to compliance filings on at least an annual basis, and the tariff rate adjustments are designed to occur over this compliance period. These rate mechanisms satisfy the criteria in ASC 980-605-25-4, as (a) each mechanism is established by order of the BPU for SJG and ETG, and the MPSC for ELK; (b) the amounts recoverable under each program are determined by tracking and are probable of recovery; and (c) the adjustments to tariff rates are designed to recover from or refund to customers within a 24 month period. For each individual rate reconciling mechanism, operating revenues are recognized when allowable costs are greater than the amounts billed in the current period and are reduced when allowable costs are less than amounts billed in the current period. Total revenues arising from alternative revenue programs at SJI were $17.8 million, $38.1 million and $29.0 million for the years ended December 31, 2021, 2020 and 2019, respectively. Total revenues arising from alternative revenue programs at SJG were $13.0 million, $28.0 million and $34.8 million for the years ended December 31, 2021, 2020 and 2019, respectively. The following table provides information about SJI's and SJG's receivables and unbilled revenue from contracts with customers (in thousands): Accounts Receivable (a) Unbilled Revenue (b) SJI (including SJG and all other consolidated subsidiaries): Beginning balance as of January 1, 2021 $ 278,723 $ 85,423 Ending balance as of December 31, 2021 343,835 87,357 Increase (Decrease) $ 65,112 $ 1,934 Beginning balance as of January 1, 2020 $ 253,661 $ 84,821 Ending balance as of December 31, 2020 278,723 85,423 Increase (Decrease) $ 25,062 $ 602 SJG: Beginning balance as of January 1, 2021 $ 88,657 $ 46,837 Ending balance as of December 31, 2021 125,848 43,236 Increase (Decrease) $ 37,191 $ (3,601) Beginning balance as of January 1, 2020 $ 84,940 $ 45,016 Ending balance as of December 31, 2020 88,657 46,837 Increase (Decrease) $ 3,717 $ 1,821 (a) A receivable is SJI's and SJG's right to consideration that is unconditional, as only the passage of time is required before payment is expected from the customer. (b) All unbilled revenue for SJI and SJG arises from contracts with customers. Unbilled revenue relates to SJI's and SJG's right to receive payment for commodity delivered but not yet billed. This represents contract assets that arise from contracts with customers, which is defined in ASC 606 as the right to payment in exchange for goods already transferred to a customer, excluding any amounts presented as a receivable. The unbilled revenue is transferred to accounts receivable when billing occurs and the rights to collection become unconditional.

Business Combinations [Abstract]
ACQUISITIONS & BUSINESS COMBINATIONS	ACQUISITIONS & BUSINESS COMBINATIONS During the years ended December 31, 2021 and 2020, SJI completed several acquisitions and business combinations as described below. In each case, the amount of revenues and net income included in the Company’s consolidated statements of income for the year of the acquisition was not material. For the EnerConnex transaction, which was accounted for as a business combination, our results would not have been materiality different for the periods presented prior to the acquisition if the acquisition had occurred at the beginning of those periods. In addition, the amounts of acquisition-related costs were not material for these transactions. Catamaran Joint Venture On August 12, 2020, SJI, through its wholly-owned subsidiary Marina, formed the Catamaran joint venture with a third party partner. Catamaran was formed for the purpose of developing, owning and operating renewable energy projects, and supporting SJI's commitment to clean energy initiatives. The following acquisitions have occurred under the Catamaran joint venture since its initiation: Bronx Midco Catamaran and a third party formed Bronx Midco, of which Catamaran owns 99%. On June 9, 2021, Bronx Midco purchased a fuel cell project totaling 5 MW in Bronx, New York that is in the process of being constructed and is expected to be completed in the second quarter of 2022. Marina, through its ownership in Catamaran, has a 92% ownership interest in Bronx Midco, and, as a result, Marina consolidates the entity as Marina has the power to direct the activities of the entity that most significantly impact the entity’s economic performance. ASC Topic 805, “Business Combinations,” states that a business is an integrated set of activities and assets that is capable of being conducted and managed for the purpose of providing a return in the form of dividends, lower costs, or other economic benefits directly to investors or other owners, members, or participants. As the acquisition did not meet the definition of a business combination under ASC 805, the Company accounted for the transaction as an asset acquisition. In an asset acquisition, goodwill is not recognized, but rather any excess consideration transferred over the fair value of the net assets acquired is allocated on a relative fair value basis to the identifiable net assets. The fuel cell project includes a land lease (see Note 9) and, at the time of the acquisition, working capital. The total expected cost of the fuel cell project is $60.1 million, of which the partners have paid $28.7 million as of December 31, 2021. Of this total, Marina invested $26.4 million as of December 31, 2021. To account for the third party partners' interest in Bronx Midco, Marina recorded $2.3 million of Noncontrolling Interests in Total Equity on the consolidated balance sheets as of December 31, 2021. The major depreciable assets of the Bronx Midco fuel cell project are the fuel cell modules, which will be depreciated over their estimated useful lives of 35 years once placed in service. The lease cost associated with the land lease is being recognized on a straight-line basis over the lease term of 35 years (see Note 9). All assets and financial results of Bronx Midco are included in the Renewables segment. As this project is not yet placed into service, no revenues have been recorded, expenses incurred in the Company's consolidated statements of income in 2021 are not material, and no ITC has been recorded in 2021. Annadale On August 12, 2020, Catamaran purchased 100% ownership in Annadale, an entity that owns two fuel cell projects totaling 7.5 MW in Staten Island, New York. Construction was completed after the acquisition and these fuel cell projects became operational in December 2020. Marina has a 93% ownership interest in Annadale, and Marina consolidates the entity as Marina has the power to direct the activities of the entity that most significantly impact the entity’s economic performance. Since the acquisition of Annadale did not meet the definition of a business combination under ASC 805, the Company accounted for the transaction as an asset acquisition. The acquisition of Annadale included a land lease (see Note 9) and working capital. Marina invested $80.2 million in Annadale as part of the $86.2 million total cost of the fuel cell project, with the remaining $6.0 million being contributed by the noncontrolling minority interest owner, which is recorded as Noncontrolling Interests within Total Equity on the consolidated balance sheets as of December 31, 2021. The acquisition was primarily comprised of $80.6 million in Nonutility Property, Plant & Equipment, $23.9 million in Cash and Cash Equivalents, and $4.3 million in Other Noncurrent Assets, partially offset by $21.2 million in Accounts Payable and Other Current & Noncurrent Liabilities. The major depreciable assets of Annadale are the fuel cell modules, which are being depreciated over their estimated useful lives of 35 years (see Note 1). The land lease is being amortized over the lease term of 35 years (see Note 9). All assets and financial results of Annadale are included in the Renewables segment. EnerConnex Acquisition On August 7, 2020, SJI, through its wholly-owned subsidiary SJEI, completed its acquisition of the remaining 75% of EnerConnex for total consideration of $7.5 million. This acquisition supported the Company's initiative to expand its energy consulting business. EnerConnex does not have any regulated operations. The acquisition of EnerConnex was accounted for as a business combination using the acquisition method of accounting in accordance with ASC 805. Under the acquisition method of accounting, the total estimated purchase price of an acquisition is allocated to the net assets based on their estimated fair values. Prior to this transaction, SJEI previously had a 25% investment in EnerConnex that was accounted for under the equity method of accounting. As this was a business combination achieved in stages, an approximately $2.0 million (pre-tax) gain was recorded in 2020 as a result of remeasuring the carrying value of the previously held equity interest in EnerConnex to its acquisition date fair value. This gain was recorded in Other Income on the consolidated statements of income in 2020. The acquisition date fair value of the previously held equity interest was $2.5 million and was determined based on the cash consideration exchanged for the remaining 75% of EnerConnex. The total of the $7.5 million in cash consideration for the remaining 75%, the $2.5 million acquisition date fair value of the previously held interest, and $0.2 million in assumed liabilities served as the total allocable basis shown in the preliminary purchase price allocation below. The purchase price allocation to the assets acquired and liabilities assumed as of the acquisition date for EnerConnex was finalized during 2021 with no significant adjustment and is as follows: EnerConnex Cash $ 415 Accounts Receivable 249 Identifiable Intangible Assets (A) 4,500 Goodwill 4,890 Other Noncurrent Assets 100 Total assets acquired 10,154 Accounts Payable 4 Other Current Liabilities 150 Total liabilities assumed 154 Total net assets acquired $ 10,000 (A) The identifiable intangible asset balances shown in the table above are related to customer relationships acquired in the transaction, and are included in Other Noncurrent Assets on the consolidated balance sheets. See Note 21. All assets and financial results of EnerConnex are included in the Retail Services segment. Solar Projects Acquisitions In 2021, SJI, through its wholly-owned subsidiary Marina, completed its acquisitions of a solar project in New Jersey. Also in 2021, Catamaran completed its acquisition of a solar project in Massachusetts, of which Marina has a 90% ownership interest. On June 30, 2020 and August 21, 2020, SJI acquired three LLCs and a fourth LLC, respectively. The total purchase price for these solar projects/entities, which equaled the fair value of property, plant, and equipment that was acquired in the transactions, was not material. Costs related to these acquisitions were not material. The purchase of these projects/entities is in support of the New Jersey Energy Master Plan. All assets and financial results of these projects/entities are included in the Renewables segment. RNG Dairy Farm Development Rights Acquisition On December 23, 2020, SJI completed its asset acquisition of renewable natural gas development rights in certain dairy farms, previously owned by REV, for total consideration of $10.0 million. The development rights are associated with dairy farms that will be developed as RNG projects. This acquisition is consistent with SJI's commitment to decarbonization, as REV, which we will contract with to assist in developing these RNG projects, specializes in the development, production and transportation of renewable natural gas, liquified natural gas and compressed natural gas. Among its service offerings, REV acquires the rights to build anaerobic digesters on dairy farms to produce RNG for injection into natural gas pipelines.

Goodwill and Intangible Assets Disclosure [Abstract]
GOODWILL AND IDENTIFIABLE INTANGIBLE ASSETS	GOODWILL AND IDENTIFIABLE INTANGIBLE ASSETS: GOODWILL - Goodwill represents future economic benefits arising from other assets acquired in a business combination that are not individually identified and separately recognized. Goodwill is initially measured at cost, being the excess of the aggregate of the consideration paid or transferred over the fair value of identifiable net assets acquired. Goodwill is not amortized, but instead is subject to impairment testing on an annual basis, and between annual tests whenever events or changes in circumstances indicate that the fair value of a reporting unit may be below its carrying amount. The Company performs its annual goodwill impairment test as of October 1 of each fiscal year beginning with a qualitative assessment at the reporting unit level. The reporting unit level is identified by assessing whether the components of our operating segments constitute businesses for which discrete financial information is available, whether segment management regularly reviews the operating results of those components and whether the economic and regulatory characteristics are similar. Factors utilized in the qualitative analysis performed on goodwill in our reporting units include, among other things, macroeconomic conditions, industry and market considerations, cost factors, overall financial performance, company specific operating results and other relevant entity-specific events affecting individual reporting units. If sufficient qualitative factors exist, potential goodwill impairment is evaluated quantitatively by comparing the fair value of a reporting unit to the book value, including goodwill. For each reporting unit, the Company estimates the fair value of a reporting unit using a discounted cash flow analysis (an income approach) and, for certain reporting units, management also considers other methods, which include a market multiples analysis, and performs a weighted combination of the income approach and the market approach. Determining the fair value of a reporting unit requires judgment and the use of significant estimates and assumptions. Such estimates and assumptions include, but are not limited to, forecasts of future operating results, discount and growth rates, capital expenditures, tax rates, projected terminal values and, in the cases where market multiples analysis is utilized, implied market multiples for a selected group of peer companies. If the fair value exceeds book value, goodwill of the reporting unit is not considered impaired. If the book value exceeds fair value, an impairment charge is recognized for the excess up until the amount of goodwill allocated to the reporting unit. Changes in estimates or the application of alternative assumptions could produce significantly different results. As a result of the COVID-19 pandemic and the resulting macroeconomic market conditions during 2020, the Company determined it necessary to perform a quantitative goodwill impairment analysis on the goodwill at the ETG reporting unit as of March 31, 2020 and again as of September 30, 2020. There were no impairments recorded as a result of these impairment tests. In 2021, there were no additional triggering events; as such, the Company performed its annual impairment test as of October 1, 2021. In preparing the ETG goodwill impairment test, the fair value of the ETG reporting unit was calculated using a weighted combination of the income approach, which estimates fair value based on discounted cash flows, and the market approach, which estimates fair value based on market comparables within the utility and energy industries. Determining the fair value of the ETG reporting unit requires judgment and the use of significant estimates and assumptions as discussed above. Based on the analysis performed, the fair value of the ETG reporting unit closely approached, but exceeded, its carrying amount. Should economic conditions deteriorate in future periods or remain depressed for a prolonged period of time, estimates of future cash flows and market valuation assumptions may not be sufficient to support the carrying value, requiring impairment charges in the future. The following table summarizes the changes in goodwill for the years ended December 31, 2021 and 2020, respectively (in thousands): 2021 2020 Beginning Balance, January 1 $ 706,960 $ 702,070 Goodwill from EnerConnex Acquisition at Retail Services segment (see Note 20) — 4,890 Ending Balance, December 31 $ 706,960 $ 706,960 As of December 31, 2021 and 2020, $700.2 million was included in the ETG Utility Operations segment and $6.8 million was included in the Retail Services segment. In 2019, as a result of the agreement to sell MTF & ACB (see Note 1), the Company recorded a $3.6 million impairment charge on goodwill due to the purchase price being less than the total carrying value. This impairment charge was taken at the Renewables segment and recorded to Impairment Charges on the consolidated statements of income. The Company concluded, based on the results of its at least annual goodwill impairment assessments performed for all reporting units during the years ended December 31, 2021, 2020 and 2019, that there were no additional goodwill impairments identified. IDENTIFIABLE INTANGIBLE ASSETS - The primary identifiable intangible assets of the Company are customer relationships within the Retail Services segment, interconnection and power purchase agreements at Annadale (collectively "Annadale intangible assets"), and an AMA within the ETG Utility Operations segment. The Company determines the useful lives of identifiable intangible assets after considering the specific facts and circumstances related to each intangible asset. Considerations may include the contractual term of any agreement related to the asset, the historical performance of the asset, the Company's long-term strategy for using the asset, any laws or other local regulations which could impact the useful life of the asset, and other economic factors, including competition and specific market conditions. Intangible assets that are deemed to have definite lives (finite-lived intangible assets) are amortized, primarily on a straight-line basis, over their useful lives, generally ranging from 2 to 20 years. The fair value of intangible assets is determined based on quoted market prices in active markets, if available. If quoted market prices are not available, the fair value of intangible assets is determined based upon the present values of expected future cash flows using discount rates and other assumptions believed to be consistent with those used by principal market participants, or upon estimated replacement cost, if expected future cash flows from the intangible asset are not determinable. No impairment charges were taken on identifiable intangible assets in 2021 and 2020. In 2019, as a result of the agreement to sell MTF & ACB (see Note 1), the Company recorded a $4.8 million impairment charge on identifiable intangible assets due to the purchase price being less than the total carrying value. This impairment charge was taken at the Renewables segment and recorded to Impairment Charges on the consolidated statements of income. SJI's identifiable intangible assets were as follows (in thousands): As of December 31, 2021 Gross Cost Accumulated Amortization Identifiable Intangible Assets, Net Identifiable intangible assets subject to amortization: Customer Relationships $ 8,881 $ (863) $ 8,018 AMA (See Note 1) 19,200 (17,920) 1,280 Annadale Intangible Assets 4,220 (280) $ 3,940 Other 807 (2) 805 Total $ 33,108 $ (19,065) $ 14,043 As of December 31, 2020 Gross Cost Accumulated Amortization Identifiable Intangible Assets, Net Identifiable intangible assets subject to amortization: Customer Relationships $ 6,900 $ (338) $ 6,562 AMA (See Note 1) 19,200 (12,800) 6,400 Annadale Intangible Assets 4,318 (22) 4,296 Total $ 30,418 $ (13,160) $ 17,258 The net identifiable intangible asset balances shown in the table above are included in Other Noncurrent Assets on the consolidated balance sheets as of December 31, 2021 and 2020, respectively. Total SJI amortization expense related to identifiable intangible assets was $5.9 million, $5.4 million, and $6.1 million for the years ended December 31, 2021, 2020, and 2019, respectively. As of December 31, 2021, SJI's estimated amortization expense related to identifiable intangible assets for each of the five succeeding fiscal years is as follows (in thousands): Year ended December 31, SJI 2022 $ 2,176 2023 $ 896 2024 $ 896 2025 $ 896 2026 $ 896 The decreases in estimated amortization expense in the table above are due to the AMA ceasing in March 2022 (see Note 1).

Notes to Condensed Financial Statements 1. BASIS OF PRESENTATION: Pursuant to rules and regulations of the SEC, the parent company only condensed financial statements of SJI do not reflect all of the information and notes normally included with financial statements prepared in accordance with GAAP in the United States. Therefore, these condensed financial statements should be read in conjunction with the consolidated financial statements and related notes included under Item 8 in this Form 10-K. Dividends were not received from subsidiaries in 2021, 2020 or 2019. On July 1, 2021, pursuant to an intercompany rental agreement, SJG (the lessor) gave possession of the Company's corporate headquarters in Folsom, NJ to SJI (the lessee), This lease is classified as an operating lease by SJI with a lease term of 10 years, which includes the noncancelable period of 5 years plus the first 5-year renewal option. There are nine additional options to renew the lease after the original term expires, totaling an additional 45 years. if renewed. After considering various entity, contract, asset and market factors, SJI concluded that the least term is 10 years as it is not reasonably certain that SJI will exercise renewal options past that point. This resulted in the recognition of an ROU asset and liability, each of $16.8 million, recorded in Other Noncurrent Assets and Other Noncurrent Liabilities, respectively. The weighted average discount rate used for this lease was 3.0% as of December 31, 2021. See additional information in Note 9 to the consolidated financial statements.

SUMMARY OF SIGNIFICANT ACCOUN_2

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	12 Months Ended
	Dec. 31, 2021
Accounting Policies [Abstract]
GENERAL	GENERAL - SJI provides a variety of energy-related products and services primarily through the following wholly-owned subsidiaries: ▪ SJIU is a holding company that owns SJG and ETG and, until its sale in July 2020, owned ELK. • SJG is a regulated natural gas utility which distributes natural gas in the seven southernmost counties of New Jersey. • ETG is a regulated natural gas utility which distributes natural gas in seven counties in northern and central New Jersey. • ELK is a regulated natural gas utility which distributes natural gas in northern Maryland. On July 31, 2020, SJI sold ELK (see "Sale of ELK" below). ▪ SJE acquires and markets electricity to retail end users. ▪ SJRG markets natural gas storage, commodity and transportation assets along with fuel management services on a wholesale basis in the mid-Atlantic, Appalachian and southern states. ▪ SJEX owns oil, gas and mineral rights in the Marcellus Shale region of Pennsylvania. ▪ Marina develops and operates on-site energy-related projects. Marina includes the Catamaran joint venture that was entered into for the purpose of developing, owning and operating renewable energy projects, and supporting SJI's commitment to clean energy initiatives. Catamaran owns Annadale and Bronx Midco, operators of fuel cell projects in New York, in which Marina, through Catamaran, owns 93% and 92%, respectively. Catamaran also owns a solar generation site in Massachusetts, in which Marina, through Catamaran, owns 90%. The remaining ownership percentages are recorded as Noncontrolling Interests in the consolidated financial statements. Previously, Marina also included MTF and ACB, which were sold in February 2020, and solar projects that were sold in 2020 and 2019 as discussed below under Divestitures. The principal wholly-owned subsidiaries of Marina are: • ACLE, BCLE, SCLE and SXLE own landfill gas-to-energy production facilities in Atlantic, Burlington, Salem and Sussex Counties, respectively, located in New Jersey. ACLE ceased operations on September 30, 2021, while BCLE, SCLE and SXLE ceased operations on June 1, 2020. • Marina owns, directly and through wholly-owned subsidiaries, solar energy projects at rooftop generation sites in New Jersey, including projects that were acquired in 2020 and 2021. ▪ SJESP receives commissions on appliance service contracts from a third party. • Midstream invests in infrastructure and other midstream projects, including the PennEast project for which development ceased in September 2021. See Note 3. • SJEI provides energy procurement and cost reduction services. The significant wholly-owned subsidiaries of SJEI include: • AEP, an aggregator, broker and consultant in the retail energy markets that matches end users with suppliers for the procurement of natural gas and electricity. • EnerConnex, an aggregator, broker and consultant in the retail and wholesale energy markets that matches end users with suppliers for the procurement of natural gas and electricity. On August 7, 2020, SJEI acquired the remaining 75% of EnerConnex, of which SJEI previously held a 25% interest.
BASIS OF PRESENTATION	BASIS OF PRESENTATION - SJI's consolidated financial statements include the accounts of SJI, its direct and indirect wholly-owned subsidiaries (including SJG) and subsidiaries in which SJI has a controlling interest. All significant intercompany accounts and transactions have been eliminated in consolidation. SJI also reports on a consolidated basis the operations of those entities listed under "Acquisitions" below as of their respective acquisition dates, along with its controlling interest in Catamaran as noted below. In management's opinion, the consolidated financial statements of SJI and SJG reflect all normal recurring adjustments needed to fairly present their respective financial positions, operating results and cash flows at the dates and for the periods presented.
RECLASSIFICATIONS	Certain prior years' data presented in the financial statements and footnotes have been reclassified to conform to the current year presentation. These reclassifications had no impact on the Company's results of operations, financial position or cash flows.
IMPAIRMENT OF LONG-LIVED ASSETS	IMPAIRMENT OF LONG-LIVED ASSETS - Long-lived assets that are held and used are reviewed for impairment whenever events or changes in circumstances indicate carrying values may not be recoverable. Such reviews are performed in accordance with ASC 360, Property, Plant and Equipment, where an impairment loss is indicated if the total undiscounted cash flows expected from an asset are less than its carrying value. An impairment charge is measured by the difference between an asset's carrying amount and fair value, with the difference recorded within Impairment Charges on the consolidated statements of income. Fair values can be determined based on agreements to sell assets as well as by a variety of valuation methods, including third-party appraisals, sales prices of similar assets, and present value techniques.
EQUITY INVESTMENTS	EQUITY INVESTMENTS - Marketable equity securities that are purchased as long-term investments are classified as Available-for-Sale Securities and carried at their fair value on the consolidated balance sheets. Any unrealized gains or losses are included in AOCL. SJI, through wholly-owned subsidiaries, holds significant variable interests in several companies but is not the primary beneficiary. Consequently, these investments are accounted for under the equity method. SJI includes the operations of these affiliated companies on a pre-tax basis in the statements of consolidated income under Equity in (Losses) Earnings of Affiliated Companies. In the event that losses and/or distributions from these equity method investments exceed the carrying value, and the Company is obligated to provide additional financial support, the excess will be recorded as either a current or non-current liability on the consolidated balance sheets. If we have provided any additional financial support to the investee, such as loans or advances, our share of losses that exceed the carrying amount of our investment are recorded against that amount of financial support. An impairment loss is recorded when there is clear evidence that a decline in value is other than temporary. See discussion of our equity method investments, including PennEast and Energenic and their related impairment losses, in Note 3.
NONCONTROLLING INTEREST	NONCONTROLLING INTERESTS - Interests held by third parties in consolidated majority-owned subsidiaries are presented as noncontrolling interests, which represents the noncontrolling stockholders’ interests in the underlying net assets of the Company’s consolidated majority-owned subsidiaries. As of December 31, 2021, SJI's noncontrolling interests balances are solely related to the Catamaran projects (see Note 20).
ESTIMATES AND ASSUMPTIONS	ESTIMATES AND ASSUMPTIONS - The consolidated financial statements were prepared to conform with GAAP. Management makes estimates and assumptions that affect the amounts reported in the consolidated financial statements and related disclosures. Therefore, actual results could differ from those estimates. Significant estimates include amounts related to regulatory accounting, energy derivatives, environmental remediation costs, legal contingencies, pension and other postretirement benefit costs, revenue recognition, goodwill, evaluation of equity method investments for other-than-temporary impairment, income taxes and allowance for credit losses. Estimates may be subject to future uncertainties, including the continued evolution of the COVID-19 pandemic and its impact on our operations and economic conditions, which could affect the fair value of the ETG reporting unit and its goodwill balance (see Note 21), as well as the allowance for credit losses and the total impact and potential recovery of incremental costs associated with COVID-19 (see Notes 7 and 11, respectively).
REGULATION	REGULATION - The Utilities are subject to the rules and regulations of the BPU. See Note 10 for a discussion of the Utilities' rate structure and regulatory actions. The Utilities maintain their accounts according to the BPU's prescribed Uniform System of Accounts. The Utilities follow the accounting for regulated enterprises prescribed by ASC 980, Regulated Operations , which allows for the deferral of certain costs (regulatory assets) and creation of certain obligations (regulatory liabilities) when it is probable that such items will be recovered from or refunded to customers in future periods. See Note 11 for more information related to regulatory assets and liabilities.
OPERATING REVENUES	OPERATING REVENUES - Gas and electric revenues are recognized in the period the commodity is delivered to customers. For retail customers (including customers of SJG) that are not billed at the end of the month, we record an estimate to recognize unbilled revenues for gas and electricity delivered from the date of the last meter reading to the end of the month. The Utilities also have revenues that arise from alternative revenue programs, which are discussed in Note 19. For ETG and SJG, unrealized gains and losses on energy-related derivative instruments are recorded in Regulatory Assets or Regulatory Liabilities on the consolidated balance sheets of SJI and SJG (see Note 16) until they become realized, in which case they are recognized in operating revenues. SJRG's gas revenues are recognized in the period the commodity is delivered, and operating revenues for SJRG include realized and unrealized gains and losses on energy-related derivative instruments. See further discussion under "Derivative Instruments." SJRG presents revenues and expenses related to its energy trading activities on a net basis in operating revenues. This net presentation has no effect on operating income or net income. The Company recognizes revenue for commissions received related to SJESP appliance service contracts, along with commissions received related to AEP and EnerConnex energy procurement service contracts, on a monthly basis as the commissions are earned. Marina recognizes revenue for renewable energy projects when output is generated and delivered to the customer, and when renewable energy credits have been transferred to the third party at an agreed upon price. See further information in Note 19. We considered the impact the COVID-19 pandemic has had on operating revenues, noting that SJI and SJG have not seen a significant reduction in revenues as a result of the pandemic. This is due to the delivery of gas and electricity being considered an essential service, with delivery to customers continuing in a timely manner with no delays or operational shutdowns taking place to date. To the extent that the pandemic does impact our ability to deliver in the future, operating revenues could be impacted. Currently, the impact of the pandemic to the collectability of our accounts receivable continues to be monitored, but such receivables have traditionally been included in rate recovery (see Note 11).
ACCOUNTS RECEIVABLE AND ALLOWANCE FOR CREDIT LOSSES	ACCOUNTS RECEIVABLE AND ALLOWANCE FOR CREDIT LOSSES - Accounts receivable are carried at the amount owed by customers. Accounts receivable are recorded gross on the consolidated balance sheets with an allowance for credit losses shown as a separate line item titled Provision for Uncollectibles. Beginning January 1, 2020, an allowance for credit losses was established in accordance with ASC 326, Financial Instruments - Credit Losses , meaning accounts receivables and unbilled revenues are carried at net realizable value based on the allowance for credit loss model, which is based on management's best estimate of expected credit losses to reduce accounts receivable for amounts estimated to be uncollectible. These estimates are based on such data as our accounts receivable aging, collection experience, current and forecasted economic conditions and an assessment of the collectibility of specific accounts. See Note 7.
NATURAL GAS IN STORAGE	NATURAL GAS IN STORAGE – Natural Gas in Storage is reflected at average cost on the consolidated balance sheets, and represents natural gas that will be utilized in the ordinary course of business.
ARO	ARO - The amounts included under ARO are primarily related to the legal obligations of SJI and SJG to cut and cap gas distribution pipelines when taking those pipelines out of service in future years. These liabilities are generally recognized upon the acquisition or construction of the asset, or when management has sufficient information to make an estimate of the obligation. The related asset retirement cost is capitalized concurrently by increasing the carrying amount of the related asset by the same amount as the liability and is depreciated over the remaining life of the related asset. Changes in the liability are recorded for the passage of time (accretion) or for revisions to cash flows originally estimated to settle the ARO.
PROPERTY, PLANT AND EQUIPMENT	PROPERTY, PLANT AND EQUIPMENT - For regulatory purposes, utility plant is stated at original cost, which may be different than costs if the assets were acquired from an unregulated entity. Nonutility property, plant and equipment is stated at cost. The cost of adding, replacing and renewing property is charged to the appropriate plant account.
DEPRECIATION	DEPRECIATION - We depreciate utility plant on a straight-line basis over the estimated remaining lives of the various property classes. These estimates are periodically reviewed and adjusted as required after BPU approval. The composite annual rate for all SJG depreciable utility property was approximately 2.4% in 2021, 2.5% in 2020, and 2.2% in 2019. The composite rate for all ETG depreciable utility property was approximately 2.5% in 2021, 2.3% in 2020, and 2.4% in 2019. The actual composite rate may differ from the approved rate as the asset mix changes over time. Except for retirements outside of the normal course of business, accumulated depreciation is charged with the cost of depreciable utility property retired, less salvage. All solar and fuel cell assets are included in Nonutility Property, Plant & Equipment on the consolidated balance sheets. Depreciation for solar assets is computed on a straight-line basis over the estimated useful lives of the assets, which range from 20 to 35 years depending on the length of underlying project contracts. All other nonutility property depreciation is computed on a straight-line basis over the estimated useful lives of the property, ranging up to 15 years. Gain or loss on the disposition of nonutility property is recognized in operating income.
CAPITALIZED SOFTWARE COSTS	CAPITALIZED SOFTWARE COSTS - For implementation costs incurred in a cloud computing arrangement that is a service contract, SJI and SJG capitalize certain costs incurred during the application-development and post-implementation-operation stages (provided the costs result in enhanced functionality to the hosted solution) in accordance with ASC 350-40. These costs are amortized over the life of the cloud computing arrangement. All other costs that do not meet the capitalization criteria per ASC 350-40 are expensed as incurred.
LEASES	LEASES - SJI, directly and through certain of its subsidiaries, including SJG, is a lessee of real estate (land and building), fleet vehicles, and office equipment. The Company evaluates its contracts at the lease inception date for the purpose of determining whether the contract is, or contains, a lease on the basis of whether or not the contract grants the Company the use of a specifically identified asset for a period of time, as well as whether the contract grants the Company both the right to direct the use of that asset and receive substantially all of the economic benefits from the use of the asset. We measure the right-of-use asset and lease liability at the present value of future lease payments excluding variable payments based on usage or performance. The majority of our leases are comprised of fixed lease payments, with a portion of the Company’s real estate, fleet vehicles, and office equipment leases including lease payments tied to levels of production, maintenance and property taxes, which may be subject to variability. Variable lease costs not included in the measurement of the lease are presented and disclosed as variable lease cost. We also evaluate contracts in which we are the owner of an underlying asset in the same manner as if it was a lease, to determine if we should be considered the lessor of that asset. The discount rate used to classify and measure a lease where SJI is a lessee is the rate implicit in the lease unless that rate cannot be readily determinable. In that case, the Company uses its incremental borrowing rate which is a lease-specific secured borrowing rate that factors in SJI’s credit standing and the lease term. SJI uses its incremental borrowing rate as the rate implicit in its leases is not readily determinable, except for the related party lease with SJG as discussed in Note 9. When measuring a lease, we include options to extend a lease in the lease term when it is reasonably certain that the option will be exercised and exclude all options to terminate the lease when it is reasonably certain that the option will not be exercised. When determining if a renewal option is reasonably certain of being exercised, the Company considers several economic factors, including the significance of leasehold improvements incurred on the property, whether the asset is difficult to replace, underlying contractual obligations, or specific characteristics unique to that particular lease that would make it reasonably certain that we would exercise such option. The renewal options in the leases generally allow the Company to extend the lease for an additional period of between 1 and 5 years, with the exception of a lease agreement between SJI and SJG (see Note 9). Our lease agreements generally do not include restrictions, financial covenants or residual value guarantees. In addition, other than the intercompany lease between SJI and SJG (see Note 9), the Company has not entered into any related party leases. ASC 842 includes certain practical expedients for arrangements where we are a lessee. We have elected, for all asset classes, the practical expedient to not separate lease components (e.g., costs related to renting the property) from their related non-lease components (e.g., common area maintenance costs), resulting in accounting for them as a single lease component. We have similarly elected, for all asset classes, the balance sheet recognition exemption for all leases with a term of 12 months or less. ASC 842 defines a short-term lease as any lease with a term of 12 months or less which does not include a purchase option that is reasonably certain of being exercised. ASC 842 includes a balance sheet recognition exemption for short-term leases, which the Company has elected for all asset classes. The Company recognizes lease cost for short-term leases on a straight-line basis over the lease term.
DEBT ISSUANCE COSTS & DEBT DISCOUNTS	DEBT ISSUANCE COSTS & DEBT DISCOUNTS - Debt issuance costs and debt discounts are capitalized and amortized as interest expense on a basis which approximates the effective interest method over the term of the related debt, and are presented as a direct deduction from the carrying amount of the related debt. See Note 14 for total unamortized debt issuance costs and debt discounts that are recorded as a reduction to long-term debt on the consolidated balance sheets of SJI and SJG.
AFUDC & CAPITALIZED INTEREST	AFUDC & CAPITALIZED INTEREST - SJI and SJG record AFUDC, which represents the estimated debt and equity costs of capital funds that are necessary to finance the construction of new facilities, at the rate of return on the rate base utilized by the BPU to set rates in the Utilities' last base rate proceedings, and amounts are included in Utility Plant on the consolidated balance sheets. These capitalized interest amounts are included in all plant categories, including Construction Work In Progress, in the Utility Plant table above, based on the nature of the underlying projects that qualified for AFUDC and each project's in-service status. For SJG's accelerated infrastructure programs and ETG's infrastructure investment programs, SJG and ETG record AFUDC at a rate prescribed by the programs which are discussed in Note 10. While cash is not realized currently, AFUDC increases the regulated revenue requirement and is included in rate base and recovered over the service life of the asset through a higher rate base and higher depreciation.
DERIVATIVE INSTRUMENTS	DERIVATIVE INSTRUMENTS - SJI accounts for derivative instruments in accordance with ASC 815, Derivatives and Hedging . We record all derivatives, whether designated in hedging relationships or not, on the consolidated balance sheets at fair value unless the derivative contracts qualify for the normal purchase and sale exemption. In general, if the derivative is designated as a fair value hedge, we recognize the changes in the fair value of the derivative and of the hedged item attributable to the hedged risk in earnings. SJI and SJG have no fair value or cash flow hedges. We formally document all relationships between hedging instruments and hedged items, as well as our risk management objectives, strategies for undertaking various hedge transactions and our methods for assessing and testing correlation and hedge ineffectiveness. All hedging instruments are linked to the hedged asset, liability, firm commitment or forecasted transaction. Due to the application of regulatory accounting principles under ASC 980, gains and losses on derivatives related to SJG's and ETG's gas purchases are recorded through the BGSS clause. Initially and on an ongoing basis, we assess whether derivatives designated as hedges are highly effective in offsetting changes in cash flows or fair values of the hedged items. We discontinue hedge accounting prospectively if we decide to discontinue the hedging relationship; determine that the anticipated transaction is no longer likely to occur; or determine that a derivative is no longer highly effective as a hedge. In the event that hedge accounting is discontinued, we will continue to carry the derivative on the balance sheet at its current fair value and recognize subsequent changes in fair value in current period earnings. Unrealized gains and losses on the discontinued hedges that were previously included in AOCL will be reclassified into earnings when the forecasted transaction occurs, or when it is probable that it will not occur. Hedge accounting has been discontinued for all remaining derivatives that were designated as hedging instruments. As a result, unrealized gains and losses on these derivatives, that were previously recorded in AOCL on the consolidated balance sheets, are being recorded into earnings over the remaining lives of the derivative contracts.
TREASURY STOCK	TREASURY STOCK – SJI uses the par value method of accounting for treasury stock.
INCOME TAXES	INCOME TAXES - Deferred income taxes are provided for all significant temporary differences between the book and taxable bases of assets and liabilities in accordance with ASC 740, Income Taxes (see Note 4). Certain deferred income taxes are recorded with offsetting regulatory assets or liabilities by the Company to recognize that income taxes will be recovered or refunded through future rates. A valuation allowance is recorded when it is more likely than not that any of SJI's or SJG's deferred tax assets will not be realized (see Note 4).
CASH AND CASH EQUIVALENTS	CASH AND CASH EQUIVALENTS - For purposes of reporting cash flows, highly liquid investments with original maturities of three months or less are considered cash equivalents.
ACQUISITION ACCOUNTING	ACQUISITION ACCOUNTING - At the time of an acquisition, management will assess whether acquired assets and activities meet the definition of a business. If the definition of a business is met, the Company accounts for the acquisition as a business combination and applies the acquisition method. Operating results from the date of acquisition are included in the acquiring entity's financial statements. The consideration transferred for an acquisition is the fair value of the assets transferred, the liabilities incurred or assumed by the acquirer and the equity interests issued by the acquirer. Identifiable assets acquired and liabilities and contingent liabilities assumed in a business combination are measured initially at their fair values at the acquisition date. The excess of the consideration transferred over the fair value of the identifiable net assets acquired is recorded as goodwill. Assets acquired that do not meet the definition of a business are accounted for as an asset acquisition. The purchase price of each asset acquisition is allocated based on the relative fair value of assets acquired. Determining the fair value of assets acquired and liabilities assumed requires judgment. Fair values are determined by using market participant assumptions and typically include the timing and amounts of future cash flows, incurred construction costs, the nature of acquired contracts, discount rates, and expected asset lives. Acquisition-related costs are expensed as incurred. See Note 20.
COMPREHENSIVE INCOME	COMPREHENSIVE INCOME - This measures all changes in common stock equity that result from transactions and events other than transactions with owners. Comprehensive income consists of net income attributable to the Company, changes in the fair value of qualifying hedges, and certain changes in pension and other postretirement benefit plans. SJI and SJG release income tax effects from AOCL on an individual unit of account basis.
NEW ACCOUNTING PRONOUNCEMENTS	NEW ACCOUNTING PRONOUNCEMENTS - Recently Adopted Standards: Standard Description Date of Adoption Application Effect on the Financial Statements of SJI and SJG ASU 2019-12: This ASU removes exceptions related to the incremental approach for intraperiod tax allocation, the requirement to recognize a deferred tax liability for changes in ownership of a foreign subsidiary or equity method investment, and the general methodology for calculating income taxes in an interim period when the year-to-date loss exceeds the anticipated loss. The guidance also adds requirements to reflect changes to tax laws or rates in the annual effective tax rate computation in the interim period in which the changes were enacted, to recognize franchise or other similar taxes that are partially based on income as an income-based tax and any incremental amounts as non-income-based tax, and to evaluate when a step-up in the tax basis of goodwill should be considered part of the business combination in which the book goodwill was originally recognized and when it should be considered a separate transaction. January 1, 2021 Modified retrospective for amendments related to changes in ownership of a foreign subsidiary or equity method investment; Modified retrospective or retrospective for amendments related to taxes partially based on income; Prospective for all other amendments Adoption of this guidance did not have a material impact on the financial statement results of SJI or SJG. ASU 2020-01: The amendments in this ASU clarify that an entity should consider observable transactions that require it to either apply or discontinue the equity method of accounting for the purposes of applying the measurement alternative in accordance with Topic 321 immediately before applying or upon discontinuing the equity method. The amendments in this ASU also clarify that, for the purposes of applying Topic 815, an entity should not consider whether, upon the settlement of a forward contract or exercise of a purchased option, individually or with existing investments, the underlying securities would be accounted for under the equity method in Topic 323 or the fair value option in accordance with the financial instruments guidance in Topic 825. January 1, 2021 Prospective Adoption of this guidance did not have a material impact on the financial statement results of SJI or SJG. Standards Not Yet Effective: Standard Description Date of Adoption Application Effect on the Financial Statements of SJI and SJG ASU 2020-04: ASU 2021-01: Reference Rate Reform (Topic 848) The amendments in ASU 2020-04 provide various optional expedients and exceptions for applying GAAP to contracts, hedging relationships, and other transactions affected by reference rate reform if certain criteria are met. The amendments apply only to contracts, hedging relationships, and other transactions that reference LIBOR or another reference rate expected to be discontinued because of reference rate reform. The expedients and exceptions provided by the amendments do not apply to contract modifications made and hedging relationships entered into or evaluated after December 31, 2022, except for hedging relationships existing as of December 31, 2022, that an entity has elected certain optional expedients for and that are retained through the end of the hedging relationship. The amendments in ASU 2021-01 clarify that certain optional expedients and exceptions in Topic 848 for contract modifications and hedge accounting apply to changes in the interest rates used for margining, discounting, or contract price alignment for derivative instruments that are being implemented as part of the market-wide transition to new reference rates (commonly referred to as the "discounting transition"). March 12, 2020 through December 31, 2022 An entity may elect to apply the amendments for contract modifications by Topic or Industry Subtopic as of any date from the beginning of an interim period that includes or is subsequent to March 12, 2020, or prospectively from a date within an interim period that includes or is subsequent to March 12, 2020, up to the date that the financial statements are available to be issued. Prospective for contract modifications and hedging relationships. Once elected for a Topic or an Industry Subtopic, the amendments in this Update must be applied prospectively for all eligible contract modifications for that Topic or Industry Subtopic. Management does not expect adoption of this guidance to have a material impact on the financial statements of SJI and SJG. Management will adopt the new guidance effective January 1, 2022. ASU 2020-06: Accounting for Convertible Instruments and Contracts in an Entity's Own Equity The amendments in this ASU simplify the accounting for convertible instruments by removing certain separation models in Subtopic 470-20. Under the amendments, embedded conversion features are no longer separated from the host contract for convertible instruments with conversion features that are not required to be accounted for as derivatives under Topic 815, or that do not result in substantial premiums accounted for as paid-in capital. Consequently, a convertible debt instrument will be accounted for as a single liability measured at its amortized cost and a convertible preferred stock will be accounted for as a single equity instrument measured at its historical cost, as long as no other features require bifurcation and recognition as derivatives. The amendments also add new convertible instrument disclosure requirements. Additionally, the amendments in this ASU remove certain conditions from the settlement guidance within the derivative scope exception guidance contained in Subtopic 815-40 and further clarify the derivative scope exception guidance. Finally, the amendments in this ASU align the diluted EPS calculation for convertible instruments by requiring that an entity use the if-converted method instead of the treasury stock method when calculated diluted EPS for convertible instruments. January 1, 2022; early adoption permitted, but not before January 1, 2021 Retrospective or Modified Retrospective Management does not expect adoption of this guidance to have a material impact on the financial statements of SJI and SJG. ASU 2021-08: Business Combinations (ASC 805): Accounting for Contract Assets and Contract Liabilities From Contracts With Customers The amendments to ASC 805 in this ASU require an acquirer to account for revenue contracts acquired in a business combination in accordance with ASC 606 as if it had originated the contracts. The acquirer may assess how the acquiree applied ASC 606 to determine what to record for the acquired contracts. The standard also provides practical expedients for acquirers when recognizing and measuring acquired contract assets and contract liabilities from a business combination. January 1, 2023; early adoption is permitted, including adoption in an interim period Prospectively to business combinations occurring on or after the effective date of the amendments These amendments have not yet been adopted and management is currently evaluating whether to adopt this amendment prior to the effective date. ASU 2021-10: Government Assistance (ASC 832): Disclosures by Business Entities about Government Assistance This ASU requires disclosure in the notes to annual financial statements of government financial assistance from local, (city, town, county, municipal), regional, and federal governments and entities related to those governments. Required disclosure for government assistance transactions includes: 1) information about the nature of transactions and the related accounting policy used to account for the transactions; 2) the line items on the balance sheet and income statement that are affected by the transactions and the amounts applicable to each financial statement line item; and 3) significant terms and conditions of the transactions, including commitments and contingencies. January 1, 2022; early adoption is permitted. Either (1) Prospectively to all transactions that are reflected in financial statements at the date of initial application and to all transactions that are entered into after adoption (2) retrospectively to those transactions Since this ASU is disclosure only, adoption will not have an impact on the financial statement results of SJI or SJG. Management is currently determining the impact that adoption of this guidance will have on the disclosures of SJI and SJG. Revenue Recognized Over Time: Reportable Segment Performance Obligation Description SJG Utility Operations ETG Utility Operations ELK Utility Operations Wholesale Energy Operations Natural Gas SJG, ETG and, prior to its sale in July 2020 (see Note 1), ELK, sell natural gas to residential, commercial and industrial customers, and price is based on regulated tariff rates which are established by the BPU or the MPSC, as applicable. There is an implied contract with a customer for the purchase, delivery, and sale of gas, and the customer is billed monthly, with payment due within 30 days. Payments are received from certain customers based on a predetermined budget billing schedule. Budget billing does not represent a contract asset or liability but rather just a receivable/liability because there are no further performance obligations required to be satisfied before the Utilities have the right to collect/refund the customer’s consideration. Consideration is due when control of the energy is transferred to the customer and is satisfied with the passage of time. Budget billing liability balances are recorded within the Customer Deposits and Credit Balances line item in the consolidated balance sheets. SJG has direct connections to and long-term gas transmission services on interstate pipeline systems. The sale of gas to third parties from these pipelines prior to entering our service territory is considered OSS. These contracts to sell off-system are at a price, quantity and time period agreed to by both parties determined on a contract by contract basis. SJRG sells natural gas to commercial customers at either a fixed quantity or at variable quantities based on a customer's needs. Payment is due on the 25th of each month for the previous month's deliveries. Revenue is currently being recognized over time based upon volumes delivered (i.e., unit of output) or through the passage of time ratably as the customer uses natural gas, which represents satisfaction of the performance obligation. SJG Utility Operations Wholesale Energy Operations Pipeline Transportation Capacity SJG and SJRG sell pipeline transportation capacity on a wholesale basis to various customers on the interstate pipeline system and transport natural gas purchased directly from producers or suppliers to their customers (for SJG, this is known as Capacity Release). These contracts to sell this capacity are at a price, quantity and time period agreed to by both parties determined on a contract by contract basis. Payment is due on the 25th of each month for the previous month's deliveries. Revenue is currently being recognized over time based upon volumes delivered (i.e., unit of output) or through the passage of time ratably coinciding with the delivery of gas and the customer obtaining control, which represents satisfaction of the performance obligation. Wholesale Energy Operations Fuel Management Services SJRG currently has several fuel supply management contracts where SJRG has acquired pipeline transportation capacity that allows SJRG to match end users, many of which are merchant generators, with producers looking to find a long-term solution for their supply. Natural gas is sold to the merchant generator daily based on its needs, with payment made either weekly or biweekly depending on the contract. Revenue is currently being recognized over time based upon volumes delivered (i.e., unit of output) coinciding with the delivery of gas and the customer obtaining control, which represents satisfaction of the performance obligation. Retail Services Electricity SJE sells electricity to commercial, industrial and residential customers at fixed prices throughout the life of the contract, with the customer billed monthly and payment due within 30 days. Revenue is currently being recognized over time based upon volumes delivered (i.e., unit of output) or through the passage of time ratably coinciding with the delivery of electricity and the customer obtaining control, which represents satisfaction of the performance obligation. Renewables Solar Solar projects earn revenue based on electricity generated. The customer is billed monthly as electricity is being generated, with payment due within 30 days. The performance obligation is satisfied as kilowatt hours of energy are generated (i.e., unit of output), which is when revenue is recognized. Renewables Fuel Cell The fuel cell projects earn revenue based on electricity generated. The customer is billed monthly as electricity is being generated, with payment due within 30 days. The performance obligation is satisfied as kilowatt hours of energy are generated (i.e., unit of output), which is when revenue is recognized. Renewables CHP Marina sold MTF/ACB in February 2020 (see Note 1). Prior to its sale, Marina had a contract with a casino and resort in Atlantic City, NJ to provide cooling, heating and emergency power. There were multiple performance obligations with this contract, including electric, chilled water and hot water, and each of these was considered distinct and separately identifiable performance obligations that were all priced separately. These performance obligations were satisfied over time ratably as they were used by the customer, who was billed monthly. Retail Services Energy Procurement Consulting Services AEP and EnerConnex provide energy procurement consulting services. These businesses match energy suppliers with end users and are paid commissions by energy suppliers. The commissions received on energy procurement contracts (whether received at the beginning of a contract or paid under monthly terms) are earned and recognized over the duration of the underlying contracts as energy usage occurs, which represents satisfaction of the performance obligation. The resulting contract liabilities are not material as of December 31, 2021, 2020 and 2019. Revenue Recognized at a Point in Time: Reportable Segment Performance Obligation Description Renewables SRECs The customer is billed based on a contracted amount of SRECs to be sold, with the price based on the market price of the SRECs at the time of generation. This does not represent variable consideration as the price is known and established at the time of generation and delivery to the customer. The performance obligation is satisfied at the point in time the SREC is delivered to the customer, which is when revenue is recognized. Payment terms are approximately 10 days subsequent to delivery.
FAIR VALUE	GAAP establishes a hierarchy that prioritizes fair value measurements based on the types of inputs used for the various valuation techniques. The levels of the hierarchy are described below: • Level 1: Observable inputs, such as quoted prices in active markets for identical assets or liabilities. • Level 2: Inputs other than quoted prices that are observable for the asset or liability, either directly or indirectly; these include quoted prices for similar assets or liabilities in active markets and quoted prices for identical or similar assets or liabilities in markets that are not active. • Level 3: Unobservable inputs that reflect the reporting entity’s own assumptions. Assessment of the significance of a particular input to the fair value measurement requires judgment and may affect the valuation of financial assets and financial liabilities and their placement within the fair value hierarchy. (A) Available-for-Sale Securities include securities that are traded in active markets and securities that are not traded publicly. The securities traded in active markets are valued using the quoted principal market close prices that are provided by the trustees and are categorized in Level 1 in the fair value hierarchy. (B) Derivatives – Energy Related Assets and Liabilities are traded in both exchange-based and non-exchange-based markets. Exchange-based contracts are valued using unadjusted quoted market sources in active markets and are categorized in Level 1 in the fair value hierarchy. Certain non-exchange-based contracts are valued using indicative price quotations available through brokers or over-the-counter, on-line exchanges and are categorized in Level 2. These price quotations reflect the average of the bid-ask mid-point prices and are obtained from sources that management believes provide the most liquid market. Management reviews and corroborates the price quotations with at least one additional source to ensure the prices are observable market information, which includes consideration of actual transaction volumes, market delivery points, bid-ask spreads and contract duration. For non-exchange-based derivatives that trade in less liquid markets with limited pricing information, model inputs generally would include both observable and unobservable inputs. In instances where observable data is unavailable, management considers the assumptions that market participants would use in valuing the asset or liability. This includes assumptions about market risks such as liquidity, volatility and contract duration. Such instruments are categorized in Level 3 in the fair value hierarchy as the model inputs generally are not observable. Management uses the discounted cash flow model to value Level 3 physical and financial forward contracts, which calculates mark-to-market valuations based on forward market prices, original transaction prices, volumes, risk-free rate of return and credit spreads. Inputs to the valuation model are reviewed and revised as needed, based on historical information, updated market data, market liquidity and relationships, and changes in third party pricing sources. The validity of the mark-to-market valuations and changes in these values from period to period are examined and qualified against historical expectations by the risk management function. If any discrepancies are identified during this process, the mark-to-market valuations or the market pricing information is evaluated further and adjusted, if necessary.

Schedule of New Accounting Pronouncements	NEW ACCOUNTING PRONOUNCEMENTS - Recently Adopted Standards: Standard Description Date of Adoption Application Effect on the Financial Statements of SJI and SJG ASU 2019-12: This ASU removes exceptions related to the incremental approach for intraperiod tax allocation, the requirement to recognize a deferred tax liability for changes in ownership of a foreign subsidiary or equity method investment, and the general methodology for calculating income taxes in an interim period when the year-to-date loss exceeds the anticipated loss. The guidance also adds requirements to reflect changes to tax laws or rates in the annual effective tax rate computation in the interim period in which the changes were enacted, to recognize franchise or other similar taxes that are partially based on income as an income-based tax and any incremental amounts as non-income-based tax, and to evaluate when a step-up in the tax basis of goodwill should be considered part of the business combination in which the book goodwill was originally recognized and when it should be considered a separate transaction. January 1, 2021 Modified retrospective for amendments related to changes in ownership of a foreign subsidiary or equity method investment; Modified retrospective or retrospective for amendments related to taxes partially based on income; Prospective for all other amendments Adoption of this guidance did not have a material impact on the financial statement results of SJI or SJG. ASU 2020-01: The amendments in this ASU clarify that an entity should consider observable transactions that require it to either apply or discontinue the equity method of accounting for the purposes of applying the measurement alternative in accordance with Topic 321 immediately before applying or upon discontinuing the equity method. The amendments in this ASU also clarify that, for the purposes of applying Topic 815, an entity should not consider whether, upon the settlement of a forward contract or exercise of a purchased option, individually or with existing investments, the underlying securities would be accounted for under the equity method in Topic 323 or the fair value option in accordance with the financial instruments guidance in Topic 825. January 1, 2021 Prospective Adoption of this guidance did not have a material impact on the financial statement results of SJI or SJG. Standards Not Yet Effective: Standard Description Date of Adoption Application Effect on the Financial Statements of SJI and SJG ASU 2020-04: ASU 2021-01: Reference Rate Reform (Topic 848) The amendments in ASU 2020-04 provide various optional expedients and exceptions for applying GAAP to contracts, hedging relationships, and other transactions affected by reference rate reform if certain criteria are met. The amendments apply only to contracts, hedging relationships, and other transactions that reference LIBOR or another reference rate expected to be discontinued because of reference rate reform. The expedients and exceptions provided by the amendments do not apply to contract modifications made and hedging relationships entered into or evaluated after December 31, 2022, except for hedging relationships existing as of December 31, 2022, that an entity has elected certain optional expedients for and that are retained through the end of the hedging relationship. The amendments in ASU 2021-01 clarify that certain optional expedients and exceptions in Topic 848 for contract modifications and hedge accounting apply to changes in the interest rates used for margining, discounting, or contract price alignment for derivative instruments that are being implemented as part of the market-wide transition to new reference rates (commonly referred to as the "discounting transition"). March 12, 2020 through December 31, 2022 An entity may elect to apply the amendments for contract modifications by Topic or Industry Subtopic as of any date from the beginning of an interim period that includes or is subsequent to March 12, 2020, or prospectively from a date within an interim period that includes or is subsequent to March 12, 2020, up to the date that the financial statements are available to be issued. Prospective for contract modifications and hedging relationships. Once elected for a Topic or an Industry Subtopic, the amendments in this Update must be applied prospectively for all eligible contract modifications for that Topic or Industry Subtopic. Management does not expect adoption of this guidance to have a material impact on the financial statements of SJI and SJG. Management will adopt the new guidance effective January 1, 2022. ASU 2020-06: Accounting for Convertible Instruments and Contracts in an Entity's Own Equity The amendments in this ASU simplify the accounting for convertible instruments by removing certain separation models in Subtopic 470-20. Under the amendments, embedded conversion features are no longer separated from the host contract for convertible instruments with conversion features that are not required to be accounted for as derivatives under Topic 815, or that do not result in substantial premiums accounted for as paid-in capital. Consequently, a convertible debt instrument will be accounted for as a single liability measured at its amortized cost and a convertible preferred stock will be accounted for as a single equity instrument measured at its historical cost, as long as no other features require bifurcation and recognition as derivatives. The amendments also add new convertible instrument disclosure requirements. Additionally, the amendments in this ASU remove certain conditions from the settlement guidance within the derivative scope exception guidance contained in Subtopic 815-40 and further clarify the derivative scope exception guidance. Finally, the amendments in this ASU align the diluted EPS calculation for convertible instruments by requiring that an entity use the if-converted method instead of the treasury stock method when calculated diluted EPS for convertible instruments. January 1, 2022; early adoption permitted, but not before January 1, 2021 Retrospective or Modified Retrospective Management does not expect adoption of this guidance to have a material impact on the financial statements of SJI and SJG. ASU 2021-08: Business Combinations (ASC 805): Accounting for Contract Assets and Contract Liabilities From Contracts With Customers The amendments to ASC 805 in this ASU require an acquirer to account for revenue contracts acquired in a business combination in accordance with ASC 606 as if it had originated the contracts. The acquirer may assess how the acquiree applied ASC 606 to determine what to record for the acquired contracts. The standard also provides practical expedients for acquirers when recognizing and measuring acquired contract assets and contract liabilities from a business combination. January 1, 2023; early adoption is permitted, including adoption in an interim period Prospectively to business combinations occurring on or after the effective date of the amendments These amendments have not yet been adopted and management is currently evaluating whether to adopt this amendment prior to the effective date. ASU 2021-10: Government Assistance (ASC 832): Disclosures by Business Entities about Government Assistance This ASU requires disclosure in the notes to annual financial statements of government financial assistance from local, (city, town, county, municipal), regional, and federal governments and entities related to those governments. Required disclosure for government assistance transactions includes: 1) information about the nature of transactions and the related accounting policy used to account for the transactions; 2) the line items on the balance sheet and income statement that are affected by the transactions and the amounts applicable to each financial statement line item; and 3) significant terms and conditions of the transactions, including commitments and contingencies. January 1, 2022; early adoption is permitted. Either (1) Prospectively to all transactions that are reflected in financial statements at the date of initial application and to all transactions that are entered into after adoption (2) retrospectively to those transactions Since this ASU is disclosure only, adoption will not have an impact on the financial statement results of SJI or SJG. Management is currently determining the impact that adoption of this guidance will have on the disclosures of SJI and SJG.

The effect of counterparty credit risk and the credit risk of SJI on the derivative valuations is not significant. (A) Available-for-Sale Securities include securities that are traded in active markets and securities that are not traded publicly. The securities traded in active markets are valued using the quoted principal market close prices that are provided by the trustees and are categorized in Level 1 in the fair value hierarchy. (B) Derivatives – Energy Related Assets and Liabilities are traded in both exchange-based and non-exchange-based markets. Exchange-based contracts are valued using unadjusted quoted market sources in active markets and are categorized in Level 1 in the fair value hierarchy. Certain non-exchange-based contracts are valued using indicative price quotations available through brokers or over-the-counter, on-line exchanges and are categorized in Level 2. These price quotations reflect the average of the bid-ask mid-point prices and are obtained from sources that management believes provide the most liquid market. Management reviews and corroborates the price quotations with at least one additional source to ensure the prices are observable market information, which includes consideration of actual transaction volumes, market delivery points, bid-ask spreads and contract duration. For non-exchange-based derivatives that trade in less liquid markets with limited pricing information, model inputs generally would include both observable and unobservable inputs. In instances where observable data is unavailable, management considers the assumptions that market participants would use in valuing the asset or liability. This includes assumptions about market risks such as liquidity, volatility and contract duration. Such instruments are categorized in Level 3 in the fair value hierarchy as the model inputs generally are not observable. Management uses the discounted cash flow model to value Level 3 physical and financial forward contracts, which calculates mark-to-market valuations based on forward market prices, original transaction prices, volumes, risk-free rate of return and credit spreads. Inputs to the valuation model are reviewed and revised as needed, based on historical information, updated market data, market liquidity and relationships, and changes in third party pricing sources. The validity of the mark-to-market valuations and changes in these values from period to period are examined and qualified against historical expectations by the risk management function. If any discrepancies are identified during this process, the mark-to-market valuations or the market pricing information is evaluated further and adjusted, if necessary.

Revenue from Contract with Customer [Abstract]
Revenue, Remaining Performance Obligation, Expected Timing of Satisfaction	Below is a listing of all performance obligations that arise from contracts with customers, along with details on the satisfaction of each performance obligation, the significant payment terms, and the nature of the goods and services being transferred: Revenue Recognized Over Time: Reportable Segment Performance Obligation Description SJG Utility Operations ETG Utility Operations ELK Utility Operations Wholesale Energy Operations Natural Gas SJG, ETG and, prior to its sale in July 2020 (see Note 1), ELK, sell natural gas to residential, commercial and industrial customers, and price is based on regulated tariff rates which are established by the BPU or the MPSC, as applicable. There is an implied contract with a customer for the purchase, delivery, and sale of gas, and the customer is billed monthly, with payment due within 30 days. Payments are received from certain customers based on a predetermined budget billing schedule. Budget billing does not represent a contract asset or liability but rather just a receivable/liability because there are no further performance obligations required to be satisfied before the Utilities have the right to collect/refund the customer’s consideration. Consideration is due when control of the energy is transferred to the customer and is satisfied with the passage of time. Budget billing liability balances are recorded within the Customer Deposits and Credit Balances line item in the consolidated balance sheets. SJG has direct connections to and long-term gas transmission services on interstate pipeline systems. The sale of gas to third parties from these pipelines prior to entering our service territory is considered OSS. These contracts to sell off-system are at a price, quantity and time period agreed to by both parties determined on a contract by contract basis. SJRG sells natural gas to commercial customers at either a fixed quantity or at variable quantities based on a customer's needs. Payment is due on the 25th of each month for the previous month's deliveries. Revenue is currently being recognized over time based upon volumes delivered (i.e., unit of output) or through the passage of time ratably as the customer uses natural gas, which represents satisfaction of the performance obligation. SJG Utility Operations Wholesale Energy Operations Pipeline Transportation Capacity SJG and SJRG sell pipeline transportation capacity on a wholesale basis to various customers on the interstate pipeline system and transport natural gas purchased directly from producers or suppliers to their customers (for SJG, this is known as Capacity Release). These contracts to sell this capacity are at a price, quantity and time period agreed to by both parties determined on a contract by contract basis. Payment is due on the 25th of each month for the previous month's deliveries. Revenue is currently being recognized over time based upon volumes delivered (i.e., unit of output) or through the passage of time ratably coinciding with the delivery of gas and the customer obtaining control, which represents satisfaction of the performance obligation. Wholesale Energy Operations Fuel Management Services SJRG currently has several fuel supply management contracts where SJRG has acquired pipeline transportation capacity that allows SJRG to match end users, many of which are merchant generators, with producers looking to find a long-term solution for their supply. Natural gas is sold to the merchant generator daily based on its needs, with payment made either weekly or biweekly depending on the contract. Revenue is currently being recognized over time based upon volumes delivered (i.e., unit of output) coinciding with the delivery of gas and the customer obtaining control, which represents satisfaction of the performance obligation. Retail Services Electricity SJE sells electricity to commercial, industrial and residential customers at fixed prices throughout the life of the contract, with the customer billed monthly and payment due within 30 days. Revenue is currently being recognized over time based upon volumes delivered (i.e., unit of output) or through the passage of time ratably coinciding with the delivery of electricity and the customer obtaining control, which represents satisfaction of the performance obligation. Renewables Solar Solar projects earn revenue based on electricity generated. The customer is billed monthly as electricity is being generated, with payment due within 30 days. The performance obligation is satisfied as kilowatt hours of energy are generated (i.e., unit of output), which is when revenue is recognized. Renewables Fuel Cell The fuel cell projects earn revenue based on electricity generated. The customer is billed monthly as electricity is being generated, with payment due within 30 days. The performance obligation is satisfied as kilowatt hours of energy are generated (i.e., unit of output), which is when revenue is recognized. Renewables CHP Marina sold MTF/ACB in February 2020 (see Note 1). Prior to its sale, Marina had a contract with a casino and resort in Atlantic City, NJ to provide cooling, heating and emergency power. There were multiple performance obligations with this contract, including electric, chilled water and hot water, and each of these was considered distinct and separately identifiable performance obligations that were all priced separately. These performance obligations were satisfied over time ratably as they were used by the customer, who was billed monthly. Retail Services Energy Procurement Consulting Services AEP and EnerConnex provide energy procurement consulting services. These businesses match energy suppliers with end users and are paid commissions by energy suppliers. The commissions received on energy procurement contracts (whether received at the beginning of a contract or paid under monthly terms) are earned and recognized over the duration of the underlying contracts as energy usage occurs, which represents satisfaction of the performance obligation. The resulting contract liabilities are not material as of December 31, 2021, 2020 and 2019. Revenue Recognized at a Point in Time: Reportable Segment Performance Obligation Description Renewables SRECs The customer is billed based on a contracted amount of SRECs to be sold, with the price based on the market price of the SRECs at the time of generation. This does not represent variable consideration as the price is known and established at the time of generation and delivery to the customer. The performance obligation is satisfied at the point in time the SREC is delivered to the customer, which is when revenue is recognized. Payment terms are approximately 10 days subsequent to delivery.

(b) All unbilled revenue for SJI and SJG arises from contracts with customers. Unbilled revenue relates to SJI's and SJG's right to receive payment for commodity delivered but not yet billed. This represents contract assets that arise from contracts with customers, which is defined in ASC 606 as the right to payment in exchange for goods already transferred to a customer, excluding any amounts presented as a receivable. The unbilled revenue is transferred to accounts receivable when billing occurs and the rights to collection become unconditional.
