Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Note 2 — Summary of Significant Accounting Policies The accompanying condensed consolidated financial statements are unaudited and have been prepared in accordance with the rules and regulations of the SEC. They include all adjustments that we consider necessary for a fair statement of the results for the interim periods presented. Such adjustments consisted only of normal recurring items unless otherwise disclosed. The September 30, 2022, Condensed Consolidated Balance Sheet was derived from audited financial statements but does not include all footnote disclosures from the annual financial statements. These financial statements should be read in conjunction with the financial statements and related notes included in the Company’s 2022 Annual Report. Due to the seasonal nature of our businesses, the results of operations for interim periods are not necessarily indicative of the results to be expected for a full year. Restricted Cash. Restricted cash principally represents those cash balances in our commodity futures brokerage accounts that are restricted from withdrawal. The following table provides a reconciliation of the total cash, cash equivalents and restricted cash reported on the Condensed Consolidated Balance Sheets to the corresponding amounts reported on the Condensed Consolidated Statements of Cash Flows. March 31, March 31, Cash and cash equivalents $ 321 $ 718 Restricted cash 82 55 Cash, cash equivalents and restricted cash $ 403 $ 773 Earnings Per Common Share. Basic earnings per share attributable to UGI stockholders reflect the weighted-average number of common shares outstanding. Diluted earnings per share attributable to UGI stockholders include the effects of dilutive stock options, common stock awards and Equity Units. Shares used in computing basic and diluted earnings per share are as follows: Three Months Ended Six Months Ended 2023 2022 2023 2022 Denominator (thousands of shares): Weighted-average common shares outstanding — basic 209,857 210,163 209,902 209,919 Incremental shares issuable for stock options, common stock awards and Equity Units (a) 6,263 5,765 — 6,017 Weighted-average common shares outstanding — diluted 216,120 215,928 209,902 215,936 (a) For the three months ended March 31, 2023, 5,980 shares associated with outstanding stock option awards were excluded from the computation of diluted earnings per share because their effect was antidilutive. For the six months ended March 31, 2023, 6,348 of such shares have been excluded as such incremental shares would be antidilutive due to the net loss for the period. For the three and six months ended March 31, 2022, 6,535 shares associated with outstanding stock option awards were excluded from the computation of diluted earnings per share because their effect was antidilutive. Equity Method Investments. We account for privately held equity securities of entities without readily determinable fair values in which we do not have control, but have significant influence over operating and financial policies, under the equity method. These are included in "Other assets" on the Condensed Consolidated Balance Sheets. Equity method earnings are included in "Income from equity method investees" on the Condensed Consolidated Statements of Income. Our equity method investments primarily comprise MBL Bioenergy, Pine Run and other equity method investments in biomass and other renewable energy projects. MBL Bioenergy . The Company has an approximate 99.99% interest in MBL Bioenergy, a company jointly owned by UGI Dakota, LLC, Sevana Bioenergy and a subsidiary of California Bioenergy. The sole purpose of MBL Bioenergy is the development of RNG projects in South Dakota comprising three dairy waste anaerobic digester systems. MBL Bioenergy is a variable interest entity whereby the Company has determined that it is not the primary beneficiary since it does not direct the activities that most significantly impact the entity’s economic performance. The carrying value of our investment in MBL Bioenergy at March 31, 2023 and 2022 was $78 and $0, respectively. Pine Run. The Company has an approximately 49% interest in Pine Run, a company jointly owned by Stonehenge Energy Resources and UGI Pine Run LLC. Pine Run owns Pine Run Midstream which operates dry gas gathering pipelines and compression assets in western Pennsylvania. The carrying value of our investment in Pine Run at March 31, 2023 and 2022 was $72 and $65, respectively. Pennant . At March 31, 2022, the carrying value of our investment in Pennant was $97. During Fiscal 2022, UGI through Energy Services, completed the Pennant Acquisition in which Energy Services acquired the remaining 53% of the equity interests in Pennant. The acquisition of the remaining interests was accounted for as an acquisition of assets, and the purchase price of approximately $61 was primarily allocated to property, plant and equipment. Other Equity Method Investments . Our other equity method investments totaled $69 and $26 at March 31, 2023 and 2022, respectively, and principally comprise of a number of investments in biomass and other renewable energy projects at Midstream & Marketing and a renewable energy joint venture at UGI International. Our maximum exposure to loss related to these investments is limited to the amount invested. Derivative Instruments. Derivative instruments are reported on the Condensed Consolidated Balance Sheets at their fair values, unless the NPNS exception is elected. The accounting for changes in fair value depends upon the purpose of the derivative instrument, whether it is subject to regulatory ratemaking mechanisms or if it qualifies and is designated as a hedge for accounting purposes. Certain of our derivative instruments qualify and are designated as cash flow hedges. For cash flow hedges, changes in the fair values of the derivative instruments are recorded in AOCI, to the extent effective at offsetting changes in the hedged item, until earnings are affected by the hedged item. We discontinue cash flow hedge accounting if occurrence of the forecasted transaction is determined to be no longer probable. Hedge accounting is also discontinued for derivatives that cease to be highly effective. We do not designate our commodity and certain foreign currency derivative instruments as hedges under GAAP. Changes in the fair values of these derivative instruments are reflected in net income. Gains and losses on substantially all of the commodity derivative instruments used by Utilities are included in regulatory assets or liabilities because it is probable such gains or losses will be recoverable from, or refundable to, customers. From time to time, we also enter into net investment hedges. Gains and losses on net investment hedges that relate to our foreign operations are included in the cumulative translation adjustment component in AOCI until such foreign net investment is substantially sold or liquidated. Cash flows from derivative instruments, other than certain cross-currency swaps and net investment hedges, if any, are included in cash flows from operating activities on the Condensed Consolidated Statements of Cash Flows. Cash flows from the interest portion of our cross-currency hedges, if any, are included in cash flows from operating activities while cash flows from the currency portion of such hedges, if any, are included in cash flows from financing activities. Cash flows from net investment hedges, if any, are included in cash flows from investing activities on the Condensed Consolidated Statements of Cash Flows. For a more detailed description of the derivative instruments we use, our accounting for derivatives, our objectives for using them and other information, see Note 12. Use of Estimates. The preparation of financial statements in accordance with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues, expenses and costs. These estimates are based on management’s knowledge of current events, historical experience and various other assumptions that are believed to be reasonable under the circumstances. Accordingly, actual results may be different from these estimates and assumptions. Goodwill. We do not amortize goodwill, but test it at least annually for impairment at the reporting unit level. A reporting unit is an operating segment, or one level below an operating segment (a component) if it constitutes a business for which discrete financial information is available and regularly reviewed by segment management. Components are aggregated into a single reporting unit if they have similar economic characteristics. Each of our reporting units with goodwill is required to perform impairment tests annually or whenever events or circumstances indicate that the value of goodwill may be impaired. With respect to the AmeriGas Propane reporting unit’s Fiscal 2022 impairment test, we determined that AmeriGas Propane’s fair value exceeded its carrying value by approximately 30%. While the Company believes that the judgments used in that quantitative assessment of AmeriGas Propane’s fair value were reasonable based upon currently available facts and circumstances, if AmeriGas Propane were not able to achieve its anticipated results and/or if its weighted average cost of capital were to increase, its fair value would be adversely affected, which may result in an impairment. During the interim period ended March 31, 2023, AmeriGas Propane did not achieve its forecasted results and the weighted average cost of capital increased from the Fiscal 2022 impairment test. While these developments caused a decrease in the fair value of the AmeriGas Propane reporting unit, the Company has concluded that the decrease would not result in the carrying value of the reporting unit to exceed the estimated fair value. As a result, the Company has concluded that it is not more likely than not that the fair value of the AmeriGas Propane reporting unit is below its carrying amount as of March 31, 2023. There is approximately $2 billion of goodwill in this reporting unit as of March 31, 2023. The Company will continue to monitor its reporting units and related goodwill for any possible future non-cash impairment charges.

Accounting Changes and Error Corrections [Abstract]
Accounting Changes	Note 3 — Accounting Changes New Accounting Standard Adopted in Fiscal 2023 Debt and Derivatives and Hedging. Effective October 1, 2022, the Company adopted ASU 2020-06, “Debt - Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging – Contracts in Entity’s Own Equity (Subtopic 815-40).” The amendments in this ASU affect entities that issue convertible instruments and/or contracts indexed to and potentially settled in an entity’s own equity. This ASU reduces the number of accounting models for convertible debt instruments and convertible preferred stock, expands disclosure requirements for convertible instruments, and simplifies the related earnings per share guidance. We adopted this ASU using the modified retrospective transition method and applied the new guidance to applicable features of our Equity Units. Periods prior to October 1, 2022 have not been restated. Upon adoption, we reclassified $6 from Common Stock to Preferred Stock associated with the previously separated equity-classified beneficial conversion feature, which was accounted for as a deemed dividend. The increase to Preferred Stock was partially offset by an increase of $1 to opening retained earnings for the previously recognized non-cash amortization of the beneficial conversion feature. The ASU 2020-06 also removes the presumption of cash settlement for contracts that may be settled in cash or shares. In accordance with the new guidance, we included the dilutive impact of the quarterly contract adjustment payment liability associated with the 2024 Purchase Contracts, which may be settled in cash or shares, in our computation of weighted average diluted common shares outstanding. The adoption of the new guidance did not, and is not expected to, have a material impact on our consolidated financial statements.

Contract Balances The timing of revenue recognition may differ from the timing of invoicing to customers or cash receipts. Contract assets represent our right to consideration after the performance obligations have been satisfied when such right is conditioned on something other than the passage of time. Contract assets were not material for all periods presented. Substantially all of our receivables are unconditional rights to consideration and are included in “Accounts receivable” and, in the case of Utilities, “Accrued utility revenues” on the Condensed Consolidated Balance Sheets. Amounts billed are generally due within the following month. Contract liabilities arise when payment from a customer is received before the performance obligations have been satisfied and represent the Company’s obligations to transfer goods or services to a customer for which we have received consideration. The balances of contract liabilities were $126, $164 and $100 at March 31, 2023, September 30, 2022 and March 31, 2022, respectively, and are included in “Other current liabilities” and “Other noncurrent liabilities” on the Condensed Consolidated Balance Sheets. Revenues recognized for the six months ended March 31, 2023 and 2022, from the amounts included in contract liabilities at September 30, 2022 and 2021, were $119 and $112, respectively. Remaining Performance Obligations The Company excludes disclosures related to the aggregate amount of the transaction price allocated to certain performance obligations that are unsatisfied as of the end of the reporting period because these contracts have an initial expected term of one year or less, or we have a right to bill the customer in an amount that corresponds directly with the value of services provided to the customer to date. Certain contracts with customers at Midstream & Marketing and Utilities contain minimum future performance obligations through 2047 and 2053, respectively. At March 31, 2023, Midstream & Marketing and Utilities expect to record approximately $2.2 billion and $0.2 billion of revenues, respectively, related to the minimum future performance obligations over the remaining terms of the related contracts.

Business Combination and Asset Acquisition [Abstract]
Dispositions and Acquisition	Note 5 — Dispositions and Acquisition UGI International Energy Marketing Businesses Sale of U.K. Energy Marketing Business. On October 21, 2022, UGI International, through a wholly-owned subsidiary, sold its natural gas marketing business located in the U.K. for a net cash payment of $19 which includes certain working capital adjustments. In conjunction with the sale, during the first quarter of Fiscal 2023, the Company recorded a pre-tax loss of $215 ($151 after-tax) substantially all of which loss was due to the non-cash transfer of commodity derivative instruments associated with the business. At the date of closing of the sale, these commodity derivative instruments had a net carrying value of $206 which is attributable to net unrealized gains on such instruments. At September 30, 2022, these derivative instruments were classified as held for sale assets on the Condensed Consolidated Balance Sheet and a net carrying value of $276. The change in the carrying value of these derivative instruments between September 30, 2022 and October 21, 2022 resulted from changes in their fair values during that period. Other UGI International Energy Marketing Businesses. In November 2022, the Company announced that it expected to sign a definitive agreement during the first quarter of Fiscal 2023 to sell its energy marketing business in France. In December 2022, the Company announced that it no longer expected to sign a definitive agreement during the first quarter of Fiscal 2023 as extended negotiations with the potential buyer had been discontinued. The Company continues to pursue the sale of its energy marketing business in France, as well as the wind-down of its energy marketing business located in Belgium and the Netherlands. At March 31, 2023, the sale of our energy marketing business in France was not considered probable of occurring within one year and, as such, assets and liabilities associated with this business were not classified as held for sale on the Condensed Consolidated Balance Sheet. During the first quarter of Fiscal 2023, the Company recorded a $19 pre-tax impairment charge to reduce the carrying values of certain assets associated with its energy marketing business in the Netherlands, comprising property, plant and equipment and intangible assets. The impairment charge is reflected in “Operating and administrative expenses” on the Condensed Consolidated Statement of Income and included in the UGI International segment. Acquisitions of Assets Stonehenge . On January 27, 2022, UGI, through Energy Services, completed the Stonehenge Acquisition in which Energy Services acquired all of the equity interests in Stonehenge for total cash consideration of approximately $190. The Stonehenge business includes a natural gas gathering system, located in western Pennsylvania, with more than 47 miles of pipeline and associated compression assets. The Stonehenge Acquisition is consistent with our growth strategies, including expanding our midstream natural gas gathering assets within the Appalachian basin production region. The Stonehenge Acquisition was funded using available cash. This transaction has been accounted for as an acquisition of assets, and the purchase price has been primarily allocated to property, plant and equipment. We refer to Stonehenge and its assets as “UGI Moraine East.”

Utility Regulatory Assets and Liabilities and Regulatory Matters	Note 7 — Utility Regulatory Assets and Liabilities and Regulatory Matters For a description of the Company’s regulatory assets and liabilities, other than those described below, see Note 9 in the Company’s 2022 Annual Report. Other than removal costs, Utilities currently does not recover a rate of return on its regulatory assets listed below. The following regulatory assets and liabilities associated with Utilities are included on the Condensed Consolidated Balance Sheets: March 31, September 30, March 31, Regulatory assets (a): Income taxes recoverable $ 94 $ 83 $ 148 Underfunded pension plans 118 114 104 Environmental costs 34 37 55 Deferred fuel and power costs 38 32 6 Removal costs, net 22 22 22 Other 53 52 49 Total regulatory assets $ 359 $ 340 $ 384 Regulatory liabilities (a): Postretirement benefit overcollections $ 10 $ 11 $ 12 Deferred fuel and power refunds 28 3 17 State tax benefits — distribution system repairs 39 38 34 Excess federal deferred income taxes 262 279 283 Other 6 4 14 Total regulatory liabilities $ 345 $ 335 $ 360 (a) Current regulatory assets are included in “Prepaid expenses and other current assets” and regulatory liabilities are included in “Other current liabilities” and “Other noncurrent liabilities” on the Condensed Consolidated Balance Sheets. Deferred fuel and power - costs and refunds. Utilities’ tariffs contain clauses that permit recovery of all prudently incurred purchased gas and power costs through the application of PGC rates, PGA rates and DS tariffs. These clauses provide for periodic adjustments to PGC, PGA and DS rates for differences between the total amount of purchased gas and electric generation supply costs collected from customers and recoverable costs incurred. Net undercollected costs are classified as a regulatory asset and net overcollections are classified as a regulatory liability. The WVPSC, in an effort to mitigate the impact of WV Gas Utility’s 2022 PGA rate increase to customers, delayed the effective date in 2022 from November 1 to December 1 and deferred $12 of unrecovered gas costs in determining the rates to be charged to the various customer classes effective December 1, 2022. Additionally, in order to lower winter bills for residential customers, the WVPSC removed transportation and storage costs from the volumetric rate and created a fixed monthly pipeline demand charge applicable only to residential customers. On April 12, 2023, the WVPSC issued a final Order that increased the PGA rate, which included the unrecovered gas cost balance initially deferred in the interim order, and continued the fixed monthly demand charge for residential customers. PA Gas Utility uses derivative instruments to reduce volatility in the cost of gas it purchases for retail core-market customers. Realized and unrealized gains or losses on natural gas derivative instruments are included in deferred fuel and power costs or refunds. Net unrealized (losses) gains on such contracts at March 31, 2023, September 30, 2022 and March 31, 2022 were $(17), $5 and $21, respectively. Other Regulatory Matters UGI Utilities. On January 27, 2023, Electric Utility filed a request with the PAPUC to increase its annual base distribution revenues by $11. The increased revenues would fund ongoing system improvements and operations necessary to maintain safe and reliable electric service. Electric Utility requested that the new electric rates become effective March 28, 2023. The PAPUC issued an Order on March 2, 2023, suspending the effective date for the rate increase to allow for investigation and public hearings. Unless a settlement is reached sooner, this review process is expected to last up to nine months from the date of filing. The Company cannot predict the timing or the ultimate outcome of the rate case review process. On January 28, 2022, PA Gas Utility filed a request with the PAPUC to increase its base operating revenues for residential, commercial and industrial customers by $83 annually. On September 15, 2022, the PAPUC issued a final order approving a settlement providing for a $49 annual base distribution rate increase for PA Gas Utility, through a phased approach, with $38 beginning October 29, 2022 and an additional $11 beginning October 1, 2023. In accordance with the terms of the final order, PA Gas Utility will not be permitted to file a rate case prior to January 1, 2024. Also in accordance with the terms of the final order, PA Gas Utility was authorized to implement a weather normalization adjustment rider as a five-year pilot program beginning on November 1, 2022. Under this rider, when weather deviates from normal by more than 3%, residential and small commercial customer billings for distribution services are adjusted monthly for weather related impacts exceeding the 3% threshold. Additionally, under the terms of the final order, PA Gas Utility was authorized to implement a DSIC once its total property, plant and equipment less accumulated depreciation reached $3,368 (which threshold was achieved in September 2022). On February 8, 2021, Electric Utility filed a request with the PAPUC to increase its annual base distribution revenues by $9. On October 28, 2021, the PAPUC issued a final Order approving a settlement that permitted Electric Utility, effective November 9, 2021, to increase its base distribution revenues by $6. Mountaineer. On March 6, 2023, Mountaineer submitted a base rate case filing with the WVPSC seeking a net revenue increase of $20, which consists of an increase in base rates of $38 and a decrease in the IREP rates of $18 annually to be effective on April 5, 2023. On March 31, 2023 the WVPSC suspended the effective date of the requested rate change increase until January 1, 2024 to allow for a full review of the filing.

Debt Disclosure [Abstract]
Debt	Note 8 — Debt AmeriGas Propane . Under the 2022 AmeriGas OLP Credit Agreement, AmeriGas OLP, as borrower, is required to comply with financial covenants related to leverage and interest coverage measured at the Partnership and at AmeriGas OLP. The 2022 AmeriGas OLP Credit Agreement contains an equity cure provision, which allows AmeriGas OLP’s direct or indirect parent, including UGI and its other subsidiaries, to fund capital contributions to eliminate any EBITDA (as defined in the 2022 AmeriGas OLP Credit Agreement) shortfalls that would otherwise result in non-compliance with these financial covenants. Each equity cure is eligible to eliminate such EBITDA shortfalls up to four quarters after contribution. We are permitted to use the equity cure provision five times over the course of the Credit Agreement, twice during any rolling four-quarter period, and not in consecutive quarters. As of March 31, 2023, AmeriGas OLP was in breach of the leverage ratio debt covenant and interest coverage ratio, which it cured with the funds received from UGI. UGI made capital contributions to AmeriGas OLP of $20 and $11 on March 31, 2023 and April 24, 2023, respectively, which in aggregate represented one equity cure in accordance with the 2022 AmeriGas OLP Credit Agreement. As a result of these capital contributions, AmeriGas OLP and the Partnership were in compliance with all financial covenants after consideration of the equity cure provision as of March 31, 2023. UGI also provided an irrevocable letter of support, dated May 4, 2023, whereby UGI has committed to fund any such EBITDA shortfalls and debt service, if any. Based on the support and the projected EBITDA, AmeriGas OLP is expected to remain in compliance with its financial debt covenants for the succeeding twelve-month period. UGI International 2023 Credit Facilities Agreement. On March 7, 2023, UGI International, LLC and its indirect wholly-owned subsidiary, UGI International Holdings B.V., entered into the UGI International 2023 Credit Facilities Agreement, a five-year unsecured senior facilities agreement, maturing March 7, 2028, with a consortium of banks. The UGI International 2023 Credit Facilities Agreement consists of (1) a €300 variable-rate term loan facility ("Facility A") and (2) a €500 multicurrency revolving credit facility, including a €100 sublimit for swingline loans ("Facility B"). We have designated borrowings under Facility A as a net investment hedge. In connection with the entering into of the UGI International 2023 Credit Facilities Agreement, UGI International, LLC paid off in full and terminated the UGI International Credit Facilities Agreement, dated as of October 18, 2018. The net proceeds from the UGI International 2023 Credit Facilities Agreement were used to refinance the UGI International Credit Facilities Agreement. Borrowings under the multicurrency revolving credit facility may be used to finance the working capital needs of UGI International, LLC and its subsidiaries and for general corporate purposes. Borrowings under Facility A bear interest at the euro interbank offered rate plus the applicable margin and borrowings under Facility B bear interest at the daily non-cumulative compounded Reference Rate Terms, as defined in the Agreement plus the applicable margin. The applicable margin for Facility A ranges from 1.70% to 3.35%, and for Facility B from 1.35% to 3.35%, and are dependent on the total net leverage ratio of UGI International, LLC and its subsidiaries on a consolidated basis. UGI International, LLC entered into an interest rate swap, effective March 31, 2023, that fixes the underlying market-based interest rate on Facility A at 3.10% through March 2026. The UGI International 2023 Credit Facilities Agreement requires UGI International, LLC to maintain a consolidated net leverage ratio of not more than 3.85 to 1.00, provided the maximum ratio permitted may be increased to 4.25 to 1.00 for two consecutive testing dates following a permitted acquisition. Energy Services Amended Term Loan Credit Agreement. On February 23, 2023, Energy Services entered into the Energy Services Amended Term Loan Credit Agreement, the first amendment to the Energy Services Term Loan Credit Agreement, dated August 13, 2019. The Energy Services Amended Term Loan Credit Agreement provides, among other items, that (i) the outstanding principal amount of the loans will be increased by $125 to $800, (ii) the maturity date of the loans shall be extended to February 22, 2030, (iii) Term SOFR (as defined in the Energy Services Amended Term Loan Credit Agreement) shall replace LIBOR as a reference rate and (iv) borrowings under the Energy Services Term Loan Credit Agreement shall bear interest at a floating rate of, at Energy Services’ option, either (x) Term SOFR plus the applicable margin plus a credit spread adjustment of 0.10% or (y) the base rate, as defined in the Agreement, plus the applicable margin. The applicable margin shall be 3.25% per annum for Term SOFR loans and 2.25% per annum for base rate loans. Borrowings under the Energy Services Amended Term Loan Credit Agreement are payable in equal quarterly installments of $2, commencing in March 2023, with the balance of the principal being due and payable in full at maturity. The Energy Services Amended Term Loan Credit Agreement contains customary covenants and default provisions and requires compliance with certain financial covenants including a minimum debt service coverage ratio as defined in the Agreement. On March 1, 2023, in connection with the Energy Services Amended Term Loan Credit Agreement, Energy Services terminated and settled its existing interest rate swap derivative instrument associated with the Energy Services Term Loan Credit Agreement at a $32 gain. In accordance with GAAP, this gain has been deferred in AOCI and will be amortized to interest expense over the remaining term of the initial interest rate swap. Energy Services entered into a new interest rate swap, effective March 31, 2023, that fixes the underlying market-based interest rate on this variable-rate term loan at 4.53% through September 2026. UGI Utilities Credit Agreement. On December 13, 2022, UGI Utilities entered into an amendment to the UGI Utilities Credit Agreement, providing for borrowings up to $425 and to replace the use of LIBOR with SOFR. Borrowings under the amended UGI Utilities Credit Agreement can be used to finance the working capital needs of UGI Utilities and for general corporate purposes. The UGI Utilities Credit Agreement is scheduled to expire June 2024. Borrowings under the amended UGI Utilities Credit Agreement bear interest, subject to our election, at a floating rate of either (i) Term SOFR plus the applicable margin plus a credit spread adjustment of 0.10% or (ii) the base rate plus the applicable margin. The applicable margin remains unchanged from the original credit agreement. Mountaineer Credit Agreement. On October 20, 2022, Mountaineer entered into the Mountaineer 2023 Credit Agreement, with a group of lenders. The Mountaineer 2023 Credit Agreement amends and restates a previous credit agreement and provides for borrowings up to $150, including a $20 sublimit for letters of credit. Mountaineer may request an increase in the amount of loan commitments to a maximum aggregate amount of $250, subject to certain terms and conditions. Borrowings under the Mountaineer 2023 Credit Agreement can be used to finance the working capital needs of Mountaineer and for general corporate purposes. The Mountaineer 2023 Credit Agreement is scheduled to expire in November 2024, with an option to extend the maturity date.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Note 9 — Commitments and Contingencies Environmental Matters UGI Utilities From the late 1800s through the mid-1900s, UGI Utilities and its former subsidiaries owned and operated a number of MGPs prior to the general availability of natural gas. Some constituents of coal tars and other residues of the manufactured gas process are today considered hazardous substances under the Superfund Law and may be present on the sites of former MGPs. Between 1882 and 1953, UGI Utilities owned the stock of subsidiary gas companies in Pennsylvania and elsewhere and also operated the businesses of some gas companies under agreement. By the early 1950s, UGI Utilities divested all of its utility operations other than certain gas and electric operations. Beginning in 2006 and 2008, UGI Utilities also owned and operated two acquired subsidiaries, with similar histories of owning, and in some cases operating, MGPs in Pennsylvania. UGI Utilities is subject to a COA with the PADEP to address the remediation of specified former MGP sites in Pennsylvania, which is scheduled to terminate at the end of 2031. In accordance with the COA, UGI Utilities is required to either obtain a certain number of points per calendar year based on defined eligible environmental investigatory and/or remedial activities at the MGPs, or make expenditures for such activities in an amount equal to an annual environmental minimum expenditure threshold. The annual minimum expenditure threshold of the COA is $5. The COA permits the transfer of the specified wells, with related costs counted towards the annual minimum expenditure. At March 31, 2023, September 30, 2022 and March 31, 2022, our aggregate estimated accrued liabilities for environmental investigation and remediation costs related to the current COA and the predecessor agreements totaled $52, $53 and $49, respectively. We do not expect the costs for investigation and remediation of hazardous substances at Pennsylvania MGP sites to be material to UGI Utilities’ results of operations because UGI Utilities receives ratemaking recovery of actual environmental investigation and remediation costs associated with the sites covered by the COA. This ratemaking recognition reconciles the accumulated difference between historical costs and rate recoveries with an estimate of future costs associated with the sites. As such, UGI Utilities has recorded an associated regulatory asset for these costs because recovery of these costs from customers is probable (see Note 7). From time to time, UGI Utilities is notified of sites outside Pennsylvania on which private parties allege MGPs were formerly owned or operated by UGI Utilities or owned or operated by a former subsidiary. Such parties generally investigate the extent of environmental contamination or perform environmental remediation. Management believes that under applicable law, UGI Utilities should not be liable in those instances in which a former subsidiary owned or operated an MGP. There could be, however, significant future costs of an uncertain amount associated with environmental damage caused by MGPs outside Pennsylvania that UGI Utilities directly operated, or that were owned or operated by a former subsidiary of UGI Utilities if a court were to conclude that (1) the subsidiary’s separate corporate form should be disregarded, or (2) UGI Utilities should be considered to have been an operator because of its conduct with respect to its subsidiary’s MGP. Neither the undiscounted nor the accrued liability for environmental investigation and cleanup costs for UGI Utilities’ MGP sites outside Pennsylvania were material for all periods presented. AmeriGas Propane AmeriGas OLP Saranac Lake. In 2008, the NYDEC notified AmeriGas OLP that the NYDEC had placed property purportedly owned by AmeriGas OLP in Saranac Lake, New York on the New York State Registry of Inactive Hazardous Waste Disposal Sites. A site characterization study performed by the NYDEC disclosed contamination related to a former MGP. AmeriGas OLP responded to the NYDEC in 2009 to dispute the contention it was a PRP as it did not operate the MGP and appeared to only own a portion of the site. In 2017, the NYDEC communicated to AmeriGas OLP that the NYDEC had previously issued three RODs related to remediation of the site totaling approximately $28 and requested additional information regarding AmeriGas OLP’s purported ownership. AmeriGas OLP renewed its challenge to designation as a PRP and identified potential defenses. The NYDEC subsequently identified a third party PRP with respect to the site. The NYDEC commenced implementation of the remediation plan in the spring of 2018. Based on our evaluation of the available information as of March 31, 2023, the Partnership has an undiscounted environmental remediation liability of $8 related to the site. Our share of the actual remediation costs could be significantly more or less than the accrued amount. In addition to the matters described above, there are other pending claims and legal actions arising in the normal course of our businesses. Although we cannot predict the final results of these pending claims and legal actions, including those described above, we believe, after consultation with counsel, that the final outcome of these matters will not have a material effect on our financial statements. Other Matters West Reading, Pennsylvania Explosion . On March 24, 2023, an explosion occurred in West Reading, Pennsylvania which resulted in seven fatalities, significant injuries to eleven others, and extensive property damage. The NTSB, OSHA and the PAPUC are investigating the West Reading incident. The NTSB investigative team includes representatives from the Company, the PAPUC, the local Fire Department and the Pipeline and Hazardous Materials Safety Administration. The Company is cooperating with the investigation. The NTSB may invite other parties to participate. While the investigation into this incident is still underway and the cause of the explosion has not been determined, the Company has received claims as a result of the explosion and is involved in lawsuits relative to the incident. The Company maintains liability insurance for personal injury, property and casualty damages and believes that third-party claims associated with the explosion, in excess of the Company’s deductible, are recoverable through the Company’s insurance. The Company cannot predict the result of these pending or future claims and legal actions at this time.

(b) Includes derivative assets and liabilities held-for-sale associated with the October 2022 sale of the U.K. energy marketing business (see Note 5). The fair values of our Level 1 exchange-traded commodity futures and option contracts and non-exchange-traded commodity futures and forward contracts are based upon actively quoted market prices for identical assets and liabilities. Substantially all of the remaining derivative instruments are designated as Level 2. The fair values of certain non-exchange-traded commodity derivatives designated as Level 2 are based upon indicative price quotations available through brokers, industry price publications or recent market transactions and related market indicators. The fair values of our Level 2 interest rate contracts and foreign currency contracts are based upon third-party quotes or indicative values based on recent market transactions. The fair values of our Level 3 natural gas commodity contracts at September 30, 2022 attributable to our UGI International operations have been determined using unobservable inputs in an illiquid market and ranged from $7 to $27 given the available inputs considered. The actual realized value at which these contracts will settle could vary significantly compared to the fair values reflected at September 30, 2022. The fair values of investments held in grantor trusts are derived from quoted market prices as substantially all of the investments in these trusts have active markets. Other Financial Instruments The carrying amounts of other financial instruments included in current assets and current liabilities (except for current maturities of long-term debt) approximate their fair values because of their short-term nature. We estimate the fair value of long-term debt by using current market rates and by discounting future cash flows using rates available for similar type debt (Level 2). The carrying amounts and estimated fair values of our long-term debt (including current maturities but excluding unamortized debt issuance costs) were as follows: March 31, 2023 September 30, 2022 March 31, 2022 Carrying amount $ 6,805 $ 6,665 $ 6,559 Estimated fair value $ 6,480 $ 6,189 $ 6,543

Derivative Instruments and Hedg

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Instruments and Hedging Activities	Note 12 — Derivative Instruments and Hedging Activities We are exposed to certain market risks related to our ongoing business operations. Management uses derivative financial and commodity instruments, among other things, to manage: (1) commodity price risk; (2) interest rate risk; and (3) foreign currency exchange rate risk. Although we use derivative financial and commodity instruments to reduce market risk associated with forecasted transactions, we do not use derivative financial and commodity instruments for speculative or trading purposes. The use of derivative instruments is controlled by our risk management and credit policies, which govern, among other things, the derivative instruments we can use, counterparty credit limits and contract authorization limits. Although our commodity derivative instruments extend over a number of years, a significant portion of our commodity derivative instruments economically hedge commodity price risk during the next twelve months. For information on the accounting for our derivative instruments, see Note 2. The following summarizes the types of derivative instruments used by the Company to manage certain market risks: Commodity Price Risk Regulated Utility Operations Natural Gas PA Gas Utility’s tariffs contain clauses that permit recovery of all prudently incurred costs of natural gas it sells to retail core-market customers, including the cost of financial instruments used to hedge purchased gas costs. As permitted and agreed to by the PAPUC pursuant to PA Gas Utility’s annual PGC filings, PA Gas Utility currently uses NYMEX natural gas futures and option contracts to reduce commodity price volatility associated with a portion of the natural gas it purchases for its retail core-market customers. See Note 7 for further information on the regulatory accounting treatment for these derivative instruments. Non-utility Operations LPG In order to manage market price risk associated with the Partnership’s fixed-price programs and to reduce the effects of short-term commodity price volatility, the Partnership uses over-the-counter derivative commodity instruments, principally price swap contracts. In addition, the Partnership and our UGI International operations also use over-the-counter price swap and option contracts to reduce commodity price volatility associated with a portion of their forecasted LPG purchases. Natural Gas In order to manage market price risk relating to fixed-price sales contracts for physical natural gas, Midstream & Marketing enters into NYMEX and over-the-counter natural gas futures and over-the-counter and ICE natural gas basis swap contracts. In addition, Midstream & Marketing uses NYMEX and over-the-counter futures and options contracts to economically hedge price volatility associated with the gross margin derived from the purchase and anticipated later near-term sale of natural gas storage inventories. Outside of the financial market, Midstream & Marketing also uses ICE and over-the-counter forward physical contracts. UGI International also uses natural gas futures and forward contracts to economically hedge market price risk associated with a substantial portion of anticipated volumes under fixed-price sales contracts with its customers. Electricity In order to manage market price risk relating to fixed-price sales contracts for electricity, Midstream & Marketing enters into electricity futures and forward contracts. Midstream & Marketing also uses NYMEX and over-the-counter electricity futures contracts to economically hedge the price of a portion of its anticipated future sales of electricity from its electric generation facilities. UGI International also uses electricity futures and forward contracts to economically hedge market price risk associated with fixed-price sales and purchase contracts for electricity. Interest Rate Risk Certain of our long-term debt agreements have interest rates that are generally indexed to short-term market interest rates. In order to fix the underlying short-term market interest rates, we may enter into pay-fixed, receive-variable interest rate swap agreements and designate such swaps as cash flow hedges. The remainder of our long-term debt is typically issued at fixed rates of interest. As this long-term debt matures, we typically refinance such debt with new debt having interest rates reflecting then-current market conditions. In order to reduce market rate risk on the underlying benchmark rate of interest associated with near- to medium-term forecasted issuances of fixed-rate debt, from time to time, we enter into IRPAs. We account for IRPAs as cash flow hedges. There were no unsettled IRPAs during any of the periods presented. At March 31, 2023, the amount of pre-tax net gains associated with interest rate hedges expected to be reclassified into earnings during the next twelve months is $39. Foreign Currency Exchange Rate Risk Forward Foreign Currency Exchange Contracts In order to reduce the volatility in net income associated with our foreign operations, principally as a result of changes in the USD exchange rate to the euro and British pound sterling, we enter into forward foreign currency exchange contracts. We layer in these foreign currency exchange contracts over multi-year periods to eventually equal approximately 90% of anticipated UGI International foreign currency earnings before income taxes. Because these contracts are not designated as hedging instruments, realized and unrealized gains and losses on these contracts are recorded in “Other non-operating income (expense), net,” on the Condensed Consolidated Statements of Income. Net Investment Hedges From time to time, we also enter into certain forward foreign currency exchange contracts to reduce the volatility of the USD value of a portion of our UGI International euro-denominated net investments, including anticipated foreign currency denominated dividends. We account for these foreign currency exchange contracts as net investment hedges and all changes in the fair value of these contracts are reported in the cumulative translation adjustment component in AOCI. We use the spot rate method to measure ineffectiveness of our net investment hedges. Concurrent with the repayment of UGI International’s 3.25% Senior Notes on December 7, 2021, we settled an associated net investment hedge having a notional value of €93. Additionally, in May 2022, we restructured certain net investment hedges associated with anticipated foreign currency denominated dividends. Cash flows from these settlements are included in cash flows from investing activities on the Condensed Consolidated Statements of Cash Flows. Our euro-denominated long-term debt has also been designated as net investment hedges, representing a portion of our UGI International euro-denominated net investment. We recognized pre-tax (losses) gains associated with these net investment hedges in the cumulative translation adjustment component in AOCI of $(9) and $21 during the three months ended March 31, 2023 and 2022, respectively, and $(73) and $34 during the six months ended March 31, 2023 and 2022, respectively. Quantitative Disclosures Related to Derivative Instruments The following table summarizes by derivative type the gross notional amounts related to open derivative contracts at March 31, 2023, September 30, 2022 and March 31, 2022, and the final settlement dates of the Company's open derivative contracts as of March 31, 2023, but excluding those derivatives that qualified for the NPNS exception: Notional Amounts Type Units Settlements Extending Through March 31, 2023 September 30, 2022 March 31, 2022 Commodity Price Risk: Regulated Utility Operations PA Gas Utility NYMEX natural gas futures and option contracts Dekatherms February 2024 12 19 11 Non-utility Operations LPG swaps Gallons September 2025 691 874 622 Natural gas futures, forward, basis swap, options and pipeline contracts (a) Dekatherms October 2027 366 363 346 Electricity forward and futures contracts Kilowatt hours December 2026 1,890 2,446 3,098 Interest Rate Risk: Interest rate swaps Euro March 2026 € 300 € 300 € 300 Interest rate swaps USD September 2026 $ 1,277 $ 1,358 $ 1,414 Foreign Currency Exchange Rate Risk: Forward foreign currency exchange contracts USD August 2025 $ 285 $ 465 $ 274 Net investment hedge forward foreign exchange contracts Euro December 2026 € 331 € 411 € 486 (a) September 30, 2022 includes amounts held-for-sale associated with the October 2022 sale of the U.K. energy marketing business (see Note 5). Derivative Instrument Credit Risk We are exposed to risk of loss in the event of nonperformance by our derivative instrument counterparties. Our derivative instrument counterparties principally comprise large energy companies and major U.S. and international financial institutions. We maintain credit policies with regard to our counterparties that we believe reduce overall credit risk. These policies include evaluating and monitoring our counterparties’ financial condition, including their credit ratings, and entering into agreements with counterparties that govern credit limits or entering into netting agreements that allow for offsetting counterparty receivable and payable balances for certain financial transactions, as deemed appropriate. We have concentrations of credit risk associated with derivative instruments and we evaluate the creditworthiness of our derivative counterparties on an ongoing basis. As of March 31, 2023, the maximum amount of loss, based upon the gross fair values of the derivative instruments, we would incur if these counterparties failed to perform according to the terms of their contracts was $422. In general, many of our over-the-counter derivative instruments and all exchange contracts call for the posting of collateral by the counterparty or by the Company in the forms of letters of credit, parental guarantees or cash. At March 31, 2023, we had received cash collateral from derivative instrument counterparties totaling $55. In addition, we may have offsetting derivative liabilities and certain accounts payable balances with certain of these counterparties, which further mitigates the previously mentioned maximum amount of losses. Certain of the Partnership’s derivative contracts have credit-risk-related contingent features that may require the posting of additional collateral in the event of a downgrade of the Partnership’s debt rating. At March 31, 2023, if the credit-risk-related contingent features were triggered, the amount of collateral required to be posted would not be material. Offsetting Derivative Assets and Liabilities Derivative assets and liabilities are presented net by counterparty on the Condensed Consolidated Balance Sheets if the right of offset exists. We offset amounts recognized for the right to reclaim cash collateral or the obligation to return cash collateral against amounts recognized for derivative instruments executed with the same counterparty. Our derivative instruments include both those that are executed on an exchange through brokers and centrally cleared and over-the-counter transactions. Exchange contracts utilize a financial intermediary, exchange or clearinghouse to enter, execute or clear the transactions. Over-the-counter contracts are bilateral contracts that are transacted directly with a third party. Certain over-the-counter and exchange contracts contain contractual rights of offset through master netting arrangements, derivative clearing agreements and contract default provisions. In addition, the contracts are subject to conditional rights of offset through counterparty nonperformance, insolvency or other conditions. In general, many of our over-the-counter transactions and all exchange contracts are subject to collateral requirements. Types of collateral generally include cash or letters of credit. Cash collateral paid by us to our over-the-counter derivative counterparties, if any, is reflected in the table below to offset derivative liabilities. Cash collateral received by us from our over-the-counter derivative counterparties, if any, is reflected in the table below to offset derivative assets. Certain other accounts receivable and accounts payable balances recognized on the Condensed Consolidated Balance Sheets with our derivative counterparties are not included in the table below but could reduce our net exposure to such counterparties because such balances are subject to master netting or similar arrangements. Fair Value of Derivative Instruments The following table presents the Company’s derivative assets and liabilities by type, as well as the effects of offsetting: March 31, September 30, March 31, Derivative assets: Derivatives designated as hedging instruments: Foreign currency contracts $ 9 $ 57 $ 18 Interest rate contracts 25 66 31 34 123 49 Derivatives subject to PGC and DS mechanisms: Commodity contracts 19 31 38 Derivatives not designated as hedging instruments: Commodity contracts (a) 355 2,202 1,931 Foreign currency contracts 14 62 17 369 2,264 1,948 Total derivative assets — gross 422 2,418 2,035 Gross amounts offset in the balance sheet (190) (295) (215) Cash collateral received (55) (398) (603) Total derivative assets — net $ 177 $ 1,725 $ 1,217 Derivative liabilities: Derivatives designated as hedging instruments: Interest rate contracts (21) — (1) Derivatives subject to PGC and DS mechanisms: Commodity contracts (36) (26) (17) Derivatives not designated as hedging instruments: Commodity contracts (a) (396) (487) (304) Foreign currency contracts (4) (2) (2) (400) (489) (306) Total derivative liabilities — gross (457) (515) (324) Gross amounts offset in the balance sheet 190 295 215 Cash collateral pledged 102 7 — Total derivative liabilities — net $ (165) $ (213) $ (109) (a) September 30, 2022 includes derivative assets and liabilities held-for-sale associated with the October 2022 sale of the U.K. energy marketing business (see Note 5).

However, these contracts qualify for NPNS exception accounting because they provide for the delivery of products or services in quantities that are expected to be used in the normal course of operating our business and the price in the contract is based on an underlying that is directly associated with the price of the product or service being purchased or sold. These contracts include, among others, binding purchase orders, contracts that provide for the purchase and delivery, or sale, of energy products, and service contracts that require the counterparty to provide commodity storage, transportation or capacity service to meet our normal sales commitments.

Accounting Policies [Abstract]
Restricted Cash	Restricted Cash.
Earnings Per Common Share	Earnings Per Common Share.
Equity Method Investments	Equity Method Investments. We account for privately held equity securities of entities without readily determinable fair values in which we do not have control, but have significant influence over operating and financial policies, under the equity method. These are included in "Other assets" on the Condensed Consolidated Balance Sheets. Equity method earnings are included in "Income from equity method investees" on the Condensed Consolidated Statements of Income. Our equity method investments primarily comprise MBL Bioenergy, Pine Run and other equity method investments in biomass and other renewable energy projects. MBL Bioenergy . The Company has an approximate 99.99% interest in MBL Bioenergy, a company jointly owned by UGI Dakota, LLC, Sevana Bioenergy and a subsidiary of California Bioenergy. The sole purpose of MBL Bioenergy is the development of RNG projects in South Dakota comprising three dairy waste anaerobic digester systems. MBL Bioenergy is a variable interest entity whereby the Company has determined that it is not the primary beneficiary since it does not direct the activities that most significantly impact the entity’s economic performance. The carrying value of our investment in MBL Bioenergy at March 31, 2023 and 2022 was $78 and $0, respectively. Pine Run. The Company has an approximately 49% interest in Pine Run, a company jointly owned by Stonehenge Energy Resources and UGI Pine Run LLC. Pine Run owns Pine Run Midstream which operates dry gas gathering pipelines and compression assets in western Pennsylvania. The carrying value of our investment in Pine Run at March 31, 2023 and 2022 was $72 and $65, respectively. Pennant . At March 31, 2022, the carrying value of our investment in Pennant was $97. During Fiscal 2022, UGI through Energy Services, completed the Pennant Acquisition in which Energy Services acquired the remaining 53% of the equity interests in Pennant. The acquisition of the remaining interests was accounted for as an acquisition of assets, and the purchase price of approximately $61 was primarily allocated to property, plant and equipment. Other Equity Method Investments . Our other equity method investments totaled $69 and $26 at March 31, 2023 and 2022, respectively, and principally comprise of a number of investments in biomass and other renewable energy projects at Midstream & Marketing and a renewable energy joint venture at UGI International. Our maximum exposure to loss related to these investments is limited to the amount invested.
Derivative Instruments	Derivative Instruments. Derivative instruments are reported on the Condensed Consolidated Balance Sheets at their fair values, unless the NPNS exception is elected. The accounting for changes in fair value depends upon the purpose of the derivative instrument, whether it is subject to regulatory ratemaking mechanisms or if it qualifies and is designated as a hedge for accounting purposes. Certain of our derivative instruments qualify and are designated as cash flow hedges. For cash flow hedges, changes in the fair values of the derivative instruments are recorded in AOCI, to the extent effective at offsetting changes in the hedged item, until earnings are affected by the hedged item. We discontinue cash flow hedge accounting if occurrence of the forecasted transaction is determined to be no longer probable. Hedge accounting is also discontinued for derivatives that cease to be highly effective. We do not designate our commodity and certain foreign currency derivative instruments as hedges under GAAP. Changes in the fair values of these derivative instruments are reflected in net income. Gains and losses on substantially all of the commodity derivative instruments used by Utilities are included in regulatory assets or liabilities because it is probable such gains or losses will be recoverable from, or refundable to, customers. From time to time, we also enter into net investment hedges. Gains and losses on net investment hedges that relate to our foreign operations are included in the cumulative translation adjustment component in AOCI until such foreign net investment is substantially sold or liquidated. Cash flows from derivative instruments, other than certain cross-currency swaps and net investment hedges, if any, are included in cash flows from operating activities on the Condensed Consolidated Statements of Cash Flows. Cash flows from the interest portion of our cross-currency hedges, if any, are included in cash flows from operating activities while cash flows from the currency portion of such hedges, if any, are included in cash flows from financing activities. Cash flows from net investment hedges, if any, are included in cash flows from investing activities on the Condensed Consolidated Statements of Cash Flows.
Use of Estimates	Use of Estimates. The preparation of financial statements in accordance with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues, expenses and costs. These estimates are based on management’s knowledge of current events, historical experience and various other assumptions that are believed to be reasonable under the circumstances. Accordingly, actual results may be different from these estimates and assumptions.
Goodwill	Goodwill. We do not amortize goodwill, but test it at least annually for impairment at the reporting unit level. A reporting unit is an operating segment, or one level below an operating segment (a component) if it constitutes a business for which discrete financial information is available and regularly reviewed by segment management. Components are aggregated into a single reporting unit if they have similar economic characteristics. Each of our reporting units with goodwill is required to perform impairment tests annually or whenever events or circumstances indicate that the value of goodwill may be impaired.
New Accounting Standard Adopted	New Accounting Standard Adopted in Fiscal 2023 Debt and Derivatives and Hedging. Effective October 1, 2022, the Company adopted ASU 2020-06, “Debt - Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging – Contracts in Entity’s Own Equity (Subtopic 815-40).” The amendments in this ASU affect entities that issue convertible instruments and/or contracts indexed to and potentially settled in an entity’s own equity. This ASU reduces the number of accounting models for convertible debt instruments and convertible preferred stock, expands disclosure requirements for convertible instruments, and simplifies the related earnings per share guidance. We adopted this ASU using the modified retrospective transition method and applied the new guidance to applicable features of our Equity Units. Periods prior to October 1, 2022 have not been restated. Upon adoption, we reclassified $6 from Common Stock to Preferred Stock associated with the previously separated equity-classified beneficial conversion feature, which was accounted for as a deemed dividend. The increase to Preferred Stock was partially offset by an increase of $1 to opening retained earnings for the previously recognized non-cash amortization of the beneficial conversion feature. The ASU 2020-06 also removes the presumption of cash settlement for contracts that may be settled in cash or shares. In accordance with the new guidance, we included the dilutive impact of the quarterly contract adjustment payment liability associated with the 2024 Purchase Contracts, which may be settled in cash or shares, in our computation of weighted average diluted common shares outstanding. The adoption of the new guidance did not, and is not expected to, have a material impact on our consolidated financial statements.
