Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Note 1 — Summary of Significant Accounting Policies Principles of Consolidation The accompanying condensed consolidated financial statements of Cleco include the accounts of Cleco and its majority-owned subsidiaries after elimination of intercompany accounts and transactions. Following the formation of Cleco Securitization I and the closing of the storm recovery securitization financing on June 22, 2022, Cleco Power became the primary beneficiary of Cleco Securitization I, and as a result, the financial statements of Cleco Securitization I are consolidated with the financial statements of Cleco Power. For additional information about Basis of Presentation The condensed consolidated financial statements of Cleco and Cleco Power have been prepared in accordance with GAAP for interim financial information and with the instructions to Form 10-Q and Regulation S-X. Accordingly, these condensed consolidated financial statements do not include all of the information and notes required by GAAP for annual financial statements. The year-end condensed consolidated balance sheet data was derived from audited financial statements and adjusted for discontinued operations. Because the interim condensed consolidated financial statements and the accompanying notes do not include all of the information and notes required by GAAP for annual financial statements, the condensed consolidated financial statements and other information included in this Quarterly Report on Form 10-Q should be read in conjunction with the consolidated financial statements and accompanying notes in the Registrants’ Combined Annual Report on Form 10-K for the fiscal year ended December 31, 2022. These condensed consolidated financial statements, in the opinion of management, reflect all normal recurring adjustments that are necessary for a fair statement of the financial position and results of operations of Cleco and Cleco Power. Amounts reported in Cleco’s and Cleco Power’s interim financial statements are not necessarily indicative of amounts expected for the annual periods due to the effects of seasonal temperature variations on energy consumption, regulatory rulings, the timing of maintenance on electric generating units, changes in mark-to-market valuations, changing commodity prices, discrete income tax items, and other factors. In preparing financial statements that conform to GAAP, management must make estimates and assumptions that affect the reported amounts of assets and liabilities, the reported amounts of revenues and expenses, and the disclosure of contingent assets and liabilities at the date of the financial statements. Actual results could differ from those Various agreements to which Cleco is subject contain covenants that restrict its use of cash. As certain provisions under these agreements are met, cash is transferred out of related escrow accounts and becomes available for its intended purposes and/or general corporate purposes. Cleco’s and Cleco Power’s restricted cash and cash equivalents consisted of the following: Cleco (THOUSANDS) AT SEPT. 30, 2023 AT DEC. 31, 2022 Current Cleco Power’s storm restoration costs - Hurricane Ida $ — $ 9,409 Cleco Securitization I’s operating expenses and storm recovery bond issuance costs and debt service 6,356 14,140 Total current 6,356 23,549 Non-current Diversified Lands’ mitigation escrow 23 23 Cleco Power’s future storm restoration costs 111,995 103,306 Cleco Power’s storm restoration costs - Hurricane Ida — 6,086 Total non-current 112,018 109,415 Total restricted cash and cash equivalents $ 118,374 $ 132,964 Cleco Power (THOUSANDS) AT SEPT. 30, 2023 AT DEC. 31, 2022 Current Storm restoration costs - Hurricane Ida $ — $ 9,409 Cleco Securitization I’s operating expenses and storm recovery bond issuance costs 6,356 14,140 Total current 6,356 23,549 Non-current Future storm restoration costs 111,995 103,306 Storm restoration costs - Hurricane Ida — 6,086 Total non-current 111,995 109,392 Total restricted cash and cash equivalents $ 118,351 $ 132,941 On September 20, 2023, the LPSC approved a settlement for the prudency review of the remaining unrecovered Hurricane Ida storm restoration costs deferred as a regulatory asset. The settlement allowed Cleco Power to withdraw the remaining unrecovered Hurricane Ida storm restoration costs, Reserves for Credit Losses Customer accounts receivable are recorded at the invoiced amount and do not bear interest. Customer accounts receivable are generally considered to become past due 20 days after the billing date. Cleco recognizes write-offs within the allowance for credit losses once all recovery methods have been exhausted. It is the policy of management to review accounts receivable and unbilled revenue monthly using a reserve matrix based on historical bad debt write-offs, as well as current and forecasted economic conditions, to establish a credit loss estimate. Management’s historical credit loss analysis included periods of economic recessions, natural disasters, and temporary changes to collection policies. Due to the critical necessity of electricity, none of these past events have significantly impacted Cleco’s credit loss rates. As a result of the market price volatility of natural gas throughout 2022, Cleco experienced significant increases to the pass-through fuel component of retail customer energy bills. Due to these increased customer costs, along with the impacts of a 40-year high inflation rate, Cleco experienced increases in credit loss reserves. These factors have not been and are not expected to be material to Cleco’s results of operations, financial condition, or cash flows. During the third quarter of 2023, Cleco's service territory experienced sustained record high temperatures resulting in an increase in usage by its customers. In anticipation of higher customer costs and high heat conditions, Cleco temporarily suspended disconnections and the utilization of collection agencies for the month of August and most of September 2023, resulting in no additional charge-offs during these months. On September 25, 2023, Cleco resumed disconnection and collection activities. Although Cleco’s service territory experienced various external impacts, Cleco’s credit losses at September 30, 2023, were still within range of its historical credit loss analysis. The tables below present the changes in the allowance for credit losses by receivable for Cleco and Cleco Power: Cleco FOR THE THREE MONTHS ENDED SEPT. 30, 2023 FOR THE NINE MONTHS ENDED SEPT. 30, 2023 (THOUSANDS) ACCOUNTS OTHER* TOTAL ACCOUNTS OTHER* TOTAL Balances, beginning of period $ 1,252 $ 1,638 $ 2,890 $ 1,147 $ 1,638 $ 2,785 Current period provision 1,106 — 1,106 3,252 — 3,252 Charge-offs (325) — (325) (3,071) — (3,071) Recovery 215 — 215 920 — 920 Balances, Sept. 30, 2023 $ 2,248 $ 1,638 $ 3,886 $ 2,248 $ 1,638 $ 3,886 * Loan held at Diversified Lands that was fully reserved at December 31, 2020.

Accounting Changes and Error Corrections [Abstract]
Recent Authoritative Guidance	Note 2 — Recent Authoritative Guidance In March 2023, FASB issued guidance that applies to leases between entities under common control. The guidance provides a practical expedient for determining whether an arrangement between entities under common control is a lease as well as the classification of the lease. In addition, the leasehold improvements amortization period is to be determined by the useful life to the common group rather than the term of the lease. The new guidance is effective for fiscal years beginning after December 15, 2023, including interim periods within those fiscal years. Cleco has arrangements between entities under common control and management is evaluating the impacts of this guidance on the results of operations, financial condition, and cash flows of the Registrants.

Discontinued Operations and Disposal Groups [Abstract]
Discontinued Operations	Note 3 — Discontinued Operations In March 2023, Cleco Holdings’ management, with the support of its Board of Managers, committed to a plan of action for the disposition of the Cleco Cajun Sale Group, with a sale probable and subject to customary regulatory and Board of Managers approvals. As a result, Cleco Holdings’ management determined that the criteria under GAAP for the Cleco Cajun Sale Group to be classified as held for sale were met and a sale will represent a strategic shift that will have a major effect on Cleco’s future operations and financial results. Therefore, the results of operations and financial position of the Cleco Cajun Sale Group are presented as discontinued operations, and the financial information for historical periods provided in this report has been recast to reflect this presentation. Certain expenses incurred by the Cleco Cajun Sale Group as a result of common services provided by Support Group are reflected in Cleco’s results of continuing operations due to the expected ongoing nature of those expenses. In addition, revenue recognized by Cleco Power from transmission services provided to the Cleco Cajun Sale Group is no longer eliminated upon consolidation of Cleco's financial statements and is reflected in Cleco’s results of continuing operations due to the expected ongoing nature of these services. In February 2019 in connection with the approval of the Cleco Cajun Transaction, Cleco made commitments to the LPSC that included the repayment of $400.0 million of Cleco Holdings’ debt by December 31, 2024. Proceeds from the divestiture of the Cleco Cajun Sale Group must be used to satisfy the LPSC commitment. At September 30, 2023, $132.3 million of that debt remains outstanding. Interest expense on that debt is included in discontinued operations. Cleco determined that the estimated fair value less the estimated cost to sell the Cleco Cajun Sale Group was less than the carrying value of the Cleco Cajun Sale Group at March 31, 2023, June 30, 2023, and September 30, 2023. These determinations resulted in an impairment charge of $154.0 million in the nine months ended September 30, 2023, of which $38.0 million was recognized in the three months ended September 30, 2023. The impairment charge recognized in the three months ended September 30, 2023, was primarily due to changes in assumptions related to the expected sale proceeds, probabilities assigned to potential sale scenarios, and the expected closing date. The impairment charge recognized in the nine months ended September 30, 2023, reduced the carrying value of the Cleco Cajun Sale Group to its estimated fair value less estimated cost to sell. The impairment charge is recognized in Loss from discontinued operations, net of income taxes on Cleco's Condensed Consolidated Statement of Income. The estimated fair value was based on a weighted average of potential sale scenarios that were determined through the income and market approaches. The fair value estimates involved a number of judgments and assumptions including the future performance of the Cleco Cajun Sale Group through the expected divestiture date, the expected sale proceeds and the timing of such proceeds, replacement interconnection value, and the weighted average cost of capital or discount rate. The fair value measurement of the Cleco Cajun Sale Group is classified as Level 3 in the fair value hierarchy. The following table presents the amounts that have been reclassified from continuing operations and included in discontinued operations within Cleco’s Condensed Consolidated Statements of Income for the three and nine months ended September 30, 2023, and 2022: FOR THE THREE MONTHS ENDED SEPT. 30, FOR THE NINE MONTHS ENDED SEPT. 30, (THOUSANDS) 2023 2022 2023 2022 Operating revenue, net Electric operations $ 153,025 $ 140,767 $ 385,249 $ 370,489 Other operations 34,231 39,573 95,413 111,897 Operating revenue, net 187,256 180,340 480,662 482,386 Operating expenses Fuel used for electric generation * 41,339 59,435 70,053 141,189 Purchased power 67,297 111,901 175,884 275,531 Other operations and maintenance 28,611 20,727 75,926 61,726 Depreciation and amortization 433 12,046 15,448 55,866 Total operating expenses 137,680 204,109 337,311 534,312 Operating income (loss) 49,576 (23,769) 143,351 (51,926) Other (expense) income, net (7) 12 125 96 Interest, net (1,835) (1,712) (5,545) (3,663) Loss on classification as held for sale (38,000) — (154,000) — Income (loss) from discontinued operations before income taxes 9,734 (25,469) (16,069) (55,493) Federal and state income tax expense (benefit) * 152,463 (3,609) (6,362) (920) Loss from discontinued operations, net of income taxes $ (142,729) $ (21,860) $ (9,707) $ (54,573) * For the six months ended June 30, 2023, and 2022, net (losses) gains associated with Cleco Cajun’s natural gas derivatives of $(82.4) million and $165.9 million, respectively, and the related income tax benefit (expense) of $22.2 million and $(44.7) million, respectively, were included in discontinued operations. As a result of the determination that potential buyers are no longer expected to acquire the natural gas derivative instruments in any of the potential sale scenarios, the net (losses) gains and related income tax benefit (expense) associated with the natural gas derivative instruments are no longer presented in discontinued operations. The following table presents the assets and liabilities of the Cleco Cajun Sale Group that have been reclassified as held for sale within Cleco’s Condensed Consolidated Balance Sheets as of September 30, 2023, and December 31, 2022: (THOUSANDS) AT SEPT. 30, 2023 AT DEC. 31, 2022 Cash, cash equivalents, and restricted cash equivalents $ 4,091 $ 4,067 Accounts receivable 58,733 57,822 Fuel inventory, at average cost 93,971 33,153 Materials and supplies, at average cost 35,860 34,195 Energy risk management assets 1,398 518 Property, plant, and equipment, net 636,523 649,067 Prepayments 24,655 23,601 Intangible assets - other 32,569 36,548 Other assets 21,563 23,619 Loss recognized on classification as held for sale (154,000) — Total assets held for sale - discontinued operations $ 755,363 $ 862,590 Accounts payable $ 46,209 $ 59,434 Deferred lease revenue 19,945 22,246 Intangible liabilities 12,695 13,956 Asset retirement obligations 45,702 63,725 Other liabilities 12,526 7,647 Total liabilities held for sale - discontinued operations $ 137,077 $ 167,008 Balances associated with natural gas derivative instruments are no longer presented as held for sale on Cleco’s Condensed Consolidated Balance Sheets as of September 30, 2023, and December 31, 2022, as a result of the determination that potential buyers are no longer expected to acquire the natural gas derivative instruments in any of the potential sale scenarios. Cleco has elected to present cash flows of discontinued operations combined with cash flows of continuing operations. The following table presents the cash flows from discontinued operations related to the Cleco Cajun Sale Group for the nine months ended September 30, 2023, and 2022: FOR THE NINE MONTHS ENDED SEPT. 30, (THOUSANDS) 2023 2022 Net cash provided by operating activities - discontinued operations $ 5,425 $ 4,849 Net cash used in investing activities - discontinued operations $ (5,401) $ (4,844)

Regulated Operations [Abstract]
Regulatory Assets and Liabilities	Note 5 — Regulatory Assets and Liabilities Cleco Power recognizes an asset for certain costs capitalized or deferred for recovery from customers and recognizes a liability for amounts expected to be returned to customers or collected for future expected costs. Cleco Power records these assets and liabilities based on regulatory approval and management’s ongoing assessment that it is probable these items will be recovered or refunded through the ratemaking process. Under the current regulatory environment, Cleco Power believes these regulatory assets will be fully recoverable; however, if in the future, as a result of regulatory changes or competition, Cleco Power may be required to write down these assets to the extent that such regulatory assets were determined not to be recoverable. In addition, potential deregulation of the industry, or possible future changes in the method of rate regulation of Cleco Power, could require discontinuance of the application of the authoritative guidance on regulated operations. The following table summarizes Cleco Power’s regulatory assets and liabilities: Cleco Power REMAINING RECOVERY PERIOD (YRS.)

Accumulated Deferred Fuel Cleco Power is allowed to recover the cost of fuel used for electric generation and power purchased for utility customers through the LPSC established FAC or related wholesale contract provisions, which enable Cleco Power to pass on to its customers substantially all such expenses. At September 30, 2023, Accumulated deferred fuel decreased $37.4 million as a result of lower fuel costs. Deferred Storm Restoration Costs and Storm Reserves At December 31, 2022, Cleco Power had $15.5 million recorded for the Hurricane Ida storm reserve and a regulatory asset of $9.4 million for non-capital expenses associated with Hurricane Ida that were under a prudency review by the LPSC. On September 20, 2023, the LPSC approved a settlement allowing Cleco Power to withdraw the remaining unrecovered Hurricane Ida storm restoration costs, plus a carrying charge through September 2023, totaling $10.3 million from the Hurricane Ida storm reserve. The settlement also approved the transfer of the remaining balance of the Hurricane Ida storm reserve to the restricted reserve for future storm restoration costs.

Fair Value Accounting Instrumen

Fair Value Accounting Instruments	9 Months Ended
	Sep. 30, 2023
Fair Value Disclosures [Abstract]
Fair Value Accounting Instruments	Note 6 — Fair Value Accounting Instruments Fair value is a market-based measurement based on assumptions market participants would use in pricing an asset or a liability. Cleco’s valuation techniques maximize the use of observable market-based inputs and minimize the use of unobservable inputs. Credit risk of Cleco and its counterparties is incorporated in the valuation of assets and liabilities through the use of credit reserves. Cleco utilizes a three-tier fair value hierarchy that prioritizes inputs that may be used to measure fair value. The fair value hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities and the lowest priority to unobservable inputs. In some cases, the inputs used to measure fair value might fall in different levels of the fair value hierarchy. All assets and liabilities are required to be classified in their entirety based on the lowest level of input that is significant to the fair value measurement in its entirety. Assessing the significance of a particular input may require judgment considering factors specific to the asset or liability and may affect the valuation of the asset or liability and its placement within the fair value hierarchy. Significant increases or decreases in any of those inputs in isolation could result in a significantly different fair value measurement. Cleco classifies fair value balances based on the fair value hierarchy defined as follows: • Level 1 — observable inputs that reflect unadjusted quoted prices in active markets for identical assets or liabilities that Cleco can observe as of the measurement date. • Level 2 — observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities in active markets, quoted market prices in markets that are not active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. • Level 3 — unobservable inputs for assets or liabilities whose fair value is estimated based on internally developed models or methodologies using inputs that are generally less readily observable and supported by little, if any, market activity at the measurement date. Unobservable inputs are developed based on the best available information and subject to cost-benefit constraints. Cleco applies the provisions of the fair value measurement standard to its non-recurring, non-financial measurements including business combinations as well as impairment related to goodwill and other long-lived assets. For information on the impairment related to discontinued operations, see Note 3 — “Discontinued Operations.” Fair Value Measurements on a Recurring Basis The amounts reflected in Cleco’s and Cleco Power’s Condensed Consolidated Balance Sheets at September 30, 2023, and December 31, 2022, for cash equivalents, restricted cash equivalents, accounts receivable, other accounts receivable, short-term debt, and accounts payable approximate fair value because of their short-term nature.

During the nine months ended September 30, 2023, and the year ended December 31, 2022, Cleco did not experience any transfers into or out of Level 3 of the fair value hierarchy. Short-term Investments At September 30, 2023, Cleco and Cleco Power had short-term investments in money market funds and treasury bills that have a maturity of three months or less when purchased. At December 31, 2022, Cleco and Cleco Power had short-term investments in money market funds that had a maturity of three months or less when purchased. The following tables present the short-term investments as recorded on Cleco’s and Cleco Power’s Condensed Consolidated Balance Sheets at September 30, 2023, and December 31, 2022: Cleco (THOUSANDS) AT SEPT. 30, 2023 AT DEC. 31, 2022 Cash and cash equivalents $ 172,601 $ 46,279 Current restricted cash and cash equivalents $ 6,356 $ 23,548 Non-current restricted cash and cash equivalents $ 112,017 $ 109,414 Cleco Power (THOUSANDS) AT SEPT. 30, 2023 AT DEC. 31, 2022 Cash and cash equivalents $ 99,034 $ 6,813 Current restricted cash and cash equivalents $ 6,356 $ 23,548 Non-current restricted cash and cash equivalents $ 111,994 $ 109,391 FTRs FTRs are financial instruments used to provide a financial hedge to manage the risk of transmission congestion charges between MISO nodes in MISO’s Day-Ahead Energy Market. Cleco is awarded and/or purchases FTRs in auctions facilitated by MISO. FTRs are derivatives not designated as hedging instruments for accounting purposes. FTRs are valued using MISO’s monthly auction prices as a price index reference (Level 3). Unrealized gains or losses are deferred as a component of Accumulated deferred fuel on the balance sheet in accordance with regulatory policy, and at settlement, realized gains or losses are included in Cleco Power’s FAC and reflected on customers’ bills as a component of the fuel charge. The following table summarizes the net changes in the net fair value of FTR assets and liabilities classified as Level 3 in the fair value hierarchy for Cleco and Cleco Power: FOR THE THREE MONTHS ENDED SEPT. 30, FOR THE NINE MONTHS ENDED SEPT. 30, (THOUSANDS) 2023 2022 2023 2022 Balances, beginning of period $ 6,459 $ 10,138 $ 2,276 $ 4,918 Unrealized (losses) gains * 114 (1,363) (186) 189 Purchases 12 168 8,035 7,037 Settlements (2,442) (4,205) (5,982) (7,406) Balances, end of period $ 4,143 $ 4,738 $ 4,143 $ 4,738 * Unrealized gains (losses) are reported through Accumulated deferred fuel on Cleco’s and Cleco Power’s Condensed Consolidated Balance Sheets. The following table quantifies the significant unobservable inputs used in developing the fair value of Level 3 positions for Cleco and Cleco Power as of September 30, 2023, and December 31, 2022: FAIR VALUE VALUATION TECHNIQUE SIGNIFICANT UNOBSERVABLE INPUTS FORWARD PRICE RANGE (THOUSANDS, EXCEPT FORWARD PRICE RANGE) ASSETS LIABILITIES LOW HIGH FTRs at Sept. 30, 2023 $ 4,814 $ 671 RTO auction pricing FTR price - per MWh $ (5.11) $ 7.02 FTRs at Dec. 31, 2022 $ 2,570 $ 294 RTO auction pricing FTR price - per MWh $ (5.11) $ 13.65 Natural Gas Derivatives Cleco may enter into physical and financial fixed price or options contracts that financially settle or are physically delivered at a future date. Management has not elected to apply hedge accounting to these contracts as allowed under applicable accounting standards. Cleco Power’s natural gas derivative contracts are marked-to-market with the resulting unrealized gain or loss recorded as a component of Accumulated deferred fuel on the balance sheet. At settlement, realized gains or losses are included in Cleco Power’s FAC and reflected on customer’s bills as a component of the fuel charge. Cleco Cajun’s unrealized gains or losses as well as realized gains or losses at settlement are recorded on the income statements as a component of fuel expense. Fair Value Measurements on a Nonrecurring Basis The following tables summarize the carrying value and estimated market value of Cleco’s and Cleco Power’s financial instruments not measured at fair value on Cleco’s and Cleco Power’s Condensed Consolidated Balance Sheets: Cleco AT SEPT. 30, 2023 AT DEC. 31, 2022 (THOUSANDS) CARRYING VALUE * FAIR VALUE CARRYING VALUE * FAIR VALUE Long-term debt $ 3,467,666 $ 3,064,760 $ 3,482,556 $ 3,180,208 * The carrying value of long-term debt does not include deferred issuance costs of $14.4 million at September 30, 2023, and $16.2 million at December 31, 2022. Cleco Power AT SEPT. 30, 2023 AT DEC. 31, 2022 (THOUSANDS) CARRYING VALUE * FAIR VALUE CARRYING VALUE * FAIR VALUE Long-term debt $ 1,886,170 $ 1,750,841 $ 1,895,508 $ 1,825,192 * The carrying value of long-term debt does not include deferred issuance costs of $11.2 million at September 30, 2023, and $12.3 million at December 31, 2022. In order to fund capital requirements, Cleco may issue fixed and variable rate long-term debt with various tenors. The fair value of this class fluctuates as the market interest rates for fixed and variable rate debt with similar tenors and credit ratings change. The fair value of the debt could also change from period to period due to changes in the credit rating of the Cleco entity by which the debt was issued. The fair value of long-term debt is classified as Level 2 in the fair value hierarchy. Concentrations of Credit Risk At September 30, 2023, and December 31, 2022, Cleco and Cleco Power were exposed to concentrations of credit risk through their short-term investments classified as cash equivalents and restricted cash equivalents. If the short-term investments failed to perform under the terms of the investments, Cleco and Cleco Power would be exposed to a loss of the invested amounts. Collateral on these types of investments is not required. In order to capture interest income and minimize risk, cash is invested primarily in short-term securities issued by the U.S. government to maintain liquidity and achieve the goal of a net asset value of a dollar. When Cleco enters into commodity derivative or physical commodity transactions directly with market participants, Cleco may be exposed to counterparty credit risk. Cleco is exposed to counterparty credit risk when a counterparty fails to meet their financial obligations causing Cleco to potentially incur replacement cost losses. Cleco enters into long-form contract and master agreements with counterparties that govern the risk of counterparty credit default and allow for collateralization above prenegotiated thresholds to help mitigate potential losses. Alternatively, Cleco may be required to provide credit support with respect to bilateral transactions and contracts that Cleco has entered into or may enter into in the future. The amount of credit support required may change based on margining formulas, changes in credit agency ratings, or liquidity ratios.

Debt Disclosure [Abstract]
Debt	Note 8 — Debt On February 17, 2023, Cleco Holdings and Cleco Power amended their respective revolving credit facilities and bank term loans to transition the benchmark interest rate from LIBOR to SOFR. On May 1, 2023, Cleco Holdings amended certain terms of the supplemental indenture governing its $165.0 million senior notes due in 2023. As a result, the interest rate of the senior notes changed to a floating interest rate equal to SOFR plus 1.725% and the maturity date was extended from May 1, 2023, to May 1, 2025. At September 30, 2023, and December 31, 2022, Cleco’s long-term debt and finance leases outstanding due within one year was $372.2 million and $340.9 million, respectively. The increase of $31.4 million is primarily due to the reclassification of $125.0 million of Cleco Power’s bank term loan due in May 2024, $66.7 million of Cleco Holdings’ bank term loan due in May 2024, and an additional $4.9 million of scheduled principal payments on Cleco Securitization I’s storm recovery

Retirement Benefits [Abstract]
Pension Plan and Employee Benefits	Note 9 — Pension Plan and Employee Benefits Pension Plan and Other Benefits Plan Employees hired before August 1, 2007, are covered by a non-contributory, defined benefit pension plan. Based on the funding assumptions at December 31, 2022, management estimates that pension contributions totaling $74.5 million will be required through 2027. Cleco expects to make a $25.7 million minimum required contribution to the pension plan in 2024. Cleco is not required to make any contributions to the pension plan in 2023. Cleco Power is the plan sponsor and Support Group is the plan administrator. Benefits under the plan reflect an employee’s years of service, age at retirement, and accrued benefit at retirement. Cleco’s retirees may be eligible to receive Other Benefits. Dependents of Cleco’s retirees may also be eligible to receive Other Benefits with the exception of life insurance benefits. The non-service components of net periodic pension and Other Benefits cost are included in Other income (expense), net within Cleco’s and Cleco Power’s Condensed Consolidated Statements of Income. The components of net periodic pension and Other Benefits cost for the three and nine months ended September 30, 2023, and 2022 were as follows: PENSION BENEFITS OTHER BENEFITS FOR THE THREE MONTHS ENDED SEPT. 30, FOR THE THREE MONTHS ENDED SEPT. 30, (THOUSANDS) 2023 2022 2023 2022 Components of periodic benefit costs Service cost $ 1,173 $ 2,043 $ 365 $ 546 Interest cost 6,606 4,960 566 368 Expected return on plan assets (7,386) (6,177) — — Amortizations Net loss (gain) — 3,083 (13) 298 Net periodic benefit cost $ 393 $ 3,909 $ 918 $ 1,212 PENSION BENEFITS OTHER BENEFITS FOR THE NINE MONTHS ENDED SEPT. 30, FOR THE NINE MONTHS ENDED SEPT. 30, (THOUSANDS) 2023 2022 2023 2022 Components of periodic benefit costs Service cost $ 3,520 $ 6,130 $ 1,094 $ 1,639 Interest cost 19,817 14,881 1,698 1,103 Expected return on plan assets (22,158) (18,531) — — Amortizations Net loss (gain) — 9,252 (39) 894 Net periodic benefit cost $ 1,179 $ 11,732 $ 2,753 $ 3,636 Because Cleco Power is the pension plan sponsor and the related trust holds the assets, the net unfunded status of the pension plan is reflected at Cleco Power. The liability of Cleco’s other subsidiaries is transferred, with a like amount of assets, to Cleco Power monthly. The expense of the pension plan related to Cleco’s other subsidiaries for the three and nine months ended September 30, 2023, was $0.4 million and $1.2 million, respectively. The expense of the pension plan related to Cleco’s other subsidiaries for the three and nine months ended September 30, 2022, was $0.7 million and $2.1 million, respectively. Cleco Holdings is the plan sponsor for the other benefit plans. There are no assets set aside in a trust, and the liabilities are reported on the individual subsidiaries’ financial statements. The expense related to other benefits reflected in Cleco Power’s Condensed Consolidated Statements of Income for the three and nine months ended September 30, 2023, was $0.9 million and $2.6 million, respectively. The expense related to other benefits reflected in Cleco Power’s Condensed Consolidated Statements of Income for the three and nine months ended September 30, 2022, was $1.1 million and $3.3 million, respectively. The current and non-current portions of the Other Benefits liability for Cleco and Cleco Power at September 30, 2023, and December 31, 2022, were as follows: Cleco (THOUSANDS) AT SEPT. 30, 2023 AT DEC. 31, 2022 Current $ 5,017 $ 5,017 Non-current $ 37,236 $ 38,366 Cleco Power (THOUSANDS) AT SEPT. 30, 2023 AT DEC. 31, 2022 Current $ 4,310 $ 4,310 Non-current $ 29,110 $ 30,082 SERP Certain Cleco officers are covered by SERP. Cleco does not fund the SERP liability, but instead pays for current benefits out of cash available of the respective company of the employed officer. Because the SERP is a non-qualified plan, Cleco has purchased life insurance policies on certain SERP participants as a mechanism to provide a source of funding. These policies are held in a rabbi trust formed by Cleco Power. The rabbi trust is the named beneficiary of the life insurance policies and, therefore, receives the proceeds upon the death of the insured participants. The life insurance policies may be used to reimburse Cleco for benefits paid from general funds, pay the SERP participants’ death benefits, or pay future SERP payments. Market conditions could have a significant impact on the cash surrender value of these life insurance policies. Because SERP is a non-qualified plan, the assets of the trust could be used to satisfy general creditors of Cleco Power in the event of insolvency. Cleco Power is the plan sponsor and Support Group is the plan administrator. The non-service components of net periodic benefit cost related to SERP are included in Other income (expense), net within Cleco’s and Cleco Power’s Condensed Consolidated Statements of Income. The components of the net periodic benefit cost related to SERP for the three and nine months ended September 30, 2023, and 2022 were as follows: FOR THE THREE MONTHS ENDED SEPT. 30, FOR THE NINE MONTHS ENDED SEPT. 30, (THOUSANDS) 2023 2022 2023 2022 Components of periodic benefit costs Service cost $ 35 $ 57 $ 106 $ 170 Interest cost 901 670 2,703 2,009 Amortizations Prior period service credit (54) (54) (161) (161) Net (gain) loss (16) 262 (47) 787 Net periodic benefit cost $ 866 $ 935 $ 2,601 $ 2,805 The expense related to SERP reflected on Cleco Power’s Condensed Consolidated Statements of Income for the three and nine months ended September 30, 2023, was $0.1 million and $0.4 million, respectively. The expense related to SERP reflected on Cleco Power’s Condensed Consolidated Statements of Income for the three and nine months ended September 30, 2022, was $0.1 million and $0.4 million, respectively. Liabilities relating to SERP are reported on the individual subsidiaries’ financial statements. The current and non-current portions of the SERP liability for Cleco and Cleco Power at September 30, 2023, and December 31, 2022, were as follows: Cleco (THOUSANDS) AT SEPT. 30, 2023 AT DEC. 31, 2022 Current $ 4,713 $ 4,713 Non-current $ 63,270 $ 63,714 Cleco Power (THOUSANDS) AT SEPT. 30, 2023 AT DEC. 31, 2022 Current $ 672 $ 672 Non-current $ 8,817 $ 9,087 401(k) Plan Cleco’s 401(k) Plan is intended to provide active, eligible employees with voluntary, long-term savings and investment opportunities. The 401(k) Plan is a defined contribution plan and is subject to the applicable provisions of the Employee Retirement Income Security Act of 1974. In accordance with the 401(k) Plan, employer contributions are made in the form of cash. Cash contributions are invested in proportion to the participant’s voluntary contribution investment choices. Participation in the Plan is voluntary, and active Cleco employees are eligible to participate. Cleco’s 401(k) Plan expense for the three and nine months ended September 30, 2023, and 2022 was as follows: FOR THE THREE MONTHS ENDED SEPT. 30, FOR THE NINE MONTHS (THOUSANDS) 2023 2022 2023 2022 401(k) Plan expense $ 1,741 $ 1,838 $ 5,821 $ 5,540 Cleco Power is the plan sponsor for the 401(k) Plan.

Uncertain Tax Positions Cleco classifies all interest related to uncertain tax positions as a component of interest payable and interest expense. For the three and nine months ended September 30, 2023, and 2022, Cleco and Cleco Power had no interest expense related to uncertain tax positions. At September 30, 2023, and December 31, 2022, Cleco and Cleco Power had no liability for uncertain tax positions or interest payable related to uncertain tax positions. Income Tax Audits Cleco participates in the IRS’s Compliance Assurance Process in which tax positions are examined and agreed upon prior to filing the federal tax return. While the statute of limitations remains open for tax years 2020, 2021, and 2022, the IRS has placed Cleco in the Bridge phase of the Compliance Assurance Process for the 2020 and 2021 tax years. In this phase, the IRS will not accept any disclosures, conduct any reviews, or provide any assurances. These tax returns were filed consistent with the IRS’s review. The IRS has accepted Cleco’s application for the Compliance Assurance Process for the 2022 tax year and the Compliance Assurance Maintenance phase for the 2023 tax year. In this maintenance phase, the IRS typically will, at its discretion, reduce the level of its review of the tax year relative to the regular Compliance Assurance Process phase. The state income tax years 2020, 2021, and 2022 remain subject to examination by the Louisiana Department of Revenue. Cleco classifies income tax penalties as a component of other expense. For the three and nine months ended September 30, 2023, and 2022, no penalties were recognized.

Segment Reporting [Abstract]
Segment Disclosures	Note 11 — Segment Disclosures Segment disclosures are based on Cleco’s method of internal reporting, which disaggregates business units by first-tier subsidiary. The financial information for historical periods provided in this report has been recast to reflect the presentation of the Cleco Cajun Sale Group as discontinued operations within the Other column. Cleco’s segment structure and its allocation of corporate expenses were updated to reflect how management measures performance and allocates resources. Cleco has recast data from prior periods to reflect this change to conform to the current year presentation. For more information, see Note 3 — “Discontinued Operations.” Segment managers report periodically to Cleco’s CEO, who is Cleco’s chief operating decision maker, with discrete financial information and, at least quarterly, present discrete financial information to Cleco Holdings’ and, in the case of Cleco Power, Cleco Power’s Boards of Managers. The reportable segment prepares budgets that are presented to and approved by Cleco Holdings’ and, in the case of Cleco Power, Cleco Power’s Boards of Managers. The column shown as Other in the following tables includes the holding company, a shared services subsidiary, an investment subsidiary, natural gas derivatives at Cleco Cajun, and discontinued operations. The financial results in the following tables are presented on an accrual basis. EBITDA is a key non-GAAP financial measure used by the CEO to assess the operating performance of Cleco’s segment. Management evaluates the performance of Cleco’s segment and allocates resources to it based on segment profit and the requirements to implement strategic initiatives and projects to meet current business objectives. EBITDA is defined as net income adjusted for interest, income taxes, depreciation, and amortization. Depreciation and amortization in the following tables includes amortization of intangible assets recorded for the fair value adjustment of wholesale power supply agreements as a result of the 2016 Merger. Material intercompany transactions occur on a regular basis. These intercompany transactions relate primarily to joint and common administrative support services.

Regulated Operations [Abstract]
Regulation and Rates	Note 12 — Regulation and Rates FRP On June 16, 2021, the LPSC approved Cleco Power’s current FRP. Effective July 1, 2021, under the terms of the FRP, Cleco Power is allowed to earn a target ROE of 9.5%, while providing the opportunity to earn up to 10.0%. Additionally, 60.0% of retail earnings between 10.0% and 10.5%, and all retail earnings over 10.5%, are required to be refunded to customers. The amount of credits due to customers, if any, is determined by Cleco Power and the LPSC annually. On June 30, 2023, Cleco Power filed an application with the LPSC for a new FRP, with anticipated new rates being effective July 1, 2024. Cleco Power has responded to its first set of LPSC data requests. In September 2023, the LPSC approved Cleco Power’s monitoring report for the 12 months ended June 30, 2022, indicating no material refund was due. On October 31, 2023, Cleco Power filed its monitoring report for the 12 months ended June 30, 2023, indicating no refund was due. TCJA On June 16, 2021, the LPSC approved Cleco Power’s current retail rate plan which includes the settlement of the TCJA protected and unprotected excess ADIT. Effective July 1, 2021, all retail customers continued receiving bill credits resulting from the TCJA. The target retail portion of the unprotected excess ADIT is approximately $2.5 million monthly and will be credited over a period of three years concluding on June 30, 2024. The retail portion of the protected excess ADIT will be credited until the full amount of the protected excess ADIT has been returned to Cleco Power’s customers through bill credits. At September 30, 2023, Cleco Power had $222.3 million accrued for the excess ADIT, of which $31.2 million is reflected in current regulatory liabilities. Teche Unit 3 In July 2022, Cleco Power filed an Attachment Y with MISO requesting retirement of Teche Unit 3, barring any violations of specific applicable reliability standards. On January 31, 2023, Cleco Power filed a notice with the LPSC to retire Teche Unit 3 in May 2023. However, in April 2023, Cleco Power filed notices with MISO and the LPSC to delay the retirement of Teche Unit 3. Management continues to monitor regulatory capacity requirements and customer needs to determine the appropriate timing of the retirement of Teche Unit 3.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Variable Interest Entities	Note 13 — Variable Interest Entities Cleco Securitization I Cleco Securitization I is a special-purpose, wholly owned subsidiary of Cleco Power that was formed for the purpose of issuing storm recovery bonds to finance the securitization of Storm Recovery Property at Cleco Power. On June 22, 2022, the securitized financing was complete. Cleco Securitization I’s assets cannot be used to settle Cleco Power’s obligations and the holders of the storm recovery bonds have no recourse against Cleco Power. Because Cleco Securitization I’s equity at risk is less than 1% of its total assets, it is considered to be a variable interest entity. Through its equity ownership interest and role as servicer, Cleco Power has the power to direct the most significant financial and operating activities of Cleco Securitization I, including billing, collections, and remittance of retail customer cash receipts to enable Cleco Securitization I to pay the principal and interest payments on the storm recovery bonds. Cleco Power also has the obligation to absorb losses up to its equity investment and rights to receive returns from Cleco Securitization I. Therefore, management has determined that Cleco Power is the primary beneficiary of Cleco Securitization I, and as a result, Cleco Securitization I is included in the consolidated financial statements of Cleco Power. No gain or loss was recognized upon initial consolidation. The following table summarizes the impact of Cleco Securitization I on Cleco’s and Cleco Power’s Condensed Consolidated Balance Sheets: (THOUSANDS) AT SEPT. 30, 2023 AT DEC. 31, 2022 Restricted cash - current $ 6,356 $ 14,139 Accounts receivable - affiliate 4,262 3,348 Intangible asset - securitization 402,444 413,123 Total assets $ 413,062 $ 430,610 Long-term debt due within one year $ 14,499 $ 9,574 Accounts payable - affiliate 95 165 Interest accrued 1,548 9,953 Long-term debt, net 394,787 408,741 Total liabilities 410,929 428,433 Member’s equity 2,133 2,177 Total liabilities and member’s equity $ 413,062 $ 430,610 The following table summarizes the impact of Cleco Securitization I on Cleco’s and Cleco Power’s Condensed Consolidated Statements of Income: FOR THE THREE MONTHS ENDED SEPT. 30, FOR THE NINE MONTHS ENDED SEPT. 30, (THOUSANDS) 2023 2022 2023 2022 Operating revenue $ 9,946 $ 5,025 $ 25,329 $ 5,025 Operating expenses (5,264) (90) (11,017) (90) Interest income 188 10 430 10 Interest charges, net (4,845) (4,861) (14,668) (5,342) Income (loss) before taxes $ 25 $ 84 $ 74 $ (397) Oxbow Cleco and Cleco Power apply the equity method of accounting to report the investment in Oxbow in the consolidated financial statements. Under the equity method, the assets and liabilities of this entity are reported as Equity investment in investee on Cleco’s and Cleco Power’s Condensed Consolidated Balance Sheets. The revenue and expenses (excluding income taxes) of this entity are netted and reported as equity income or loss from investees on Cleco’s and Cleco Power’s Condensed Consolidated Statements of Income. Oxbow is owned 50% by Cleco Power and 50% by SWEPCO. Cleco Power is not the primary beneficiary because it shares the power to control Oxbow’s significant activities with SWEPCO. Cleco Power’s current assessment of its maximum exposure to loss related to Oxbow at September 30, 2023, consisted of its equity investment of approximately $2.0 million .

The lignite reserves were intended to be used to provide fuel to the Dolet Hills Power Station. Under the Amended Lignite Mining Agreement, DHLC billed Cleco Power its proportionate share of incurred lignite extraction and associated mining-related costs. Oxbow billed Cleco Power its proportionate share of incurred costs related to mineral rights and land leases. On October 6, 2020, Cleco Power and SWEPCO made a joint filing with the LPSC seeking authorization to close the Oxbow mine. At December 31, 2021, the Dolet Hills Power Station was retired, and all of Cleco Power’s proportionate share of lignite-related costs had been billed by DHLC and Oxbow. For more information on DHLC and the Oxbow mine, see Note 14 — “Litigation, Other Commitments and Contingencies, and Disclosures about Guarantees — Off-Balance Sheet Commitments and Guarantees.” Oxbow has no third-party agreements, guarantees, or other third-party commitments that contain obligations affecting Cleco Power’s investment in Oxbow.

Commitments and Contingencies Disclosure [Abstract]
Litigation, Other Commitments and Contingencies, and Disclosures about Guarantees	Note 14 — Litigation, Other Commitments and Contingencies, and Disclosures about Guarantees Litigation 2016 Merger In connection with the 2016 Merger, four actions were filed in the Ninth Judicial District Court for Rapides Parish, Louisiana and three actions were filed in the Civil District Court for Orleans Parish, Louisiana. The petitions in each action generally alleged, among other things, that the members of Cleco Corporation’s Board of Directors breached their fiduciary duties by, among other things, conducting an allegedly inadequate sale process, agreeing to the 2016 Merger at a price that allegedly undervalued Cleco, and failing to disclose material information about the 2016 Merger. The petitions also alleged that Como 1, Cleco Corporation, Merger Sub, and, in some cases, certain of the investors in Como 1 either aided and abetted or entered into a civil conspiracy to advance those supposed breaches of duty. The petitions sought various remedies, including monetary damages, which includes attorneys’ fees and expenses. The four actions filed in the Ninth Judicial District Court for Rapides Parish are captioned as follows: • Braunstein v. Cleco Corporation , No. 251,383B (filed October 27, 2014), • Moore v. Macquarie Infrastructure and Real Assets , No. 251,417C (filed October 30, 2014), • Trahan v. Williamson , No. 251,456C (filed November 5, 2014), and • L’Herisson v. Macquarie Infrastructure and Real Assets , No. 251,515F (filed November 14, 2014). In November 2014, the plaintiff in the Braunstein action moved for a dismissal of the action without prejudice, and that motion was granted in November 2014. In December 2014, the court consolidated the remaining three actions and appointed interim co-lead counsel, and dismissed the investors in Cleco Partners as defendants, per agreement of the parties. Also, in December 2014, the plaintiffs in the consolidated action filed a Consolidated Amended Verified Derivative and Class Action Petition for Damages and Preliminary and Permanent Injunction. The three actions filed in the Civil District Court for Orleans Parish were captioned as follows: • Butler v. Cleco Corporation , No. 2014-10776 (filed November 7, 2014), • Creative Life Services, Inc. v. Cleco Corporation , No. 2014-11098 (filed November 19, 2014), and • Cashen v. Cleco Corporation , No. 2014-11236 (filed November 21, 2014). In December 2014, the directors and Cleco filed declinatory exceptions in each action on the basis that each action was improperly brought in Orleans Parish and should either be transferred to the Ninth Judicial District Court for Rapides Parish or dismissed. Also, in December 2014, the plaintiffs in each action jointly filed a motion to consolidate the three actions pending in Orleans Parish and to appoint interim co-lead plaintiffs and co-lead counsel. In January 2015, the Court in the Creative Life Services case sustained the defendants’ declinatory exceptions and dismissed the case so that it could be transferred to the Ninth Judicial District Court for Rapides Parish. In February 2015, the plaintiffs in Butler and Cashen also consented to the dismissal of their cases from Orleans Parish so they could be transferred to the Ninth Judicial District Court for Rapides Parish. By operation of the December 2014 order of the Ninth Judicial District Court for Rapides Parish, the Butler , Cashen , and Creative Life Services actions were consolidated into the actions pending in Rapides Parish. In February 2015, the Ninth Judicial District Court for Rapides Parish held a hearing on a motion for preliminary injunction filed by plaintiffs in the consolidated action seeking to enjoin the shareholder vote for approval of the Merger Agreement. The District Court heard and denied the plaintiffs’ motion. In June 2015, the plaintiffs filed their Second Consolidated Amended Verified Derivative and Class Action Petition. Cleco filed exceptions seeking dismissal of the second amended petition in July 2015. The LPSC voted to approve the 2016 Merger before the court could consider the plaintiffs’ peremptory exceptions. In March 2016 and May 2016, the plaintiffs filed their Third Consolidated Amended Verified Derivative Petition for Damages and Preliminary and Permanent Injunction and their Fourth Verified Consolidated Amended Class Action Petition, respectively. The fourth amended petition, which remains the operative petition and was filed after the 2016 Merger closed, eliminated the request for preliminary and permanent injunction and also named an additional executive officer as a defendant. The defendants filed exceptions seeking dismissal of the fourth amended Petition. In September 2016, the District Court granted the exceptions of no cause of action and no right of action and dismissed all claims asserted by the former shareholders. The plaintiffs appealed the District Court’s ruling to the Louisiana Third Circuit Court of Appeal. In December 2017, the Third Circuit Court of Appeal issued an order reversing and remanding the case to the District Court for further proceedings. In January 2018, Cleco filed a writ with the Louisiana Supreme Court seeking review of the Third Circuit Court of Appeal’s decision. The writ was denied in March 2018 and the parties are engaged in discovery in the District Court. In November 2018, Cleco filed renewed exceptions of no cause of action and res judicata, seeking to dismiss all claims. On December 21, 2018, the court dismissed Cleco Partners and Cleco Holdings as defendants per the agreement of the parties, leaving as the only remaining defendants certain former executive officers and independent directors. The District Court denied the defendants’ exceptions on January 14, 2019. A hearing on the plaintiffs’ motion for certification of a class was scheduled for August 26, 2019; however, prior to the hearing, the parties reached an agreement to certify a limited class. On September 7, 2019, the District Court certified a class limited to shareholders who voted against, abstained from voting, or did not vote on the 2016 Merger. On October 18, 2021, the District Court issued an order consistent with a joint motion by the parties to dismiss all claims against the former independent directors leaving two former executives as the only remaining defendants. The two former executives filed motions for summary judgment in June 2023, which the District Court denied in September 2023. In October 2023, the two former executives and plaintiffs, after mediation, entered into a memorandum of understanding for a class action settlement under which all disputes and claims asserted against the two former executives would be dismissed. The District Court’s final approval of the settlement is required before the settlement becomes effective. Gulf Coast Spinning In September 2015, a potential customer sued Cleco for failure to fully perform an alleged verbal agreement to lend or otherwise fund its startup costs to the extent of $6.5 million. Gulf Coast Spinning Company, LLC (Gulf Coast), the primary plaintiff, alleges that Cleco promised to assist it in raising approximately $60.0 million, which Gulf Coast needed to construct a cotton spinning facility near Bunkie, Louisiana (the Bunkie project). According to the petition filed by Gulf Coast in the 12 th Judicial District Court for Avoyelles Parish, Louisiana, Cleco made such promises of funding assistance in order to cultivate a new industrial electric customer which would increase its revenues under a power supply agreement that it executed with Gulf Coast. Gulf Coast seeks unspecified damages arising from its inability to raise sufficient funds to complete the project, including lost profits. Cleco filed an Exception of No Cause of Action arguing that the case should be dismissed. The 12 th Judicial District Court denied Cleco’s exception in December 2015, after considering briefs and arguments. In January 2016, Cleco appealed the 12 th Judicial District Court’s denial of its exception by filing with the Third Circuit Court of Appeal. In June 2016, the Third Circuit Court of Appeal denied the request to have the case dismissed. In July 2016, Cleco filed a writ to the Louisiana Supreme Court seeking a review of the 12 th Judicial District Court’s denial of Cleco’s exception. In November 2016, the Louisiana Supreme Court denied Cleco’s writ application. In February 2016, the parties agreed to a stay of all proceedings pending discussions concerning settlement. In May 2016, the 12 th Judicial District Court lifted the stay at the request of Gulf Coast. The parties are currently participating in discovery. Diversified Lands loaned $2.0 million to Gulf Coast for the Bunkie project. The loan was secured by a mortgage on the Bunkie project site. Diversified Lands foreclosed on the Bunkie property in February 2020 and has also asserted claims personally against the former owner of Gulf Coast. These claims are based on contracts and credit documents executed by Gulf Coast, the obligations and performance of which were personally guaranteed by the former owner of Gulf Coast. Diversified Lands is seeking recovery of the indebtedness still owed by Gulf Coast to Diversified Lands following the February 2020 foreclosure, which action has been consolidated with the litigation filed by Gulf Coast in the 12 th Judicial District Court for Avoyelles Parish, Louisiana. Discovery is ongoing and the trial date has been set for October 2024. Cleco believes all allegations made by Gulf Coast are contradicted by the written documents executed by Gulf Coast, are otherwise without merit, and that it has substantial meritorious defenses to the claims alleged by Gulf Coast. Dispute with Saulsbury Industries In October 2018, Cleco Power sued Saulsbury Industries, Inc., the former general contractor for the St. Mary Clean Energy Center project, seeking damages for Saulsbury Industries, Inc.’s failure to complete the St. Mary Clean Energy Center project on time and for costs incurred by Cleco Power in hiring a replacement general contractor. The action was filed in the Ninth Judicial District Court for Rapides Parish. Saulsbury Industries, Inc. removed the case to the U.S. District Court for the Western District of Louisiana, on March 1, 2019. On September 14, 2020, Cabot Corporation was allowed to join the case pending in the Ninth Judicial District Court for Rapides Parish. In January 2019, Cleco Power was served with a summons in Saulsbury Industries, Inc. v. Cabot Corporation and Cleco Power LLC , in the U.S. District Court for the Western District of Louisiana. Saulsbury Industries, Inc. alleged that Cleco Power and Cabot Corporation caused delays in the St. Mary Clean Energy Center project, resulting in alleged impacts to Saulsbury Industries, Inc.’s direct and indirect costs. On June 5, 2019, Cleco Power and Cabot Corporation each filed separate motions to dismiss. On October 24, 2019, the District Court denied Cleco Power’s motion as premature and ruled that Saulsbury Industries, Inc. had six weeks to conduct discovery on specified jurisdictional issues. The Magistrate Judge presiding over the Western District of Louisiana consolidated cases issued a report and recommendation to the District Judge that the case instituted by Saulsbury Industries, Inc. be dismissed without prejudice and the case initiated by Cleco Power be remanded to the Ninth Judicial District Court for Rapides Parish. Saulsbury Industries, Inc. did not oppose the Magistrate Judge’s report and recommendation, and the District Judge issued a ruling that adopted the Magistrate Judge’s report and recommendation, which included reasoning consistent with Cleco Power’s arguments. Thus, the federal consolidated cases are now closed. On October 10, 2019, Cleco Power was served with a summons in Saulsbury Industries, Inc. v. Cabot Corporation and Cleco Power LLC in the 16 th Judicial District Court for St. Mary Parish. Saulsbury Industries, Inc. asserted the same claim as the Western District litigation and further asserts claims for payment on an open account. On December 9, 2019, Cleco Power moved to stay the case, arguing that the Rapides Parish suit should proceed. On February 14, 2020, the court granted Cleco Power’s motion. The 16 th Judicial District Court for the St. Mary Parish case held a hearing on October 16, 2020, and the judge granted Cleco Power’s declinatory exceptions of lis pendens. Thus, the St. Mary’s Parish case has been dismissed. Saulsbury appealed this decision. On May 17, 2022, the Court of Appeal, First Circuit, ruled in favor of Cleco Power and affirmed the decision of the 16 th Judicial District Court for St. Mary Parish with respect to Cleco Power. However, the First Circuit Court reversed the 16 th Judicial District Court for St. Mary Parish’s decision dismissing Cabot Corporation from the St. Mary Parish case. All parties filed applications for rehearing, which were denied on June 29, 2022. Cabot Corporation applied for review by the Louisiana Supreme Court of the portion of the First Circuit Court's ruling that denied Cabot Corporation’s exception seeking dismissal from the St. Mary Parish litigation. On November 1, 2022, the Louisiana Supreme Court rendered a decision in favor of Cabot Corporation. The Louisiana Supreme Court’s decision reversed the First Circuit Court’s decision and reinstated the decision of the 16 th Judicial District Court granting Cabot Corporation’s declinatory exceptions of lis pendens. The St. Mary Parish case has been dismissed in full. The stay was lifted in the Rapides Parish case and the Rapides Parish case is proceeding. The parties are currently participating in discovery. LPSC Audits and Reviews Fuel Audits Generally, Cleco Power’s cost of fuel used for electric generation and the cost of purchased power are recovered through the LPSC-established FAC that enables Cleco Power to pass on to its customers substantially all such expenses. Recovery of FAC costs is subject to periodic fuel audits by the LPSC, which are performed at least every other year. In January 2023, Cleco Power received a notice of audit from the LPSC for the period of January 2020 to December 2022. The total amount of fuel expense included in the audit is $1.10 billion. Cleco Power has responded to the first set of LPSC data requests. Cleco Power has FAC filings for January 2023 and thereafter that remain subject to audit. Management is unable to predict or give a reasonable estimate of the possible range of the disallowance, if any, related to these filings. Historically, the disallowances have not been material. If a disallowance of fuel cost is ordered resulting in a refund, any such refund could have a material adverse effect on the results of operations, financial condition, or cash flows of the Registrants. In March 2021, Cleco Power received approval from the LPSC to recover $50.0 million of incremental fuel and purchased power costs incurred as a result of Winter Storms Uri and Viola over a period of 12 months beginning with the May 2021 bills. In May 2021, Cleco Power received notice of an audit from the LPSC for the fuel costs incurred during the time period required to restore services to Cleco Power’s customers during Winter Storms Uri and Viola. On March 27, 2023, Cleco Power received a draft audit report from the LPSC indicating no material findings. Management expects the draft audit report to be approved in the fourth quarter of 2023. Environmental Audit In 2009, the LPSC approved Cleco Power to recover certain costs of environmental compliance through an EAC. The costs eligible for recovery are those for prudently incurred air emissions credits associated with complying with federal, state, and local air emission regulations that apply to the generation of electricity reduced by the sale of such allowances. Also eligible for recovery are variable emission mitigation costs, which are the costs of reagents such as ammonia and limestone that are a part of the fuel mix used to reduce air emissions, among other things. In April 2023, Cleco Power received a notice of audit from the LPSC for the period of January 2020 to December 2022. The total amount of environmental fuel expense included in the audit is $38.3 million. In October 2023, Cleco Power received a draft audit report from the LPSC indicating no material findings. Cleco Power has EAC filings for January 2023 and thereafter that remain subject to audit. Management is unable to predict or give a reasonable estimate of the possible range of the disallowance, if any, related to these filings. Historically, the disallowances have not been material. If a disallowance of environmental cost is ordered resulting in a refund to Cleco Power’s customers, any such refund could have a material adverse effect on the results of operations, financial condition, or cash flows of the Registrants. Cleco Power incurs environmental compliance expenses for reagents associated with the compliance standards of MATS. These expenses are also eligible for recovery through Cleco Power’s EAC and are subject to periodic review by the LPSC. In May 2020, the EPA finalized a rule that concluded that it is not appropriate and necessary to regulate hazardous air pollutants from coal- and oil-fired electric generating units. However, the EPA concluded that coal- and oil-fired electric generating units would not be removed from the list of regulated sources of hazardous air pollutants and would remain subject to MATS. The EPA also determined that the results of its risk and technology review did not require any revisions to the emissions standards. Several petitions for review of the rule’s findings were filed between May and July 2020 in the D.C. Circuit Court of Appeals. On January 20, 2021, the Presidential Administration issued an executive order, which directs federal agency heads to review regulations and other actions from the past four years to determine if they are inconsistent with the policies announced in the executive order. The order specifically directed the EPA to consider issuing a proposed rule to suspend, revise, or rescind the rule. The EPA determined the most environmentally protective course is to implement the rules in the executive order. On March 6, 2023, the EPA published in the Federal Register a final rule that reinstates the April 25, 2016, finding that it is appropriate and necessary to regulate hazardous air pollutants from coal and oil-fired electric generating units through MATS. On April 24, 2023, the EPA published in the Federal Register proposed amendments to MATS that are the result of the EPA’s review of the May 2020 residual risk and technology review of MATS. Management is unable to determine whether the outcome of the D.C. Circuit Court of Appeals’ review or the EPA’s review of the rule as a result of the executive order will result in changes to the MATS standards. Energy Efficiency Audit In 2013, the LPSC issued a General Order adopting rules promoting energy efficiency programs. Cleco Power began participating in energy efficiency programs in November 2014. Through an approved rate tariff, Cleco Power recovered $8.5 million and $6.8 million for the 2022 and 2021 program years, respectively. In September 2023, Cleco Power received a notice of audit from the LPSC for the program years 2021 and 2022. Cleco Power has received the first set of LPSC data requests. Program years 2023 and thereafter are subject to audit. Management is unable to predict or give a reasonable estimate of the outcome of this or any future audits. Dolet Hills Prudency Review Cleco Power is seeking recovery for stranded and decommissioning costs associated with the retirement of the Dolet Hills Power Station as well as deferred fuel and other mine-related closure costs. Recovery of these costs is subject to a prudency review by the LPSC, which is currently in progress. Cleco Power believes these costs are prudent and recoverable. However, initial testimony filed by the LPSC Staff advisors in August 2022 indicates disagreement with the recoverability of these incurred costs, quantifying up to $217.0 million of related costs as potentially imprudent. Cleco Power filed rebuttal testimony in September 2022 rebutting the LPSC Staff’s testimony. A hearing was held in May 2023, with the outcome pending. Due to the nature of the regulatory process, Cleco Power is currently unable to determine the timing of this process and if any portion of the incurred costs will be disallowed for recovery. Cleco Power continues to assert that recovery of those costs is probable; however, management is seeking a potential settlement to resolve this matter and move forward with the securitization process. South Central Generating Prior to the Cleco Cajun Transaction, South Central Generating was involved in various litigation matters, including environmental and contract proceedings, before various courts regarding matters arising out of the ordinary course of business. Management is unable to estimate any potential losses Cleco may be ultimately responsible for with respect to any of the remaining matters. As part of the Cleco Cajun Transaction, NRG Energy indemnified Cleco for losses as of the closing date associated with certain matters that existed as of the closing date, including pending litigation. Other Cleco is involved in various litigation matters, including regulatory, environmental, and administrative proceedings before various courts, regulatory commissions, arbitrators, and governmental agencies regarding matters arising in the ordinary course of business. The liability Cleco may ultimately incur with respect to any one of these matters may be in excess of amounts currently accrued. Management regularly analyzes current information and, as of September 30, 2023, believes the probable and reasonably estimable liabilities based on the eventual disposition of these matters are $8.1 million. Cleco has accrued this amount. Off-Balance Sheet Commitments and Guarantees Cleco Holdings and Cleco Power have entered into various off-balance sheet commitments, in the form of guarantees and standby letters of credit, in order to facilitate their activities and the activities of Cleco Holdings’ subsidiaries and equity investees (affiliates). Cleco Holdings and Cleco Power have also agreed to contractual terms that require the Registrants to pay third parties if certain triggering events occur. These contractual terms generally are defined as guarantees. Cleco Holdings entered into these off-balance sheet commitments in order to entice desired counterparties to contract with its affiliates by providing some measure of credit assurance to the counterparty in the event Cleco’s affiliates do not fulfill certain contractual obligations. If Cleco Holdings had not provided the off-balance sheet commitments, the desired counterparties may not have contracted with Cleco’s affiliates, or may have contracted with them at terms less favorable to its affiliates. The off-balance sheet commitments are not recognized on Cleco’s and Cleco Power’s Condensed Consolidated Balance Sheets because management has determined that Cleco’s and Cleco Power’s affiliates are able to perform the obligations under their contracts and that it is not probable that payments by Cleco or Cleco Power will be required. Cleco Holdings provided guarantees and indemnities to Entergy Louisiana and Entergy Gulf States as a result of the sale of the Perryville generation facility in 2005. The remaining indemnities relate to environmental matters that may have been present prior to closing. These remaining indemnities have no time limitations. The maximum amount of the potential payment to Entergy Louisiana and Entergy Gulf States is $42.4 million. Management does not expect to be required to pay Entergy Louisiana and Entergy Gulf States under these guarantees. On behalf of Acadia, Cleco Holdings provided guarantees and indemnities as a result of the sales of Acadia Unit 1 to Cleco Power and Acadia Unit 2 to Entergy Louisiana in 2010 and 2011, respectively. The remaining indemnities relate to the fundamental organizational structure of Acadia. These remaining indemnities have no time limitations or maximum potential future payments. Management does not expect to be required to pay Cleco Power or Entergy Louisiana under these guarantees. Cleco Holdings provided indemnities to Cleco Power as a result of the transfer of Coughlin to Cleco Power in March 2014. Cleco Power also provided indemnities to Cleco Holdings as a result of the transfer of Coughlin to Cleco Power. The maximum amount of the potential payment to Cleco Power and Cleco Holdings, for their respective indemnities is $40.0 million, except for indemnities relating to the fundamental organizational structure of each respective entity, of which the maximum amount is $400.0 million. Management does not expect to be required to make any payments under these indemnities. As part of the Amended Lignite Mining Agreement, Cleco Power and SWEPCO, joint owners of the Dolet Hills Power Station, have agreed to pay the loan and lease principal obligations of the lignite miner, DHLC, when due if DHLC does not have sufficient funds or credit to pay. Any amounts projected to be paid would be based on the forecasted loan and lease obligations to be incurred by DHLC, primarily for reclamation obligations. As of September 30, 2023, Cleco Power does not expect any payments to be made under this guarantee. Cleco Power has the right to dispute the incurrence of such loan and lease obligations through the review of the mining reclamation plan before the incurrence of such obligations. The Amended Lignite Mining Agreement does not affect the amount the Registrants can borrow under their credit facilities. In April 2020, Cleco Power and SWEPCO mutually agreed not to develop additional mining areas for future lignite extraction and subsequently provided notice to the LPSC of the intent to cease mining at the Dolet Hills and Oxbow mines by June 2020. The mine closures are subject to LPSC review and approval. As of June 30, 2020, all lignite reserves intended to be extracted from the mines had been extracted. On October 6, 2020, Cleco Power and SWEPCO made a joint filing with the LPSC seeking authorization to close the Oxbow mine and to include and defer certain accelerated mine closing costs in fuel and related ratemaking treatment. For more information on the LPSC prudency review associated with the mine closure costs, see “— LPSC Audits and Reviews — Dolet Hills Prudency Review.” Cleco has letters of credit to MISO pursuant to energy market requirements. The letters of credit automatically renew each year and have no impact on Cleco Holdings’ or Cleco Power’s revolving credit facility. Generally, neither Cleco Holdings nor Cleco Power has recourse that would enable them to recover amounts paid under their guarantee or indemnification obligations. There are no assets held as collateral for third parties that either Cleco Holdings or Cleco Power could obtain and liquidate to recover amounts paid pursuant to the guarantees or indemnification obligations. Other Commitments Cleco has accrued for liabilities related to third parties, employee medical benefits, and AROs. In April 2015, the EPA published a final rule in the Federal Register for regulating the disposal and management of CCRs from coal-fired power plants (CCR Rule). The CCR Rule established extensive requirements for existing and new CCR landfills and surface impoundments and all lateral expansions consisting of location restrictions, design and operating criteria, groundwater monitoring and corrective action, closure requirements and post closure care, and recordkeeping, notification, and internet posting requirements. In August 2018, the D.C. Court of Appeals vacated several requirements in the CCR regulation, which included eliminating the previous acce ptability of compacted clay material as a liner for impoundments. As a result, in August 2020, the EPA published a final rule in the Federal Register that would set deadlines for costly modifications including retrofitting of clay-lined impoundments with compliant liners or closure of the impoundments. In November 2020, demonstrations were submitted to the EPA specifying an intended course of action for the ash disposal facilities at Big Cajun II, Rodemacher Unit 2, and the Dolet Hills Power Station in order to comply with the final CCR Rule. On January 11, 2022, Cleco Power and Cleco Cajun received communication from the EPA that the demonstrations had been deemed complete. Cleco Power withdrew the Dolet Hills demonstration due to the cessation of receiving waste. The two remaining demonstrations are still subject to EPA approval based on pending technical review. At March 31, 2023, Cleco Cajun recorded a decrease of $19.5 million in its ARO balance due to revised cost estimates. Cleco Cajun’s ARO is recorded in Liabilities held for sale on Cleco’s Condensed Consolidated Balance Sheet. As part of the Cleco Cajun Transaction, NRG Energy agreed to indemnify Cleco for certain environmental costs up to $25.0 million associated with the CC R Rule, for both ARO and non-ARO related expenses. At September 30, 2023, Cleco Cajun had an indemnification asset totaling $18.0 million, which was substantially related to AROs associated with ash pond remediation. This asset is recorded in Assets held for sale on Cleco’s Condensed Consolidated Balance Shee t. As additional periodic expenses related to covered costs are incurred, the associated indemnification asset will be recognized. The indemnification asset is expected to be collected as indemnified costs, either recognized in the ARO or as periodic expenses, are incurred. Risks and Uncertainties Cleco could be subject to possible adverse consequences if Cleco’s counterparties fail to perform their obligations or if Cleco or its affiliates are not in compliance with loan agreements or bond indentures. Access to capital markets is a significant source of funding for both short- and long-term capital requirements not satisfied by operating cash flows. Changes in the regulatory environment or market forces could cause Cleco to determine its assets have suffered an other-than-temporary decline in value, whereby an impairment would be required, and Cleco’s financial condition could be materially adversely affected.

Goodwill and Intangible Assets Disclosure [Abstract]
Intangible Assets and Goodwill	Note 16 — Intangible Assets and Goodwill Securitized Intangible Asset On June 22, 2022, Cleco Securitization I acquired the Storm Recovery Property from Cleco Power for a purchase price of $415.9 million. The Storm Recovery Property is classified as a securitized intangible asset on Cleco’s and Cleco Power’s Condensed Consolidated Balance Sheets. This securitized intangible asset is being amortized ratably each period consistent with actual collections of the asset’s portion of the revenue requirement billed to Cleco Power’s customers. Amortization is included in Depreciation and amortization on Cleco’s and Cleco Power’s Condensed Consolidated Statements of Income. During the three and nine months ended September 30, 2023, amortization expense of $5.1 million and $10.7 million, respectively, was recognized. At the end of its life, this securitized intangible asset will have no residual value. The following table summarizes the balance of the securitized intangible asset subject to amortization included on Cleco’s and Cleco Power’s Condensed Consolidated Balance Sheets: (THOUSANDS) AT SEPT. 30, 2023 AT DEC. 31, 2022 Storm Recovery Property intangible asset $ 415,946 $ 415,946 Accumulated amortization (13,502) (2,823) Net intangible asset subject to amortization $ 402,444 $ 413,123 Other Intangible Assets As a result of the 2016 Merger, fair value adjustments were recorded on Cleco’s Condensed Consolidated Balance Sheet for the valuation of finite intangible assets relating to long-term wholesale power supply agreements. At the end of their lives, these power supply agreement intangible assets will have no residual value. The intangible assets related to the power supply agreements are amortized over the estimated life of each applicable contract ranging between 8 and 19 years, and the amortization is included in Electric operations on Cleco’s Condensed Consolidated Statements of Income. The following table presents the amortization expense recognized during the three and nine months ended September 30, 2023, and 2022: Cleco FOR THE THREE MONTHS ENDED SEPT. 30, FOR THE NINE MONTHS ENDED SEPT. 30, (THOUSANDS) 2023 2022 2023 2022 Amortization expense Power supply agreements $ 2,323 $ 2,420 $ 7,131 $ 7,260 The following table summarizes the balance of other intangible assets subject to amortization included in Cleco’s Condensed Consolidated Balance Sheets: Cleco (THOUSANDS) AT SEPT. 30, 2023 AT DEC. 31, 2022 Power supply agreements $ 85,104 $ 85,104 Accumulated amortization (72,148) (65,018) Net intangible assets subject to amortization $ 12,956 $ 20,086 Goodwill On April 13, 2016, in connection with the completion of the 2016 Merger, Cleco recognized goodwill of $1.49 billion. Management assigned the recognized goodwill to the Cleco Power reporting unit. Goodwill is required to be tested for impairment at the reporting unit level on an annual basis or whenever events or circumstances indicate that the value of goodwill may be impaired. In performing the impairment test, Cleco compares the fair value of the reporting unit to its carrying value including goodwill. If the carrying value including goodwill were to exceed the fair value of a reporting unit, an impairment loss would be recognized. A goodwill impairment loss is measured as the amount by which a reporting unit's carrying value exceeds fair value, not to exceed the carrying amount of goodwill. Cleco estimates the reporting unit's fair value 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. The income approach cash flow valuations involve a number of estimates that require broad assumptions and significant judgment by management regarding future performance, including estimation of future cash flows related to capital expenditures, the weighted average cost of capital or discount rate and the assumed long-term growth rate approach, which incorporates management's assumptions regarding sustainable long-term growth. The market approach includes significant assumptions around the implied market multiples for certain peer companies. Management selects comparable peers based on each peer’s primary business mix, operations, and market capitalization compared to the applicable reporting unit and calculates implied market multiples based on available projected earnings guidance and peer company market values as of the test date. Cleco performs an annual impairment test each August. In between annual tests, Cleco monitors its estimates and assumptions regarding estimated future cash flows, including the impact of movements in market indicators in future quarters, and will update the impairment analyses if a triggering event occurs. While Cleco believes the assumptions are reasonable, actual results may differ from projections. To the extent cash flows, long-term growth rates, U.S. Treasury rates, or other factors outside of Cleco’s control may impact Cleco’s projected results, Cleco may be required to reduce all or a portion of the carrying value of goodwill. Cleco conducted its 2023 annual impairment test using an August 1, 2023, measurement date and determined that the estimated fair value of the reporting unit exceeded its carrying value, and no impairment existed.

Accounting Policies [Abstract]
Discontinued Operations	In 2022, Cleco Holdings engaged in a strategic review process related to its investment in Cleco Cajun. In March 2023, Cleco Holdings’ management, with the support of its Board of Managers, committed to a plan of action for the disposition of the Cleco Cajun Sale Group, with a sale probable and subject to customary regulatory and Board of Managers approvals. As a result, Cleco Holdings’ management determined that the criteria under GAAP for the Cleco Cajun Sale Group to be classified as held for sale were met and a sale will represent a strategic shift that will have a major effect on Cleco’s future operations and financial results. Therefore, the Cleco Cajun Sale Group is presented as discontinued operations. The financial information for historical periods provided in this report has been recast to present the results of operations and financial position of the Cleco Cajun Sale Group as discontinued operations. Cleco has elected to present cash flows of discontinued operations combined with cash flows of continuing operations. Unless otherwise noted, the notes to these condensed consolidated financial statements exclude amounts related to discontinued operations, assets held for sale, and liabilities held for sale for all periods presented.
Principles of Consolidation	The accompanying condensed consolidated financial statements of Cleco include the accounts of Cleco and its majority-owned subsidiaries after elimination of intercompany accounts and transactions.Following the formation of Cleco Securitization I and the closing of the storm recovery securitization financing on June 22, 2022, Cleco Power became the primary beneficiary of Cleco Securitization I, and as a result, the financial statements of Cleco Securitization I are consolidated with the financial statements of Cleco Power.
Basis of Presentation	The condensed consolidated financial statements of Cleco and Cleco Power have been prepared in accordance with GAAP for interim financial information and with the instructions to Form 10-Q and Regulation S-X. Accordingly, these condensed consolidated financial statements do not include all of the information and notes required by GAAP for annual financial statements. The year-end condensed consolidated balance sheet data was derived from audited financial statements and adjusted for discontinued operations. Because the interim condensed consolidated financial statements and the accompanying notes do not include all of the information and notes required by GAAP for annual financial statements, the condensed consolidated financial statements and other information included in this Quarterly Report on Form 10-Q should be read in conjunction with the consolidated financial statements and accompanying notes in the Registrants’ Combined Annual Report on Form 10-K for the fiscal year ended December 31, 2022. These condensed consolidated financial statements, in the opinion of management, reflect all normal recurring adjustments that are necessary for a fair statement of the financial position and results of operations of Cleco and Cleco Power. Amounts reported in Cleco’s and Cleco Power’s interim financial statements are not necessarily indicative of amounts expected for the annual periods due to the effects of seasonal temperature variations on energy consumption, regulatory rulings, the timing of maintenance on electric generating units, changes in mark-to-market valuations, changing commodity prices, discrete income tax items, and other factors. In preparing financial statements that conform to GAAP, management must make estimates and assumptions that affect the reported amounts of assets and liabilities, the reported amounts of revenues and expenses, and the disclosure of contingent assets and liabilities at the date of the financial statements. Actual results could differ from those
Restricted Cash and Cash Equivalents	Various agreements to which Cleco is subject contain covenants that restrict its use of cash. As certain provisions under these agreements are met, cash is transferred out of related escrow accounts and becomes available for its intended purposes and/or general corporate purposes.
Reserves for Credit Losses	Customer accounts receivable are recorded at the invoiced amount and do not bear interest. Customer accounts receivable are generally considered to become past due 20 days after the billing date. Cleco recognizes write-offs within the allowance for credit losses once all recovery methods have been exhausted. It is the policy of management to review accounts receivable and unbilled revenue monthly using a reserve matrix based on historical bad debt write-offs, as well as current and forecasted economic conditions, to establish a credit loss estimate. Management’s historical credit loss analysis included periods of economic recessions, natural disasters, and temporary changes to collection policies. Due to the critical necessity of electricity, none of these past events have significantly impacted Cleco’s credit loss rates. As a result of the market price volatility of natural gas throughout 2022, Cleco experienced significant increases to the pass-through fuel component of retail customer energy bills. Due to these increased customer costs, along with the impacts of a 40-year high inflation rate, Cleco experienced increases in credit loss reserves. These factors have not been and are not expected to be material to Cleco’s results of operations, financial condition, or cash flows. During the third quarter of 2023, Cleco's service territory experienced sustained record high temperatures resulting in an increase in usage by its customers. In anticipation of higher customer costs and high heat conditions, Cleco temporarily suspended disconnections and the utilization of collection agencies for the month of August and most of September 2023, resulting in no additional charge-offs during these months. On September 25, 2023, Cleco resumed disconnection and collection activities. Although Cleco’s service territory experienced various external impacts, Cleco’s credit losses at September 30, 2023, were still within range of its historical credit loss analysis.
Recent Authoritative Guidance	In March 2023, FASB issued guidance that applies to leases between entities under common control. The guidance provides a practical expedient for determining whether an arrangement between entities under common control is a lease as well as the classification of the lease. In addition, the leasehold improvements amortization period is to be determined by the useful life to the common group rather than the term of the lease. The new guidance is effective for fiscal years beginning after December 15, 2023, including interim periods within those fiscal years. Cleco has arrangements between entities under common control and management is evaluating the impacts of this guidance on the results of operations, financial condition, and cash flows of the Registrants.
Regulatory Assets and Liabilities	Cleco Power recognizes an asset for certain costs capitalized or deferred for recovery from customers and recognizes a liability for amounts expected to be returned to customers or collected for future expected costs. Cleco Power records these assets and liabilities based on regulatory approval and management’s ongoing assessment that it is probable these items will be recovered or refunded through the ratemaking process. Under the current regulatory environment, Cleco Power believes these regulatory assets will be fully recoverable;
Pension Plan and Employee Benefits	Employees hired before August 1, 2007, are covered by a non-contributory, defined benefit pension plan. Based on the funding assumptions at December 31, 2022, management estimates that pension contributions totaling $74.5 million will be required through 2027. Cleco expects to make a $25.7 million minimum required contribution to the pension plan in 2024. Cleco is not required to make any contributions to the pension plan in 2023. Cleco Power is the plan sponsor and Support Group is the plan administrator. Benefits under the plan reflect an employee’s years of service, age at retirement, and accrued benefit at retirement. Cleco’s retirees may be eligible to receive Other Benefits. Dependents of Cleco’s retirees may also be eligible to receive Other Benefits with the exception of life insurance benefits.
Income Taxes	Cleco classifies all interest related to uncertain tax positions as a component of interest payable and interest expense.Cleco classifies income tax penalties as a component of other expense.
Variable Interest Entities	Cleco and Cleco Power apply the equity method of accounting to report the investment in Oxbow in the consolidated financial statements. Under the equity method, the assets and liabilities of this entity are reported as Equity investment in investee on Cleco’s and Cleco Power’s Condensed Consolidated Balance Sheets. The revenue and expenses (excluding income taxes) of this entity are netted and reported as equity income or loss from investees on Cleco’s and Cleco Power’s Condensed Consolidated Statements of Income.

Schedule of Intangible Assets Subject to Amortization	The following table summarizes the balance of other intangible assets subject to amortization included in Cleco’s Condensed Consolidated Balance Sheets: Cleco (THOUSANDS) AT SEPT. 30, 2023 AT DEC. 31, 2022 Power supply agreements $ 85,104 $ 85,104 Accumulated amortization (72,148) (65,018) Net intangible assets subject to amortization $ 12,956 $ 20,086 Goodwill On April 13, 2016, in connection with the completion of the 2016 Merger, Cleco recognized goodwill of $1.49 billion. Management assigned the recognized goodwill to the Cleco Power reporting unit. Goodwill is required to be tested for impairment at the reporting unit level on an annual basis or whenever events or circumstances indicate that the value of goodwill may be impaired. In performing the impairment test, Cleco compares the fair value of the reporting unit to its carrying value including goodwill. If the carrying value including goodwill were to exceed the fair value of a reporting unit, an impairment loss would be recognized. A goodwill impairment loss is measured as the amount by which a reporting unit's carrying value exceeds fair value, not to exceed the carrying amount of goodwill. Cleco estimates the reporting unit's fair value 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. The income approach cash flow valuations involve a number of estimates that require broad assumptions and significant judgment by management regarding future performance, including estimation of future cash flows related to capital expenditures, the weighted average cost of capital or discount rate and the assumed long-term growth rate approach, which incorporates management's assumptions regarding sustainable long-term growth. The market approach includes significant assumptions around the implied market multiples for certain peer companies. Management selects comparable peers based on each peer’s primary business mix, operations, and market capitalization compared to the applicable reporting unit and calculates implied market multiples based on available projected earnings guidance and peer company market values as of the test date. Cleco performs an annual impairment test each August. In between annual tests, Cleco monitors its estimates and assumptions regarding estimated future cash flows, including the impact of movements in market indicators in future quarters, and will update the impairment analyses if a triggering event occurs. While Cleco believes the assumptions are reasonable, actual results may differ from projections. To the extent cash flows, long-term growth rates, U.S. Treasury rates, or other factors outside of Cleco’s control may impact Cleco’s projected results, Cleco may be required to reduce all or a portion of the carrying value of goodwill. Cleco conducted its 2023 annual impairment test using an August 1, 2023, measurement date and determined that the estimated fair value of the reporting unit exceeded its carrying value, and no impairment existed.
