Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Note 1 — Summary of Significant Accounting Policies COVID-19 Impacts In March 2020, WHO declared the outbreak of COVID-19 to be a global pandemic, and the U.S. declared a national emergency. In response to these declarations and the rapid spread of COVID-19, federal, state and local governments imposed varying degrees of restrictions on business and social activities to contain COVID-19, including quarantine and “stay-at-home” orders and directives in Cleco’s service territory. State and local authorities also subsequently implemented multistep policies to reopen various sectors of the economy such as retail establishments, health and personal care businesses, and restaurants, among others. During March and April 2021, due to the reduction in new COVID-19 cases and hospitalizations and the availability of COVID-19 vaccines, the governor of the state of Louisiana reduced restrictions that were previously in effect, eased capacity limits on businesses and social gatherings, and revoked the mandatory, state-wide mask mandate. However, effective August 4, 2021, the state-wide mask mandate was reinstated due to a surge in COVID-19 cases. The COVID-19 pandemic may worsen in the U.S. during the upcoming months, which may cause federal, state, and local governments to reconsider restrictions on business and social activities. In the event governments reinstate or increase restrictions, the reopening of the economy may be further curtailed. Cleco has modified some of its business operations, as these restrictions have significantly impacted many sectors of the economy. Impacts include record levels of unemployment, with businesses, nonprofit organizations, and governmental entities modifying, curtailing, or ceasing normal operations. Cleco is monitoring the ongoing COVID-19 pandemic and continues to adjust certain business practices to conform to government restrictions and best practices encouraged by the CDC, WHO, and other governmental and regulatory authorities. 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. 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. 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, 2020. These condensed consolidated financial statements, in the opinion of management, reflect all normal recurring adjustments that are necessary to fairly state the financial position and results of operations of Cleco and Cleco Power. Amounts reported in Cleco 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 estimates. For information on recent authoritative guidance and its effect on financial results, see Note 2 — “Recent Authoritative Guidance.” 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. Cleco and Cleco Power’s restricted cash and cash equivalents consisted of the following: Cleco (THOUSANDS) AT JUNE 30, 2021 AT DEC. 31, 2020 Current Cleco Katrina/Rita’s storm recovery bonds $ 1,673 $ 2,626 Cleco Power’s charitable contributions 1,078 1,718 Cleco Power’s rate credit escrow 198 201 Total current 2,949 4,545 Non-current Diversified Lands’ mitigation escrow 22 22 Cleco Cajun’s defense fund 722 722 Total non-current 744 744 Total restricted cash and cash equivalents $ 3,693 $ 5,289 Cleco Power (THOUSANDS) AT JUNE 30, 2021 AT DEC. 31, 2020 Current Cleco Katrina/Rita’s storm recovery bonds $ 1,673 $ 2,626 Charitable contributions 1,078 1,718 Rate credit escrow 198 201 Total restricted cash and cash equivalents $ 2,949 $ 4,545 Prior to the repayment of the storm recovery bonds in March 2020, Cleco Katrina/Rita had the right to bill and collect storm restoration costs from Cleco Power’s customers. As cash was collected, it was restricted for payment of administrative fees, interest, and principal on the storm recovery bonds. The remaining $1.7 million of restricted cash relating to Cleco Katrina/Rita at June 30, 2021, will be used to benefit retail customers in a manner and timing as approved by the LPSC. 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. Although Cleco’s service territory experienced a recent decline in the economy in 2020 and 2021 primarily related to the COVID-19 pandemic and weather-related events, the economic outlook at June 30, 2021, was 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 FOR THE SIX MONTHS (THOUSANDS) ACCOUNTS OTHER* TOTAL ACCOUNTS OTHER* TOTAL Balances, beginning of period $ 2,040 $ 1,638 $ 3,678 $ 2,758 $ 1,638 $ 4,396 Current period provision 616 — 616 2,490 — 2,490 Charge-offs (1,583) — (1,583) (4,442) — (4,442) Recovery 261 — 261 528 — 528 Balances, June 30, 2021 $ 1,334 $ 1,638 $ 2,972 $ 1,334 $ 1,638 $ 2,972 * Loan held at Diversified Lands that was fully reserved for at June 30, 2021.

Accounting Changes and Error Corrections [Abstract]
Recent Authoritative Guidance	Note 2 — Recent Authoritative Guidance In March 2020, FASB issued optional guidance for a limited period of time that applies to entities meeting certain criteria for the contract modifications or hedging relationships that are referencing LIBOR or another reference rate expected to be discontinued due to reference rate reform. The guidance includes a general principal that permits an entity to consider contract modifications due to reference rate reform to be an event that does not require contract remeasurement at the modification date or reassessment of a previous accounting determination. The optional guidance may be applied from March 12, 2020, through December 31, 2022. Management has identified contracts with reference rates that will be discontinued, primarily related to long-term debt obligations. In the second quarter of 2021, certain debt contracts were amended to include fallback provisions that provide substitute reference rates upon the discontinuance of LIBOR, among other amendments. Management will continue to modify contracts to include similar fallback language and expects to apply this guidance on an ongoing basis. Management does not expect this guidance to have a significant impact on the Registrants’ results of operations, financial condition, or cash flows. In December 2019, FASB amended the guidance for accounting for income taxes. The amendments simplify the accounting for income taxes by removing certain exceptions to general principles included in the accounting guidance. Effective January 1, 2021, Cleco adopted the amended accounting guidance. Adoption of this guidance did not materially impact the Registrants’ results of operations, financial condition, or cash flows.

Regulated Operations [Abstract]
Regulatory Assets and Liabilities	Note 5 — Regulatory Assets and Liabilities Cleco Power capitalizes or defers certain costs for recovery from customers and recognizes a liability for amounts expected to be returned to customers 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’s ability to recover these regulatory assets would no longer be probable, then to the extent that such regulatory assets were determined not to be recoverable, Cleco Power would be required to write-down such assets. 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.

Accumulated Deferred Fuel In February 2021, Winter Storms Uri and Viola moved through Louisiana causing substantial damage to Cleco’s distribution assets, electricity generation supply shortages, natural gas supply shortages, and increases in wholesale prices of natural gas in the United States, primarily due to prolonged freezing temperatures. Incremental fuel and purchased power costs were incurred as a result of the winter storms. On March 29, 2021, Cleco Power received approval from the LPSC to recover $50.0 million of these costs through Cleco Power’s FAC over a period of 12 months beginning in May 2021. For more information about the incremental fuel and purchased power costs related to Winter Storms Uri and Viola, see Note 17 — “Storm Restoration — Winter Storms Uri and Viola.” Affordability Study On June 16, 2021, the LPSC approved Cleco Power’s new retail rate plan. As a result, Cleco Power was allowed to establish a regulatory asset of $13.6 million related to outside consulting fees for the assessment of Cleco Power’s practices and assistance in the identification of potential cost savings opportunities, while maintaining superior levels of employee safety, reliability, customer service, environmental stewardship, community involvement, and regulatory transparency. The regulatory asset is being amortized over 10 years beginning July 1, 2021. Deferred Storm Restoration Costs — Winter Storms In February 2021, Cleco Power’s service territory experienced extreme and unprecedented winter weather. On February 14, 2021, Winter Storm Uri reached Louisiana resulting in power outages for approximately 11,000 of Cleco Power’s electric customers located primarily in south Louisiana. On February 17, 2021, Winter Storm Viola reached Louisiana resulting in power outages for approximately 43,000 of Cleco Power’s electric customers located primarily in central and south Louisiana. On March 17, 2021, the LPSC approved utilities establishing a regulatory asset to track and defer non-capital expenses associated with these winter storms. For more information about Winter Storms Uri and Viola, see Note 17 — “Storm Restoration — Winter Storms Uri and Viola.” Dolet Hills Mine Closure Cost On March 17, 2021, the LPSC approved the establishment of a regulatory asset for lignite costs that exceeded $150 per ton that would otherwise be billed through Cleco Power’s FAC and any reasonable incremental third-party professional costs related to the closure of the mine. At June 30, 2021, Cleco Power had a regulatory asset of $13.9 million for these mine-related incurred costs. Madison Unit 3 Property Taxes On June 16, 2021, the LPSC approved Cleco Power’s new retail rate plan. As a result, beginning July 1, 2022, Cleco Power will be allowed to recover property taxes paid for Madison Unit 3, including a carrying charge at Cleco Power’s weighted average cost of capital, grossed up for taxes. At June 30, 2021, Cleco Power recorded a regulatory asset of $4.2 million for the accrued 2021 Madison Unit 3 property taxes. The amount included in the cost recovery mechanism each year will amortize over 12 months. Other On June 16, 2021, the LPSC approved Cleco Power’s new retail rate plan resulting in Cleco Power establishing several regulatory assets. Cleco Power was allowed to establish a regulatory asset to recover the undercollection of revenues related to the Northlake Transmission Agreement. At June 30, 2021, Cleco Power had $3.5 million recorded for this regulatory asset, which is being amortized over 12 months beginning July 1, 2021. In addition, the LPSC approved recovery of other previously deferred costs totaling $4.1 million which are being amortized over four years beginning July 1, 2021. These costs are primarily associated with Cleco Power’s recently approved base rate case. In June 2017 and prior to the approval of Cleco Power’s new retail rate plan, the LPSC approved the establishment of a regulatory asset upon the completion of the Coughlin Pipeline project for the revenue requirement associated with the project until Cleco Power’s new retail rate plan was approved. At June 30, 2021, Cleco Power had a regulatory asset of $5.4 million related to the deferred revenue associated with the Coughlin Pipeline project. As approved by the LPSC in Cleco Power’s new rate plan, the regulatory asset is being amortized over four years beginning July 1, 2021. St. Mary Clean Energy Center At June 30, 2021, Cleco Power had a regulatory asset of $7.0 million for revenue requirements related to the St. Mary Clean Energy Center. As approved by the LPSC in Cleco Power’s new retail rate plan, the regulatory asset is being amortized over four years beginning July 1, 2021.

Fair Value Disclosures [Abstract]
Fair Value Accounting	Note 6 — Fair Value Accounting The amounts reflected on Cleco and Cleco Power’s Condensed Consolidated Balance Sheets at June 30, 2021, and December 31, 2020, 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. 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. The following tables summarize the carrying value and estimated market value of Cleco and Cleco Power’s financial instruments not measured at fair value on Cleco and Cleco Power’s Condensed Consolidated Balance Sheets: Cleco AT JUNE 30, 2021 AT DEC. 31, 2020 (THOUSANDS) CARRYING FAIR VALUE CARRYING FAIR VALUE Long-term debt $ 3,226,952 $ 3,509,555 $ 3,230,500 $ 3,541,349 * The carrying value of long-term debt does not include deferred issuance costs of $12.8 million at Cleco Power AT JUNE 30, 2021 AT DEC. 31, 2020 (THOUSANDS) CARRYING FAIR VALUE CARRYING FAIR VALUE Long-term debt $ 1,495,101 $ 1,772,243 $ 1,494,947 $ 1,794,799 * The carrying value of long-term debt does not include deferred issuance costs of $6.9 million at In order to fund capital requirements, Cleco issues 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. Fair Value Measurements and Disclosures Cleco classifies assets and liabilities that are measured at their fair value according to three different levels depending on the inputs used in determining fair value. Cleco elects not to designate derivatives as cash flow or fair value hedges, as allowed by accounting guidance. Cleco utilizes a mark-to-market approach recognizing changes in the fair value of FTRs and other commodity derivatives at Cleco Cajun in earnings and changes in the fair value of FTRs at Cleco Power as a component of deferred fuel assets and liabilities. Cleco utilizes different valuation techniques for fair value measurements under a fair value hierarchy. Assets and liabilities classified as Level 1 under the hierarchy utilize observable inputs that reflect quotable prices in active markets. Assets and liabilities classified as Level 2 are measured through proxy inputs of similar index or composite pricing. Assets and liabilities classified as Level 3 under the hierarchy are valued based on unobservable inputs, such as internally generated valuation models or valuations obtained in inactive markets where there is no readily available information. Cleco has consistently applied the Level 2 and Level 3 fair value techniques from fiscal period to fiscal period. Significant increases or decreases in any of those inputs in isolation would result in a significantly different fair value measurement. The assets and liabilities reported at fair value are grouped into classes based on the underlying nature and risks associated with the individual asset or liability. The following tables disclose for Cleco and Cleco Power the fair value of financial assets and liabilities measured on a recurring basis: Cleco FAIR VALUE MEASUREMENTS AT REPORTING DATE (THOUSANDS) AT JUNE 30, 2021 QUOTED PRICES SIGNIFICANT SIGNIFICANT AT DEC. 31, 2020 QUOTED PRICES SIGNIFICANT SIGNIFICANT Asset description Institutional money market funds $ 77,105 $ — $ 77,105 $ — $ 86,001 $ — $ 86,001 $ — FTRs 8,662 — — 8,662 4,805 — — 4,805 Other commodity derivatives* 55,834 — 55,834 — 8,599 — 8,599 — Total assets $ 141,601 $ — $ 132,939 $ 8,662 $ 99,405 $ — $ 94,600 $ 4,805 Liability description FTRs $ 1,161 $ — $ — $ 1,161 $ 1,625 $ — $ — $ 1,625 Other commodity derivatives* — — — — 1,612 — 1,612 — Total liabilities $ 1,161 $ — $ — $ 1,161 $ 3,237 $ — $ 1,612 $ 1,625 * Other commodity derivatives include fixed price physical forwards and swap transactions.

The following tables present the institutional money market funds in cash and cash equivalents and restricted cash and cash equivalents as recorded on Cleco and Cleco Power’s Condensed Consolidated Balance Sheets at June 30, 2021, and December 31, 2020: Cleco (THOUSANDS) AT JUNE 30, 2021 AT DEC. 31, 2020 Cash and cash equivalents $ 73,412 $ 80,712 Current restricted cash and cash equivalents $ 2,949 $ 4,545 Non-current restricted cash and cash equivalents $ 744 $ 744 Cleco Power (THOUSANDS) AT JUNE 30, 2021 AT DEC. 31, 2020 Cash and cash equivalents $ 16,112 $ 20,812 Current restricted cash and cash equivalents $ 2,949 $ 4,545 Institutional money market fund assets are discounted to the current period using a published U.S. Treasury interest rate as a proxy for a risk-free rate of return. If the money market funds 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 by either Cleco or Cleco Power. The Level 2 institutional money market funds asset consists of a single class. In order to capture interest income and minimize risk, cash is invested in money market funds that invest primarily in short-term securities issued by the U.S. Treasury to maintain liquidity and achieve the goal of a net asset value of a dollar. The risks associated with this class are counterparty risk of the fund manager and risk of price volatility associated with the underlying securities of the fund. Derivatives and other commodity contracts that do not qualify for derivative accounting treatment transacted directly with a counterparty and are not cleared on an exchange contain counterparty credit risk. Cleco may be required to provide credit support or pay liquidated damages with respect to any open trading contracts that Cleco has entered into or may enter into in the future. The amount of credit support that Cleco may be required to provide at any point in the future is dependent on the amount of the initial contract, changes in the market price, changes in open contracts, and changes in the amounts counterparties owe to Cleco. Changes in any of these factors could cause the amount of requested credit support to increase or decrease. Cleco Power and Cleco Cajun’s FTRs are valued using MISO’s monthly auction prices. Forward seasonal periods are not included in every monthly auction; therefore, the average of the most recent seasonal auction prices is used for monthly valuation. FTRs are categorized as Level 3 fair value measurements because the only relevant value available comes from MISO auctions, which occur monthly in the Multi-Period Monthly Auction. During the six months ended June 30, 2021, and the year ended December 31, 2020, Cleco did not experience any transfers between levels within the fair value hierarchy.

Retirement Benefits [Abstract]
Pension Plan and Employee Benefits	Note 8 — 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, 2020, and the funding relief provided by the American Rescue Plan Act, which was signed by the President on March 11, 2021, management estimates that no pension contributions will be required through 2025. As of June 30, 2021, Cleco expects to make $67.0 million in discretionary contributions to the pension plan in 2021, which would offset future required contributions. 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 and Cleco Power’s Condensed Consolidated Statements of Income. The components of net periodic pension and Other Benefits cost for the three and six months ended June 30, 2021, and 2020 were as follows: PENSION BENEFITS OTHER BENEFITS FOR THE THREE MONTHS ENDED JUNE 30, FOR THE THREE MONTHS ENDED JUNE 30, (THOUSANDS) 2021 2020 2021 2020 Components of periodic benefit costs Service cost $ 2,730 $ 2,582 $ 595 $ 508 Interest cost 4,719 5,278 323 410 Expected return on plan assets (5,698) (6,242) — — Amortizations Prior period service credit — (15) — — Net loss 5,607 4,477 384 340 Net periodic benefit cost $ 7,358 $ 6,080 $ 1,302 $ 1,258 PENSION BENEFITS OTHER BENEFITS FOR THE SIX MONTHS ENDED JUNE 30, FOR THE SIX MONTHS ENDED JUNE 30, (THOUSANDS) 2021 2020 2021 2020 Components of periodic benefit costs Service cost $ 5,258 $ 4,910 $ 1,190 $ 1,015 Interest cost 9,334 10,408 645 820 Expected return on plan assets (11,400) (12,487) — — Amortizations Prior period service credit — (30) — — Net loss 10,369 8,149 770 680 Net periodic benefit cost $ 13,561 $ 10,950 $ 2,605 $ 2,515 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 six months ended June 30, 2021, was $0.9 million and $1.8 million, respectively. The expense of the pension plan related to Cleco’s other subsidiaries for the three and six months ended June 30, 2020, was $1.3 million and $1.7 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 six months ended June 30, 2021, was $1.2 million and $2.4 million, respectively. The expense related to other benefits reflected in Cleco Power’s Condensed Consolidated Statements of Income for the three and six months ended June 30, 2020, was $1.2 million and $2.5 million, respectively. The current and non-current portions of the Other Benefits liability for Cleco and Cleco Power at June 30, 2021, and December 31, 2020, were as follows: Cleco (THOUSANDS) AT JUNE 30, 2021 AT DEC. 31, 2020 Current $ 4,463 $ 4,463 Non-current $ 51,522 $ 51,868 Cleco Power (THOUSANDS) AT JUNE 30, 2021 AT DEC. 31, 2020 Current $ 3,865 $ 3,865 Non-current $ 40,449 $ 40,734 SERP Certain Cleco officers are covered by SERP. Cleco does not fund the SERP liability, but instead pays for current benefits out of general funds available. Cleco Power has formed a rabbi trust. The life insurance policies issued on SERP participants designate the rabbi trust as the beneficiary. Market conditions could have a significant impact on the cash surrender value of the life insurance policies. Proceeds from the life insurance policies are expected to be used to pay the SERP participants’ death benefits, as well as future SERP payments. However, 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. All SERP benefits are paid out of general cash available of the respective companies that employed the officer. Cleco Power is the plan sponsor and Support Group is the plan administrator.

Income Tax Disclosure [Abstract]
Income Taxes	Note 9 — Income Taxes Effective Tax Rates The following tables summarize the effective income tax rates for Cleco and Cleco Power for the three and six months ended June 30, 2021, and 2020 : Cleco FOR THE THREE MONTHS FOR THE SIX MONTHS 2021 2020 2021 2020 Effective tax rate 11.1 % 23.9 % 0.4 % 23.4 % Cleco Power FOR THE THREE MONTHS FOR THE SIX MONTHS 2021 2020 2021 2020 Effective tax rate 24.6 % 24.9 % (1.7) % 24.1 % For the three and six months ended June 30, 2021, the effective income tax rates for both Cleco and Cleco Power were different than the federal statutory rate primarily due to the amortization of excess ADIT, adjustment to record tax expense at the projected annual effective tax rate, and state tax expense. For the three and six months ended June 30, 2020, the effective income tax rates for both Cleco and Cleco Power were different than the federal statutory rate primarily due to the adjustment to record tax expense at the projected annual effective tax rate; the flow through of tax benefits, including AFUDC equity; and state tax expense. Uncertain Tax Positions Cleco classifies all interest related to uncertain tax positions as a component of interest payable and interest expense. At June 30, 2021, and December 31, 2020, Cleco and Cleco Power had no liability for uncertain tax positions or interest payable related to uncertain tax positions. Cleco estimates that it is reasonably possible that the balance of unrecognized tax benefits as of June 30, 2021, for Cleco and Cleco Power would be unchanged in the next 12 months. The settlement of open tax years could involve the payment of additional taxes, and/or the recognition of tax benefits, which may have an effect on Cleco’s effective tax rate. 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 2017, 2018, and 2019, the IRS has completed its review of years 2017 through 2019, and these tax returns were filed consistent with the IRS’s review. The IRS has placed Cleco in the Bridge phase of the Compliance Assurance Process for the 2020 tax year. In this phase, the IRS will not accept any disclosures, conduct any reviews, or provide any assurances. The state income tax years 2017, 2018, and 2019 remain open to examination by the Louisiana Department of Revenue. Cleco classifies income tax penalties as a component of other expense. For the three and six months ended June 30, 2021, and 2020, no penalties were recognized. CARES Act In March 2020, the CARES Act was signed into law. The CARES Act includes tax relief provisions such as an alternative minimum tax credit refund, a five-year net operating loss carryback from years 2018 through 2020, and deferred payments of employer payroll taxes. Cleco deferred $6.0 million in employer payroll tax payments for the period March 27, 2020, through December 31, 2020. Cleco will pay $3.0 million of the obligation by December 31, 2021, and the remaining $3.0 million by December 31, 2022. Cleco Power deferred $3.6 million in employer payroll tax payments for the period March 27, 2020, through December 31, 2020. Cleco Power will pay $1.8 million of the obligation by December 31, 2021, and the remaining $1.8 million by December 31, 2022. The CARES Act also includes modifications on the limitations of business interest for the 2019 and 2020 tax years. The modifications increase the allowable business interest deduction from 30% to 50% of adjusted taxable income. Cleco does not anticipate having any disallowed interest for the 2020 tax year. Consolidated Appropriations Act of 2021 In December 2020, the Consolidated Appropriations Act of 2021 (CAA) was signed into law. The CAA includes COVID-19 tax relief and tax extender provisions including extensions of time to begin construction on and placed in-service assets generating production tax credits and income tax credits, 100% deductibility of business meals in 2021 and 2022, and an extension of the work opportunity tax credit. The income tax credit percentage has been increased for projects starting construction through 2023 and placed in service by the end of 2025. Management does not expect the CAA to have a material impact on the Registrants. American Jobs Act of 2021 On March 31, 2021, the President announced the American Jobs Act. This proposal includes a number of incentives to encourage construction of certain transmission and energy storage property. The proposed act also proposes to raise the federal statutory corporate income tax rate from 21% to 28% and to introduce a minimum tax based on book income. Currently, management is unable to predict the impact of the proposed act on the Registrants.

Segment Reporting [Abstract]
Disclosures about Segments	Note 10 — Disclosures about Segments Cleco’s reportable segments are based on its method of internal reporting, which disaggregates business units by its first-tier subsidiary. Cleco’s reportable segments are Cleco Power and Cleco Cajun. Each reportable segment engages in business activities from which it earns revenue and incurs expenses. 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 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 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, and an investment subsidiary. There were no changes to Cleco’s existing reportable segments. 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 segments. Management evaluates the performance of Cleco’s segments and allocates resources to them 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 and liabilities recorded for the fair value adjustment of wholesale power supply agreements as a result of the 2016 Merger and the Cleco Cajun Transaction, as well as amortization of deferred lease revenue resulting from the Cleco Cajun Transaction. Material intercompany transactions occur on a regular basis. These intercompany transactions relate primarily to joint and common administrative support services as well as transmission services provided by Cleco Power to Cleco Cajun.

Regulated Operations [Abstract]
Regulation and Rates	Note 11 — Regulation and Rates Provision for rate refund on Cleco and Cleco Power’s Condensed Consolidated Balance Sheets consisted primarily of the following: (THOUSANDS) AT JUNE 30, 2021 AT DEC. 31, 2020 FRP $ 2,392 $ 1,786 TCJA $ 2,057 $ 2,057 Cleco Katrina/Rita storm recovery charges $ 1,610 $ 1,617 Site-specific industrial customer $ 990 $ 710 Transmission ROE $ 250 $ 595 FERC audit $ — $ 1,912 FRP Prior to July 1, 2021, Cleco Power’s annual retail earnings were subject to an FRP established by the LPSC in June 2014. The 2014 FRP allowed Cleco Power to earn a target ROE of 10.0%, while providing the opportunity to earn up to 10.9%. Additionally, 60.0% of retail earnings between 10.9% and 11.75%, and all retail earnings over 11.75%, were required to be refunded to customers. In June 2019, Cleco Power filed an application with the LPSC for a new FRP. The FRP rates previously established remained in effect due to delays in the base rate case. On June 16, 2021, the LPSC approved Cleco Power’s new retail rate plan. Effective July 1, 2021, under the terms of the new 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. Cleco Power’s next base rate case is required to be filed with the LPSC on or before March 31, 2023. Cleco Power filed its monitoring report for the 12 months ended June 30, 2019, on October 31, 2019, indicating that no refund was due. On June 30, 2021, the LPSC Staff filed their report indicating agreement with Cleco Power’s refund calculation for the 12 months ending June 30, 2019. Cleco Power anticipates approval of the report from the LPSC in the third quarter of 2021. Monitoring reports for the 12 months ended June 30, 2020, and 2021 were not required due to the expiration of the 2014 FRP. The next monitoring report will be filed on or before October 31, 2022, for the 12 months ending June 30, 2022. Cleco Power continued to accrue the annual cost of service savings resulting from the 2016 Merger Commitments through June 30, 2021. Beginning July 1, 2021, the annual cost of service savings are included in Cleco Power’s new retail rate plan. At June 30, 2021, Cleco Power had $2.4 million accrued for the period July 1, 2019, through June 30, 2021. Cleco Power expects to refund its customers $1.2 million in September 2021 and September 2022. TCJA The provisions of the TCJA reduced the top federal statutory corporate income tax rate from 35% to 21%. As a result of the tax rate reduction, on January 1, 2018, Cleco Power began accruing an estimated reserve for the reduction in the federal statutory corporate income tax rate. In February 2018, the LPSC directed utilities, including Cleco Power, to provide considerations of the appropriate manner to flow through to ratepayers the benefits of the reduction in corporate income taxes as a result of the TCJA. In July 2019, the LPSC approved Cleco Power’s rate refund of $79.2 million, plus interest, for the reduction in the statutory federal tax rate for the period from January 2018 to June 2020. The refund was credited to customers over 12 months beginning August 1, 2019. In July 2019, the LPSC approved Cleco Power’s motion to address the rate redesign and the regulatory liability for excess ADIT, resulting from the enactment of the TCJA, in Cleco Power’s current base rate case. As a result of the delay in the rate case, on July 15, 2020, the LPSC approved Cleco Power’s application to extend the TCJA bill credits at the same rate as determined in the initial TCJA refund of approximately $7.0 million per month. The extension was for the period of August 2020 through November 2020. On November 13, 2020, Cleco Power again received approval for its application to extend the TCJA bill credits from November 30, 2020, until such a time that the rate case was completed. The $7.0 million monthly refund consisted of approximately $4.4 million, which was to be funded by the unprotected excess ADIT, and approximately $2.6 million, which is the change in the federal statutory corporate income tax rate from 35% to 21%. At June 30, 2021, Cleco Power had $2.1 million accrued for the estimated federal tax-related benefits from the TCJA. On June 16, 2021, the LPSC approved Cleco Power’s new retail rate plan which includes the settlement of the TCJA protected and unprotected excess ADIT. Effective July 1, 2021, all retail customers will continue 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 June 30, 2021, Cleco Power had $324.6 million accrued for the excess ADIT, of which $39.5 million is reflected in current regulatory liabilities. Cleco Katrina/Rita Storm Recovery Charges Prior to the repayment of the storm recovery bonds in March 2020, Cleco Katrina/Rita had the right to bill and collect storm restoration costs from Cleco Power’s customers to pay administrative fees, interest, and principal on the Cleco Katrina/Rita storm recovery bonds. Amounts remaining after the final principal and interest payments on the storm recovery bonds and payments for final administrative and winding up activities are subject to refund. At June 30, 2021, Cleco Power had $1.6 million accrued for Cleco Katrina/Rita storm recovery charges that are subject to refund. For more information on Cleco Katrina/Rita’s restricted cash, see Note 1 — “Summary of Significant Accounting Policies — Restricted Cash and Cash Equivalents.” Transmission ROE Two complaints were filed with FERC seeking to reduce the ROE component of the transmission rates that MISO transmission owners, including Cleco Power, may collect under the MISO tariff. As of June 30, 2021, Cleco Power h ad $0.3 million accrued for the change in ROE. For more information on the ROE complaints, see Note 13 — “Litigation, Other Commitments and Contingencies, and Disclosures about Guarantees — Litigation — Transmission ROE.” FERC Audit As of June 30, 2021, the estimated refund was fully refunded to Cleco Power’s wholesale transmission customers as a combination of refund payments and a reduction in Attachment O of the MISO tariff and grandfathered agreement rates over the preceding 12 months. For more information about the FERC audit, see Note 13 — “Litigation, Other Commitments and Contingencies, and Disclosures about Guarantees — Litigation — FERC Audit.” SSR In September 2016, Cleco Power filed an Attachment Y with MISO requesting retirement of Teche Unit 3 effective April 1, 2017. MISO conducted a study which determined the proposed retirement of Teche Unit 3 would result in violations of specific applicable reliability standards for which no mitigation is available. As a result, MISO designated Teche Unit 3 as an SSR unit until such time that an appropriate alternative solution could be implemented to mitigate reliability issues. One mitigating factor identified was Cleco Power’s Terrebonne to Bayou Vista Transmission project, which was completed in April 2019. Cleco Power received a termination notice, effective April 30, 2019, and filed paperwork to withdraw the filed Attachment Y. While operating as an SSR unit, Cleco Power received monthly payments that included recovery of expenses, including capital expenditures, related to the operations of Teche Unit 3. Additionally, MISO allocated SSR costs to the load serving entities that required the operation of the SSR unit, including Cleco Power. These payments and cost allocations were finalized as part of a MISO SSR settlement approved in December 2018. Cleco Power operated Teche Unit 3 as an SSR unit from April 2017 until April 2019. Cleco Power expects Teche Unit 3 to continue to be available to run and to continue to offer the unit into MISO through 2024, barring a significant unit failure. At June 30, 2021, Cleco Power had $4.3 million accrued for the net capital refund for capital expenditures paid for by third parties while operating under the SSR agreement. The capital refund is expected to be paid in early 2022.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Variable Interest Entities	Note 12 — 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 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 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 June 30, 2021, consisted of its equity investment of $5.6 million . During the six months ended June 30, 2021, Cleco Power had a return of equity investment from Oxbow of $3.5 million. The following table presents the components of Cleco Power’s equity investment in Oxbow: INCEPTION TO DATE (THOUSANDS) AT JUNE 30, 2021 AT DEC. 31, 2020 Purchase price $ 12,873 $ 12,873 Cash contributions 6,399 6,399 Distributions (13,700) (10,200) Total equity investment in investee $ 5,572 $ 9,072 The following table compares the carrying amount of Oxbow’s assets and liabilities with Cleco Power’s maximum exposure to loss related to its investment in Oxbow: (THOUSANDS) AT JUNE 30, 2021 AT DEC. 31, 2020 Oxbow’s net assets/liabilities $ 11,145 $ 18,145 Cleco Power’s 50% equity $ 5,572 $ 9,072 Cleco Power’s maximum exposure to loss $ 5,572 $ 9,072 The following table contains summarized financial information for Oxbow: FOR THE THREE MONTHS ENDED JUNE 30, FOR THE SIX MONTHS (THOUSANDS) 2021 2020 2021 2020 Operating revenue $ 1,627 $ 29,110 $ 3,626 $ 30,991 Operating expenses 1,627 29,110 3,626 30,991 Income before taxes $ — $ — $ — $ — Prior to June 30, 2020, DHLC mined lignite reserves at Oxbow through the Amended Lignite Mining Agreement. The lignite reserves were intended to be used to provide fuel to the Dolet Hills Power Station. Under the Amended Lignite Mining Agreement, DHLC bills Cleco Power its proportionate share of incurred lignite extraction and associated mining-related costs. Oxbow bills Cleco Power its proportionate share of incurred costs related to mineral rights and land leases. For more information on DHLC and the Oxbow mine, see Note 13 — “Litigation, Other Commitments and Contingencies, and Disclosures about Guarantees — Risks and Uncertainties.” 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 13 — 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. Cleco believes that the allegations of the petitions in each action are without merit and that it has substantial meritorious defenses to the claims set forth in each of the petitions. 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. According to the petition filed by Gulf Coast in the 12 th Judicial District Court for Avoyelles Parish, Louisiana (the “District Court”), 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 District Court denied Cleco’s exception in December 2015, after considering briefs and arguments. In January 2016, Cleco appealed the 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 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 District Court lifted the stay at the request of Gulf Coast. The parties are currently participating in discovery. Cleco believes the allegations of the petition 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, No. 263339. 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 Industries 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’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, No. 133910-A. 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 moved to stay the case, arguing that the Rapides Parish suit should proceed. On February 14, 2020, the court granted Cleco’s motion, which stay order remains in place until lifted. The 16 th Judicial District Court for the St. Mary Parish case held a hearing on October 16, 2020, and the judge granted Cleco’s declinatory exceptions of lis pendens. Thus, the St. Mary’s Parish case has been dismissed. Saulsbury filed a motion for a new trial. The hearing on this motion was held on February 5, 2021, and the 16 th Judicial District Court judge denied Saulsbury’s motion for a new trial. Saulsbury has appealed this decision. LPSC Audits 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 charges. Recovery of FAC costs is subject to periodic fuel audits by the LPSC. The LPSC FAC General Order issued in November 1997, in Docket No. U-21497 provides that an audit of FAC filings will be performed at least every other year. In March 2020, Cleco Power received a notice of audit from the LPSC for the period of January 2018 to December 2019. The total amount of fuel expense included in the audit is $565.8 million. Cleco Power has responded to several sets of data requests from the LPSC. Cleco Power has FAC filings for January 2020 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. On March 29, 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 in May 2021. On May 11, 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. Management is unable to determine the outcome or timing of the audit. For more information on these winter storms, see Note 17 — “Storm Restoration — Winter Storms Uri and Viola.” Environmental Audit In 2009, the LPSC issued Docket No. U-29380 Subdocket A, which provides Cleco Power an EAC to recover from its customers certain costs of environmental compliance. 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 March 2020, Cleco Power received notice from the LPSC of the EAC audit for the period of January 2018 to December 2019. The total amount of environmental expense included in the audit is $26.2 million. Cleco Power has responded to several sets of data requests from the LPSC. Cleco Power has EAC filings for January 2020 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 Mercury and Air Toxics Standards (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 new Administration issued an executive order, which directs federal agency heads to review regulations and other actions over the past four years to determine if they are inconsistent with the policies announced in the executive order. The order specifically directs the EPA to consider issuing a proposed rule by August 2021 to suspend, revise, or rescind the rule. The EPA determined the most environmentally protective course is to implement the rules in the executive order. 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. FERC Audit Generally, Cleco Power records wholesale transmission revenue through approved formula rates, Attachment O of the MISO tariff and certain grandfathered agreements. The calculation of the rate formulas, as well as FERC accounting and reporting requirements, are subject to periodic audits by FERC. In March 2018, the Division of Audits and Accounting, within the Office of Enforcement of FERC, initiated an audit of Cleco Power for the period of January 1, 2014, through June 30, 2019. On September 27, 2019, Cleco Power received the final audit report, which indicated 12 findings of noncompliance with a combination of FERC accounting and reporting requirements and computation of revenue requirements along with 59 recommendations associated with the audit period. Cleco Power submitted a plan for implementing the audit recommendations on October 28, 2019. Cleco Power also submitted the refund analysis on November 7, 2019, which resulted in a refund related to the FERC audit findings, pending final assessment by the FERC Division of Audits and Accounting, which is expected in the third quarter of 2021. As of June 30, 2021, the estimated refund of $4.4 million was fully refunded to Cleco Power’s wholesale transmission customers as a combination of refund payments and a reduction in Attachment O of the MISO tariff and grandfathered agreement rates over the preceding 12 months. Transmission ROE Two complaints were filed with FERC seeking to reduce the ROE component of the transmission rates that MISO transmission owners, including Cleco, may collect under the MISO tariff. The complaints sought to reduce the 12.38% ROE used in MISO’s transmission rates to a proposed 6.68%. The complaints covered the period December 2013 through May 2016. In June 2016, an administrative law judge issued an initial decision in the second rate case docket recommending a 9.70% base ROE. In September 2016, FERC issued a Final Order in response to the first complaint establishing a 10.32% ROE. However, on November 21, 2019, FERC voted to adopt a new methodology for evaluating base ROE for public utilities under the Federal Power Act. In addition, FERC set the MISO transmission owners’ region-wide base ROE at 9.88% for the refund period covered in the first complaint and going forward. The draft FERC order further found that complainants in the second complaint proceeding failed to show that the 9.88% base ROE was unjust and unreasonable and thus dismissed the second complaint. On May 21, 2020, FERC issued Opinion No. 569-A, which granted rehearing in part of Opinion No. 569, which had revised FERC’s methodology for analyzing the base ROE component of public utility rates under section 206 of the Federal Power Act. Opinion No. 569-A further refines FERC’s ROE methodology and finds that the MISO Transmission Owners’ base ROE should be set at 10.02% instead of 9.88%. Cleco Power is unable to determine when a final FERC Order will be issued. As of June 30, 2021, Cleco Power had $0.3 million accrued for the change in the ROE. In November 2014, the MISO transmission owners committee, of which Cleco is a member, filed a request with FERC for an incentive to increase the new ROE by 50 basis points for RTO participation as allowed by the MISO tariff. In January 2015, FERC granted the request. The collection of the adder was included in MISO’s transmission rates for a total ROE of 10.38% and 10.52% beginning January 1, 2020, and June 1, 2020, respectively. South Central Generating In 2017, Louisiana Generating received insurance settlement proceeds for costs incurred to resolve a lawsuit which was brought by the EPA and the Louisiana Department of Environmental Quality against Louisiana Generating related to Big Cajun II, Unit 3. Entergy Gulf States, as co-owner of Big Cajun II, Unit 3, is expected to be allocated a portion of the insurance settlement proceeds. Any amount allocated to Entergy Gulf States will be determined by ongoing litigation and negotiations. South Central Generating estimated this amount to be $10.0 million. As part of the Cleco Cajun Transaction, Cleco Cajun assumed the $10.0 million contingent liability and NRG Energy indemnified Cleco for losses associated with this litigation matter. As a result, Cleco also recorded a $10.0 million indemnification asset in Other current assets on Cleco’s Condensed Consolidated Balance Sheets as part of the Cleco Cajun Transaction. 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. As of June 30, 2021, management estimates potential losses to be $1.5 million with respect to one of these matters. Management is unable to estimate any potential losses Cleco Cajun 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 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 June 30, 2021, believes the probable and reasonably estimable liabilities based on the eventual disposition of these matters are $3.8 million and 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 and Cleco Power’s Condensed Consolidated Balance Sheets because management has determined that Cleco 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 indemnifications relate to environmental matters that may have been present prior to closing. These remaining indemnifications 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 indemnifications 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 indemnifications relate to the fundamental organizational structure of Acadia. These remaining indemnifications 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 indemnifications to Cleco Power as a result of the transfer of Coughlin to Cleco Power in March 2014. Cleco Power also provided indemnifications to Cleco Holdings and Evangeline as a result of the transfer of Coughlin to Cleco Power. The maximum amount of the potential payment to Cleco Power, Cleco Holdings, and Evangeline for their respective indemnifications is $40.0 million, except for indemnifications 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 indemnifications. 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 paid on behalf of the miner would be credited by the lignite miner against future invoices for lignite delivered. As of June 30, 2021, the maximum projected payment by Cleco Power under this guarantee is estimated to be $25.0 million; however, the Amended Lignite Mining Agreement does not contain a cap. The projection is based on the forecasted loan and lease obligations to be incurred by DHLC, primarily for purchases of equipment. Cleco Power has the right to dispute the incurrence of loan and lease obligations through the review of the mining plan before the incurrence of such loan and lease obligations. In April 2020, Cleco Power and SWEPCO mutually agreed to not 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 December 31, 2020, all lignite reserves intended to be extracted from the Oxbow mine 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. On March 19, 2021, the LPSC approved the establishment of a regulatory asset for the deferral of certain accelerated mine costs in fuel and related ratemaking treatment. Cleco Power is currently responding to data requests related to the joint filing. The Amended Lignite Mining Agreement does not affect the amount the Registrants can borrow under their credit facilities. Currently, management does not expect to be required to pay DHLC under this guarantee. Cleco Holdings, in relation to Cleco Cajun’s participation in MISO, and Cleco Power have 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. In February 2021, as a result of Winter Storms Uri and Viola, Cleco Power and Cleco Holdings, on behalf of Cleco Cajun, were required to post collateral with MISO. In March 2021, Cleco Power and Cleco Cajun settled with MISO the purchased power obligations associated with Winter Storms Uri and Viola. MISO returned associated collateral postings of $24.9 million and $6.5 million to Cleco Power and Cleco Holdings, respectively. For more information on these winter storms, see Note 17 — “Storm Restoration — Winter Storms Uri and Viola.” 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. 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. Cleco Power and Cleco Cajun are participants in the MISO market. Energy prices in the MISO market are based on LMP, which includes a component directly related to congestion on the transmission system. Pricing zones with greater transmission congestion may have higher LMPs. Physical transmission constraints present in the MISO market could increase energy costs within pricing zones. Cleco Power and Cleco Cajun use FTRs to mitigate transmission congestion price risks. Changes to anticipated transmission paths may result in an unexpected increase in energy costs. On March 1, 2019, Cleco Power began to operate the Dolet Hills Power Station from June through September of each year; however, the Dolet Hills Power Station will continue to be available to operate in other months, if needed. In June 2020, after thorough evaluation, management decided to retire the Dolet Hills Power Station. Cleco Power anticipates filing an application in the third quarter of 2021 with the LPSC giving notice that the Dolet Hills Power Station will be retired at the end of 2021. In June 2020, Cleco Power remeasured its ARO liabilities due to the expected retirement of the Dolet Hills Power Station. Cleco Power’s ARO liability increased $3.3 million as a result of this remeasurement. At June 30, 2021, Cleco Power’s undivided interest in the Dolet Hills Power Station was $62.6 million and was included in base rates. In April 2020, Cleco Power and SWEPCO mutually agreed to not 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, subject to LPSC review and approval. As of December 31, 2020, all lignite reserves intended to be extracted from the Oxbow mine 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. The expected early closure of the mines has resulted in increased costs that will be billed through the fuel adjustment clause, which management currently believes are recoverable. Management does not believe the early closure of the mines will have an adverse impact on the recovery value of the Dolet Hills Power Station. On March 19, 2021, the LPSC approved the establishment of a regulatory asset for the deferral of certain accelerated mine costs in fuel and related ratemaking treatment. Cleco Power expects to have sufficient lignite fuel available to continue seasonal operations of the Dolet Hills Power Station through the end of 2021. Cleco Power is currently responding to data requests related to the joint filing. Fuel costs incurred by the Dolet Hills Power Station are recoverable by Cleco Power through active fuel adjustment clauses. Under the Amended Lignite Mining Agreement, DHLC

Intangible Assets And Liabilities Disclosure [Abstract]
Intangible Assets and Liabilities	Note 15 — Intangible Assets and Liabilities During 2008, Cleco Katrina/Rita acquired a $177.5 million intangible asset which includes $176.0 million for the right to bill and collect storm recovery charges from customers of Cleco Power and $1.5 million of financing costs. This intangible asset was fully amortized in March 2020 and had no residual value at the end of its life. As a result of the 2016 Merger, fair value adjustments were recorded on Cleco’s Condensed Consolidated Balance Sheet for the valuation of the Cleco trade name and long-term wholesale power supply agreements. At the end of their lives, these intangible assets will have no residual value. The trade name intangible asset is being amortized over its estimated economic useful life of 20 years. The intangible assets related to the power supply agreements are amortized over the estimated life of each applicable contract ranging between 7 and 19 years, and the amortization is included in Electric operations on Cleco’s Condensed Consolidated Statements of Income. As a result of the Cleco Cajun Transaction, fair value adjustments were recorded on Cleco’s Condensed Consolidated Balance Sheet for the difference between the contract and market price of acquired long-term wholesale power agreements. At the end of their lives, these intangible assets and liabilities will have no residual value. These intangibles are amortized over the estimated life of each applicable contract ranging between 2 and 8 years. The amortization is included in Electric operations on Cleco’s Condensed Consolidated Statements of Income. As part of the Cleco Cajun Transaction, Cleco assumed an LTSA for maintenance services related to the Cottonwood Plant. This intangible liability is being amortized using the straight-line method over the estimated life of the LTSA of seven years. The amortization is included as a reduction to the LTSA prepayments on Cleco’s Condensed Consolidated Balance Sheet.

Unusual or Infrequent Items, or Both [Abstract]
Storm Restorations	Note 17 — Storm Restoration Hurricanes Laura, Delta, and Zeta In August and October 2020, Cleco Power’s distribution and transmission systems sustained substantial damage from three separate hurricanes. Cleco Power’s total storm restoration costs related to the hurricanes is approximately $243.0 million. The damage to equipment from the hurricanes required replacement, as well as repair of existing assets. Therefore, the balance sheets of Cleco and Cleco Power reflect the capitalization of approximately 63%, or approximately $152.4 million, of the total restoration costs recorded at June 30, 2021. At June 30, 2021, Cleco Power had regulatory assets for non-capital expenses related to Hurricanes Laura, Delta, and Zeta, as allowed by the LPSC, totaling $77.7 million. On December 4, 2020, Cleco Power filed an application with the LPSC requesting an interim rate recovery for return on certain storm restoration costs associated with the hurricanes until securitization of such costs can be completed. On May 19, 2021, the LPSC issued an order authorizing Cleco Power to recover $16.0 million annually for interim storm recovery costs. This order is effective until such time that the LPSC issues its order authorizing the recovery of the verified final storm costs and securitization of those costs. Cleco Power began collecting this amount through rates on June 1, 2021. On August 5, 2021, Cleco Power filed testimony with the LPSC relating to securitization of the final storm costs for Hurricanes Laura, Delta, and Zeta. Cleco Power, in line with other impacted utilities, will seek available funds from the U.S. government for relief of costs incurred from Hurricanes Laura, Delta, and Zeta. Cleco Power cannot predict the likelihood that any reimbursement from the U.S. government ultimately will be approved. Winter Storms Uri and Viola In February 2021, Winter Storms Uri and Viola reached Louisiana causing Cleco’s service territories to experience extreme and unprecedented winter weather that resulted in damage to Cleco Power’s distribution assets, electricity generation supply shortages, natural gas supply shortages, and increases in wholesale prices of natural gas in the United States, primarily due to prolonged freezing temperatures. Cleco Power’s current estimate of the total storm restoration costs related to Winter Storms Uri and Viola is approximately $10.5 million. The damage to equipment from the storms required replacement, as well as repair of the existing assets. Therefore, the balance sheets of Cleco and Cleco Power reflect the capitalization of approximately 80%, or approximately $8.4 million, of the estimated total restoration costs recorded at June 30, 2021. At June 30, 2021, Cleco Power had a regulatory asset for the remaining operations and maintenance costs of $2.0 million, as allowed by the LPSC. Cleco Power has requested recovery of these costs through the storm securitization filing that was made with the LPSC on August 5, 2021. Cleco Power’s incremental fuel and purchased power costs incurred as a result of Winter Storms Uri and Viola is approximately $55.0 million. On March 29, 2021, Cleco Power received approval from the LPSC to recover $50.0 million of these costs over a period of 12 months beginning in May 2021. On May 11, 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. Management is unable to determine the outcome or timing of the audit. Cleco Cajun's incremental negative impact of Winter Storms Uri and Viola on operations is approximately $11.2 million. The incremental impact to Cleco Cajun’s operations is subject to final settlement.

Accounting Policies [Abstract]
Covid-19 Impacts	In March 2020, WHO declared the outbreak of COVID-19 to be a global pandemic, and the U.S. declared a national emergency. In response to these declarations and the rapid spread of COVID-19, federal, state and local governments imposed varying degrees of restrictions on business and social activities to contain COVID-19, including quarantine and “stay-at-home” orders and directives in Cleco’s service territory. State and local authorities also subsequently implemented multistep policies to reopen various sectors of the economy such as retail establishments, health and personal care businesses, and restaurants, among others. During March and April 2021, due to the reduction in new COVID-19 cases and hospitalizations and the availability of COVID-19 vaccines, the governor of the state of Louisiana reduced restrictions that were previously in effect, eased capacity limits on businesses and social gatherings, and revoked the mandatory, state-wide mask mandate. However, effective August 4, 2021, the state-wide mask mandate was reinstated due to a surge in COVID-19 cases. The COVID-19 pandemic may worsen in the U.S. during the upcoming months, which may cause federal, state, and local governments to reconsider restrictions on business and social activities. In the event governments reinstate or increase restrictions, the reopening of the economy may be further curtailed. Cleco has modified some of its business operations, as these restrictions have significantly impacted many sectors of the economy. Impacts include record levels of unemployment, with businesses, nonprofit organizations, and governmental entities modifying, curtailing, or ceasing normal operations. Cleco is monitoring the ongoing COVID-19 pandemic and continues to adjust certain business practices to conform to government restrictions and best practices encouraged by the CDC, WHO, and other governmental and regulatory authorities.
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.
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. 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, 2020. These condensed consolidated financial statements, in the opinion of management, reflect all normal recurring adjustments that are necessary to fairly state the financial position and results of operations of Cleco and Cleco Power. Amounts reported in Cleco 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 estimates.
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.Prior to the repayment of the storm recovery bonds in March 2020, Cleco Katrina/Rita had the right to bill and collect storm restoration costs from Cleco Power’s customers. As cash was collected, it was restricted for payment of administrative fees, interest, and principal on the storm recovery bonds.
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. Although Cleco’s service territory experienced a recent decline in the economy in 2020 and 2021 primarily related to the COVID-19 pandemic and weather-related events, the economic outlook at June 30, 2021, was still within range of its historical credit loss analysis.
Recent Authoritative Guidance	In March 2020, FASB issued optional guidance for a limited period of time that applies to entities meeting certain criteria for the contract modifications or hedging relationships that are referencing LIBOR or another reference rate expected to be discontinued due to reference rate reform. The guidance includes a general principal that permits an entity to consider contract modifications due to reference rate reform to be an event that does not require contract remeasurement at the modification date or reassessment of a previous accounting determination. The optional guidance may be applied from March 12, 2020, through December 31, 2022. Management has identified contracts with reference rates that will be discontinued, primarily related to long-term debt obligations. In the second quarter of 2021, certain debt contracts were amended to include fallback provisions that provide substitute reference rates upon the discontinuance of LIBOR, among other amendments. Management will continue to modify contracts to include similar fallback language and expects to apply this guidance on an ongoing basis. Management does not expect this guidance to have a significant impact on the Registrants’ results of operations, financial condition, or cash flows. In December 2019, FASB amended the guidance for accounting for income taxes. The amendments simplify the accounting for income taxes by removing certain exceptions to general principles included in the accounting guidance. Effective January 1, 2021, Cleco adopted the amended accounting guidance. Adoption of this guidance did not materially impact the Registrants’ results of operations, financial condition, or cash flows.
Regulatory Assets and Liabilities	Cleco Power capitalizes or defers certain costs for recovery from customers and recognizes a liability for amounts expected to be returned to customers 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
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, 2020, and the funding relief provided by the American Rescue Plan Act, which was signed by the President on March 11, 2021, management estimates that no pension contributions will be required through 2025. As of June 30, 2021, Cleco expects to make $67.0 million in discretionary contributions to the pension plan in 2021, which would offset future required contributions. 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 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 and Cleco Power’s Condensed Consolidated Statements of Income.
