Accounting Policies [Abstract]  
Consolidation, Policy [Policy Text Block]
Consolidation
 
The accompanying Financial Statements include the accounts of IPALCO Enterprises, Inc., AES Indiana and Mid-America Capital Resources, Inc., a non-regulated wholly-owned subsidiary of IPALCO. Furthermore, VIEs in which the Company has an ownership interest and is the primary beneficiary, thus controlling the VIE, have been consolidated. All significant intercompany amounts have been eliminated in consolidation.

IPALCO consolidates the results of AES Indiana subsidiaries that qualify as VIEs. AES Indiana is the primary beneficiary and controls the most significant activities of these VIEs. At June 30, 2025 and December 31, 2024, the assets of these VIEs were approximately $1,391.3 million and $1,169.3 million, primarily consisting of property, plant and equipment, construction work in progress and other non-current assets. At June 30, 2025 and December 31, 2024, the liabilities of these VIEs were approximately $247.8 million and $180.5 million, primarily consisting of finance leases and accounts payable.
Use Of Management Estimates
Use of Management Estimates
 
The preparation of financial statements in conformity with GAAP requires that management make certain estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements. The reported amounts of revenue and expenses during the reporting period may also be affected by the estimates and assumptions management is required to make. Actual results may differ from those estimates. Significant items subject to such estimates and assumptions include: recognition of revenue including unbilled revenue; the carrying value of property, plant and equipment; the valuation of insurance and claims liabilities; the valuation of allowances for credit losses and deferred income taxes; regulatory assets and liabilities; liabilities recorded for income tax exposures; litigation; contingencies; and assets and liabilities related to AROs and employee benefits.
