Commitments and Contingencies Disclosure [Abstract]
Commitments And Contingencies	COMMITMENTS AND CONTINGENCIES Contingencies Subsidiary Guarantees In connection with AES Indiana's renewable projects financed with a tax equity structure, AES Indiana has expressly undertaken limited obligations and commitments on behalf of certain of the Company's subsidiaries, which will only be effective upon the occurrence of future events, such as IRS recapture of tax credits, which is not expected to occur, and will be terminated upon the occurrence of future events. As of June 30, 2025, the maximum undiscounted potential exposure to tax equity financing related guarantees was $314.6 million. Legal Matters IPALCO and AES Indiana are involved in litigation arising in the normal course of business. We accrue for litigation and claims when it is probable that a liability has been incurred and the amount of loss can be reasonably estimated. While the ultimate outcome of outstanding litigation cannot be predicted with certainty, management believes that final outcomes will not have a material adverse effect on IPALCO’s results of operations, financial condition and cash flows. Accruals for legal loss contingencies were not material as of June 30, 2025 and December 31, 2024, respectively. Environmental Matters We are subject to various federal, state, regional and local environmental protection and health and safety laws and regulations governing, among other things, the generation, storage, handling, use, disposal and transportation of regulated materials, including CCR; the use and discharge of water used in generation boilers and for cooling purposes; the emission and discharge of hazardous and other materials, including GHGs, into the environment; climate change; and the health and safety of our employees. These laws and regulations often require a lengthy and complex process of obtaining and renewing permits and other governmental authorizations from federal, state and local agencies. Violation of these laws, regulations or permits can result in substantial fines, other sanctions, permit revocation and/or facility shutdowns. We cannot assure that we have been or will be at all times in full compliance with such laws, regulations and permits. Accruals for environmental contingencies were not material as of June 30, 2025 and December 31, 2024, respectively. On March 23, 2021, the U.S. District Court for the Southern District of Indiana approved and entered a judicial consent decree among AES Indiana, the United States on behalf of the EPA, and the IDEM. The decree resolved allegations by EPA and IDEM that AES Indiana had violated the federal CAA at its Petersburg Station, which AES denies. Under the decree, AES Indiana agreed to certain emission limits and annual caps on NOx, SO2 and PM emissions at the four Units at the station; paid a civil penalty of $1.525 million; retired Units 1 and 2, spent $0.325 million on an environmentally beneficial project to preserve local, ecologically-significant lands (notice of completion of which was provided May 8, 2025); and will spend a total of $5 million on a further environmental mitigation project to build and operate a new, non-emitting source of generation at the site.
