Income Tax Disclosure [Abstract] |
Income Taxes | INCOME TAXES The IRA established transferability markets for tax credits including nuclear PTCs, solar PTCs and I TCs. In April 2025, agreements were executed for the sale of approximately $643 million in net tax credits under the IRA. The sale primarily includes estimated nuclear PTCs of $478 million at Duke Energy Carolinas and $69 million at Duke Energy Progress, as well as estimated solar PTCs of $58 million at Duke Energy Florida to be earned through the end of 2025. Proceeds for the sale of the nuclear PTCs are expected to be received in November 2025. On July 4, 2025, the One Big Beautiful Bill Act (OBBBA) was signed into law which, among other things, modified tax legislation affecting clean energy tax credits. While transferability was preserved for tax credits established by the IRA, including the nuclear PTC, which remains available through 2032, the legislation phases out or terminates certain tax credits sooner than previously scheduled. To remain eligible for the PTC or ITC, solar and wind facilities must be placed in service by December 31, 2027, unless construction begins by July 4, 2026. For other types of facilities, the credits continue to be available at full value if construction begins by December 31, 2033, although there are new prohibited foreign entity restrictions. The OBBBA did not change the federal corporate income tax rate and did not require the remeasurement of deferred tax assets or liabilities. While Duke Energy does not expect material current year impacts to the results of operations, financial position or cash flows for the Duke Energy Registrants as a result of the OBBBA being signed into law in the third quarter of 2025, the Company will continue to evaluate the future impact of this tax law change as additional information and guidance becomes available. EFFECTIVE TAX RATES The ETRs from continuing operations for each of the Duke Energy Registrants are included in the following table.

The decrease in the ETR for Duke Energy for the three and six months ended June 30, 2025, was primarily due to an increase in the amortization of income tax credits and lower state tax expense. The decrease in the ETR for Duke Energy Carolinas for the three and six months ended June 30, 2025, was primarily due to an increase in the amortization of income tax credits and lower state tax expense. The decrease in the ETR for Progress Energy for the three months ended June 30, 2025, was primarily due to lower state tax expense. The decrease in the ETR for Duke Energy Progress for the three and six months ended June 30, 2025, was primarily due to lower state tax expense. The decrease in the ETR for Duke Energy Ohio for the three months ending June 30, 2025, was primarily due to an increase in AFUDC equity. The decrease in the ETR for Duke Energy Indiana for the three and six months ended June 30, 2025, was primarily due to an increase in the amortization of EDIT. The increase in the ETR for Piedmont for the three months ending June 30, 2025, was primarily due to higher state tax benefits in relation to pretax losses.
