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. EFFECTIVE TAX RATES The ETRs from continuing operations for each of the Duke Energy Registrants are included in the following table.
