Income Tax Disclosure [Abstract] |
Income Taxes | INCOME TAXES On August 16, 2022, the IRA was signed into law. Among other provisions, the IRA created a new, zero-emission nuclear power PTC available for taxpayers beginning January 1, 2024. In the first quarter of 2024, Duke Energy Carolinas and Duke Energy Progress recorded a PTC deferred tax asset of approximately $107 million and $14 million, respectively. These amounts represent the net realizable value of the PTCs, which were deferred to a regulatory liability. The Subsidiary Registrants will work with the state utility commissions on the best regulatory process to pass the net realizable value back to customers over time. See Note 4 for additional information on Duke Energy Carolinas' approval for a stand-alone rider starting January 1, 2025. The Company will continue to assess its calculations and interpretations as new 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.
