The IRA created a nuclear production tax credit for electricity produced and sold beginning in 2024 and a clean fuel production tax credit for clean fuel produced and sold beginning in 2025. For the six months ended June 30, 2025, Dominion Energy’s and Virginia Power’s effective tax rate includes a $40 million income tax benefit for the nuclear production tax credit. For the same period, Dominion Energy’s effective tax rate includes a $27 million income tax benefit for the clean fuel production tax credit. For the six months ended June 30, 2024, Virginia Power recorded a $17 million tax benefit which represented a prorated portion of the estimated net realizable value of the nuclear production tax credit. The ultimate nuclear and clean fuel production tax credits realized by the Companies could vary significantly based on pending final U.S. Treasury guidance. As of June 30, 2025, Dominion Energy’s effective tax rate reflects an income tax net benefit of $18 million reflecting a $30 million remeasurement of an unrecognized tax benefit partially deferred to regulatory liabilities. A reconciliation of changes in Dominion Energy’s and Virginia Power’s unrecognized tax benefits follows for the current period:
|  | Dominion Energy |  |  | Virginia Power |

Discontinued operations Income tax expense (benefit) reflected in discontinued operations is $(3) million and $40 million for the six months ended June 30, 2025 and 2024, respectively. See Note 3 for a discussion of tax expense reflected in discontinued operations during the second quarter of 2024.
