Tax equivalents expense increased $76 million for the year ended September 30, 2025, as compared to the prior year.

Additionally, tax equivalents expense increased due to an increase in the tax equivalents collected in the fuel cost recovery.

Notes

(1)  The generation for 2024 includes 99 thousand kWh of pre-commercial generation at Johnsonville Aeroderivative CT Units 21-30.  The generation for 2024 includes 137 thousand kWh of pre-commercial generation at Paradise CT Units 5-7.

(2)  Generation from TVA-owned renewable resources (non-hydroelectric) is less than one percent for all periods shown and therefore is not represented in the table above.
