, there was an increase due to depreciation of additions to net completed plant.  

Tax equivalents expense increased $55 million for the nine months ended June 30, 2025, as compared to the same period of the prior year.  This change is primarily driven by an increase in TVA's revenue from sales of electricity in 2024, which is used as the basis for calculating tax equivalent expense.

Notes

(1)  The generation for the three months ended June 30, 2025 includes 35 thousand kWh of pre-commercial generation at Johnsonville Aeroderivative CT Units 21-30.  The generation for the three months ended June 30, 2024 includes no 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.
