Notes

(1)  The generation for the three months ended December 31, 2024 includes 8 thousand kWh of pre-commercial generation at Johnsonville Aeroderivative CT Units 25-28.  The generation for the three months ended December 31, 2023 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.

(3)  Raccoon Mountain Pumped-Storage Plant net generation is allocated against each TVA-operated generation facility and purchased power type for both the three months ended December 31, 2024, and three months ended December 31, 2023.
