 Aeroderivative CT Units 21-30 in 2025 and Paradise CT Units 5-7 in 2024. 

    TVA's two largest LPCs — Memphis Light, Gas and Water Division ("MLGW") and Nashville Electric Service ("NES") — have contracts with a five-year and a 20-year termination notice period, respectively.  Sales to MLGW and NES accounted for nine percent and eight percent, respectively, of TVA's total operating revenues during both the years ended September 30, 2025 and 2024.

TVA's rate structure uses pricing signals to indicate seasons and hours of higher cost to serve its customers and to capture a portion of TVA's fixed costs in fixed charges.  The structure includes three base revenue components: time of use demand charges, time of use energy charges, and a grid access charge ("GAC").  The demand charges are based upon the customer's peak monthly usage.  The energy charges are based on time differentiated kWh used by the customer.  Both of these components can be significantly impacted by weather.  The GAC captures a portion of fixed costs and is offset by a corresponding reduction to the energy rates.  The GAC also reduces the impact of weather variability to the overall rate structure.

    TVA has a Partnership Agreement option that better aligns the length of LPC power contracts with TVA's long-term commitments.  Under the partnership arrangement, the LPC power contracts automatically renew each year and have a 20-year termination notice.   The partnership arrangements can be terminated under certain circumstances, including TVA’s failure to limit rate increases to no more than 10 percent during any consecutive five-fiscal-year period, as more specifically described in the agreements.  Participating LPCs receive benefits including a 3.1 percent wholesale bill credit in exchange for their long-term commitment, which enables TVA to recover its long-term financial commitments over a commensurate period.  As of September 30, 2025, 148 LPCs had signed the 20-year Partnership Agreement with TVA.

    In addition to base revenues, the rate structure includes a separate fuel rate that includes the costs of natural gas, fuel oil, purchased power, coal, emission allowances, nuclear fuel, and other fuel-related commodities; realized gains and losses on derivatives purchased to hedge the costs of such commodities; and payments to states and counties in lieu of taxes ("tax equivalents") associated with the fuel cost adjustments.
