StatusApproved Last reviewed 2026-08-20
Applies atNew or expanding loads above 5 MW
What the filing saysNew standard data center rate effective Oct 1, 2026, approved at the Aug 20, 2026 TVA Board meeting. A Capacity Commitment Charge (CCC) applies to new or expanding loads above 5 MW as part of each data center B, C, and D rate schedule, to recover incremental capacity costs. All-in average billing impact to data center customers is expected to be about 10%, phased in over three consecutive fiscal years. A Power Interruption Provision sets terms for a data center that wants to come online before its generation capacity is available. In-flight data centers must meet specific criteria to qualify for transitional provisions (criteria not detailed in this deck). Separately, the Board updated its policy for new power requirements above 100 MW. The CCC's exact dollar amount or formula was not found in this deck.
