Current Transmission Rates

BPAs wholesale power and transmission rates for the FY 2024-2025 rate period were established during the BP-24 Rate Case. The rate proceeding, conducted through a formal process described in Section 7(i) of the Northwest Power Act, concluded when the Administrator signed the Final Record of Decision on July 28, 2023. The complete rate proceeding record was then sent to the Federal Energy Regulatory Commission for their review and approval of the rates. The Commission granted final approval to the 2024 Power Rate Schedules and General Rate Schedule Provisions and the 2024 Transmission, Ancillary and Control Area Service Rate Schedules and General Rate Schedule Provisions on September 26, 2023.
