Current Transmission Rates

Bonneville Power Administration's wholesale power and transmission rates for the FY 2020-2021 rate period were established during the BP-20 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 25, 2019.

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 2020 Power Rate Schedules and General Rate Schedule Provisions  and the 2020 Transmission, Ancillary and Control Area Service Rate Schedules and General Rate Schedule Provisions) on April 17, 2020. These rates went into effect on October 1, 2019.

In June, 2020, Bonneville initiated an expedited section 7(i) rate proceeding, BP-20E, to propose the suspension of the Power and Transmission Financial Reserves Policy (FRP) Surcharges for the remainder of the FY 2020-2021 rate period. On June 29, 2020, BPA released the Administrator's Final Record of Decision, June 2020, BP-20E-A-01, which adopted the suspension of the FRP Surcharge.  On July 23, 2020, the Federal Energy Regulatory Commission (FERC) issued interim approval of BPA’s rate proposal that provides for the suspension of the Financial Reserves Policy (FRP) Surcharges.  Per BPA’s request, FERC granted the approval effective July 1, 2020.  Bonneville issued revised 2020 Power Rate Schedules and General Rate Schedule Provisions (Rev. Eff. 7-1-2020) and the 2020 Transmission, Ancillary, and Control Area Service Rate Schedules and General Rate Schedule Provisions (Rev. Eff. 7 1-2020) which are in effect July 1, 2020 through September 30, 2021.
