Current Power Rates
​Bonneville Power Administration's wholesale power and transmission rates for the FY 2018-2019 rate period were established during the BP-18 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 26, 2017.

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 2018 Power Rate Schedules and General Rate Schedule Provisions (revised June 21, 2018 to reflect the FY 2018 Spill Surcharge) and the 2018 Transmission, Ancillary and Control Area Service Rate Schedules and General Rate Schedule Provisions on March 19, 2018. These rates are in effect from October 1, 2017 through September 30, 2019 (FY 2018-2019).

BPA adjusts its power rates in accordance with the Power Cost Recovery Adjustment Clause (Power CRAC), the Power Reserves Distribution Clause (Power RDC), the Emergency NFB Surcharge1, and the Spill Surcharge (see Power GRSPs, sections II.O, II.P, and II.Q.3, and Appendix C). Neither the Power CRAC nor the Power RDC triggered for FY 2018 or FY 2019. The Emergency NFB Surcharge can trigger at any time during the rate period if specified conditions occur. Implementation of the Spill Surcharge resulted in power rate adjustments in FY 2018 for the period June through September 2018, with no adjustments to power rates in FY 2019. 


Information on the Spill Surcharge is posted on the Spill Surcharge webpage.
