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 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).
 

If necessary, 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. The Emergency NFB Surcharge can trigger at any time during the rate period if specified conditions occur. For each year of the rate period, notice of a preliminary Spill Surcharge will be made no later than May 31.

Spill Surcharge - FY 2018

Information on the preliminary Spill Surcharge for FY 2018 will be posted on the Spill Surcharge - FY 2018 webpage.
