Power Rates

This page provides details and documentation on current and previous rates for BPA's power services.

 

On July 28, 2023, BPA released the Administrator's Final Record of Decision in the BP-24 Rate Proceeding, including Appendix B: 2024 Power Rate Schedules and General Rate Schedule Provisions and Appendix C: 2024 Transmission, Ancillary, and Control Area Service Rate Schedules and General Rate Schedule Provisions. BPA also released its Final Studies and Documentation on the same day. To view these documents, please refer to the BP-24 Rate Case page. 

Current Power Rates

Bonneville Power Administration's wholesale power and transmission rates for the FY 2023-2024 rate period (Oct 2023 – Sep 2025) 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 interim approval of the power and transmission rates on September 26, 2023. These rates go into effect on October 1, 2023.

During this two-year rate period, power rates may be adjusted in accordance with the Power Cost Recovery Adjustment Clause (Power CRAC), the Power Reserves Distribution Clause (Power RDC), and the Power Financial Reserves Policy (Power FRP) Surcharge (see Power GRSPs, sections II.O, II.P, and II.Q).  Any such adjustments can be viewed on the Rate Adjustments web page.

Customer TOCA Billing Determinants for FY 2023-2024 can be viewed at the BP-24 Rate Case webpage (see "BP-24 Models and Datasets" at bottom of the page).

 

Past power rate schedules are available below. A graph of Historical Priority Firm Power Rates is also available. The “Dollar Bill Graphic” shows BPA’s forecasts of its power costs and revenue sources under the BP-24 power rates. The table below shows the average power rates for the 2-year rate period. Please see the 2024 Power Rate Schedules and GRSPs for the actual rates charged.

How BPA sets Power & Transmission Rates

BPA is a self-financed federal agency. This means that BPA does not receive appropriations or tax dollars for operations and maintenance. BPA pays its expenses from revenues it receives from the sale of power and transmission services to eligible customers.
