Residential Exchange Program

Under the REP, BPA "purchases" power from each participating utility at that utility's Average System Cost (ASC). The Administrator then offers, in exchange, to "sell" an equivalent amount of electric power to the utility at BPA's PF Exchange rate. The amount of power purchased and sold equals the qualifying residential and farm load of each utility participating in the REP. This qualifying residential and farm load (residential load) is then multiplied by the difference between BPA's PF Exchange rate and the utility's ASC to derive the utility's REP benefits. These benefits are passed on to the residential and farm customers of the utility. To calculate an ASC, BPA reviews the participating utility’s resource costs and loads as directed in the 2008 ASC Methodology (18 CFR Part 301, Sales of Electric Power to BPA; Revisions to Average System Cost Methodology). Under the 2008 ASCM, a utility's ASC is generally determined by dividing the utility's allowed cost of resources (Contract System Cost) by the utility's total system load (Contract System Load). The resulting quotient of this calculation is the utility's ASC. BPA determines ASCs in ASC Review Processes which take place concurrently with BPA's rate proceeding. Utilities participating in the REP must submit ASC filings and all associated documentation in the ASC Review Processes in accordance with the filing procedures set forth in the 2008 ASCM and the Rules of Procedure for BPA’s ASC Review Process (Rules of Procedure).

At the conclusion of the ASC Review Processes, BPA issues Final ASC Reports for each of the REP‑participating utilities which establish the utilities’ ASCs for the upcoming Exchange Period. ASCs are also a component used by BPA in the rate proceeding to determine the respective utilities’ REP benefits.

The 2012 REP Settlement (REP-12 Proceeding)

BPA conducted the REP-12 proceeding to review the terms and conditions of a long-term settlement of issues regarding the implementation of the Residential Exchange Program (2012 REP Settlement). This proceeding concluded with the Administrator's issuance of a Final Record of Decision (ROD) on July 26, 2011 which reflected his decision to adopt the 2012 REP Settlement.

One party challenged BPA in the United States Court of Appeals for the Ninth Circuit (Court) on the 2012 REP Settlement. On May 22, 2015, the Court issued a memorandum opinion in Public Power Council v. U.S. Dept. of Energy, 2015 WL 2448336, which dismissed as moot the Western Public Agency Group’s (WPAG) challenge to BPA’s WP-07S ROD. This dismissal effectively ended all current challenges related to the REP.

ASCs for the FY 2022-2023 Exchange Period were determined in the FY 2022-2023 ASC Review Processes. The PF Exchange Rates for REP-participating utilities eligible for REP benefits during the FY 2022-2023 Exchange Period are listed below. The PF Exchange Rates are comprised of a base PF Exchange Rate plus a utility-specific 7(b)(3) supplemental rate charge. For additional information see the BP-22 Power Rate Schedules and General Rate Schedule Provisions and BP-22 Rate Case. The ASCs and the PF Exchange Rates, below, were uploaded to this website on October 1, 2021. These ASCs will become effective for the FY 2022-2023 Exchange Period on October 1, 2021, and remain in effect through September 30, 2023.

REP Compliance Review Program

Section 5 of the NW Power Act requires BPA to ensure payments made to REP-participating utilities are passed on to the utilities' retail residential and farm customers (residential loads). By law, these REP payments must be “passed through directly” to the utility’s residential loads and appear as a credit on the utility customers’ monthly bills. To ensure these payments are distributed to eligible retail customers correctly and in a timely manner, BPA developed the REP Compliance Review Program. Through the REP Compliance Review Program, BPA reviews the REP benefits received by the utilities from BPA and passed through to their qualifying REP customers.

REP Customer Load Eligibility Guidelines (CLEG)

BPA developed the Customer Load Eligibility Guidelines (CLEG) to provide guidance to REP-participating utilities in determining eligibility of residential, farm, and irrigation/pumping loads for REP benefits under the NW Power Act. Specifically, the CLEG addresses a variety of issues related to eligible and ineligible retail customers under the REP. The CLEG is intended to be used as a guideline only and may be revised or cancelled by BPA at any time. Throughout the term of the REP, BPA has made periodic updates to the CLEG. BPA, REP-participating utilities, and other interested parties worked together to update and provide greater clarity to the CLEG.
