Residential Exchange Program (REP)

​As part of the Pacific Northwest Electric Power Planning and Conservation Act (Northwest Power Act), the Residential Exchange Program (REP) was created to provide residential and small farm customers of Pacific Northwest (regional) utilities a form of access to low-cost Federal power. 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 is the qualifying residential and small farm load of each utility participating in the REP. These benefits are passed on to the residential and small 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 the Bonneville Power Administration; 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. These ASCs are determined in an ASC Review Process administered by BPA in the year prior to the commencement of BPA's wholesale power 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.

Utility ASCs are not determined in BPA rate proceedings. Instead, ASCs are determined in a separate administrative process that BPA conducts pursuant to the procedural rules of the 2008 ASC Methodology. Utility ASCs, once established in the ASC Review Process, are one component used by BPA in the rate proceeding to determine individual utility REP benefits.

Once ASCs for all participating utilities are determined for the corresponding Exchange Period, ASC Final Reports will be published at this website.

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 October 28, 2013, the Court issued its decision in the case of Assoc. of Pub. Agency Customer v. Bonneville Power Admin., Case No. 11‑73178 (APAC) in which the Court affirmed BPA’s decision to adopt the 2012 REP Settlement.  The mandate in APAC was issued on December 23, 2013.   
BP-14 Rate Case

ASCs for the FY 2014-2015 Exchange Period were determined in the FY 2014-2015 Review Processes. The PF Exchange Rates for REP-participating utilities are listed below. The PF Exchange Rate is comprised of a base PF Exchange Rate of $46.32/MWh plus a utility-specific 7(b)(3) supplemental rate charge. For additional information see the BP-14 Power Rate Schedules and General Rate Schedule Provisions and BPA's 2014 Rate Proceeding (BP-14 rate case). The ASCs and the PF Exchange Rates, below, were updated on October 28, 2014.

REP Compliance Review Program

Section 5 of the NW Power Act requires the Bonneville Power Administration (BPA) to make certain payments to eligible utilities to reduce the wholesale costs of producing and transmitting power to the utility’s residential and farm loads.  By law, the payments BPA makes to eligible utilities under the REP must be passed through to the utility’s retail residential and farm customers.  These REP payments 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 monitors the utilities’ systems, procedures, and internal controls surrounding the invoicing of monthly REP loads and payments.
REP Customer Load Eligibility Guidelines (CLEG)

BPA developed the Customer Load Eligibility Guidelines (CLEG) to provide guidance to REP- participating utilities in determining whether residential, farm, and irrigation/pumping loads are eligible for REP benefits under the NW Power Act.  Specifically, the CLEG provides guidance to utilities regarding a variety of issues related to eligible and ineligible retail customers under the REP.  The CLEG is intended to be used as guidelines 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.  Most recently, BPA, utilities participating in the REP, and other interested parties worked together to update and provide greater clarity to the CLEG.
