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.
BPA, in collaboration with interested parties in the region, reviewed and updated the 1984 Average System Cost (ASC) Methodology in recognition of changes in energy markets and/or policy decisions over the past 20 years. The result was the publication and implementation of the 2008 ASC Methodology in June, 2008.
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 forecast the REP costs that must be collected in rates for the rate period.
WP-07 Supplemental Power Rate Case
For the WP-07 Supplemental Power Rate Case, FY 2009 ASCs were calculated during an expedited review process. Currently, BPA and regional parties are completing a formal ASC review to verify, or amend if necessary, the FY 2009 ASCs.
WP-10 Rate Case
BPA is also in the process of completing a separate review process for ASC determinations to be used in the WP-10 Rate Case, currently in progress.
As part of the FY 2009 ASC determination process, BPA agreed to publish monthly updates (see below) of actual ASCs as determined in the expedited review process. Once the formal ASC determinations are finalized, a true-up will be completed if necessary.
