PORTLAND, Ore. – Changes to the Western Resource Adequacy Program (WRAP) Tariff, which will allow WRAP to implement proposals approved by the Western Power Pool Board of Directors on September 30, were accepted last week by the Federal Energy Regulatory Commission (FERC).
The Tariff changes stem from a FERC filing (Docket ER26-3900-000) made immediately after the Board approval. The changes approved by the Board include a proposal to establish the Rockies Subregion, which would include Public Service Company of Colorado and CORE Electric Cooperative, who officially joined the program in September. Additional Rockies participants are expected to join WRAP in 2027.
The filing also reflected approved proposals to update the Forward Showing deadline for the Rockies subregion, calculate Capacity Critical Hours by subregion, and update the methodology for contingency reserves. Tariff changes are now effective, retroactive to October 1.
WPP made a second filing on October 26 seeking FERC approval of the WRAP deficiency charge deferral mechanism also passed by the Board in September. WPP has requested a ruling and effective date of December 26, 2026, for this change.
“Through its stakeholder-led governance process, WRAP continues to evolve and improve ahead of the first binding Forward Showing in the spring,” said WRAP Director Dave Zvareck.
The Board is expected to consider additional WRAP proposals at its December meeting.
