2025 Rocky Mountain Transmission and Ancillary Services Rate Extension WAPA-214
The Rocky Mountain Region (RM) is extending its formula rates for LAP transmission and LAP, WACM, and CRSP ancillary services for a 2-year period through September 30, 2026. On September 8, 2023, WAPA’s Administrator authorized staff to move forward with the recommendation to pursue final negotiations for membership and expanded participation in the Southwest Power Pool Regional Transmission Organization (SPP RTO). RM and Colorado River Storage Project Management Center (CRSP MC) membership in the SPP RTO would have significant impacts on the rate methodologies. Extending the existing rates would allow RM and CRSP MC time to evaluate rate methodologies and then conduct major rate adjustment processes to put new rates in place that would become effective upon RM and CRSP MC joining the SPP RTO (currently planned for April 1, 2026).
