2021 Transmission and Ancillary Services Rate Extension

2021 Rate Extension - rocky mountain region Transmission & Ancillary Services

Existing rates for the Rocky Mountain Region transmission and ancillary services expire September 30, 2021.  In an effort to accommodate time needed for discussion, decision making, and application of changes to these rates, WAPA plans to extend its existing transmission and ancillary services formula rates for LAP, WACM, and CRSP through September 30, 2024.  Under a  separate rate process, RMR is working on placing long-term formula rates for use under WEIS into effect for a 3-year period effective, October 1, 2021.  This will allow RMR further project planning and discussions regarding new 5-year rates for transmission, ancillary services, and losses pending the outcome of Regional Transmission Organization discussions.
