The Mountain West Transmission Group (Mountain West) is an informal collaboration of electricity service providers that are working to develop strategies to adapt to the changing electric industry. The group was formed in early 2013 to evaluate an array of options ranging from a common transmission tariff to regional transmission organization (RTO) membership. Based on the results of extensive evaluations, Mountain West decided to focus its attention on full membership in an existing RTO.
April 23, 2018: WAPA is assessing next steps following Public Service Company of Colorado’s decision to withdraw from the initiative.
WAPA appreciates the strong collaborative partnerships within the Mountain West Transmission Group and remains committed to
working with neighboring entities across its 15-state footprint to develop
strategies to adapt to the evolving electricity industry. WAPA will continue to
evaluate and pursue opportunities to optimize the use of generation and
transmission resources across multiple utility systems.
Sept. 22, 2017: The Mountain West participants completed initial discussions with the Southwest Power Pool’s management team, concerning membership in the SPP RTO. Through these discussions, Mountain West has determined that membership in SPP would provide opportunities to reduce customer costs, and maximize use of resources and the grid.
