The Mountain West Transmission Group (Mountain West) was an informal collaboration of electricity service providers formed in early 2013 to evaluate an array of options ranging from a common transmission tariff to regional transmission organization memberships.
Oct. 30, 2018: WAPA has decided to defer further Mountain West activity while continuing to evaluate
opportunities to optimize the use of generation and transmission resources. We appreciate
the strong collaborative partnerships with our customers and within Mountain West and remain committed to working with neighboring entities across our 15-state footprint to
develop strategies to adapt to the evolving electric industry.
Oct. 3, 2018: Black Hills Energy provided formal notice to the Colorado Public Utilities Commission that the company would not pursue membership in Southwest Power Pool at this time.
April 23, 2018: WAPA is assessing next steps following Public Service Company of Colorado’s decision to withdraw from the initiative.
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.
