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.
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.
