Mountain West Transmission Group Initiative**

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.​

Current Status​​

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. Read more in the Sept. 22, 2017 news release.

Each Mountain West participant is pursuing regulatory or governing body ​approval, as applicable. ​P​​ublic proce​sses in progress include:
