Overview of Mountain West
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.
Mountain West includes two investor-owned utilities; two municipal electricity providers; two generation and transmission cooperatives; and two federal power marketing administration projects. The Mountain West participants are a subset of the WestConnect planning region and are members of the Colorado Coordinated Planning Group (CCPG). Current participants are listed below and other electricity providers may join after initial implementation.
- Basin Electric Power Cooperative (BEPC)
- Black Hills Corporation’s three electric subsidiaries:
- Black Hills Power (BHP)
- Black Hills Colorado Electric Utility Company (BHCE)
- Cheyenne Light Fuel & Power Company (Cheyenne)
- Colorado Springs Utilities (CSU)
- Platte River Power Authority (PRPA)
- Public Service Company of Colorado (PSCo)
- Tri‐State Generation and Transmission Association (Tri‐State)
- Western Area Power Administration (WAPA)
- Loveland Area Projects (LAP)
- Colorado River Storage Project (CRSP)
The Mountain West participants have executed a non-binding letter of understanding to hold detailed discussions with SPP about how the RTO might accommodate the terms of the Mountain West MOU and other related rate design specifications. This is not a decision to join SPP. This step is focused on having further and more in-depth discussions with SPP to determine whether the needs of Mountain West can be met. In the event these discussions are unsuccessful, the Mountain West participants may pursue similar discussions with MISO, PJM, or both.
