About the Study
The Montana Regional Transmission Connectivity Study is a transmission planning study aimed at exploring upgrades that will increase regional access to Montana generation resources and enhance Montana interties to neighboring states. The study evaluated a series of resource deployment scenarios that reflect feasible ranges of generation resource expansion in Montana.
Power system modeling was used to assess transmission needs under these scenarios and identify strategic transmission expansion solutions that are coordinated and phased. These solutions include greenfield lines, reconductoring, high-capacity conductors, and high voltage direct current (HVDC) transmission lines and create synergies with existing and planned transmission facilities across the West.
