About

The proposed NWMT-310 project is a 450 MW battery storage development in Meagher County, Montana. Interconnection is with NorthWestern Energy (NWMT) in the West region. The project entered the interconnection queue on December 21, 2016, with a proposed commercial operation date of February 1, 2023. Its interconnection status is currently in the Facility Study phase.

The project consists of 450 MW of "Other Storage" technology. The point of interconnection is at a new 500kV substation between Broadview and Townsend. The project's status is currently listed as suspended.
