Wind power in Montana

[1] At a nameplate capacity of 210 megawatts (MW),[2][3] the $500 million[4][5] Glacier Wind Farm, which is located in Toole and Glacier counties,[2] became Montana's largest in October 2009,[4] surpassing the 135 MW Judith Gap Wind Farm in Wheatland County.

[4] Rim Rock Wind Farm, brought online in September 2012, is located about 25 miles due north of the Glacier project.

[6] The project had been delayed due to issues with the Montana-Alberta Tie Line, which connects wind farms in the area to Lethbridge, Alberta.

Glacier Wind Farm became Montana's largest wind farm with completion of the first 106.5 MW stage in late 2008, then nearly doubled in size to a 210 MW capacity when joined by the second stage in 2009.

Glacier was surpassed by the 240 MW Pryor Mountain Wind Project upon its completion in late 2020.
