Rim Rock Wind Farm, brought online in September 2012, is located about 25 miles due north of the Glacier project. The wind farm has 126 wind turbines of 1.5 megawatts each, to be supplied by Acciona. The project had been delayed due to issues with the Montana-Alberta Tie Line, which connects wind farms in the area to Lethbridge, Alberta. Montana added two significant wind projects in 2012. The Gordon Butte Wind Farm, 9 MW, was completed early in the year and the Rim Rock Wind Project, 189 MW, was completed in September.
Montana had over 650 MW of wind generation capability at the start of 2015 and a new 240 MW project had been started in Carbon county.
