Montana Wind Farm Locations and Capacity

Montana’s first commercial scale wind farms were installed in 2005, the same year the Montana Renewable Power Production and Rural Economic Development Act established a renewable portfolio standard for the state. Further wind development has been driven by renewable portfolio standards in other states across the west, primarily California’s mandate for 33% renewable energy by 2020.
