DULUTH, MN (KDAL) - Duluth based Minnesota Power will join forces with the Minnesota National Guard to build a solar energy project at Camp Ripley, the largest military base in the state. Subject to regulatory approval, the 10 megawatt solar energy array would cover nearly 100 acres of underutilized government property at the central Minnesota camp. The solar farm and backup generation will be designed to allow Camp Ripley to use the energy produced when the electric grid is down, providing enhanced security for the military site. During non emergency operation, the solar energy produced would flow into the Minnesota Power electric service territory in central and northern Minnesota. The company hopes to complete the 25 million dollar project in late 2015 or 2016.
