Check out the MariBell News Page, a library of expert perspectives on how the MariBell Transmission Project will benefit the communities Dairyland serves. It's a quick one-click stop to letters to the editor, blogs, guest columns and op-eds that have been submitted in support of MariBell.
The proposed MariBell project is an approximately 140-mile, 765 kilovolt (kV)/161 kV double circuit transmission line being developed by Dairyland and GridLiance Heartland. It is proposed to extend from Marion, Minn., to Bell Center, Wis., crossing through Olmsted, Mower, Fillmore and Houston counties in Minnesota, and Vernon and Crawford counties in Wisconsin.
The project is part of a larger effort by the Midcontinent Independent System Operator (MISO), the regional transmission organization covering 15 states and the Canadian province of Manitoba, to maintain a resilient and flexible electric grid. The MariBell segment was directly assigned to Dairyland by MISO.
