 Great River Energy’s transmission system is part of an overall regional transmission grid, operated on a coordinated basis in accordance with the Minnesota Electric Transmission Planning group.Regional grid operations were expanded in 2002 with the formation of the MISO, an independent, nonprofit organization that supports the reliable operation of the transmission system in 15 U.S. states and the Canadian province of Manitoba.MISO acts as the Regional Transmission Organization, overseeing the operations, planning, and improvements of the wholesale bulk electric transmission system in the upper Midwest.
