Bemidji-Grand Rapids 230 kV project

The Bemidji-Grand Rapids transmission line was energized in 2012 to improve reliability for the Red River Valley, Bemidji, Grand Rapids and north central Minnesota. Read press release

The single circuit 230 kilovolt (kV) transmission line connects the Wilton Substation near Bemidji, Minnesota and the Boswell Substation in Grand Rapids, Minnesota.

Construction began in January of 2011 and the line was fully energized in September of 2012.  The project includes steel H-frame structures between 70 and 90 feet tall, and steel single-pole structures between 95 and 115 feet tall.

Minnesota permitting

The Minnesota Public Utilities Commission must grant two approvals before construction – a Certificate of Need and a Route Permit. An environmental report is prepared by the Department of Commerce, Office of Energy Security during the need process, and an Environmental Impact Statement (EIS) is written during routing.
