• Construct a new, approximately 160-mile-long, single-circuit 345 kilovolt (kV) transmission line on double-circuit capable structures from Minnesota Power’s Cuyuna Substation near Riverton, Minnesota, to Otter Tail Power’s Maple River Substation near Fargo, North Dakota 
• Upgrade the existing Maple River Substation, located near Fargo, North Dakota, and the Cuyuna Substation, located near Riverton, Minnesota 
• Modify some existing transmission line corridors, where needed, to bring this project into service

Opportunities may exist to locate the Project parallel or within an existing high-voltage transmission line corridor. We estimate up to 30 feet of right-of-way may be shared between existing structures and the new structure depending on engineering, construction and topography (see adjacent figure).
