USA, St. Cloud: Minnesota Power and Great River Energy continue with their joint 345 kV transmission line project.
Minnesota Power and Great River Energy have applied for a certificate and permit from the Minnesota Public Utilities Commission (MPUC) to build the Northland Reliability Project.
The project involves a 290 km (180 mile), double-circuit, 345 kV transmission line from northern Minnesota to central Minnesota, which will strengthen the region’s electric reliability. The project is worth between $970 M and $1.3 B. It is estimated that the construction will start in 2027 and that it will become operational in 2030.
The first segment of the project involves the construction of about 225 km (140 miles) of 345 kV double-circuit transmission lines from Minnesota Power’s Iron Range Substation to Great River Energy’s Benton County Substation.
The second segment will comprise of a 32 km (20 mile) 230 kV line to be replaced with two 345 kV circuits along the Benton County Substation to a Big Oaks Substation. A 32 km (20 mile) 345 kV line will also be replaced along the Benton County Substation to the Sherco Substation.
The Northland Reliability Project will expand the Iron Range Substation near Grand Rapids and the Benton County Substation near St. Cloud. Also, Cuyuna Series Compensation Station will be built near the existing Riverton Substation.
