Great River Energy on June 1 submitted a status report to the Minnesota Public Utilities Commission on the Straight River Switch to Blueberry Substation and Blueberry Substation to Red Eye Substation segments of the Menahga Area 115-kV Project.
As noted in the report, the commission in March 2016 issued an order granting Great River Energy and Minnesota Power a route permit for the project.
According to Great River Energy’s website, as part of the project, the company is building about 22.5 miles of new overhead transmission line in southern Hubbard County and northern Wadena County to ensure the reliability of electric service to the members of Todd-Wadena Electric Cooperative.
Minnesota Power on Sept. 30, 2016, told the commission that all construction activities for the company’s portion of the Menahga High Voltage Transmission Line (HVTL) Project are complete. Minnesota Power said that its portion of the project includes a 0.2-mile segment of new 115-kV HVTL and an electrical substation.
Great River Energy said in its June 1 status report that construction of the Straight River Switch to Blueberry Substation to Red Eye Substation segments was completed in March, and that energization of those segments at 115 kV occurred on May 1, with minimal load, and will have full load early this month.
The Red Eye substation will be fed temporarily from the Hubbard substation source until the Blueberry substation is complete and the transmission line can be connected as designed and permitted, Great River Energy said.
The Blueberry substation site was graded last October and the foundation contractor finished as much site work as it could at the end of last November. Work on the substation has resumed and will continue through this summer, Great River Energy added, noting that the transmission line will be cut in to the Blueberry substation in the fall – scheduled for October – and the temporary line will then be removed.
