Voltage: 230 kV line
Estimated length: 20 miles
Estimated cost: $41 million
Growth in and around the City of Minot has resulted in the need for additional electric power. To continue to meet those needs, the North Dakota Public Service Commission approved our plan to upgrade the electric transmission system by constructing a 230 kilovolt (kV) Magic City-McHenry transmission line and substation southeast of Minot. The approximately 20-mile transmission line runs between the existing McHenry Substation near Velva and the new Magic City Substation located near the Minot waste water treatment facility (view map below).
The majority of the transmission line route follows an existing 115 kV transmission line. We replaced the existing 115 kV transmission line and structures with new single pole steel structures that carry both the new 230 kV transmission line and the existing 115 kV line. In North Prairie Township, the route deviates from the existing 115 kV transmission line for approximately 4.2 miles and will be located in new right-of-way. In addition, approximately 1.2 miles of new 115 kV transmission line was constructed along a new right-of-way to connect the new Magic City Substation to our existing electrical grid in the City of Minot. The 115 kV line was energized in September and the 230 kV line was energized in November 2018.
The project will provide increased reliability of electric service in the Minot area by adding another source of electricity.
We filed an application for a Certificate of Corridor Compatibility and Transmission Facility Route Permit with the North Dakota Public Service Commission (ND PSC) in March, 2017. The Commission approved the Route Permit and Certificate of Corridor Compatibility on October 4, 2017. You can view the filing on the ND PSC website (external website) by searching case number PU-17-102. A Certificate of Convenience and Necessity (CCN) was issued by the ND PSC on January 4, 2017. You can view the regulatory filings on the ND PSC website (external website) by searching case number PU-16-644.
