Great Northern Transmission Line

MISO ↔ Manitoba Hydro · AC transmission

The 500 kV international line energized in June 2020 between Manitoba Hydro's system and Minnesota Power's Iron Range substation. Its map marker is at DOE's published border crossing; the MISO–Manitoba market interface is an aggregate of multiple physical ties, not a dedicated Great Northern meter.

Sources and method

No operator flow feed is linked to this profile. The map and hardware describe the registered connection, not a current power transfer. A rating describes the equipment; an operator’s posted directional limit, when available, is a separate operating value. The map point identifies a sourced terminal or crossing where available, or a representative connection point; it does not trace the full route.
