North Plains Connector is an approximately 370-mile, up to 600 kilovolt high voltage direct current (HVDC) transmission line connecting the Eastern and Western Interconnections in Montana and North Dakota.
Grid United is developing a series of utility-scale transmission line projects to increase reliability, mitigate the impact of extreme weather events, and provide electricity consumers with access to low-cost resources. Grid United’s transmission projects are open to all sources of electric power generation.
Grid United and Black Forest Partners are co-developing the Southline Transmission Project (Southline), a 280-mile, double-circuit, high voltage transmission line and associated substation facilities. Southline will connect the electrical transmission systems of the El Paso and Tucson metropolitan areas and comprises new facilities as well as upgraded WAPA facilities.
