Our Projects

North Plains Connector

North Plains Connector is a 420-mile, up-to-525-kilovolt, high-voltage direct current transmission line connecting the eastern and western U.S. electric grids in North Dakota and Montana.

Pecos West

Pecos West is a high-voltage direct current (HVDC) transmission line that will link the rapidly growing metro areas of El Paso, Texas, with southeastern New Mexico. Pecos West creates a vital connection between the Western and Eastern Interconnections of the U.S. electric grid. 

Southline Transmission Project

Grid United and Black Forest Partners are co-developing Southline Transmission Project (“Southline”), an approximately 280-mile, double-circuit, high-voltage transmission line and associated substation facilities.

Three Corners Connector

Three Corners Connector is a 300-mile, up-to-525 kilovolt HVDC transmission line connecting the existing electric systems near Pueblo, Colorado, and the Oklahoma Panhandle, providing a valuable link between the Eastern and Western Interconnections. 

Wyoming Intertie

Wyoming Intertie is an approximately 106-mile, up-to-1,800 MW, high-voltage transmission line connecting the Eastern and Western Interconnection grids. The line extends through Carbon, Albany, and Platte Counties in Wyoming, with endpoints in Carbon County and Platte County.
