The Aeolus Project involves building a 140-mile, 500-kV transmission line from a new Aeolus substation to a new Anticline substation; 230-kV transmission line from the Shirley Basin substation to the Aeolus substation; rebuilding four miles of existing 230-kV transmission line between the Aeolus and Freezeout substations; and rebuilding 14 miles of a 230-kV transmission line between the Freezeout and Standpipe substation. The project is part of the greater Gateway West Transmission Project. According to THUB calculations, the project has an estimated cost of $300m.
