Online since 2016, Xcel Energy’s (“Xcel”) 120MW Comanche Solar project is the largest solar project east of the Rockies (~3.5 megaton carbon offset), generating enough energy to power more than 31,000 homes. Under EPC contract with Xcel, CG Power USA Inc. (“CGP”) subcontracted Irby in December 2015 to construct a 34.5/230kV substation for the project including a 2.5 mile 34.5kV interconnection between the east and west solar fields and a 230kV underground transmission line from the substation to Xcel’s Comanche Generation Station. The Irby work scope was completed in under six months with zero lost time incidents.
Start Date: December 2015
Completion Date: May 2016
