High Plains Express Transmission Project is a 2500-mile, 500-kV transmission line, originating at Laramie Station, Wyo., and terminating at Palo Verde, Ariz. The transmission line will cost about $5 billion and is scheduled for completion in 2023. The transmission project is a proactive plan for the expansion and reinforcement of the transmission grid in the states of Wyoming, Colorado, New Mexico and Arizona. The goal is to develop a high-voltage, backbone transmission system that will enhance reliability and increase access to renewable and other diverse generation resources within regional energy resource zones. The project participants include Colorado Springs Utilities, Public Service Co. of New Mexico, Salt River Project, LS Power, Tri-State G&T, Western Area Power Administration, Xcel Energy, New Mexico Renewable Energy Transmission Authority, Wyoming Infrastructure Authority, Colorado Clean Energy Development Authority, Black Hills Corporation and NextEra Energy Resources. The project is currently on hold due to market conditions.
