The High Plains Express Transmission Project

The High Plains Express Transmission Project (HPX) 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 first phase of the HPX is a joint participation feasibility study that will explore transmission alternatives. Eight parties, including Xcel Energy, have initiated a feasibility study, which they hope to complete by August 2007.
