Tri-State and PSCo are jointly pursuing transmission projects in southern Colorado in order to strengthen the region's power delivery infrastructure, serve growing electricity needs and provide for the interconnection of new energy resources.

Through participation in the Colorado Coordinated Planning Group, Tri-State and PSCo continue their collaboration to develop this long-term solution to the state's transmission challenges. Both have transmission resources, shared assets and load-serving responsibilities throughout Colorado, and are looking to support Colorado state energy policy, economic development and growth.

Public Service Company of Colorado (PSCo) is an Xcel Energy company. Xcel Energy is a major U.S. electricity and natural gas company with regulated operations in eight Western and Midwestern states. Xcel Energy provides a comprehensive portfolio of energy-related products and services to 3.4 million electricity customers and 1.9 million natural gas customers

Tri-State Generation and Transmission Assn., Inc, a non-profit electric utility, is a wholesale electric power supplier owned by the 44 electric cooperatives that it serves. Tri-State generates and transports electricity to its member systems throughout a 250,000 square-mile service territory across Colorado, Nebraska, New Mexico and Wyoming.
