For several years, south central Colorado has witnessed tremendous growth in residential population, business, industry and agriculture.
In addition, the abundant amount of sunshine has placed this part of the state on the nationwide map for being ripe with potential of renewable wind and solar development.
As a result of this growth, electric utilities in the region have identified critical transmission infrastructure improvements needed to deliver reliable electric power, relieve capacity constraints and offer increased economic development opportunities through renewable energy investment.
Tri-State Generation and Transmission Association and Public Service Company of Colorado (PSCo), an Xcel Energy Company, have partnered to address these concerns by jointly pursuing a single transmission project (known as the San Luis Valley - Calumet - Comanche Transmission Project) to alleviate reliability challenges and helps further Colorado's New Energy Economy through renewable energy development.
"It's important to applaud the state's largest two electric utilities for jointly developing this project. The partnership provides cost savings and environmental benefits through joint planning, construction and operation of the project."
– U.S. Congressman John Salazar

There is great concern regarding the reliability of existing electricity service if additional transmission lines are not constructed to meet these needs. In response, both Tri-State and Xcel Energy have identified this project to strengthen the state's power delivery infrastructure, serve growing electricity needs and harness the power of the sun and wind to develop renewable energy.
In addition, this project is needed to meet renewable energy state mandates including Colorado Senate Bill 07-100 that sets forth guidelines to build transmission projects that accommodate the development of renewable generation and Colorado's renewable portfolio standards.
"The new transmission line is long overdue and without the increased capacity, the San Luis Valley will not have the adequate infrastructure available to attract new businesses and industries that would help improve the quality of life for our region."
