*Tri-State filed its Electric Resource Plan (ERP) with the Colorado Public Utilities Commission (PUC) on December 1, 2020. The plan is subject to review and approval by the PUC, and is subject to change as technology, markets and regulatory conditions change over the implementation period.

Case Study: Collaboration in Action

As we developed our Responsible Energy Plan (REP) commitments, we collaborated with a diverse advisory group, facilitated by Colorado State University’s Center for the New Energy Economy (CNEE) and Colorado Governor Bill Ritter, on key elements regarding emission reductions.

This group included representatives from across the states Tri-State serves from academic, agricultural, cooperative, electric industry, environmental, rural, and state and local government groups. These advisors gathered to learn with us, share with us, challenge us, and roll up their sleeves to work with us on some of the details that will make our energy transition vision a reality.
