Reduce Emissions

Eliminating all emissions from our coal plants in CO and NM by 2030

100% reduction in CO2 emissions from coal generation in New Mexico by end of 2020.
100% reduction in CO2 emissions from coal generation in Colorado by 2030.
90% reduction in CO2 emissions across generation we own or operate in Colorado by 2030.
80% reduction in CO2 emissions associated with wholesale electricity sales in Colorado by 2030.

Progress in 2021

Since 2019, we have decreased our coal capacity by roughly 20% through the retirements of Nucla Station in Colorado and Escalante Station in New Mexico.
We filed a Revised Preferred Plan to our Colorado ERP*, identifying an 80% reduction in CO2 emissions associated with wholesale electricity sales in Colorado by 2030, relative to a 2005 baseline.

*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.
