There is significant untapped potential for renewable energy in New Mexico and throughout the rest of the Southwestern United States, including from ready-to-deploy wind and solar projects that offer tremendous value in the form of economic, environmental, and resilience benefits. The Clean Coalition assessed the TSGT Generation, Sales, and Production Summaries in order to better understand the current situation at a major utility that is well positioned to facilitate substantial deployments of additional renewables across the Southwest.

Tri-State is a nonprofit cooperative power supplier with the mission to provide its member systems a reliable, affordable and responsible supply of electricity in accordance with cooperative principles. The cooperative is made up of 46 members, including 43 electric distribution cooperatives and public power districts in four states that together provide power to more than a million electricity consumers across nearly 200,000 square miles of the western United States.
The monthly survey Form EIA-860M, “Monthly Update to Annual Electric Generator Report,” supplements the annual survey form EIA-860 data with monthly information that monitors the current status of existing and proposed generating units at electric power plants with 1 megawatt (MW) or greater of combined nameplate capacity.
The EIA estimates the current and near-term unit inventory of electric power generating capacity by integrating the information on these surveys along with ongoing EIA research of new units. However, creating this monthly estimate sometimes requires the use of data submitted on the annual EIA-860 before it has been fully verified by EIA. For this reason, reported capacities are EIA’s preliminary estimates of capacity for that month. Estimates will be corrected without specific acknowledgement or explanation in the subsequent month’s inventory.
