Tri-State to close all coal operations in Colorado and New Mexico
Tri-State Generation and Transmission Association announced that it will shutter all of its coal operations in an effort to transition to renewables.
The Westminster-based Tri-State’s coal-powered facilities — a New Mexico coal-fired power plant and a Colorado coal plant and mine on the west slope along the Yampa Valley — will shutter all operations by the end of 2020 and 2030, respectively.
