Xcel Energy plans to spend around $4.6 million to repair Comanche 3, Colorado’s newest and largest coal plant, which has been offline since suffering a catastrophic outage in August 2025.

The state’s largest utility has been warning regulators for months that the plant’s outage will strain electricity supply in the summer, when demand for power skyrockets. 

But despite the plant’s importance to the state’s grid, Xcel previously redacted even basic information about its repairs in documents submitted to the Colorado Public Utilities Commission (PUC). Those included information about the costs, what was broken, and emissions at its sister plant in Pueblo, Comanche 2.
