The Colorado Public Utilities Commission approved Public Service Company of Colorado, a subsidiary of Xcel Energy Inc., to retire two-coal fired units in the Comanche Station, a decade ahead of schedule, as part of the company’s 2016 electric resource plan, according to the agency’s Sept. 10 decision. The commission found that the retirement of the coal units in 2022 and 2025 is in the public interest, allowing Xcel to take advantage of the “exceptionally low bid prices” from its competitive solicitation in the resource planning process. The plan includes the acquisition of over 1.1 gigawatts of new wind generating capacity, and the procurement of over 700-megawatt of new solar and 275-megawatt of battery storage. The utility expects the plan to result in more than $200 million savings to ratepayers.
