DENVER - The Colorado Public Utilities Commission (PUC) will conduct a public comment hearing seeking comments on the cost recovery of retiring and/or the transition of four of PSCO’s coal-fired power plants.

Meeting Details

What You Need to Know

The public comment hearing is part of Proceeding No. 22A-0515E, which evaluates the appropriate methods for PSCO to recover costs associated with the early retirements of three coal-fired power plants (Craig 2, Hayden 1 and 2) and the retiring coal portion of the Pawnee plant as it converts to natural gas. The proceeding is the result of the Commission’s Phase One Decision in Proceeding No. 21A-0141E addressing PSCO’s Electric Resource Plan (ERP) and Clean Energy Plan (CEP).

The Commission approved PSCO’s proposed early retirements, and the natural-gas conversion of one of the coal-fired power plants but declined to approve the approach for determining cost recovery. Consequently Proceeding No. 22A-0515E was opened to review the appropriate cost recovery approach. Public Service proposes to recover costs via regulatory assets but asks the Commission to defer to a future proceeding the determination of the amortization periods and return on the regulatory assets.

Parties in this proceeding consist of: PSCO, staff of the Public Utilities Commission, the Office of Utility Consumer Advocate, Climax Molybdenum Company (Climax), Colorado Energy Consumers (CEC), the Natural Resources Defense Council and Sierra Club (collectively the Conservation Coalition). An evidentiary hearing is scheduled for March 20-22, 2023, and an alternative hearing date has been reserved for April 6-7, 2023.
