Beginning of the End for Colstrip? Washington UTC Rejects Puget Sound Energy's Analysis of Coal Plant Economics
The Washington Utilities & Transportation Commission ("UTC") yesterday rejected Puget Sound Energy's ("PSE") economic justification for continued operation of its Colstrip coal plant. The UTC's action, while not sealing the fate of Colstrip, sends PSE back to the drawing board and casts doubt on the future of the plant, which is already the subject of legal action brought by a coalition of environmental groups.
The UTC's findings were made in the context of PSE's 2013 Integrated Resource Plan. Under Washington law, the state's investor-owned utilities are required to develop and submit an Integrated Resource Plan to the UTC, which must be updated every two years. The Integrated Resource Plan is intended to analyze the alternatives available to meet the utility's anticipated load, and to identify the least-cost alternatives.
