Xcel Submits Plans to Commission for Emission Reductions from Coal Plants
LCG, August 19, 2010--Xcel Energy submitted to the Colorado Public Utility Commission its plan to comply with the state's the Clean Air, Clean Jobs Act, which requires Xcel to reduce nitrogen oxide emissions by 70 to 80 percent from several coal-fired power plants by December 31, 2017.
Xcel's proposed plan will retire 900 MW of coal-fired generation at the Valmont and Cherokee stations by the end of 2017 and 2022, respectively. Furthermore, the 717-MW Cherokee facility will be repowered to use natural gas, which will increase the capacity to 883 MW. Unit 4 of the Arapahoe plant will also be repowered. To further reduce emissions, new emission controls will be installed at the Pawnee and Hayden power plants.
Overall, Xcel stated that construction costs will be $1.3 billion over the next 12 years.
The legislation and proposed plan are opposed by some local communities where coal is mined in northwest Colorado. The Moffat County Commission on Tuesday approved the signing of resolution No. 2010-80 in support of the Associated Governments of Northwest Colorado?s (AGNC) response to the petition?s denial by the Air Quality Control Commission of a prior request to allow public input on the emission reduction plans required by the bill. By signing the resolution, the commission will support and participate in an AGNC request for a judicial review of the petition?s denial by the Air Quality Control Commission.
According to the Moffat Commission, the Clean Air, Clean Jobs Act states that it will be "implemented in a manner to address the sound economic health and environmental conditions of energy-producing communities."
Routt County commissioners voted on Wednesday to also join the opposition to switching from coal to natural gas.
Colorado Governor Bill Ritter signed the Colorado Clean Air-Clean Jobs Act in April of this year, and the legislation was supported by a broad coalition that included power companies, natural gas producers and conservationists.
