The Wyoming Public Service commission recently approved plans by Rocky Mountain Power to install pollution controls at two of the four coal-fired units at the 2,120 MW Jim Bridger Power Plant, according to the Casper Journal. The controls will bring the plant in compliance with the U.S. Environmental Protection’s regional haze standards and avoid a potential shutdown of the two units.
The rules, which are administered locally by the Wyoming Department of Environmental Quality, would have required one of the units to stop burning coal by the end of 2015 and the other by the end of 2016, according to the report. RMP previously stated the approximate cost of the project will be more than $200 million, but the final amount has not been released to the public.
Converting the two units to natural gas would have likely cost more than $1 billion, according to the Journal.
RMP spokesperson Jeff Hymas told the Journal the cost would be divided among PacifiCorp (Rocky Mountain Power and Pacific Power) customers in six states. The plant is jointly owned by PacifiCorp and Idaho Power.
