Dominion Virginia Power, a unit of Dominion (NYSE: D), completed installing a flue gas desulfurization system on the 344 MW Unit 5 at its Chesterfield coal-fired power plant. The plant already has a scrubber on the 693 MW Unit 6 that was placed into operation in 2008.
The remaining units at the station, the 110 MW Unit 3 and the 181 MW Unit 4, are scheduled to be tied into the new scrubber by the end of the year. The plant also has two natural gas-fired units.
Dominion in 2003 signed a voluntary pollution settlement agreement with the U.S. Environmental Protection Agency. By 2015, Dominion will have spent $3.1 billion on environmental projects at its power plants.
In addition to the scrubbers, the company has installed controls at the Chesterfield station to reduce nitrogen oxides by 90 percent and a bag house to capture particulate emissions.
