Washington — Progress Energy's power plant in Person County is among the 50 dirtiest plants nationwide, according to a report released Thursday by an environmental group.
The Progress Energy plant at Hyco Lake is No. 25 on the list compiled by the Environmental Integrity Project. Duke Energy plants in Stokes County and Catawba County are ranked 28th and 46th on the list, respectively.
The "Dirty Kilowatts" rankings are based on the amount of pollution released by each plant.
Progress Energy officials said they have been installing technologies since the 1990s to reduce emissions from the Person plant. By 2013, the company expects to reduce emissions from its North Carolina plants by 80 percent, officials said.
