Cheswick Generating Station, the last coal-fired power plant in Allegheny County, is being sold to a Kentucky-based firm for demolition, remediation and redevelopment when it shuts down at the end of March.
Charah Solutions Inc., which specializes in environmental remediation, is purchasing the power plant in Springdale and its related ash landfill and wastewater treatment plant from Houston-based GenOn Holdings, the companies announced Thursday. They did not disclose the sale price.
The properties include the primary 56-acre site, where the 565-megawatt coal-fired plant is located, as well as an adjacent 27-acre parcel that hosts a rail line, coal yard, ash handling area and several waste ponds.
The 51-year-old plant had reached the end of its expected lifespan and was the state’s smallest coal plant, operating only at peak times when the price of electricity on the grid was high.
It was also one of the county’s largest single sources of air pollution.
