Cheswick Generating Station Outage

Cheswick Generating Station

Alpha 3 provided planning and scheduling support for an outage at Cheswick Generating Station. Alpha 3 provided P6 scheduling support for outage planning, which included boiler reheat tube replacements, generator rotor removal and rewinding, and various balance of plant capital and maintenance work. The Cheswick Generating Station is a fully scrubbed single-unit, coal-fired generation station located on an 82-acre site in the borough of Springdale, approximately 18 miles northeast of Pittsburgh. Cheswick, which began commercial operation in 1970, operates as a baseload facility and has a net demonstrated capacity of 570 megawatts. Since the station’s initial commissioning, additional environmental control systems have been installed to comply with more stringent emission requirements. Emissions controls include the flue-gas desulfurization (FGD) system (scrubber) designed to remove at least 98 percent of the sulfur dioxide from the exhaust, as well as reduce mercury emissions, an electrostatic precipitator and flue gas conditioning systems to remove particulate matter and a low-NOx burner system to reduce oxides of nitrogen (NOx) emissions.
