WILLIAMSPORT -- The Department of Environmental Protection on Wednesday issued an air quality plan approval to Moxie Liberty LLC of Vienna, Va., for construction of the first power plant in Pennsylvania to run on natural gas, including gas from the Marcellus Shale.
The plant, which will generate up to 936 megawatts of electricity, will be built in Asylum Township, Bradford County, and create 500 construction jobs at its peak.
The project consists of two power blocks, with each block including a combustion gas turbine and a steam turbine. Each combined cycle process will be able to generate up to 468 megawatts of electricity and will also include a heat recovery steam generator and supplemental duct burners.
Waste heat from the two turbine generators will be converted to steam in two heat recovery generators and piped to the turbines. A large air-cooled condenser will convert the steam to condensed water that will be sent back to the heat recovery steam generators.
DEP staff's technical review determined that the proposed levels of air emissions satisfy federal and state best available control technology and the lowest achievable emission rate requirements.
