The Pennsylvania Department of Environmental Protection has issued an air plan approval for an 855-MW, gas-fired power project in Berks County, Pa., to Berks Hollow Energy Associates LLC.
The agency said in a brief notice in the Jan. 4 Pennsylvania Bulletin: “Plan Approval 06-05150A is for installation and startup of a combined-cycle natural gas fired electric generation station that is designed to generate up to 855 MW nominal, using 2 combustion turbine generators and 2 heat recovery steam generators that will provide steam to drive a single steam turbine generator. Each heat recovery steam generator will be equipped with a duct burner which may be utilized at time of peak power demands to supplement power output. The proposed project will also include a natural gas-fired fuel gas heater, a natural gas-fired auxiliary boiler; a diesel engine-driven emergency generator; a diesel engine-driven firewater pump; a multi-cell evaporative cooling tower; a cold cleaning degreaser; and emission control systems for the turbine generators, including SCR systems and oxidation catalyst systems.”
The LS Power website shows that Berks Hollow is a project of that company.
A March 2011 report to the DEP from the developer said the Berks Hollow Energy Station (BHES) will provide a nominal capacity of about 685 MW and will include a single power block consisting of two combined cycle combustion turbine generators (CTGs) and two heat recovery steam generators (HRSGs) that will provide steam to drive a single steam turbine generator (STG). Maximum peak capacity with the duct burners will be approximately 855 MW. Each CTG will be permitted to operate year-round on natural gas only.
The combined cycle unit will utilize selective catalytic reduction (SCR) to minimize emissions of NOX and oxidation catalyst to minimize emissions of carbon monoxide and volatile organic compounds.
The 2011 report said the developer wished to retain the flexibility to select either of the following options for the gas turbines: General Electric (GE) 7FA or equivalent; or Siemens SGT6-5000F or equivalent.
