An affiliate of Maryland-based Competitive Power Ventures (CPV) has applied for air permits for a proposed 700-MW combined-cycle power plant in New Jersey.
CPV Shore LLC is seeking a federal Prevention of Significant Deterioration of Air Quality (PSD) permit, a Title V State Operating Permit and an Acid Rain permit to construct and operate the 700-MW, gas-fired Woodbridge Energy Center (WEC) in Middlesex County, N.J.
The New Jersey Department of Environmental Protection is taking public comment until July 20 on draft versions of these permits, with a July 9 public hearing planned for Fords, N.J. The facility would be owned and operated by Competitive Power Ventures Shore LLC, also known as CPV Shore LLC.
WEC will be a combined-cycle facility consisting of two General Electric (GE) 207FA.05 combined cycle combustion turbine generators (CTGs), two heat recovery steam generators (HRSG) equipped with duct burners, one steam turbine electric generator (STG), one 14-cell (2×7 configuration) wet mechanical draft cooling tower, and ancillary equipment. The CTGs and duct burners will use natural gas as fuel. Each combustion turbine will have a maximum rated heat input of 2,307 MMBtu/hr, based on higher heating value of fuel (HHV) (not including supplemental duct-firing), and a maximum heat input rate of 2,807 MMBtu/hr HHV with supplemental duct-firing, said a DEP fact sheet. The combined maximum hourly electricity generated by the two combustion turbines will be 480 MW.
Ancillary equipment will include a 91.6 MMBtu/hr (HHV) auxiliary boiler equipped with low NOx burners that will operate on natural gas for 2,000 hrs per year or less, one small 9.5 MMBtu/hr (HHV) natural gas fired fuel gas heater operating for 8,760 hrs/yr, a 1,500 KW (13.5 MMBtu/hr HHV) emergency diesel generator, and a 315 HP (2.1 MMBtu/hr HHV) diesel fire pump.
The WEC site is in close proximity to the Middlesex County Utilities Authority (MCUA) sewage treatment plant and will use treated effluent diverted from the MCUA river discharge for non-contact cooling tower makeup. Cooling tower blow down and process wastewater could be discharged back into the MCUA facility.
“WEC has proposed to use only clean burning fuels i.e. natural gas and ULSD oil to minimize air pollutant emissions,” said the DEP. “Dry Low NOx burners (DLN) along with a Selective Catalytic Reduction System (SCR) will be installed on the combustion turbines, to comply with Best Available Control Technology (BACT) and Lowest Achievable Emission Rate (LAER) to reduce inlet NOx concentrations. WEC is also proposing the use of oxidation catalyst as BACT to reduce inlet [carbon monoxide] concentrations, and to reduce the [volatile organic compound] emissions during all steady state operations.”
The CPV website notes that the company is headquartered in Silver Spring, Md., with offices in Braintree, MA, San Francisco, CA and Toronto, Ontario. CPV currently has 5,965 MW of natural gas generation projects in various stages of development. The company’s Asset Management division has 5,000 MW of natural gas and wind generation facilities under management. CPV Renewable Energy Co. (REC) is currently developing 4,321 MW of wind power projects across North America, with plans for more.
CPV announced in March 2011 that its CPV Woodbridge Energy Center project was selected by the New Jersey Board of Public Utilities to be one of three projects that will produce in-state power to help lower electric costs for New Jersey consumers who currently pay some of the highest rates in the country. The selection was undertaken as a result of legislation (P.L. 2011) that was signed into law by Gov. Chris Christie.
In March 2012, its CPV St. Charles gas-fueled power plant was selected as a winner in the Maryland Public Service Commission’s RFP for additional in-state generating capacity. Another CPV project, the 650-MW Valley plant in New York, cleared a key regulatory hurdle in May.
