Moxie Freedom nears air approval for 1,050-MW project in Pennsylvania

Moxie Freedom LLC is nearing an air permit approval to construct a natural gas-fired combined-cycle power plant to produce a nominal 1,050 MW in Salem Township of Luzerne County, Pa.

The Pennsylvania Department of Environmental Protection published a notice of intent to approve this air permit in the Jan. 24 Pennsylvania Bulletin: “The project consists of two (2) identical 1 x 1 power blocks. Each combined-cycle process (CTG or CT) block includes one (1) combustion gas turbine and one (1) heat recovery steam generator (HRSG) with duct burner and one (1) steam turbine (ST). Each CT and ST train will share one common electric generator. Additionally, one (1) 1,000 kw diesel-fired emergency generator, one (1) 1,000 kw diesel-fired emergency fire water pump, two (2) CT inlet evaporative coolers (one for each CT, two (2) air-cooled condensers (ACCs) one for each HRSG, one (1) 55.4 MM BTU/hr Auxiliary natural gas fired boiler, one (1) 14.6 MMBTU natural gas fuel gas heater, lube oil storage tanks, and aqueous ammonia storage tanks are proposed to be constructed and operated. The heat input rating of each combustion gas turbine is 3,329 MMBtu/hr (HHV) or less, and the heat input rating of each supplemental duct burner is equal to 401 MMBtu/hr (HHV) or less.”

The department said it has determined that the proposed levels of the air contaminants emissions satisfy best available control technology (BACT) and Lowest Achievable Emission Rate (LAER) requirements as well as the department’s Best Available Technology (BAT) requirements.

A public hearing may be held on this permitting, if the department, in its discretion, decides that such a hearing is warranted based on the comments received. All persons submitting comments or requesting a hearing will be notified of the decision to hold a hearing by publication in the newspaper or the Pennsylvania Bulletin or by telephone, where DEP determines such notification is sufficient.

Written comments or requests for a public hearing should be directed to Ray Kempa, Chief, New Source Review Section, Air Quality Program, 2 Public Square, Wilkes-Barre, PA 18701-1915, Phone 570-826-2511 within 30 days after the publication date.

Moxie Energy LLC, which lately has been developing a couple of other gas-fired combined-cycle power projects in Pennsylvania, said about this project on its website: “Moxie Energy, through its wholly-owned subsidiary Moxie Freedom LLC, is proposing to build a natural gas power plant in Salem Township, Luzerne County, Pennsylvania to take avantage of the abundant natural gas resources in nearby areas and the skilled local workforce that has developed around the domestic natural gas production. The power plant will be fueled by only clean-burning natural gas, and will not require river water or any other large source of water typically used for cooling needs. It will consist of two combustion turbine generators that will each produce up to approximately 325 megawatts of electricity. The combustion turbines will be connected to two heat recovery steam generators where the hot exhaust gases from the combustion turbines will produce steam that will be directed to two steam turbines. The steam turbines will produce up to an additional 200 MW of electricity.”

Said the Moxie Energy website about one of its other Pennsylvania projects, the 825-MW Moxie Liberty facility in Bradford County: “Construction of the project began in August 2013 and is expected to take approximately 30 months to complete. Gemma Power Systems, LLC (a wholly-owned subsidiary of Argan, Inc.) is the EPC Contractor for the project, in a joint venture with The Lane Construction Corporation (Gemma-Lane Liberty Partners). … On August 21, 2013, Moxie Energy completed the sale of the controlling interest in Moxie Liberty LLC to Panda Power Funds, a private equity firm based in Dallas, Texas.”

The website said the third Pennsylvania project, the 825-MW Moxie Patriot LLC facility in Lycoming County, also had its controlling interest sold in 2013 to Panda Power Funds. Construction of the project began in December 2013 and is expected to take approximately 29 months to complete.
