UGI Development nears air permit approval for 175-MW gas project

The Pennsylvania Department of Environmental Protection intends to approve air permitting for UGI Development Co. covering new gas-fired capacity at the Hunlock power plant located in Hunlock Township, Luzerne County.

The department said in a notice in the Jan. 24 Pennsylvania Bulletin that it has received and intends to issue a Plan Approval to UGI Development for the installation and operation of equipment that includes:

  • Two General Electric LM6000 PC-Sprint combustion turbine generators (CTGs).
  • Two supplementary natural gas-fired heat recovery steam generators (HRSGs) with separate exhaust stacks, one for each Combustion Turbine (CT).
  • One STG (steam turbine generator).

The proposed emission control systems are carbon monoxide (CO) oxidation catalyst and selective catalytic reduction (SCR) systems.

A public hearing may be held, 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.

Alisa E. Harris, Vice President, Government & Public Affairs at UGI Energy Services, which has UGI Development as a subsidiary, said in a Jan. 26 e-mail to GenerationHub about this project: “The January 24 PA Bulletin notice is related to an additional unit at the station. As you know, the existing 125 megawatt (MW) plant was converted [from coal] to natural gas in July, 2011. If approved by the Pennsylvania Department of Environmental Protection, the Plan Approval will allow the UGI Development Company to construct and operate an additional natural gas-fired 175 MW electric generating unit. Based on the typical residential consumption, 175 MWs is enough electricity to serve approximately 118,000 homes.”

PJM Interconnection will determine if transmission upgrades are necessary related to the project, Harris added. The new unit is scheduled to be in service in 2018, pending all local and state regulatory approvals. Harris noted that Marcellus Shale gas is a low-cost fuel source in this region.

UGI Energy Services is a unit of UGI Corp. (NYSE: UGI).
