FERC seeks input on enviro review for gas pipeline to Pa. power plant

The Federal Energy Regulatory Commission is out for comment until Jan. 27 on a draft environmental assessment for a gas pipeline that would supply the repowered Sunbury plant in Pennsylvania.

On July 1, 2015, UGI Sunbury LLC filed an application with FERC for a Certificate of Public Convenience and Necessity authorizing the proposed Sunbury Pipeline Project to provide natural gas to the planned Hummel Station Generating Facility in Snyder County, Pennsylvania, as well as to UGI Energy Services LLC and interconnects to two other existing pipelines.

The project would include the construction and operation of approximately 34.4 miles of 20-inch-diameter pipeline and related facilities in Snyder, Union, Northumberland, Montour and Lycoming counties, Pennsylvania. 

Sunbury states that the primary purpose of the project is to bring natural gas service to the power plant that is proposed at the existing coal-fired Sunbury Generation Facility near Shamokin Dam in Snyder County, Pa. On May 5, 2015, Hummel Station LLC received a Major Facility Plan Permit Approval for the Hummel Station Generation Facility. The pipeline project would also provide gas service at two additional delivery points along the proposed pipeline route in Northumberland and Snyder counties.

The project would receive gas from an interconnect with Transcontinental Gas Pipeline Co. LLC (Transco) and MARC I Pipeline, operated by Central New York Oil & Gas Co. (CNYOG), both in Lycoming County.

Sunbury entered into a precedent agreement with a foundation shipper, Hummel, for 180,000 decatherms per day (176 million cubic feet equivalent per day) of firm transportation capacity. Sunbury held a binding open season from Jan. 7, 2015, through Jan. 16, 2015 to solicit additional firm shippers for the project. Binding bids in the amount of 200,000 Dth/d of capacity were received in the open season.

The project would provide capacity of about 200,000 Dth/d (195 MMcf/d) with Sunbury’s target in-service date of Feb. 1, 2017.

In other recent news for the power project:

  • Bechtel said Oct. 28 that it has been selected by Panda Power Funds to build a new 1,124-MW combined-cycle facility as part of one of the largest coal-to-natural gas power site conversion projects in the United States. The 400-MW, 65-year old Sunbury coal plant was retired in 2014. Bechtel is providing project management, engineering, procurement, construction, and startup services for the new power plant, while its consortium partner, Siemens, is responsible for the primary power generation technologies, including the combustion and steam turbines, generators, and heat recovery steam generators.
  • Siemens on Oct. 28 separately announced that it will be the technology partner for the Hummel Station. Slated for operation in the first quarter of 2018, the facility will be based around a power island consisting of: three SGT6-5000F gas turbines, one SST6-5000 steam turbine, three SGen6-1000A air cooled generators as part of the gas turbine package; one hydrogen cooled SGen6-2000H generator as part of the steam turbine package; three NEM DrumPlus HRSGs; and the SPPA-T3000 control system.
