FERC readies enviro review on pipeline to serve Invenergy’s 1,500-MW Lackawanna project

The staff of the Federal Energy Regulatory Commission will prepare an environmental assessment (EA) on the Triad Expansion Project, involving construction and operation of facilities by Tennessee Gas Pipeline Co. LLC (TGP) in Susquehanna County, Pennsylvania, that will serve a new, 1,500-MW power plant.

The commission will use this EA in its decision-making process to determine whether the project is in the public convenience and necessity, FERC said in an Aug. 5 notice. It will take scoping commnets on what should be covered in the EA until Sept. 4.

TGP proposed in a June 19 application to construct and operate pipeline facilities, to modify existing aboveground facilities, and add new tie-in facilities in Susquehanna County. The Triad Expansion Project would provide about 180,000 dekatherms per day of natural gas. According to TGP, its project would meet the needs of a new natural gas-fired power plant to be constructed in Lackawanna County, Pa.

The Triad Expansion Project would consist of:

  • approximately 7.0 miles of new 36-inch-diameter looping pipeline in Susquehanna County;
  • a new internal pipeline inspection (“pig”) launcher, crossover, and connecting facilities at the beginning of the proposed pipeline loop in Susquehanna County; and
  • a new pig receiver, a new odorant facility, and ancillary piping at the existing Compressor Station 321 in Susquehanna County.

TGP requested the issuance of this certificate by May 31, 2016, which would allow it to complete the project in a time frame compatible with the Nov. 1, 2017, in-service date requested by Invenergy LLC on behalf of its subsidiary, Lackawanna Energy Center LLC. Lackawanna Energy Center has executed a binding precedent agreement with Tennessee for all of the transportation capacity to be created by the TGP project.

TGP proposes to provide up to 180,000 Dth per day of long-term firm transportation service to Lackawanna, which fully subscribed to the firm capacity to be created by the project, for delivery to an existing interconnection with UGI Corp. located near main line valve (MLV) 321 on Tennessee’s 300 Line in Susquehanna County. UGI will then deliver the natural gas directly to this new combined cycle natural gas-fired plant.

“The Lackawanna Plant is one of several natural gas-fired electric generation facilities replacing coal-fired and nuclear electricity generation plants in the northeastern United States,” the application noted. “Tennessee’s interstate pipeline system is fully subscribed in the region of Pennsylvania where the Project is located. In order to meet Lackawanna’s demand for transportation service, Tennessee proposes to create approximately 180,000 Dth per day of additional firm west-to-east natural gas transportation capacity on its 300 Line from a mutually agreeable receipt point located at or near mainline valve (‘MLV’) 320 to the UGI Penn/TGP Uniondale Meter delivery meter (Meter #420203), both located in Susquehanna County, Pennsylvania. The Project, as designed, will provide the firm transportation capacity requested by the Project Shipper. The Project will assist with the Commission’s goal of providing more natural gas to electric generation facilities by increasing access to firm natural gas supplies in constrained northeast markets.”

UGI Utilities announced April 7 that it had signed an agreement with Lackawanna Energy Center LLC to provide natural gas service to this power project. To handle this deal, UGI will upgrade 19 miles of existing pipeline and construct approximately three miles of new pipeline.

The Pennsylvania Department of Environmental Protection said in a notice in the Aug. 1 Pennsylvania Bulletin that it intends to issue an air permit to Lackawanna Energy Center LLC for a 1,500-MW (nominal) natural gas-fired combined-cycle plant in Jessup Borough, Lackawanna County. The project consists of three identical 1×1 power blocks. Each combined-cycle process block includes one General Electric Model 7HA.02 natural gas-fired combustion turbine (CT) and one heat recovery steam generator (HRSG) with duct burners with all three blocks sharing one steam turbine.
