Tennessee Gas advances major pipeline project toward FERC application

Tennessee Gas Pipeline Co. LLC on March 13 filed with the Federal Energy Regulatory Commission a voluminous resource report as part of the pre-application environmental review process for its Northeast Energy Direct Project.

In September 2014, Tennessee Gas Pipeline filed a request to use FERC’s pre-filing procedures for the Northeast Energy Direct Project, which the commission approved in October. As part of the pre-filing process, Tennessee submitted various resource reports  

On Feb. 27, Tennessee received comments from commission staff on prior resource reports for the project. The commission staff requested that Tennessee incorporate the requested information in revised resource reports and to include a matrix that identifies the specific locations in the resource reports where the information requested in these comments may be found. Tennessee expects to file a certificate application for the project in September 2015. 

With this project, Tennessee proposes to expand and modify its existing pipeline system in Pennsylvania, New York, Massachusetts, New Hampshire and Connecticut. The NED Project is being developed to meet the increased demand in the northeast U.S. for transportation capacity of natural gas. The NED Project will provide up to 2.2 billion cubic feet per day (Bcf/d) of new firm natural gas transportation capacity to meet the growing energy needs in the Northeast U.S., particularly in New England.

The proposed project involves the following facilities:

  • Approximately 32 miles of pipeline looping on Tennessee’s 300 Line in Pennsylvania;
  • Approximately 133 miles of new pipeline proposed to be generally co-located with the recently approved Constitution Pipeline Project (“Constitution”) in Pennsylvania and New York (extending from Tennessee’s existing 300 Line near Auburn Center, Pennsylvania, to Wright, New York);
  • Approximately 53 miles of pipeline generally co-located with Tennessee’s existing 200 Line and an existing utility corridor in New York;
  • Approximately 64 miles of pipeline generally co-located with an existing utility corridor in Massachusetts;
  • Approximately 71 miles of pipeline generally co-located with an existing utility corridor in New Hampshire (extending southeast to Dracut, Massachusetts);
  • Various laterals and pipeline looping segments in Massachusetts, New Hampshire, and Connecticut to serve local markets;
  • Construction of nine new compressor stations and 15 new meter stations, and modifications to existing compressor and meter stations throughout the project area; and
  • Construction of appurtenant facilities, including mainline valves (MLVs), cathodic protection, and pig launchers/receivers through the project area.

To the extent that it is practicable, feasible, and in compliance with existing law, Tennessee proposes to locate proposed pipeline facilities (either pipeline looping segments or co-located pipeline facilities)4 generally within or adjacent to its existing right-of-way (ROW) associated with its existing 300 Line in Pennsylvania and Connecticut; its 200 Line in New York and Massachusetts; and existing pipeline and utility corridors in Pennsylvania, New York, Massachusetts, and New Hampshire.

Tennessee is requesting issuance of a certificate order for the project in October 2016 and proposes to commence construction activities in January 2017, in anticipation of placing the project facilities in-service by November 2018 (with the exception of two proposed pipeline looping segments in Connecticut, which would be placed in-service by November 2019).

Tennessee’s existing pipeline infrastructure consists of approximately 14,000 miles of pipeline designated as the 100, 200, 300, 400, 500, and 800 Lines, based on the region they serve. The proposed NED Project focuses on the existing 200 and 300 Lines. The 200 Line consists of multiple pipelines varying from 24 inches to 36 inches in diameter beginning on the suction of Compressor Station 200 in Greenup County, Kentucky, and extending east through Ohio, Pennsylvania, New York, and Massachusetts. The 300 Line system consists of two pipelines (24 inches and 30 inches in diameter) beginning on the discharge side of Compressor Station 219 in Mercer County, Pennsylvania, traveling east through Pennsylvania, New Jersey, New York, Connecticut and terminating as a 16-inch-diameter pipeline at Compressor Station 261 in Hampden County, Massachusetts.

Upon completion, the project will provide up to 2.2 Bcf/d of additional natural gas transportation capacity to meet the growing energy needs in the Northeast U.S., particularly in New England. This includes needs of local distribution companies (LDCs), gas-fired power generators, industrial plants, and other New England consumers. Tennessee has executed precedent agreements, for approximately 500,000 dekatherms per day (Dth/d) of long-term firm transportation capacity on the Market Path Component of the proposed NED Project, with The Berkshire Gas Co., Columbia Gas of Massachusetts, Connecticut Natural Gas Corp., Liberty Utilities Corp. (EnergyNorth Natural Gas Inc.), National Grid, Southern Connecticut Gas Corp., City of Westfield Gas and Electric Light Department, and other shippers. Negotiations continue with additional shippers for both the Supply Path and Market Path Components of the project. This project and its in-service date of November 2018 (with the exception of the two proposed pipeline looping segments in Connecticut, to be placed in-service by November 2019) are supported by the precedent agreements entered into by these shippers.
