Northeast Supply Enhancement

Williams is developing a pipeline project to expand its existing Transco transmission system to meet the increasing demand for natural gas in the northeastern United States for the 2019/2020 winter heating season.NESE map

The proposed Northeast Supply Enhancement project would add natural gas pipeline infrastructure in Pennsylvania, New Jersey and New York — providing increased access to natural gas supply critical to help the region meet its clean air goals.

The project is designed to provide customers access to an additional 400 million cubic feet of natural gas per day (enough natural gas to serve the daily needs of about 2.3 million homes). With natural gas’ relatively lower-carbon emissions (compared to higher-carbon fuel sources), this has the potential to displace up to 15.6 million tons of CO2 – which is like removing 3 million passenger cars from roadways – annually.


Service to the Northeast

The Northeast Supply Enhancement project will provide service to National Grid – the largest distributor of natural gas in the northeastern United States. Once complete, the project will serve growing natural gas demand in the Northeast, including the 1.8 million customers served by National Grid in Brooklyn, Queens, Staten Island and Long Island.

New York’s appetite for natural gas is increasing as consumers continue to phase out the use of heavy fuel oils. In April 2015, New York City Mayor Bill de Blasio announced sweeping goals to curb city emissions 80 percent by 2050, which includes phasing out the use of No. 4 fuel oil by 2030. The Northeast Supply Enhancement project creates energy infrastructure to provide access to important natural supply necessary to help meet these aggressive clean air goals.


Project Scope

NESE offshore thumbWilliams is proposing to add about 35 miles of pipeline and new compression to its existing Transco pipeline system. This includes:

  • Twenty-two miles of 26-inch pipe in the New York Bay (offshore)
  • Three and a half miles of 26-inch pipe in Middlesex County, New Jersey (onshore)
  • Ten miles of 42-inch pipe in Lancaster County, Pennsylvania
  • A new compressor station in Somerset County, N.J.
  • Other existing compressor facility modifications

Regulatory Process

Before Williams can modify or construct any new pipeline facilities, the company must obtain a Certificate of Public Convenience and Necessity from the Federal Energy Regulatory Commission (FERC), in addition to various other permits (click here to view a list of major permits required for the project).

The project was pre-filed with FERC in May 2016 (Docket No. PF16-5). All documents and correspondence submitted to or issued by FERC regarding the project can be accessed by referencing the docket number on FERC’s website.

Williams intends to file a Certificate Application with FERC in the spring of 2017. FERC will prepare an environmental assessment of the project using information included in the Certificate Application. If FERC determines that the project is environmentally acceptable – and is satisfied the project is in the public interest – it will issue Williams an order granting a Certificate of Public Convenience and Necessity.

In lieu of sending written or electronic comments to FERC, the agency will be hosting four public scoping sessions in the project area from 5 to 9 p.m.
