About the project

Natural gas is a critical component of the mix of energy sources necessary to meet the region’s growing energy needs. The affordability and abundance of natural gas has created tremendous opportunities for consumers in the northeastern U.S. New York City, in particular, has experienced its cleanest air in over 50 years thanks to increased natural gas use.

Williams operates the Transco pipeline – a 10,000-mile interstate transmission pipeline system which transports much of the natural gas consumed in the northeastern United States. This critical energy infrastructure reliably provides much of the natural gas consumed in the northeastern U.S. The company is currently developing the Northeast Supply Enhancement project to expand and upgrade the existing energy infrastructure in Pennsylvania, New Jersey and New York to provide consumers 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) in time for the 2019/2020 winter heating season.

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.  National Grid estimates that with the added capacity provided by the project, natural gas could displace the equivalent of 3,005,797 gallons of heating oil, reducing CO2 emissions by up to 2.4 million tons per year.

Recent cold weather and subsequent heating issues at New York City Housing Authority complexes underscores the need for heating system upgrades. National Grid is investing over more than $200 million per year to convert customers from oil to natural gas in New York City and Long Island. The Northeast Supply Enhancement project will help ensure that reliable gas supplies are available to support these conversions.
