About the project

The affordability and abundance of natural gas has created tremendous opportunities for consumers across the Eastern United States to access this clean-burning, low emissions energy resource. New York City, in particular, has experienced its cleanest air in over 50 years thanks to increased natural gas use.

Williams’ Transco natural gas pipeline 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 the existing Transco facilities 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.

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.

With natural gas’ relatively lower-carbon emissions (compared to higher-carbon fuel sources), this project has the potential to displace up to 15.6 million tons of CO2 – which is like removing 3 million passenger cars from roadways – annually.
