Officials from the U.S. Cabinet participated in a groundbreaking ceremony for the $1 billion Northeast Supply Enhancement (NESE) Pipeline of Williams Companies. The ceremony took place at a former World War II naval air station in Brooklyn, New York.
NESE is an expansion of Williams’ Transco pipeline system across Pennsylvania, New Jersey and New York that will add 400,000 dekatherms per day of capacity. This is enough energy to serve the equivalent of 2.3 million homes.
In November 2025, regulators from New Jersey and New York approved environmental permits needed for the project, which will deliver natural gas from Pennsylvania to New York City through New Jersey and pipelines beneath Raritan Bay and New York Harbor.
A fact sheet from Williams Companies lists the New Jersey scope of work, which includes:
New Madison Loop with 3.4 miles of 26-inch-diameter pipeline loop in Old Bridge and Sayreville
New Raritan Bay Loop with 6.2 miles of 26-inch-diameter new pipeline offshore in N.J.
2 miles of pipe in onshore Middlesex County
6 miles of offshore pipe in New Jersey waters
Construction of Station 206 in Somerset County
The fact sheet also stated that the project will provide $1.8 billion in economic development to Pennsylvania, New Jersey and New York, and directly support 2,000 well-paying jobs. It would also stimulate thousands of additional jobs for Northeast communities.
“Delivering natural gas from Pennsylvania to New York City and Long Island will lower costs while helping to meet the growing energy demand of this region,” said EPA Administrator Lee Zeldin.
“We celebrate this incredible accomplishment and will continue pursuing every way possible to make life more affordable for all Americans.”
The pipeline is expected to be in service by the fourth quarter of 2027.
