New York – Construction crews recently broke ground on a long-contested underwater pipeline segment off the coast of Brooklyn, marking a pivotal moment for the Northeast’s energy infrastructure. Williams Companies leads the charge to resurrect projects stalled for years by regulatory battles. These developments promise to deliver abundant Marcellus Shale gas to markets long starved for reliable supply.[1][2]
Spotlight on the Northeast Supply Enhancement Project
The Northeast Supply Enhancement, or NESE, project expands the existing Transco natural gas pipeline system across Pennsylvania, New Jersey, and New York. This initiative adds roughly 400,000 dekatherms per day of capacity, enough to meet the daily needs of about 2.3 million homes. A key 23-mile underwater loop runs beneath Raritan Bay, paralleling current infrastructure to channel gas toward the New York City metropolitan area.[3][4]
State regulators in New York and New Jersey granted crucial water quality permits in November 2025, reversing prior denials. The project faced cancellation in 2020 and 2024 amid environmental concerns. Now, with federal backing, teams target completion by late 2027, generating thousands of jobs and hundreds of millions in economic activity along the route.[4]
Constitution Pipeline Emerges from Hibernation
Parallel to NESE stands the Constitution Pipeline, a 124-mile, 30-inch line stretching from natural gas fields in northeastern Pennsylvania through New York’s Schoharie County. It connects to the Iroquois Gas Transmission System and Tennessee Gas Pipeline, offering up to 650,000 dekatherms per day of firm transport to New York and New England markets.[2][5]…
