What is the latest projected operational timeline for the Constitution natural gas pipeline, and what key condition must be met for that timeline to hold?

Williams CEO Chad Zamarin stated that the Constitution natural gas pipeline from Pennsylvania to New York 'could be operational as soon as the end of 2027, if all goes as planned,' with the most important next step being finalizing commercial agreements with the states — and specifically, accomplishing that 'within the next couple of months.'

Why were the Constitution and Northeast Supply Enhancement (NESE) pipeline projects previously canceled, and what recent federal-state development has revived consideration of these projects?

Williams canceled the Constitution pipeline in 2020 and the NESE pipeline in 2024 after years of delays in obtaining permits — especially water permits — from state regulators; in May 2025, the Trump administration used New York's reconsideration of Williams' proposed gas pipelines as part of a deal with Governor Kathy Hochul to lift a federal ban on Equinor's Empire Wind offshore wind farm, prompting New York to agree to work with the federal government and private entities on projects meeting legal requirements under state law.
