Williams Companies announced that it has secured Clean Water Act Section 401 and 404 permits from the New Jersey Department of Environmental Protection and Section 401 Water Quality Certification and related permits from the New York State Department of Environmental Conservation for its Northeast Supply Enhancement (NESE) project. The announcement was made on November 7, 2025, and the permits allow the company to move forward with a pipeline expansion that will bring natural gas into the New York City market, displacing fuel‑oil deliveries and offering a low‑cost, low‑emission alternative for the region’s power and industrial customers.
The NESE project is projected to generate more than $1 billion in investment, create over 3,000 construction‑related jobs, reduce CO₂ emissions by more than 13,000 tons per year, and deliver gas to 2.3 million homes. These figures are consistent across multiple sources, though earlier estimates ranged from $926.5 million in 2017 to $1.4 billion in 2025, and some analyses suggest the total cost to National Grid ratepayers could reach $3.2 billion. The project’s economic impact extends beyond the pipeline itself, as it is expected to strengthen Williams’ revenue base and competitive position in the Northeast.
The project’s regulatory journey has been long and contentious. Williams first proposed NESE in the early 2010s, but the project faced repeated rejections from New York and New Jersey regulators and was ultimately canceled by the company in May 2024. It was revived in early 2025 after negotiations involving New York Governor Kathy Hochul and, reportedly, the Trump administration. The recent permit approvals represent a de‑risking milestone that resolves years of uncertainty and allows construction to proceed.
Williams’ Q3 2025 earnings, released the same week, showed revenue of $2.92 billion—above the consensus estimate of $2.86 billion—while adjusted earnings per share fell to $0.49, missing the $0.51 expectation. Management attributed the revenue beat to strong demand in core segments and disciplined cost management, but the EPS miss was driven by higher-than‑expected operating expenses and a one‑time charge related to the NESE project’s regulatory compliance costs. CEO Chad Zamarin emphasized that the company remains focused on delivering clean, reliable energy while maintaining financial discipline.
The NESE project has attracted significant environmental opposition. Critics argue that the pipeline locks the region into fossil‑fuel dependence for decades and poses risks to marine ecosystems and water quality. Williams counters that the project displaces higher‑emitting fuel oil, reduces overall emissions, and supports energy affordability for New York City residents. The company’s management has highlighted the project’s role in meeting the city’s climate goals while also addressing the economic and reliability needs of its customers.
In summary, the NESE permit approvals mark a pivotal moment for Williams Companies, enabling a major infrastructure investment that aligns with its growth strategy in the Northeast. The project’s completion will enhance the company’s revenue stream, create jobs, and contribute to regional emissions reductions, while also navigating ongoing environmental and regulatory scrutiny. The company’s recent earnings performance and management commentary suggest a cautious but optimistic outlook as it moves toward construction and operation of the pipeline.
