Williams marked the official start of construction on the Northeast Supply Enhancement (NESE) project with a groundbreaking ceremony at Floyd Bennett Field in Brooklyn, joined by federal and state officials, labor leaders and project partners. NESE is an expansion of Williams? existing Transco pipeline system across Pennsylvania, New Jersey and New York that will add 400,000 dekatherms per day of capacity ?
enough energy to serve the equivalent of 2,300,000 homes ? to help meet growing energy demand in the Northeast. With federal and state construction permits in hand, NESE remains on track to be in service by fourth quarter 2027, delivering reliable, affordable natural gas during peak demand periods for homes, businesses and critical infrastructure across the region.
NESE strengthens energy affordability, reliability and safety for the Northeast by expanding the existing Transco system to deliver dependable natural gas when it?s needed most ? especially during peak winter demand. The added capacity improves grid stability and supply security across New York, New Jersey and Pennsylvania, helping energy providers keep homes heated, businesses operating and critical infrastructure running as demand continues to grow.
Independent analysis also indicates the project would help moderate electricity costs over time by improving fuel availability and system flexibility. Construction and operation will support thousands of jobs and inject hundreds of millions of dollars into local and regional economies, providing long-term economic value through a reliable energy supply. NESE also advances environmental goals by reducing emissions and replacing higher-carbon fuels; the project is expected to reduce CO2 emissions by more than 13,000 tons and will use modern materials and electric motor-driven compressors to reduce emissions and noise compared to older infrastructure.
