Williams Completes Gateway Expansion Project Ahead of Schedule

Williams placed its Gateway Expansion into full service 11 months ahead of schedule through “expedited project execution and construction,” boosting natural gas deliveries to the energy-hungry U.S. Northeast by 65,000 MMcf/d, in time for the winter heating season.  

The Gateway project, an expansion of Williams’ existing Transco pipeline system, adds incremental firm transportation capacity to PSEG Power and UGI Energy Services to meet growing natural gas demands for New Jersey tri-state consumers. 

Construction on the Gateway Expansion began in early 2019, with an original in-service projection of November 2020. The project minimized community and environmental impacts by maximizing the utilization of existing pipeline infrastructure, Williams said, with virtually all project activities confined to Transco’s existing footprint in New Jersey. 

It increases design capacity to 17.3 Bcf/d for the Transco system, which includes approximately 10,000 miles of pipeline between South Texas and New York City. The system reaches U.S. markets in 12 southeastern and Atlantic Seaboard states, including major metropolitan areas in New York, New Jersey and Pennsylvania.
