Williams Cos. Inc. placed its 65,000-Dth/d Gateway natural gas pipeline expansion project into full service, about 11 months ahead of schedule, to meet growing demand of the fuel in the New Jersey tristate area for the 2019-2020 winter heating season.

The project is an expansion of the existing Transco pipeline system, providing the additional gas transportation service to PSEG Power LLC, which would get up to 54,000 Dth/d of gas transportation capacity, and to UGI Energy Services LLC, which would receive up to 11,000 Dth/d.

The Federal Energy Regulatory Commission in February 2019 authorized Williams Cos. pipeline company, Transcontinental Gas Pipe Line Co. LLC, to start construction of the project, with an original in-service projection of November 2020.

With this expansion, the Transco pipeline's system-design capacity is increased to 17.3 million Dth/d. The system includes approximately 10,000 miles of pipeline between South Texas and New York City, according to a Dec. 31, 2019, release.
