Customers of National Grid NY could have additional gas supplies during winter 2017-2018 delivered by Transcontinental Gas Pipe Line Co. LLC’s (Transco) proposed New York Bay Expansion Project, which was recently filed at FERC.

The project would allow Williams’ Transco to provide an additional 115,000 Dth/d of firm service to National Grid NY, also known as the Brooklyn Union Gas Co. Transco asked the Federal Energy Regulatory Commission to authorize the project by May 1 so it can be in service by Nov. 1, 2017 [CP15-527].

New York Bay Expansion entails construction of new facilities and the abandonment of minor existing facilities, which would be replaced, the pipeline told the Commission.

Of the total project capacity, 65,000 Dth/d of firm service would be provided from Transco’s existing Compressor Station 195 in York County, PA, to an existing interconnection between Transco’s Lower New York Bay Lateral (LNYBL) and its Rockaway Delivery Lateral in New York state waters (Rockaway Transfer Point); and 50,000 Dth/d of firm service would be provided from Compressor Station 195 to an existing interconnection with National Grid NY at the Narrows meter station in Richmond County, NY, Transco said.

The Rockaway Delivery Lateral entered service earlier this year (see Daily GPI,May 13).

The New York Bay project would include compressor station modifications and additional horsepower at three existing stations, minor pipeline replacements on the LNYBL, a pressure uprate of the LNYBL, modifications at the Narrows, Morgan and Downingtown meter and regulating stations, and construction or modification of related appurtenant underground and aboveground facilities. No additional pipeline or pipeline looping is required, according to Transco.
