Transcontinental Gas Pipe Line Co. LLC’s (Transco) fully contracted Garden State Expansion Project would provide 180,000 Dth/d of firm capacity to serve a region of the New Jersey coast that was walloped by Hurricane Sandy, the Williams Partners LP pipeline said Wednesday.

The project would entail additional compression and cost about $150 million. It would provide firm capacity from Transco’s Zone 6 Station 210 Pooling Point in Somerset County, NJ, to a new interconnection on Transco’s Trenton Woodbury Lateral in Burlington County, NJ. Williams Partners plans to place the project into service in phases with the first phase in 2016 and the second in 2017, assuming necessary regulatory approvals meet the timeframe.

“Garden State is another example of vital infrastructure expansions we’re pursuing as a result of the tremendous market demand we’re seeing from customers for abundant, clean-burning natural gas,” said Transco general manager Frank Ferazzi.

Customer information is not being disclosed, a spokesman said. A filing with FERC is expected to be made in February.

The project is in addition to the previously announced $4.3 billion in capital expenditures planned through 2017 on Transco growth projects. “…Williams Partners is well positioned to serve the growing electricity-generation and gas distribution needs of markets up and down the eastern United States,” Ferazzi said.

The Rockaway Lateral and Northeast Connector expansions are among Williams Partners projects currently under construction that are designed to increase delivery capacity to Brooklyn and Queens this winter (see Daily GPI, May 12; Feb. 28). To the south, demand for gas-fired power generation is the primary driver of two more projects under construction — Virginia Southside (see Daily GPI, Nov. 22, 2013) and Mobile Bay South III (see Daily GPI, April 17) — both designed to provide additional firm capacity to growing markets by 2015.

Williams Partners also has a number of projects progressing through the regulatory process. In June, Transco filed a certificate application with the Federal Energy Regulatory Commission seeking authorization to extend the existing Transco pipeline to fuel a new power plant in Cecil County, MD (see Daily GPI,June 23). The project is expected to enter service by third quarter 2016.

Also in June, FERC announced a schedule indicating it plans to issue in August the environmental assessment for the Leidy Southeast Expansion to increase Transco capacity by 525,000 Dth/d to serve markets along the Atlantic Seaboard by late 2015.
