• Garden State Expansion Project to provide additional reliability to Hurricane Sandy-affected local gas distribution along New Jersey coast
  • Project is in addition to $4.3 billion in capital expenditures planned through 2017 on Transco projects to serve growing markets along the Eastern Seaboard and Southeast U.S.

Williams Partners L.P. (NYSE: WPZ) and its wholly owned subsidiary Transcontinental Gas Pipe Line Company, LLC (Transco) today announced a fully contracted expansion project designed to deliver 180,000 dekatherms a day of additional natural gas capacity for local distribution along the Eastern Seaboard.

The Garden State Expansion Project consists of additional compression to provide 180,000 dekatherms of firm natural gas transportation service and increased reliability to a local gas distribution company along the New Jersey coast that was affected by Hurricane Sandy. The $150 million project would provide firm transportation from Transco's Zone 6 Station 210 Pooling Point in Somerset County, N.J. to a new interconnection on Transco's Trenton Woodbury Lateral in Burlington County, N.J. Williams Partners plans to place the project into service in phases with the first phase in 2016 and the second in 2017, assuming timely receipt of necessary regulatory approvals.

The project is in addition to the $4.3 billion in capital expenditures planned through 2017 on Transco growth projects that Williams Partners has previously announced. Transco is the nation's largest and fastest-growing interstate natural gas transmission pipeline system. It delivers natural gas to customers through its 10,200-mile pipeline network whose mainline extends nearly 1,800 miles between South Texas and New York City. The system is a major provider of cost-effective natural gas services that reach U.S. markets in 12 Southeast and Atlantic Seaboard states, including major metropolitan areas in New York, New Jersey and Pennsylvania.

"As demonstrated by this continued high-level of demand from customers, Williams Partners is well positioned to serve the growing electricity-generation and gas distribution needs of markets up and down the eastern United States," said Frank Ferazzi, vice president and general manager of Williams Partners' Transco system. "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."

The Rockaway Lateral and Northeast Connector expansions are among Williams Partners projects currently under construction. These two projects are designed to increase natural gas delivery capacity to Brooklyn and Queens this winter. To the south, demand for gas-fired electric power generation is the primary driver of two more Transco projects under construction - Virginia Southside and Mobile Bay South III - both designed to provide additional firm natural gas transportation 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 (FERC) seeking authorization to extend the existing Transco pipeline in order to fuel a new electric power generating facility in Cecil County, Md. The project is expected to be placed into service by third-quarter 2016.

Also in June, FERC announced a schedule showing that it expects to issue in August the environmental assessment for the Leidy Southeast Expansion project. The project is designed to increase Transco pipeline's capacity by 525,000 dekatherms of natural gas per day to serve the growing market needs along the Atlantic Seaboard by late 2015.

In February, FERC issued its draft Environment Impact Statement for the Constitution Pipeline and the company expects FERC to issue the final Environmental Impact Statement soon. Constitution Pipeline Company, LLC is owned by subsidiaries of Williams Partners L.P., Cabot Oil & Gas Corporation, Piedmont Natural Gas Company, Inc. and WGL Holdings, Inc. The 124-mile pipeline project is proposed to connect domestic natural gas production in northeastern Pennsylvania with northeastern markets by late 2015 or 2016.
