Williams Announces FERC Approval of Natural Gas Pipeline to Serve Electric Power Generating Facility in Maryland

Williams (NYSE: WMB) announced today that the Federal Energy Regulatory Commission (FERC) has approved Transco’s application to expand its mainline pipeline system and construct an 11-mile pipeline lateral connecting Transco to an electric power generating facility in Cecil County, Md.

The Rock Springs expansion project is designed to transport 192,000 dekatherms of natural gas per day to Old Dominion Electric Cooperative’s planned Wildcat Point Generation Facility. That facility is expected to generate approximately 1,000 megawatts, enough to power 390,000 homes in the region.

“The economic and environmental benefits of natural gas are driving tremendous demand for natural gas to fire electric power generating facilities like this,” said Frank Ferazzi, Vice President & General Manager of Williams’ Transco pipeline. “The Rock Springs expansion project is another in a long list of projects designed to meet growing natural gas driven power generation that Transco has completed over the past few years and is among $4.8 billion in transmission projects we expect to place into service through 2017 to meet power generation, industrial and local distribution needs.”

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.

Transco is a wholly owned subsidiary of Williams Partners L.P. (NYSE: WPZ), of which Williams owns controlling and general-partner interests.
