TULSA, Okla. -- (Business Wire)

Williams Partners L.P. (NYSE: WPZ) announced today that it is initiating a binding open season from April 4 to April 25, 2012, for an expansion of its Transco interstate pipeline to provide incremental firm natural gas transportation capacity to markets in southern Virginia and northern North Carolina by 2015.

Williams (NYSE: WMB) owns 72 percent of Williams Partners, including the general-partner interest.

The Virginia Southside Expansion Project is being designed to provide incremental firm transportation service on the Transco pipeline from its existing Zone 6 Station 210 pooling point in Mercer County, NJ, to delivery points along Transco’s South Virginia Lateral. The company has executed a precedent agreement to provide Dominion Virginia Power with 250,000 dekatherms per day of the capacity and will solicit bids in the open season from shippers for additional deliveries along the project path. The proposed in-service date is September 2015.

Dominion Virginia Power would use its capacity for a 1,300-megawatt, combined-cycle, natural gas-fired power station that it plans to build in Brunswick County, Virginia.

“Williams is excited by this opportunity to partner with Dominion to serve Virginia's power needs and open this part of the Commonwealth to additional economic development,” said Randy Barnard, president of Williams Partners’ natural gas pipeline business.

The capacity, scope and cost of the project will be determined by the results of the open season. The proposed project will be subject to approval by the Federal Energy Regulatory Commission and other agencies. For customer inquiries, contact James Corley at (713) 215-4607.

The Transco pipeline is an approximate 10,000-mile transmission pipeline system which transports natural gas to markets throughout the northeastern and southeastern United States. The current system capacity is approximately 9.6 million dekatherms per day.
