Williams Puts Another East-Coast Gas Pipeline into Service

Tulsa’s Williams Partners L.P. announced this week it has put into service an expansion project of one of its natural gas lines along the east coast.

The expansion applies to the Virginia Southside II project, the fifth of Transco’s “Big 5” expansions to enter service this year, according to the announcement. The five fully-contracted expansion projects combine to add more than 2.8 million dekatherms a day to the Transco pipeline system this year. It also increased Transco’s design capacity by nearly 25 percent.

“The Virginia Southside II project was placed into service on time and under budget and highlights our continued execution on growth projects,” said Alan Armstrong, chief executive officer of Williams Partners’ general partner.

The Virginia Southside II project will help supply Dominion Virginia Power’s new electric generation facility in Greensville County, Virginia.

Another project, the Atlantic Sunrise line is on schedule to be operational in 2018. Once operational, it will increase deliveries by 1.7 million Dth/d as it connects Marcellus gas supplies with markets in the Mid-Atlantic and Southeastern U.S.

Transco is considered the nation’s largest-volume and fastest-growing interstate natural gas pipeline system and is a wholly-owned subsidiary of Williams Partners L.P. It has a network consisting of 10,200 miles of pipeline including a mainline that extends nearly 1,800 miles from South Texas to New York Ci ty.
