Transcontinental Gas Pipeline Co. LLC’s (Transco) Virginia Southside Expansion has fully entered service. The project serves power generation demand in Virginia and local distribution customers in North Carolina, parent Williams said Tuesday.

The $300 million expansion is providing 270,000 Dth/d of incremental capacity and consists of 100 miles of new, 24-inch diameter pipeline extending from the Transco mainline in Pittsylvania County, VA, into Halifax, Charlotte, and Mecklenburg counties and terminating in Brunswick County, VA. Transco also added more than 21,000 hp of compression at Station 165 in Pittsylvania County.

Last December, Transco began partial service of 250,000 Dth/d on Virginia Southside (see Daily GPI, Dec. 5, 2014; April 9, 2012).

Transco has historically transported about one-quarter of the gas consumed in Virginia and nearly all of the gas consumed in North Carolina. Virginia Southside is primarily designed to fuel Dominion Virginia Power’s new 1,300 MW power plant in Brunswick County.
