Williams Partners received Federal Energy Regulatory Commission (FERC) approval to expand Transco, the nation’s largest natural gas pipeline system, to provide service to a new, gas-fired, power-generation plant in Virginia. The approximately $300 million Transco Virginia Southside Expansion is designed to provide 270,000 dekatherms per day (dth/d) of incremental transportation capacity in Virginia and North Carolina by September 2015. Of the total expanded capacity, more than 90 percent will serve Dominion Virginia Power’s new power plant; the remainder will serve Piedmont Natural Gas Company’s local-distribution business in North Carolina. The Virginia Southside Expansion is part of $2.2 billion of Transco growth projects that Williams Partners has previously announced it plans to bring into service between 2013 and 2017.
