RICHMOND, Va., Sept. 4, 2012 /PRNewswire/ -- Dominion Transmission, the natural gas transportation subsidiary of Dominion Resources (NYSE:D), has placed its Appalachian Gateway Project into service on time and within budget. The project will allow the transport of 484,260 dekatherms per day in firm transportation of natural gas produced in West Virginia and southwest Pennsylvania to storage fields and pipelines in Pennsylvania.

"The Appalachian Gateway Project will transport natural gas produced in West Virginia and southwest Pennsylvania to where it can be sold to customers in the Northeast and Mid-Atlantic," said Thomas F. Farrell II, chairman, president and chief executive officer of Dominion Resources. "Combined with our Gathering Enhancement Project, Dominion invested more than three-quarters of a billion dollars to increase the flow of natural gas in the area. This should greatly benefit the regional economy."

For the Appalachian Gateway Project, Dominion constructed four new natural gas compressor stations and upgraded two existing compressor stations, adding about 17,800 horsepower to the Dominion system. About 110 miles of new pipeline were constructed, beginning in West Virginia and terminating at Dominion's and Spectra's jointly owned Oakford facility in Delmont, Pa., east of Pittsburgh.

The Gathering Enhancement Project is an expansion of Dominion's natural gas gathering, processing and liquids facilities in West Virginia. The project has increased efficiency and reduced high pressures in Dominion's gathering system, thus increasing the amount of natural gas local producers can move through Dominion's West Virginia system.

The Gathering Enhancement Project included a host of upgrades in Dominion's gathering pipelines and compressor stations, 50 million cubic feet per day of new natural gas processing at two new plants and expansion of Dominion's Hastings Extraction Plant in Pine Grove, W.Va.

Dominion Transmission is a subsidiary of Dominion, one of the nation's largest producers and transporters of energy, with a portfolio of approximately 28,000 megawatts of generation, 11,000 miles of natural gas transmission, gathering and storage pipeline and 6,300 miles of electric transmission lines.  Dominion operates the nation's largest natural gas storage system with 947 billion cubic feet of storage capacity and serves retail energy customers in 15 states.
