Dominion Transmission, the natural gas transportation subsidiary of Dominion, has placed its Appalachian Gateway Project into service. 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 pipeline will deliver coal bed methane and Marcellus shale in the Appalachian region into an interconnect with Texas Eastern Transmission in Delmont, PA.
For the Appalachian Gateway Project, the company constructed four new natural gas compressor stations and upgraded two existing compressor stations, adding about 17,800 horsepower. About 110 miles of new pipeline were constructed, beginning in West Virginia and terminating at Oakford facility in Delmont, Pa., east of Pittsburgh.
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 the utility’s Hastings Extraction Plant in Pine Grove, W.Va.
