Williams Holds Open Season For Western Marcellus Pipeline Project

Williams held an open season Sept. 3-29 for the Western Marcellus Pipeline Project, an expansion of the Transco interstate pipeline to provide incremental firm natural gas transportation capacity to the Mid-Atlantic and Southeast by 2018.

The project is designed to provide from 1 Bcf/d to over 2 Bc/d of capacity from receipt points in the Western Marcellus and Utica supply areas to points as far south as Transco’s Zone 3 compressor station 65 in Mississippi and as far north as the proposed Zone 6 River Road point in Pennsylvania. The project would connect Williams’ Ohio Valley Midstream processing and gathering system in northern West Virginia with the Transco pipeline, the largest volume pipeline system in the United States.

The project is being designed to consist of a Greenfield pipeline extending from the Rockies Express pipeline near Clarington, OH and Williams Oak Grove processing plant in Marshall County, WV to Transco compressor station 165 in southern Virginia. From there, mainline modifications would allow both northbound flow to the proposed River Road point and southbound flow to Station 65 for significant portions of the project capacity.

The final capacity, scope and cost will be determined by the open season.

“The Western Marcellus Pipeline Project will for the first time offer Western Marcellus and Utica producers serviced by Williams’ Ohio Valley Midstream direct access to the broad range of Transco markets in the Mid-Atlantic and southeastern states, as far south as Florida,” said Rory Miller, senior vice president of Williams’ Atlantic-Gulf Operating Area. “In addition, this groundbreaking project would provide enhanced supply access for burgeoning Louisiana and Texas Gulf Coast markets accessible through our Station 65 pool.”
