New West Virginia Natural Gas Gathering System Announced by Tenaska Midstream and Superior

OMAHA, Neb. – Tenaska Midstream Services, LLC, an affiliate of Tenaska, is participating in development of a new 16-mile natural gas gathering line to serve an area of West Virginia that has lacked adequate gas transportation infrastructure, the company has announced.

Tenaska Midstream is partnering with Superior Appalachian Pipeline, LLC (Superior), to build the gathering system to carry gas from wells in Preston County, W.Va., to the Columbia Transmission System, which serves markets in Virginia, the District of Columbia and Maryland. The system can be expanded to connect with the Texas Eastern Transmission Corporation interstate pipeline.

The line is expected to be completed during the fourth quarter of 2010.

Tenaska affiliates Tenaska Resources, LLC, and Tenaska Drilling Services, LLC, are active in the Marcellus Shale formation underlying West Virginia and Pennsylvania and have drilled seven wells to date in Preston County.

“The Marcellus Shale is proving to be a highly productive source of new gas supplies, but opportunities are constrained by the absence of modern transportation infrastructure,” said Tom Boyd, Tenaska vice president and general manager of Exploration, Production and Midstream. “This gathering line will be the first in Preston County to provide a 21st Century path to market for this important developing energy resource.”

As operator, Superior, headquartered in Tulsa, Okla., will be responsible for the day-to-day operations of the gathering system. Charles Davies, Superior’s vice president of Business Development, said, “The line already has commitments to gather gas from producers who hold some of the larger acreage positions in the county. We are actively seeking additional gas supplies from other third parties.”
