Dominion Transmission Holds Open Season to Serve the Growing Mid-Atlantic Market

CLARKSBURG, W.VA. – Dominion Transmission (DTI) is conducting an open season to solicit interest in firm transportation of up to 400,000 dekatherms of natural gas per day and firm storage service of up to 10 billion cubic feet of natural gas to serve growing local distribution companies (LDCs) and power generation markets in the Mid-Atlantic region. Dominion’s Mid-Atlantic Open Season offers shippers the opportunity to participate in an expansion of Dominion’s existing 30- and 24-inch PL-1 pipeline system, which directly serves customers in eastern Virginia, Maryland, and Washington, D.C.

Interested shippers have the option of contracting to move natural gas supplies from Dominion’s hub-like system and existing pipeline interconnects, or from an interconnect with the Cove Point pipeline in Loudoun County, Va., to any point along DTI’s PL-1 corridor extending from Perulack, Pa., to Quantico, Va. The project can be in place as early as November 2004 and can be phased to accommodate differences in the timing of customer needs.

“The level of market growth in the region clearly points to a corresponding need for additional infrastructure,” said Georgia Carter, vice president, tariff services. “Dominion’s flexible transportation and storage services have been serving the needs of LDCs and power generators in the Mid-Atlantic for over a decade. Our previously announced Greenbrier Pipeline project will serve customers in western Virginia and North Carolina. With this Mid-Atlantic Open Season, we can offer customers in the eastern part of the region new transportation and storage services that they can combine to meet their growth requirements.”

Dominion’s pipeline system has access to supply basins in Canada, Gulf Coast, Appalachia and the Mid-continent. Key receipt points include its North and South Points as well as interconnects with other interstate pipelines, including Texas Eastern, Tennessee, Transco, ANR, Iroquois, Empire and Texas Gas.

The Mid-Atlantic Project open season began at 8 a.m. EDT on June 20, 2001, and will conclude at 5 p.m. EDT on August 3, 2001. The final facilities, rates and capacity for the expansion will be determined by the results of the open season.
