CLARKSBURG, W.VA. – Dominion Transmission, Inc., (DTI) has scheduled an open season to solicit interest in up to 6 billion cubic feet of natural gas storage capacity and 100,000 to 200,000 dekatherms per day of deliverability. The service will be 30-day to 60-day firm storage service available beginning in the 2004-2005 winter season for a term of up to 15 years. Storage injections must be received into Dominion’s North Point and storage withdrawals may be redelivered at numerous Dominion points, including Leidy.

Dominion’s open season offers a limited opportunity to obtain firm market-area storage on the Dominion system. This storage should appeal to marketers, power generation developers and local distribution companies (LDCs) because of its value, flexibility, and reliability. The final facilities, rates and capacity for the expansion will be determined by the results of the open season.

“DTI’s exhaustive review of market fundamentals shows that Northeast demand increases will be most efficiently met through the use of seasonal storage with short-haul pipes to market,” said Joe Kienle, director, business development, for DTI. “Unlike the long-haul pipeline or traditional 151-day service, this product is specially designed for the next phase of Northeast demand growth. Dominion, as a premier storage provider in the United States, is committed to serve this demand growth through expansion of our natural gas storage capability, as demonstrated by this open season and the recently concluded Mid-Atlantic open season.”

The open season will begin at 8 a.m. EST, April 3, 2002, and concludes at 5 p.m. EDT, May 3, 2002. Dominion anticipates that the service will be offered under terms and conditions comparable to its existing Rate Schedule GSS. Pricing for this service will be determined as a function of the mix of storage demand and capacity sought by participants in the open season.
