RICHMOND, Va. – Dominion announced today that it would conduct an open season in the first quarter of 2002 to seek customers for high deliverability storage service from its Hackberry storage facility in southwest Louisiana. Dominion will construct compressor facilities and natural gas pipelines to connect Hackberry’s existing salt caverns to several interstate pipelines in the area that carry supplies to the major U.S. markets.

“Dominion, the largest storage operator in North America with almost one trillion cubic feet of capacity, is enhancing its existing asset base by providing daily, even hourly, injection and withdrawal capability at Hackberry,” said Thos. E. Capps, chairman and chief executive officer of Dominion. “This high deliverability storage service will meet the needs of power generators in and around the Midwest-Northeast-Mid-Atlantic quadrant of the U.S. that we serve.”

The existing caverns will have a total capacity of about 17 billion cubic feet of natural gas and will deliver up to 800 million cubic feet of natural gas per day. Additional caverns on the site could be developed in the future. Dominion expects to file an application with the Federal Energy Regulatory Commission by mid-2002 to ensure in-service in 2004.

The high deliverability gas storage facility will be operated by Dominion Transmission, Inc., Dominion’s natural gas transmission and storage subsidiary headquartered in Clarksburg, W.Va.
