Piedmont Natural Gas Joins Dominion in Greenbrier Pipeline

RICHMOND, Va., and CHARLOTTE, N.C. -- Piedmont Natural Gas (NYSE: PNY) has joined Dominion (NYSE:D) in a new equity venture, Greenbrier Pipeline Company, LLC, which is proposing a 263-mile interstate pipeline linking multiple natural gas supply basins and storage to growing demand in residential, commercial, industrial and power generation markets in the Southeast.

A subsidiary of Charlotte-based Piedmont Natural Gas has become a 33-percent equity owner of Greenbrier Pipeline Company. A subsidiary of Dominion retains a 67-percent equity ownership in the project. The Greenbrier Pipeline, which was originally announced by Dominion last October, will originate in Kanawha County, West Virginia, with connections to Dominion Transmission and Tennessee Gas Pipeline. The pipeline will extend through southwest Virginia and into Granville County, North Carolina. The $497 million pipeline, which will be designed, constructed and operated by Dominion Transmission, will be project-financed by the project owners.

“Piedmont’s management team is a solid, progressive, forward-thinking group that recognizes the importance of adding new energy infrastructure to a rapidly growing region,” said Thos. E. Capps, chairman, president and chief executive officer of Dominion. “We welcome Piedmont as a partner and as a customer. Greenbrier Pipeline will provide significant new competitive supply choices for consumers throughout the region.”

“Piedmont is looking forward to its association with Dominion in the Greenbrier project,” said Ware Schiefer, president and chief executive officer of Piedmont Natural Gas. “Dominion’s commitment to site generation in North Carolina will bring significant benefits to both natural gas and electricity consumers. We also appreciate Dominion’s pledge to work with the communities along the pipeline right-of-way to ensure a safe and environmentally sensitive project.”

The initial capacity of the Greenbrier pipeline will be 600,000 dekatherms of natural gas per day. Gas supplies delivered from Dominion Transmission and Tennessee Gas Pipeline into Greenbrier near Charleston, W.V., could come from the Appalachian, Canadian, Gulf Coast and Mid-Continent regions as well as make use of the vast storage services already provided by Dominion Transmission. A segment of the Greenbrier Pipeline is expected to be ready for service by the second quarter of 2005 to meet power generation market requirements, with the remainder completed by the fourth quarter of 2005 to satisfy the market requirements of local natural gas utilities. The FERC certificate application for the project will be filed in the first quarter 2002.
