New natural gas pipeline projects proposed to meet growing demand in mid-Atlantic and Northeast

BOSTON, Feb. 12, 2003 — Duke Energy Gas Transmission (DEGT) affiliates have filed two separate natural gas pipeline projects with the Federal Energy Regulatory Commission (FERC) to increase the reliability and efficiency of natural gas supplies in the growing mid-Atlantic and Northeast regions of the United States.

The projects — known as HubLine Phase II and the Dominion Expansion — also will help in the development of more flexible and economical energy transportation systems in each market, said Tom O’Connor, president of DEGT.

“DEGT is continuing its efforts to respond to the increasing demand for natural gas in these two high-growth areas — fuel that is especially critical during extended cold weather periods,” O’Connor said. “These two projects will be significant additions to the country’s energy infrastructure that will help meet the anticipated increase in natural gas for decades to come.”

On Feb. 5, the company’s Algonquin Gas Transmission unit asked FERC to amend the Certificate of Public Convenience and Necessity originally granted for the HubLine project in 2001 to facilitate development of a project that will transport eastern Canadian natural gas from the Maritimes & Northeast Pipeline to an interconnection point on the Algonquin system in Everett, Mass.

The new project — HubLine Phase II — consists of about seven miles of pipeline, called the Everett Extension, originating from Algonquin’s previously approved Deer Island Lateral in Boston to the interconnection with Algonquin, three meter stations and associated facilities along the pipeline route. HubLine Phase II will provide an additional supply source to the heart of the greater Boston market and increase the reliability of natural gas infrastructure in eastern Massachusetts.

Algonquin has asked FERC to extend the construction deadline for the Deer Island Lateral in order for the lateral to be built concurrently with the Everett Extension project. Construction is expected to begin in summer 2004 with a projected in-service date in summer 2005. More information is available at www.everettextension.com.

The Dominion Expansion Project, filed with FERC in late January by Duke Energy’s Texas Eastern Transmission, LP affiliate, consists of about 35 miles of new 36-inch diameter pipeline to be constructed within the Texas Eastern right of way adjacent to the existing pipeline. About 35 miles of an abandoned 24-inch diameter pipeline in western Pennsylvania would be removed to accommodate the larger diameter line.

Included in the project is an upgrade of some facilities at the Uniontown compressor station in Fayette County, as well as construction of the new pipeline in Greene, Fayette, Somerset, Fulton and Franklin counties. When completed, the project will transport natural gas to Dominion Transmission Inc. for delivery to markets in the mid-Atlantic region. The project is expected to be in service in November 2004.
