ISLANDER EAST APPLIES TO CONSTRUCT PIPELINE FROM CONNECTICUT TO LONG ISLAND

BOSTON AND NEW YORK – Islander East Pipeline Company L.L.C. has filed an application with the Federal Energy Regulatory Commission (FERC) to construct, own and operate about 50 miles of interstate natural gas pipeline that will transport natural gas to growing markets in Connecticut, New York City and Long Island, N.Y. Islander East is an equally owned, limited liability company formed between subsidiaries of Duke Energy and KeySpan Corporation.

Islander East, expected to be in service in 2003, will transport key additional volumes of natural gas to meet the energy needs of this region, which is growing at a greater rate than other parts of the country. Through interconnections to virtually every major supply basin in North America, including recently developed natural gas reserves in eastern Canada, Islander East will further supplement the natural gas supplies necessary to fuel new and existing gas-fired, electric generating plants as well as local distribution companies in the area.

"The Islander East project will help us respond to the increasing demand for natural gas in Connecticut, New York City and on Long Island," said Robert Evans, president of Duke Energy Gas Transmission (DEGT), the managing partner for Islander East. "Increased access to newly developed reserves will provide a secure, reliable source of natural gas to the area. Islander East will meet the stringent federal, state and local requirements for approval, and we will continue to work with landowners, public officials, community and environmental organizations and other interested parties throughout the FERC process."

"The environmental benefits of natural gas continue to stimulate growth in residential, business and industrial markets in the Northeast," said Robert B. Catell, chairman and chief executive officer of KeySpan. "This growth will continue as more people switch their homes and workplaces to natural gas and as new natural gas-powered, electric generating plants come on line. By bringing natural gas from a newly developed basin in Atlantic Canada, Islander East will enhance the reliability and competitive cost of energy in the New York metropolitan area. The development of Islander East is consistent with KeySpan’s strategy of increasing and diversifying energy supplies while strengthening our position in the northeast energy market."

The proposed Islander East mainline pipeline will extend from Connecticut across Long Island Sound to Wading River, N.Y., with proposed connections to KeySpan’s Long Island delivery system. Islander East facilities will consist of approximately 50 miles of new, 24-inch diameter pipeline. Additionally, Algonquin Gas Transmission Company is proposing certain upgrades to its system in Connecticut that will interconnect with Islander East – approximately 13.7 miles of existing parallel pipelines will be upgraded and a new compressor station will be constructed in Cheshire, Conn. Algonquin is a unit of DEGT.
