HOUSTON - Iroquois Gas Transmission System, Duke Energy and Williams have announced plans to develop a natural gas pipeline to serve markets in New York and Connecticut.

The proposed Lighthouse Pipeline System is designed to extend under the Long Island Sound to transport U.S. and Canadian natural gas from Williams’ Transco pipeline, Duke’s Algonquin and Texas Eastern pipelines and the Iroquois pipeline system to southern Connecticut.

The new pipeline system, proposed to have an initial capacity of 350,000 dekatherms per day (Dth/d), will primarily supply natural gas to electric generating facilities built along its route in Southern Connecticut and facilitate the development of low-cost power generation on Long Island.

"This project adds new dimensions to Iroquois’ pipeline network and provides important new opportunities for our customers," Craig Frew, president of the Iroquois Pipeline Operating Company, observed. "The Lighthouse Pipeline will create new competitive and diversified markets for U.S. and Canadian supplies of natural gas in a region already engaged in growth and change."

"This innovative partnership gives Transco a new opportunity to serve the thriving New England market," said Cuba Wadlington Jr., senior vice president and general manager, Williams’ Transco pipeline system.

"The creation of Lighthouse complements the recently announced Cross Bay Pipeline, which has been designed to provide up to 700,000 dekatherms per day to the New York City market. Together, we believe these projects exhibit our unwavering commitment to satisfy natural gas demand in this market area."

"Lighthouse builds on a strategy of market-based projects that can take advantage of multiple upstream options," said Bobby Evans, president of Duke’s Texas Eastern and Algonquin systems. "This brings increased efficiencies to the interstate grid coupled with the strength of the New York market center for liquidity."

Lighthouse will be timed to meet market needs and is expected to be in service by 2000 to 2001. The facilities will consist of approximately 35 miles of new 16-inch diameter pipe in southern Long Island, and approximately 60 miles of new 24-inch diameter pipe in southern Connecticut. The Long Island segment will extend from a connection with the recently announced Cross Bay Pipeline at Long Beach, N.Y., to a connection with Iroquois at South Commack, N.Y. The Connecticut segment will originate at an interconnection with Iroquois near Milford and extend to the Millstone area near New London. Delivery locations in the Millstone area can be specified by shippers during the open season process. The configuration of new and existing facilities offers access to diverse options to meet market needs.

The approximate cost of the project is $240 million. Duke, Williams and Iroquois each plan to own one-third of the new pipeline.

A 60-day open season will be held in the early summer to determine the level of market interest. For more information about the project, contact Joan Strub at Williams 713/215-2904, Patrick Gibson at Duke 617/560-1454 or Herb Rakebrand at Iroquois 203/925-7276.
