Gulfstream Pipeline's Phase II Extension Now in Service

LCG, February 2, 2005--Yesterday the Phase II Extension of the Gulfstream Pipeline was placed into service, reaching new customers in central and eastern Florida. The 30-inch diameter, 110-mile long natural gas pipeline extension provides an additional 350 MMcf/day of new transportation service to gas markets, in particular power plants. Construction on the Florida extension began last summer and included construction in five counties: Polk, Hardee, Highlands, Okeechobee and Martin.

Gulfstream, a joint development between Williams and Duke Energy, was originally placed into service in May 2002 and is the first new natural gas pipeline into Florida in over 40 years. The pipeline, with a capacity of approximately 1.1 Bcf/day, receives gas from Mobile Bay, East Louisiana and Mississippi before crossing more than 400 miles of the Gulf of Mexico.

A key customer on the extension is Florida Power & Light, which will transport gas to its planned expansion of its power generation facilities at Martin and Manatee Stations. The Martin Station expansion, estimated to cost $500 million, calls for converting two combustion turbine peaking units, along with two new combustion turbines, into a more efficient combined-cycle plant that will provide an additional 800 MW. At Manatee Station, a new 1,100-MW, combined-cycle plant is approaching completion, at a cost of approximately $600 million.
