Gulfstream Natural Gas System prepares for mainline extension

FERC amendment filed seeking minor modifications to Phase II construction

TAMPA, Fla., July 23, 2003 — In conjunction with its recently executed agreement to provide transportation service to Florida Power & Light Company, Gulfstream Natural Gas System, L.L.C. filed an amendment with the Federal Energy Regulatory Commission seeking minor modifications to the timing, facilities and rates previously approved for its Phase II pipeline construction.

“We are diligently preparing for the next phase of pipeline construction, which will extend Gulfstream’s reach to directly serve Florida’s east coast natural gas markets,” said Guy Buckley, Gulfstream senior vice president and general manager. “The amendment filed today keeps us moving in that direction, with no material change to the facilities or route that have already been evaluated by the Commission.”

Specifically, the amendment:

* Increases the diameter of a five-mile segment of pipe in Martin County from 24 inches to 30 inches.

* Anticipates construction completion of certain Phase II facilities required to serve FPL’s Martin power plant by fourth quarter 2004. Those remaining facilities in St. Lucie, Martin and Palm Beach counties would be identified as Phase III to be placed into service by February 2006.

* Modifies the initial recourse rates to reflect updated construction costs.

Gulfstream’s Phase II pipeline construction will extend its Florida mainline by approximately 110 miles from Polk County to FPL’s Martin power plant in Martin County. Gulfstream anticipates Phase II construction to begin next spring.

The Phase II construction is part of a 23-year agreement for Gulfstream to provide up to 350 million cubic feet per day of firm natural gas transportation to serve FPL’s Martin and Manatee power plant expansions. The two expansions are designed to provide service to an additional 400,000 electric customers beginning in mid-2005.

FERC approved the construction and operation of the Gulfstream pipeline project in February 2001. Gulfstream later received permission from FERC to phase construction — placing 581 miles in service last May.

Since the Gulfstream project was initiated in 1999, company representatives have worked with state and local officials as well as civic and community groups to share information and answer questions about the project, conducting public meetings, delivering presentations and making information available through its web site.

The Gulfstream pipeline is a joint development between Williams and Duke Energy. Additional information is available on the Internet at www.gulfstreamgas.com or by calling the company toll-free at 1-888-GAS-4-FLA.
