Calpine Begins Building South Carolina Cogenerator

LCG, Sept. 26, 2001--Calpine Corp. announced yesterday that construction is under way for its new 550-megawatt Columbia Energy Center, a natural gas-fired cogeneration facility located on property leased from Eastman Chemical Company near Columbia, S.C.

"This project represents another strong step forward in strengthening our solid base of energy resources in the Southeast power market," said Bob Alff, senior vice president and head of Calpine's eastern region operations. "We are well on our way toward developing the newest, cleanest and most energy efficient system of electric power resources in South Carolina and the southeast region."

The $260 million plant is expected to begin commercial operation by the fall of 2003, when it will sell power into the regional wholesale electricity market and provide process steam for the Eastman plant. During construction, about 200 workers will be on the job, and about 25 permanent, full-time jobs will be created by the plant, Calpine said.

The facility will be a combine-cycle plant employing two combustion turbines, two heat recovery steam generators and a single steam turbine. Calpine said it will manage all aspects of the project, including engineering and design, construction, fuel supply, operations and power marketing.
