SUNY Stony Brook, Calpine to Boost Long Island Power Supply

LCG, January 22, 2003--An 80-megawatt expansion of the existing Bethpage cogeneration plant on the State University of New York at Stony Brook campus is planned, based on talks between Calpine Corporation, the Long Island Power Authority (LIPA), and the university.

The project will increase the efficiency of the plant, which underwent minor expansion last summer, while allowing LIPA to purchase even more of the excess electricity not used by university facilities. The cogeneration plant, built in 1995, now has a 45-megawatt capacity, and can supply steam to the university, which has 22,000 students. The plant will be expanded first in August, with a new 45-megawatt LM6000 turbine, which will be used in peaking mode.

The second phase of expansion will take place in summer 2004, when the operation of a new steam turbine will provide an additional 35 megawatts, and allow the two newest generating unit to operate in a baseload, combined-cycle mode. The project requires some remaining approvals from the state and other local governments. "The project is a win-win situation. It will provide the campus with a reliable and cost-effective power supply well into the future and will help alleviate the current power shortage on Long Island," said Stony Brook president Shirley Strum Kenny.
