Reliable generation technology in experienced hands
Stony Brook Unit 3 is proposed to be a highly-efficient, 280-megawatt, combined-cycle generating unit that will use natural gas to generate electricity. Ultra-low-sulfur distillate oil will be the back-up fuel. It is expected to operate as a baseload/intermediate generator, with an average heat rate of approximately 7000 btu/kwh, the result of efficient operation and use of cutting-edge technology.
Using F-Class combustion turbine technology, the unit will include:
- single combustion turbine/generator
- heat-recover steam generator (boiler)
- steam turbine/generator
- air-cooled condenser
Strict emissions compliance
- designed to meet Lowest Achievable Emission Rate (LAER) standard
- designed to meet Best Available Control Technology (BACT) standard
- use of selective catalytic reduction for nitrogen oxides
- use of a catalyst for carbon monoxide mitigation
Because there is already a power plant at the Stony Brook site, measures to prevent disruption of the local community's quality of life are already in place. The site is relatively isolated, which minimizes the visual and auditory impact. Unit 3 has already received approval by the Ludlow Conservation Commission and the Natural Heritage and Endangered Species Program of the state Division of Fisheries and Wildlife for mitigation measures.
