"The Seneca Compressed Air Energy Storage (CAES) Project is a 130 to 210 MW Compressed Air Energy Storage plant that will consist of a separate, electrically driven compression cycle and a natural gas-fired expansion cycle energy storage plant. New York State Electric & Gas (NYSEG) will evaluate two expansion cycle designs for the plant during Phase 1 of the project and will select the most cost effective technology to proceed with Phase 2 project development should the CAES project be approved for development. The first expansion cycle to be evaluated (Cycle #1) will employ expansion turbine generators with natural gas combustors to pre-heat the storage air prior to admitting it into the expanders. The second expansion cycle (Cycle #2) to be evaluated will consist of a simple cycle combustion turbine with a waste heat recuperator downstream of the combustion turbine exhaust that will be used to pre-heat the storage air prior to admitting it into the expanders."
