Abstract
A power generation plant with a compressed air energy storage system comprises a means to reduce the pressure of air extracted from a compressed air storage cavern for the use in a combustion turbine. The means to reduce the air pressure comprises at least one expansion turbine and means to control the size of pressure reduction. Furthermore, the expansion turbine is arranged on a rotor shaft that drives a generator. The means for pressure redact, according to the invention, avoid power losses and provide an increased overall efficiency of the power generation plant.
