Abstract

A system is disclosed for retrofitting a plurality of gas turbines for use in compression and expansion stages of a power plant. A first gas turbine is modified to perform as a motor driven air compressor compressing air and storing such compressed air in an air storage device. A second gas turbine is modified to perform as a generator driving expander in which air previously compressed is expanded in a turbine thus generating power.
