Hence, energy storage is only performed for the operation of the plant itself to shift the purchase of electric energy from peak to low-cost hours. Compressor C and expander E share an unrestrained rotation speed, and hence they may conveniently adapt to the variable compression/ expansion ratio along the charging/discharging cycle.
