A system for generating electric power comprises an electrically driven air compression unit ( 10 ), a high-pressure storage tank ( 14 ) and a hydraulic system. The hydraulic system comprises a fluid reservoir ( 20 ), a pneumatically driven fluid pump ( 18 ) and a hydraulic motor ( 26 ), having a drive shaft ( 28 ) rotatably coupled to an electric generator ( 8 ). Initially a high-speed compression unit ( 10 ) is operated by an outside electric source. The air is compressed into the high-pressure storage tank ( 14 ) and controllably released into the pneumatically driven fluid pump ( 18 ), causing its operation. Hydraulic fluid being pressured from the fluid reservoir ( 20 ) into the hydraulic motor ( 26 ) causes the rotation of the motor drive shaft ( 28 ) and the electric generator ( 8 ). Electric power is generated. The outside electric source is removed. Part of the generated power is used to operate the compression unit ( 10 ) the other part of the power is used by a load.
