Title: Electrical power generating plant

Abstract: Electrical power generating plant of the pumped storage or air storage type comprising a unidirectional turbine, a unidirectional motor/generator and a unidirectional pump or compressor, with a synchronous toothed clutch between the motor/generator and the pump or compressor. According to the invention the clutch is in an arrangement such that its coacting clutch teeth interengage automatically when the motor/generator tends to rotate in its normal direction relative to the pump or compressor, or when the pump or compressor tends to rotate in the direction opposite to its normal direction of rotation relative to the motor/generator, and the clutch is capable of being set when required to a bi-directionally free condition such that when the plant is operating in the generating mode the motor/generator can be driven by the turbine without the pump or compressor being driven by the turbine.
