Foyers Pumped Storage Scheme

The Foyers Pumped Storage Project, commissioned in 1974, is the third major pumped storage scheme in the United Kingdom (UK), the second using reversible pump turbines and the first using shaft-type station construction. The paper briefly describes the station layout and plant and the various modes of operation and outlines the pump starting methods considered at the planning stage. A full description is given of the variable freauency static convertor method of pump starting adopted. The paper also describes in some detail operational experience associated with the electrical and mechanical plant since commissioning.
