About the power station

Pressurised water reactor in the Daya Bay Nuclear Power Station

A pumped storage plant uses hydro technology to store energy generated by other power stations. Storage is achieved by pumping water from a lower to an upper reservoir. The stored energy can then be recovered by running the hydro units in reverse as generators. The pumped storage plant serves an important role to store surplus energy generated when system demand is low in the night and release the stored electricity when system demand is high in the day. It also serves as backup electricity capacity if other units shut down unexpectedly.
