Such complexes are called "pumped storage plants". In the area of energy storage, they are definitely the record-keepers. Energy can be stored in other ways, in electric batteries, or thermally in huge reservoirs of molten salts or as compressed air, (the Chapter 11 in this text is devoted specifically to energy storage methods).
