What is a storage hydroelectric system?

Storage hydroelectric systems store water for later use, which makes them a versatile resource for the grid. For example, large hydroelectric dams can be sited on rivers with valleys, creating an artificial lake or reservoir. Turbines and generators in the powerhouse generate electricity when water flows from higher-to-lower elevation.
