pumped-storage hydropower

Pumped-storage hydropower is a type of energy storage that uses water to balance supply and demand for electricity. During low energy demand, surplus electricity pumps water from a lower reservoir to an upper one. When demand is high, the stored water is released back down, driving turbines to generate electricity. This system acts like a battery, helping to stabilize the grid by providing power quickly when needed and storing it when there’s too much. It's an efficient way to manage variable energy sources, like wind and solar, ensuring a reliable and consistent electricity supply.
