patovoimalaitokset
Patovoimalaitokset, also known as pumped-storage hydroelectric power plants, are a type of energy storage system that utilizes hydroelectric power. They consist of two water reservoirs at different elevations, connected by a tunnel or pipeline. During periods of low electricity demand and surplus energy, water is pumped from the lower reservoir to the upper reservoir. This process stores potential energy in the elevated water. When electricity demand is high, the stored water is released from the upper reservoir back to the lower reservoir through turbines, generating electricity.
The primary function of patovoimalaitokset is to balance the intermittent nature of renewable energy sources like
