A hydroelectric power station can generate electric power by using the energy of water flowing from high level to low level. It works different functions in day and night.
In the day time, water in the high-level reservoir go through the intake under the dam which is only open in day time. Then the water flow into the power station in which there is a generator The generator is operated by a reversible turbines that can transfer the water flowing force to the mechanical force which is the power of the generator. The generated electricity then goes to the national grid through the power lines.
On the other hand in the night time, the power station works in a reversed way. It pumps water from the low-level reservoir to high-level reservoir to provide the enough water for day time's work. The water is pumped by the same reversible turbines from low-level reservoir. So the power station actually consumes energy at night. But that is in order to generate more power in the day time.
In a conclusion, a hydroelectric power station can generate power is based on the differce heighth of water level. In day time, it uses the natural water energy. Meanwhile in the night, it transfers the water to create and store the energy for the next day.
