Gravitational power plants
Gravitational power plants use the flow of water induced by gravity and the water cycle. Water is used directly by plants located along the water, or after storing water behind a dam for lock power stations and lake power stations.
Advantages of gravitational power plants
Plants located along the water are on the plain and use watercourses, which have a relatively constant output. Without a dam or water reservoir, plants have a lesser impact on the environment but are more dependent on precipitation. They produce low-cost electricity for basic consumption.
- Lock power stations are usually located in mountains and accumulate reserves of a maximum of 200 hours of energy production behind a dam . Able to modulate their production over the week, these plants met daily consumption peaks (morning and evening) and weekly consumption peaks (weekdays and weekends).
- Lake power stations are the most impressive and are located high in the mountains. Their immense reserves exceed 200 hours of operation and are used during seasonal consumption peaks, caused by heating in winter and air conditioning in summer.
Gravitational power plants use the same principle as hydroelectric power plants (shown here in the photo) but do not have a dam or water reservoir. © fr.academic.ru
