Pumped storage hydropower is a form of hydroelectric storage and they are used for electric power systems for load balancing.
Explanation:
It is a type of hydroelectric energy storage that contains two water reservoirs at different elevations which generates power in the water moves down through turbine and it takes the power as it pumps water to upper reservoir.
The altitude may diminish the pump's performance based on the principles of specific gravity, atmospheric pressure and oxygen deprivation.
The specific gravity and pressure based on altitudes suggests that water can be pumped up to 26 feet down when operating a pump at sea level because of atmospheric pressure. The depth shows that altitude increases because of decreasing atmospheric pressure. The pump operators are server to locate their pump close to the source of water you are pumping. The elevation impacts to suction lift.
