The Ludington Pumped Storage Plant generates hydroelectricity on the shores of Lake Michigan, reducing our net carbon emissions while providing enough energy to power cities across the state.
Pumped storage hydro (PSH) involves two reservoirs at different elevations. During periods of low energy demand on the electricity network, surplus electricity is used to pump water to the
Water is pumped from the lower reservoir up into a holding reservoir. Pumped storage facilities store excess energy as gravitational potential energy of water. Since these reservoirs hold such large volumes of water, pumped water storage is considered to be a large scale energy storage system.
Pumped storage facilities are built to push water from a lower reservoir uphill to an elevated reservoir during times of surplus electricity. In pumping mode, electric energy is converted to potential energy and stored in the form of water at an upper elevation, which is why it is sometimes called a “water battery”.
Pumped-storage hydroelectricity (PSH), or pumped hydroelectric energy storage (PHES), is a type of hydroelectric energy storage used by electric power systems for load balancing. A PSH system stores energy in the form of gravitational potential energy of water, pumped from a lower elevation reservoir to a higher elevation.
(PHES) Energy used to pump water from a lower reservoir to an upper reservoir Electrical energy input to motors converted to rotational mechanical energy Pumps transfer energy to the water as kinetic , then potential energy K. Webb ESE 471 6 Pumped-Hydro Energy Storage
Pumped storage facilities store excess energy as gravitational potential energy of water. Since these reservoirs hold such large volumes of water, pumped water storage is considered to be a large scale energy storage system. These pumped storage facilities are moderately efficient, with a round-trip efficiency of about 65-70%.
The amount of energy stored depends on the mass of water pumped and the height difference between the reservoirs. Pumped storage is a dispatchable source of energy since it can be deployed whenever demand is needed. It is often used to meet demand when intermittent, non-dispatchable sources, such as wind and solar power, cannot do so.
