Pumped Storage Hydropower: Advantages and Disadvantages

Pumped Storage Hydropower. High efficiency in energy storage and release, especially during peak electricity demand. Higher capital cost due to construction of reservoirs and dams, but cost-effective in long-term energy management. Potential impact on ecosystems and water flow, but generally lower than fossil fuels.

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. The method stores energy in the form of gravitational potential energy of water, pumped from a lower elevation reservoir to a higher elevation. Low-cost surplus off-peak electric power is typically used to run the …
