PUMPED HYDRO STORAGE

Another prominent energy storage technology is pumped hydro storage. This method operates by utilizing two water reservoirs located at different elevations. During periods of low energy demand, surplus electricity is used to pump water from the lower reservoir to the upper one. When the energy demand escalates, water is released back down to the lower reservoir, passing through turbines to generate electricity.

Pumped hydro systems excel at providing large-scale energy storage solutions and can discharge electricity much faster compared to other forms of storage. This characteristic makes them particularly valuable for addressing sudden spikes in demand. Additionally, the longevity and minimal degradation of infrastructure in pumped hydro storage can lead to significant cost efficiencies over time.
