Pumped storage hydropower is a type of hydroelectric power generation that plays a significant role in both energy storage and generation. At its core, you''ve got two reservoirs, one up high, one down low. When electricity demand is low, excess energy from the grid is used to pump water from the lower to the upper reservoir.
This methodology provides opportunity to store excess energy of grid at the times of lower demand, lower generation cost or from intermittent energy sources and the stored energy can be utilized at the times of higher demand, ...
