The existing 161,000 megawatts (MW) of pumped storage capacity supports power grid stability, reducing overall system costs and sector emissions. A bottom up analysis of energy stored in the world''s pumped storage reservoirs using IHA''s stations database estimates total storage to be up to 9,000 gigawatt hours (GWh).

Pumped hydro storage is a technology that allows for storing excess energy during times of low demand and releasing that energy during times of high demand. This technology has several potential benefits if implemented in Sri Lanka. One of the main benefits of pumped hydro storage is its ability to store large amounts of energy for use
Pumped-storage hydropower (PSH) is a type of hydroelectric energy storage. It is a configuration of two water reservoirs at different elevations that can generate power (discharge) as water moves down through a turbine; this draws power as it pumps water (recharge) to the upper reservoir. PSH capabilities can be characterized as open

World experience is that hydro projects cost about US$2,000/kW to US$4,000/kW. The Electricity Storage Association gives a range of costs for Pumped-Hydro of US$500/kW to US$1500/kW. This project is A$744/kW. So the proposed Tantangara-Blowering facility is towards the low end of the range (if the figures are correct).
Unlike traditional pumped hydro energy storage power stations that largely rely on motion from flowing or dammed rivers, pumped hydro plants cycle water within a closed system. The amount of energy that can be stored is determined by the size of the upper reservoir – the world''s largest example is in Bath County Virginia, with 3003
