Reservoir hydropower plants, including dams that enable the storage of water for many months, account for half of net hydropower additions through 2030 in our forecast. Cost-effective electricity access, cross-border export opportunities and multipurpose use of dams are the main drivers of the expansion of reservoir projects.
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 hydropower can deliver sustainability benefits but requires ''careful upfront co-ordination to avoid complications'', write Alan Brent and Gregory Guyot.
To replace this capability with storage would require the buildout of 24 GW of 10-hour storage—more than all the existing storage in the United States today. Additionally, in terms of integrating wind and solar, the flexibility presented in existing U.S. hydropower facilities could help bring up to 137 gigawatts of new wind and solar online by 2035.

The principle of pumped storage is fairly simple – utilising gravitational potential to store energy. Two reservoirs, one more elevated than the other, and a system of tunnels and pipes connecting them are needed. When demand is low and electricity is cheap the plant uses energy to pump water from the lower reservoir to the upper reservoir.
