Pumped-storage power plants store electricity using water from dams. The new model for using the plants in combination with renewable energy has led to a revival of the technology. In 2000, there were around 30 pumped storage power plants with a capacity of more than 1,000 megawatts worldwide.
Pumped storage is by far the largest-capacity form of grid energy storage available, and, as of 2020, accounts for around 95% of all active storage installations worldwide, with a total installed throughput capacity of over 181 GW and a total installed storage capacity of over 1.6 TWh.
