Hydropower
Hydropower is one of the crucial technologies for fulfilling a commitment to reach 500 GW of non-fossil electricity capacity in 2030. Europe commissioned almost 2 GW of pumped storage hydropower capacity in 2022, the largest amount since at least 1990. Two projects in Switzerland and Portugal aim to facilitate integration of solar PV and wind.
Europe hydropower regional profileEurope
In 2022, Europe suffered from droughts that lasted for the first three quarters of the year, causing a decline in hydropower energy production. The situation improved in 2023 when hydropower generation bounced back, reaching 637.23TWh. This is almost level with the 2020 and 2021 average of 666.5TWh.

OverviewPotential technologiesBasic principleTypesEconomic efficiencyLocation requirementsEnvironmental impactHistory
Pumped storage plants can operate with seawater, although there are additional challenges compared to using fresh water, such as saltwater corrosion and barnacle growth. Inaugurated in 1966, the 240 MW Rance tidal power station in France can partially work as a pumped-storage station. When high tides occur at off-peak hours, the turbines can be used to pump more seawater into the reservoir than the high tide would have naturally brought in. It is the only larg…

term energy storage at a relatively low cost and co-benefits in the form of freshwater storage capacity. A study shows that, for PHS plants, water storage costs vary from 0.007 to 0.2 USD per cubic metre, long-term energy storage costs vary from 1.8 to 50 USD per megawatt-hour (MWh) and short-term energy storage costs
Hydropower Basics | NREL
So-called pumped storage hydropower—also known as water batteries—can hold huge amounts of renewable energy for months at a time. This storage is very important. Solar energy and wind power only create electricity when the sun shines and winds blow, but water batteries can store excess energy that can be used at night or during gentle ...
