Energy from water – Hydropower

In this factsheet, hydropower at weirs in large rivers and hydropower at weirs in streams are viewed together. The hydroelectric power stations in rivers and streams operate on the same principle, the main difference being the size of the power stations. A river hydroelectric power station consists of three elements: a lock complex to allow ships to pass through, the hydroelectric power station and an (adjustable) weir that pushes up the water, but allows the excess water that cannot pass through the power plant to go through (Witteveen+Bos & CE Delft, 2019).
