Hydroelectricity comes from flowing water, which turns turbines to generate electricity. There are two types of hydroelectric power plants:

Reservoir power plants store water upstream by building a dam. Water flow through the dam can be adjusted like a tap to generate only the amount of power needed.

Run-of-river power plants don’t use dams. Instead, water takes a detour from the river through a tube. The flow of the water in the tube produces electricity and is then sent back into the river. The amount of electricity generated depends on the flow of the river.
