Hydropower is the renewable energy contained in flowing water. Electricity generated using hydropower is known as hydroelectricity and is generally considered to be reliable.
In the UK there are three main methods for generating hydroelectricity:
Storage – where a dam collects water in a reservoir, then releases it to drive turbines, producing electricity
Pumped storage – where water is pumped to a higher reservoir, usually during times of low-priced electricity, then released to a lower reservoir, again driving a turbine, usually when the electricity price is higher
Run-of-river – where the natural flow of a river or stream is used to drive a turbine.
