Storage hydroelectric is sometimes also known as ''impounded power''. A natural loch or man-made reservoir formed by draining a river collects water from the surrounding area, which can be hundreds or even thousands of square kilometres in size. What is created is a store of water situated at a higher altitude than the power station it supplies.
