What is Tidal Power Generaton?

The seawater is stored inside a tidal embankment built at the mouth of a river or bay, where tides ebb and flow.
The turbines and generators produce power by exploiting the gap in the water level between the water outside and inside the embankment. It can generally be classified as one-way generation (single effect) or two-way generation (double effect).
