Tidal Barrage La Rance Barrage

0 Comments

Tidal Barrage Ebb Generation is utilizing energy from a falling or outgoing tide. This is otherwise called as “ebb tide”. As the tide goes back to sea, it makes the opposite of previous tidal barrage scheme. During low tide, all of sluice as well as lock gates built along the barrage are left open to allow tidal basin to be filled up slowly.

Using Sea for Energy Generation

When the sea level or the ocean feeds the basin reaches the highest point during high tide, all lock gates and sluices are closed to entrap the water inside tidal basin or the reservoir. The water reservoir might keep on filling up because of streams and inland rivers that are connected to it.

Measuring the Tide

As the ocean level outside of the reservoir begins to drop on outgoing tide to its low tide mark, the difference between the actual sea level outside and the higher level of water entrapped inside the tidal reservoir now exists.

The said difference is measured vertically between the low mark and the high mark, which is called as “head height”.

There are instances in which after the start of ebb tide, the difference in head height across tidal barrage between falling tide level outside and the water inside of reservoir becomes big enough to create electrical generation process.
