1.What is a Tide?

2.What is Tidal Energy?

The Low Tide

The High Tide

History

• First tidal Power Plant was built

by General De-Gaulle at La

Rance in 1966.

• Generates 240MW.

• The average tidal range is 8.4m .

• The maximum range is 13.5m.

Basic Principle of Tidal Power

Components of Tidal Power Plant

There are Three main Components:

1.The Power House.

2.The Dam or Barrage.

3.Sluice-ways from the basin to the sea and Vice Versa

The Power House

DAM or BARRAGE

Sluice-ways

Operation methods of utilization of

Tidal Energy

1.Single Basin arrangement

2.Double Basin arrangement

Simple single Basin Tidal System

Single ebb-cycle system

Single tide cycle system

Double Cycle System

Storage

They are mainly 4 types:-

1. Fly Wheel Storage

2. Batteries Storage

3. Hydraulic Storage

4. Compressed Air Storage

Advantages

Once you’ve built it, tidal power is free.

It produces no greenhouse gases or other waste.

It needs no fuel.

It produces electricity reliably.

Not expensive to maintain.

Tides are totally predictable.

Offshore turbines and vertical-axis turbines are not ruinously expensive to

build and do not have a large environmental impact.

Limitations

Cost of construction of tidal power plant is high.

The actual generation is for a short period of time.

This transmission is expensive and difficult.

Influences aquatic life adversely and can disrupt migration of fish
