SINGLE BASIN TIDAL ENERGY SYSTEM

• Power house is situated at the mouth of single basin

• Hydraulic turbine only operates during discharge of water from basin during ebb tide. During high tidal basin is again filled.

• Power generation is intermittent.

• It cannot meet peak power demands .

DOUBLE BASIN TIDAL ENERGY SYSTEM

• System has two basins at two different levels and sluice gates are provided in tha dam.

• Upper basin is filled during high tide and lower basin is emptied during low tide. Therefore, it creates a permanent head for turbine to operate continuously.

• Power generation is continuous.

• The peak power demands can be met by pumping water by other means from lower basin to upper basin.
