The bunch of slides will give you a little brief note on Tidal energy generation and its various types. Use the resource maximum.

2. What is Tidal Energy?
• Harnessing energy from the rise and fall of tides.
• Two types of tidal plant facilities.
▫ Tidal barrages
▫ Tidal current turbines
• Ideal sites : Narrow channels
{experiences high variation in high and low tides}

5. Tidal Barrage
• Utilizes potential energy
• Tidal barrages are typically
dams built across an
estuary or bay.
• Consist of turbines, sluice
gates, embankments, and
ship locks.
• One of the oldest methods
of tidal power generation-
from 1960’s

7. Tidal stream turbines
• Extracts kinetic energy from
moving water generated by tides.
• Operate during flood and ebb
tides.
• Consists of a rotor, gearbox, and a
generator. These three parts are
mounted onto a support structure.
There are three main types:
o Gravity structure
o Piled structure
o Floating structure

8. Pros and cons of both tidal power
facilities
Tidal Barrages
Advantages
•Mature technology that has been
around for nearly 50 years.
•Reliable energy source.
Disadvantages
•High costs of construction
•Environmental impacts on marine life
•Low power output in comparison to
other energy source like coal and
nuclear power plants

9. Tidal Current Turbines
Advantages
 Able to utilize both ebb and flood tides.
 Tidal current turbines are not large
massive dam structure.
Disadvantages
 Tidal current turbine technology is young
in its development.
 Installation and maintenance challenges.
 Environmental impacts are still being
tested.
