• 5. Greater expectancy of life
• 6. Ancillary benefits: irrigation, flood control, aqua culture.
• 7. Less skilled workers
• 8. Quick response to the change of load
Disadvantages
• High capital cost, power dependent on quantity of water
available, site selection dependent on water availability, long
erection time, disturbed ecology of the area.
