HYDRO POWER PLANT
Hydro power is by far the most long established renewable energy technology that produce useful power from an upwards of a small stream to a large scale hydro-power plant of a few hundred Mega Watts capacity. The power generation depends on the flow rate of amount of water flowing, the height through which the water falls and the force of gravity.
It reduces the pollution burden, quiet and usually unobtrusive that suffering by some other renewable such as wind power etc. With proper management, the ecological effects are minimum and normally the planning permission from the relevant authority agency may be required.
In a typical hydro-power plant, the plant will consist of following components :
- An Intake, to divert the water from the stream to the Penstock.
- A Penstock pipe, is to transport the water from the intake to the Power   House.
- A Power House, is where the generator-set and turbine are installed to   convert its water   energy into electricity.
- An Outflow, is to discharge the water back into the stream.
