Hydroelectric Power Micro Hydro Generator

 Hydroelectric generator

Introducing the Hurricane Micro Hydro Generator great for water wheels, and all your micro hydro projects.


Calculation Of Hydro Power. Work out how much hydroelectric power can be taken from flowing water with our new online automatic hydroelectric power calculator


Before embarking on any hydroelectric power generation project it is essential to survey the proposed site to calculate the amount of available hydro power.

The two vital factors to consider are the flow and the head of the stream or river. The flow is the volume of water which can be captured and re-directed to turn the turbine generator, and the head is the distance the water will fall on its way to the generator. The larger the flow - i.e. the more water there is, and the higher the head - i.e. the higher the distance the water falls - the more energy is available for conversion to electricity. Double the flow and double the power, double the head and double the power again.

A low head site has a head of below 10 metres. In this case you need to have a good volume of water flow if you are to generate much electricity. A high head site has a head of above 20 metres. In this case you can get away with not having a large flow of water, because gravity will give what you have an energy boost.

The key equation to remember is the following:

Power = Head x Flow x Gravity

where power is measured in Watts, head in meters, flow in liters per second, and acceleration due to gravity in metres per second per second.
The acceleration due to gravity is approximately 9.81 meters per second per second - i.e. each second an object is falling, its speed increases by 9.81 metres per second (until it hits its terminal velocity).

Therefore it is very simple to calculate how much hydroelectric power you can generate.
Let's say for example that you have a flow of 20 liters per second with a head of 12 meters. Put those figures in the equation and you will see that:

12 x 20 x 9.81 = 2,354 Watts

NEW Automatic Hydro Power Calculator

Below is our automated hydro-power calculator. Simply enter the head in meters, and the flow rate in liters per second, and the calculator will work out the amount of power carried by the water and the amount of power which can realistically be extracted from it to generate electricity.

Head: (meters), Flow Rate: (liters per second)
Hydro Power: (Watts)
At 60% system efficiency (Watts) of generated electricity
