Q. How do I know if my stream is able to power a micro hydro turbine?

 

The energy available is dependent on the rate of water flow and the vertical distance it falls (known as the head). A formula is used to establish whether or not the stream will be able to power the turbine:

Head (distance in metres) x Flow rate (in litres/second) x 9.81 = theoretical output in Watts. 

A real micro hydro system should provide about 50-60 per cent of this output.

 

Q. What is Micro Hydro and how does it work?

 

Micro hydro is simply a small scale hydro-electric power station with a small turbine being turned by flowing water.  The electricity output from micro hydro is less than 100kW and usually less than 20kW.

 

Q. How much does a micro hydro system cost and how electricity does it generate?

 

A typical 5kW domestic scale system will cost around £20,000 and generate about 8,000kWh per year. A typical house will use between 4,000kWh and 7,000kWh per year. In effect the system could generate more energy than is needed.  However the high initial cost makes micro hydro prohibitively priced for the moment.
