I have a good flow of water but not much vertical drop, can I still install micro hydro?

‘Zero head’ turbines can be placed in rivers, or other flowing water, and will respond simply to the flow - producing a small amount of electricity for trickle-charging a 12 volt battery.

For example, the Ampair underwater generator will generate up to 100 watts in fast flowing streams.

It is also possible to purchase turbines that have been designed to be towed behind yachts.

Archimedean Screw turbines are also good for low-head situations, easpecially those with heavy debris.

See the question about converting old mill sites for more advice on 'low head' sites.

  Our consultancy service can help you establish whether a river is suitable for micro-hydro power, by assessing head and flow rates in order to make a specification of the turbine and other components.
