Suitability for your property
With improvements in generator technology, small 'micro hydro' is being considered again. The viability of the installation will depend on whether there is enough water flowing per second and the height or ‘head’ that it falls from.
There should also be enough residual flow to maintain the water course. Various consents and licences are required for a hydro project.
Remember to insulate first
You should make sure that your property is properly insulated before installing renewable technologies.
