Pico hydro – Reducing technical risks for rural electrification

Very small hydropower (pico hydro) schemes, with an output of less than 5kW, can be a cost-effective option for the electrification of remote rural communities. Despite the fact that each hydropower site is unique, there is potential for using standardised equipment and low-cost approaches to scheme design. Relatively low equipment costs are possible, particularly if locally manufactured in a developing country, which enable costs per unit of energy output to be lower than small petrol or diesel generators, wind turbines or PV systems.
