“Small hydro” covers a range of machines, usually classed by size: small up to about 10 MW, mini below 1 MW or 500 kW depending on the country, micro below 100 kW and pico below 5 to 10 kW (Small hydro; Micro hydro). Byose Bya ni Bya: Bya A, A Gitoya Inzira% s Bya A Gihinguranya A na.

The power is P = ρ × g × Q × H × η, where ρ is the density of water (1,000 kg per cubic metre), g is gravity (9.81 m/s²), Q the flow in cubic metres a second, H the head, or height the water falls, in metres, and η the efficiency of turbine, generator and pipework together. Put plainly: every cubic metre a second falling one metre carries 9.81 kW. Large turbines convert over 90% of it; small ones typically 50 to 85% (Micro hydro).
