Farm hydropower projects have existed for many years, from waterwheels used for grinding grain and forging to modern hydroelectric turbines designed to run compressors and motors. Micro-hydro systems — those that produce less than 100 kilowatts of electricity — can offer a sustainable and continuous source of renewable energy on farms. This publication is designed to introduce the reader to all stages of a micro-hydro project — from first considering the idea all the way through to producing power.
