1-800-346-9140 • www.attra.ncat.org A project of the National Center for Appropriate Technology By Leif Kindberg NCAT Energy Specialist Published February 2011 © NCAT IP383 Contents Micro-Hydro Power: A Beginners Guide to Design and Installation Introduction ......................1 Determining the Hydro Potential of Your Site .........................2 Environmental Impact .................................9 Regulatory Issues ..........11 Equipment ...................... Micro-hydro systems generally consist of the following components: • A trash rack, weir, and forebay to pre-vent debris from entering the pipeline and turbine • A pipeline (also called a penstock) to pipe water to the turbine • A powerhouse that contains the turbine and electronics • A water turbine that converts the kinetic energy of the fl owing water into mechanical energy that can be used directly or to drive a generator or other piece of equipment—this is the main component of a micro-hydro system • A tailrace to release the water back into the source it came from • Transmission lines to deliver electrical power where it is needed Th is publication is intended to include as much information as necessary to get you started in the process and to assist you generally at each step along the way of a micro-hydro project.
