Micro-hydro refers to hydro power systems with a power rating of 100kW or less, which are becoming increasingly popular due to new technology, less stringent regulation of grid-connected generators and standardized turbine designs. This book provides: vital diagrams pictures and tables detailing the planning and installing of a micro-hydro installation; information on the maintenance and economics once an installation is running all relevant legal and legislative concerns with installing a small hydro installation; potential sources of support and subsidy contact details for suppliers and manufacturers. The guide is accessible, but a prior knowledge of basic engineering principles and some degree of maths competency is assumed.
