Abstract: In North America, a mini hydro project consists primarily of the civil works which routes water to the turbine generator and the electrical hardware necessary to interface it with a utility. However, in third world installations which are isolated from electrical power utilities, the scope of a mini hydro project is amplified. In these isolated installations, the electrical designer must specify not only the hydroplant and its associated hardware, but also a diesel generator set for backup power, high voltage powerline, and low voltage distribution equipment. The designer may even have to include the interior wiring of buildings in the scope of the hydroplant project. Since working with three such projects in Kenya, Togo, and Honduras, I will describe the scope of each project highlighting design questions and selected solutions. After examining these three sites, I will attempt to develop an electrical designers checklist in outline form.
