Abstract
Kenya generates 50% of her electricity demand from hydro power plants along Tana River. Micro-
hydro generation is a key contributor to future energy supply. River Nzoia is one of the
major rivers in the western region of the Country which can provide adequate hydropower generation
if detailed assessment can be carried out. The real potential of this river is yet to be
explored. This study is therefore an attempt to explore the potential for micro-hydroelectricity
generation along River Nzoia which is partly influenced by precipitation within the river basin
and gross head. Power computations that combines flow discharge and water head was used to
determine the hydropower potential of this river
