ABSTRACT This paper presents a feasibility study of a mini-hydroelectric power plant for seasonal base load at the main campus of University of Abuja, along Airport Expressway, Abuja, Nigeria. River Wuye assessment favoured conventional hydro power plant instead of hydro power plant technologies with out dam such as paddle wheel system as Giri river flow was low and seasonal. The electricity generation unit cost from the hydropower plant is expected to be N24.74-50.14/kWh. This feasibility work is significant as it will aid commencement of detailed project report (DPR) that will highlight detailed study of hydrology and geology, environmental impact assessment, flood control and weir structures for a hydropower plant on River Wuye at 885 kW.

# Hydropower Feasibility Study. Whether you are assessing a small private hydro scheme, a community hydropower project or a larger commercial installation, a feasibility study provides the technical and financial foundation for successful project development. Hydropower systems have to be ‘bespoke designed’ to fit into a site, rather than onto a site as is the case with wind turbines, so the site survey is a particularly important part of a hydropower feasibility study. A key element of the hydro site survey is to get a good understanding of the layout of the weir(s), channels, sluices and surrounding buildings so that some initial options for locating the hydro system can be discussed with the client. Accurate flow estimates are a vital part of our hydropower feasibility study because they form the basis of the performance and income predictions for the hydro system and are a key element when specifying the most appropriate hydro turbine.
