Abstract

Nigeria faces an acute shortage of electricity supply and large rural populations have no access to electricity. In this work, the small hydro potential of Opeki River in southwestern Nigeria was assessed. Mean daily flow records for seven years were used to establish a flow duration curve (FDC) for the river and a medium range of heads was evaluated. Conventional power equations were adopted and modified to determine rated output (Pk), annual optimal operation period (To) and to derive power duration curve (PDC) for a proposed plant at the site of interest. The plant’s annual energy production (Ek) and capacity factor (C) were projected from the PDC. At a net head of 46.5 m, an assessment at average potential power (Pave) with a single Kaplan turbine obtained values of Pk, To, Ek and C as 8.8 MW, 148 days, 50,018 MWh, and 65.1% respectively. Assessment results showed that small hydro electric power generation from Opeki River would improve electricity supply to nearby, off - grid rural communities.
