Abstract: Wind energy is one of the fastest growing technologies in the energy generation industry nowadays. The erratic and epileptic state of power supply in Nigeria resulting from insufficient generation to meet the load demands, and issues about global warming is of great concern to all. This has led to load shedding; blackout in some parts of the country lasting for hours, closure of some industries due to high operational cost. However the nation is currently diversifying its power generation capabilities through distributed generation using renewable resources. In order to ameliorate the situation, and to curb the global warming challenge, deployment of distributed generation (DG) using wind for electricity generation has become a novel idea. This is so because wind is abundantly available for all hours of the day and the resource is environmentally friendly. This paper therefore evaluated the wind energy potential of Owerri using the available data; considered how best it could be utilized to generate electricity through stand alone scheme and integration with the utility grid for most efficient operation.

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.
