The aim of this study was to characterize the operations of local power distribution networks in Nigeria. An 11 kV/0.4 kV network was selected in the South West region with a peculiarity of having its own local generators supporting the mains utility supply. The data included logged data from the power supply company and the local distribution station. Electronic mapping of the network (using Global Positioning System equipment) was carried out to establish spatial coordinates of network elements. Supply and consumer oriented reliability indices were computed for the network. Node voltages and phase currents were measured using multimeters and clamp-on meters under existing supply conditions. Power flow was calculated under ideal full loading condition in order to assess the voltage and current and losses profiles of the network. Analysis of results showed poor and unacceptable operational reliability indices values and power quality by loading and voltage requirements. Remedial measures were proposed to improve the network.
