Planning of the southern Nigeria power system network cannot be ignored because of the economic importance of the region to the country. The power flow analysis of the region can provide a useful tool in archiving this. With a comprehensive knowledge of the power injected and demanded from all the buses, at any point in time, the various bus voltages can be computed and used in planning the system. Analysis of data collected at a particular day (bus power and line parameters) from the PHCN produced the voltages of the buses in the region and shows that Akamgba, Egbin transmission station, Ikeja West, Aladja and Alaoji buses (i.e buses1, 2, 5, 8 and 12) have voltages outside the standard range of 0.95p.u – 1.05p.u (i.e 313.5kV – 346.kV for a 330kV base voltage). Planning the region in terms of increasing generation capacity will be centered on these buses if the results persist. Increasing the generation capacity of the network will mainly favor these buses.
