Abstract
Nigerian Electric Power Utilities face epileptic power supply due to poor generation level. The available power is characterised with high losses of Aggregate Technical and Commercial (ATC) or Total network losses. These losses have serious effects on the quality of power delivered to customers and adverse effect in meeting the expected revenue targets. Technical losses are caused by network impedance due to current flowing in the network and auxiliary supplies. Whereas non-technical losses are caused by several factors which include, energy theft, unbilled accounts, non-payment of customers, estimated customer accounts etc. This paper presents analysis of some selected power system network for estimation of total network or ATC losses and determination of network technical losses (TL) using power flow analysis. From the results of ATC losses and TL calculations, a total network non-technical
loss (NTL) is determined.
