Trees and creeping plants fault-events greatly impact electric power distribution system reliability. The paradigm shift from distribution monopolistic government owned power system to deregulated and industry will place high responsibility on the privatised electricity industry distribution companies that deals with customer to ensure high level of reliability than its current low reliability. In this paper, a vegetation management plan is being proposed for distribution systems to avoid the occurrence of faults due to vegetation. Historical power outage data between 2003 and 2004 were collected from the monopolistic operator of Nigerian power system. National Electric Power Authority (now unbundled and called Power Holding Company of Nigeria. (PHCN) Plc) on the four feeders. Uselu, Ugbowo, Eguadaiken and FGGC Road Feeders. These feeders radiates from 2 × 15MVA transformers, 33/11kV Ugbowo injection substation in Benin City, Edo State, Nigeria serving about 17,537 customers. The analysis was carried out using Microsoft Access database. The substation serves about 17,537 customers Vegetation fault events were found to rank first as a single fault factor when load shedding that is generation based event is removed.
