The electric utility industry is moving toward a deregulated, competitive environment where utilities must have accurate information about system performance to ensure that maintenance fund are spent wisely and that customer expectations are met. To measure system, the electric utility industry has developed several performance measures of reliability indices which include outage duration, frequency of outages and system availability. Keeping a log of outages in a distribution system is very important for the utilities to compute reliability indices and for developing operation and maintenance strategies to improve system performance. An evaluation of outage data gathered by utilities in Kano Distribution Company of Power Holding Company of Nigeria PLC for the power distribution system is presented in this paper. Causes of outages are analyzed, to determine the most significant causes. The trend in outages in different months of the year is examined. The results show that the environmental factors cause more than 50% of the outages on distribution lines.
