Supplying electrical energy to the load on demand, economically and with acceptable levels of reliability and service quality is the main task of a distribution system. Energy distribution reliability is important in the competition conditions in electricity markets because consumers directly supply energy. Therefore, it is not enough to estimate how reliable the distribution system is at present and to estimate the future reliability change in order to make optimum planning decisions, but also to provide the necessary amount of spinning reserve. The past reliability performance of distribution system can be quantified using a wide range of indices. This study is concerned with evaluating the reliability indices for only part of a network. Even though this study is limited due to unavailability as well as the inaccessibility of full and correct data over a sufficient period for analysis, it can give a clue and motive for further evaluation of the reliability of network.
