This paper presents electrical power distribution network reliability. Reliability is one of the most critical factors of a network operating system that is supported. Several things become essential parameters in determining an index that complements the distribution system, namely SAIFI and SAIDI. This research is able to know about the high levels obtained by the distribution system at the Wates substation. With this analysis, it is expected that this will become a reference for improving service quality in the coming year. Based on the results of calculations and analyses that have been done, it can be said that the distribution system at the substation has been reliable, because all feeders have met the standards set by the SPLN, IEEE, and WCS, especially the WT 05 feeder meets the standard.
