Abstract

A power generation system must be able to meet consumer needs and be reliable in its distribution, for that the distribution of electrical power must be good in terms of quality and continuity. In order to determine the level of reliability of a power generation system, it is necessary to evaluate the level of reliability of the power generation system. In this study, an evaluation of the level of reliability of power plants on Sumbawa Island for the period of 2025 was carried out. The research was conducted using the method of analyzing the calculation of LOLP (Loss of Load Probability) and EENS (Expected Energy Not Served). The data required in the study are the total number of generating units and the FOR (Forced Outage Rate) value as well as daily load data and peak load of the Sumbawa Island electricity system. This study aims to obtain the reliability value of the generating system on Sumbawa Island. The results of this research analysis resulted in an output LOLP value of 5.6 days / year and EENS of 46801310.7 kWh / year or 0.188% / year. From the LOLP standard of 1 day / year and EENS of 0.002% / year, the LOLP and EENS values of the Sumbawa Island generation system show that the system condition is in the unreliable category.
