Reliability is the success of performance in a system rather than an electric power system, in order to be able to give better results in a certain time span and in certain operations. In determining the level of reliability of a system, it must be carried out by performing calculations and analysis at the level of performance of the system reviewed, in a certain period after which it can compare it with the standards that have been determined. This final task was created with the aim of calculating the value of the SAIFI and SAIDI reliability indexes on PT. PLN (Persero) ULP Lambaro for 1 year from December 2020 to November 2021. From the results of calculation of SAIFI and SAIDI index values on refiners at PT. PLN (Persero) ULP Lambaro, the result of the calculation of SAIFI value of PT. PLN (Persero) ULP Lambaro which is 3,347 times / year categorized as less reliable because it exceeds the limit of the SPLN standard 59:1985, namely the SAIFI index value limit is 2,415 times/year, and the results of calculation of SAIDI value of PT. PLN (Persero) ULP Lambaro which is 0.524 hours / year categorized as reliable because the value of the SAIDI index does not exceed the SPLN standard of 59:1985 the saidi index value limit is 12,842 hours/year.} }
