Abstract

The calculation of the reliability at the PLTU Anggrek 2×25 MW Gorontalo obtained a LOLP value of 61.5 days/year. This value was still above the standard
reliability value of PLN, this was due to the occurrence of PO (Planned Outage) and MO (Maintenance Outage) in unit 2 in June-July 2021, namely in the
form of the first-year inspection in July. The FOR (Force Outage Rate) value was calculated based on the disturbance data from the generator in 2021. The
daily load value was obtained from the load forecast value in January-July using FIS (Fuzzy Inference System) Mamdani type using the Matlab Toolbox. The
error value in the proposed load forecast was 8%. The rules that had been compiled were used to predict expenses in August-December 2021. From the results
of forecasting From the results of forecasting expenses, it was found that the trend of expenses was increasing every month.
