		abstract={A power plant is expected to operate reliably and efficiently. Thus, it is necessary to do an evaluation on several performance indexes that have been determined in the standards of Protap DKP-IP 2017 PT PLN (Persero). The object of this research is the Unit 2 of Wayang Windu Geothermal Power Plant to be analyzed on its performance in a 3-year interval during 2017-2019. The analyzed variables consist of Availability Factor (AF), Equivalent Availability Factor (EAF), Sudden Outage Factor (SOF), Equivalent Forced Outage Rate (EFOR), Capacity Factor (CF), Net Capacity Factor (NCF), and Net Output Factor (NOF). Based on the calculation results, the highest value of AF is 99,98% in 2018 and the lowest is 99.78% in 2017, the highest EAF value is 99.91% in 2018 followed by 99.63% in 2017 as the lowest, the best SOF value is 0.13% in 2017 and the worst value is 0.90% in 2018, the best EFOR value in 2018 is 0.02% and the worst value in 2019 is 0.15% , the highest CF value is 97.84% in 2018 and the 98.27% in 2019 as the lowest value, the highest NCF value is 98.41% in 2017 and the lowest value is 96.71% in 2019, the highest NOF value is 100.30% in 2018 followed by 99.73% in 2018 as the lowest. The longer the duration of derating or interference in the power plant, the worse the performance index will be. Overall, the highest performance index is 2018 followed by 2019 and 2017. Based on the performance index values, the unit 2 of Wayang Windu Geothermal Power Plant is able to exceed the annual operating targets in both 2017, 2018 and 2019.}
