Leveraging Performance Evaluation through Special Maintenance of Photo Voltaic Power Plant in Nusa Tenggara Region to Achieve Photovoltaic Reliability Excellence

PLN committed to achieve renewable energy mixture up to 23% in 2025 that consists of 8.0% water, 7.3% geothermal, 1.8% wind & solar, and 5.8% biomass/waste/co-firing as listed in the 2021-2030 Electricity Procurement Plan (RUPTL) of PLN, as the greenest or environmentally friendly RUPTL with the portion of renewable energy power plants set to 51.6%. To achieve such ambitious target, PLN has developed several Communal Photovoltaic Power Plants either Off-Grid System, On-Grid System and also Hybrid System, scattered across Indonesia especially in the small and remote island in the eastern region of Indonesia. This paper aims to perform novel performance evaluation through specific Mapping and Scanning of main component of Photovoltaic (PV) Power Plant. The scope of performance evaluation focused on main component of PV Power Plant like PV panel, and inverter only. This paper includes lesson-learned and success story of PV Power Plant operation and maintenance.
