Abstract

Reliable electricity access in remote archipelagic regions is a fundamental challenge to increasing the electrification ratio in Indonesia. This study evaluates the performance and reliability of a 760 kWp off-grid Photovoltaic (PV) Power Plant on Palue Island, which faces operational failure due to severe load growth. The research methodology integrates three approaches: Monte Carlo simulation to project system reliability from historical data, a simulation tool to validate the PV array’s technical performance, and an optimization platform for the techno-economic analysis of a hybrid PV-BESS-Diesel system. The analysis confirms the existing system’s inadequacy, with a projected Loss of Load Probability (LoLP) of 84.81% by 2025. To achieve 100% reliability, the optimal solution involves retaining the 760 kWp PV array, expanding the Battery Energy Storage System (BESS) to 2,800 kWh, and adding a 190-kW diesel generator for backup. This optimized architecture successfully meets all loads with a high renewable fraction of 99.5% and a competitive Levelized Cost of Energy (LCOE) of $0.282/kWh. This research provides a robust, data-driven retrofit framework for failing renewable energy systems, offering a replicable model for enhancing electrification in other remote regions.
