Abstract

The high operational costs of Diesel Power Plants (DPP) in remote areas have pushed the Indonesian government to implement a dedieselization program. This initiative aims to replace or integrate existing DPPs with renewable energy (RE) sources, a strategy being implemented in isolated areas like Nusa Penida Island. Currently, DPPs primarily supply the island’s electricity, with only a small contribution from solar PV. As electricity demand rises, especially to support the growing tourism sector, an additional DPP has been rented to prevent blackouts. However, this has led to an increase in the Levelized Cost of Energy (LCOE) due to high fuel consumption. Given these challenges, this research aims to find the most optimal hybrid system composition using RE as a long-term solution for reliable power supply on Nusa Penida Island. Simulation results from Homer Pro and PVsyst software show that the most optimal system includes a 9.8 MW DPP, an 18.6 MWp PV, and a 36.4 MWh battery. This configuration has a Net Present Cost (NPC) of $195,466,300 and an LCOE of $0.186/kWh, representing a significant reduction in electricity production costs. Furthermore, the hybrid PV system is projected to generate 31.8 GWh of energy with a performance ratio of 0.8.
