Achieving net-zero emissions by 2060 is a crucial target for all countries that signed the Paris Agreement in 2015, which mandates the phase-out of fossil fuel-based power plants. This study focuses on optimizing a hybrid power plant system in Nusa Penida, an isolated island in Indonesia with high potential for renewable energy utilization. With its abundant renewable energy resources and significant tourism appeal, Nusa Penida presents an ideal location for a sustainable energy project. The study evaluates a renewable energy system configuration comprising PV solar panels, wind turbines, and Oscillating Water Column (OWC)-based wave energy technology, combined with battery energy storage. Simulation results indicate that the most cost-efficient configuration consists of 65,258 kW of PV solar panels, 31,350 kW of wind turbines, 2,687 kW of wave power generation using the OWC system, and 128,519 kWh of battery storage capacity. This optimal setup achieves the lowest Levelized Cost of Energy (LCOE) at $0.191/kWh, compared to the current system’s estimated $0.485/kWh, demonstrating a significant cost reduction. Moreover, the proposed configuration integrates multiple renewable energy sources, ensuring economic feasibility, enhanced sustainability, and the potential for new renewable energy sources to serve as firm capacity in meeting system demand. The implementation of this scheme requires an initial investment of $170 million with an annual operational cost of $2.83 million. Based on these findings, the proposed hybrid renewable energy system represents the most economically viable solution for meeting Nusa Penida’s energy needs while supporting Indonesia’s commitment to a sustainable energy transition.
