The coastal area of Parangtritis Beach, Bantul Regency, Special Region of Yogyakarta, is experiencing growth in tourism facilities and livestock farming that demands a reliable electricity supply, while the reliability of the distribution network in coastal areas remains limited. This study aims to design a hybrid PV–wind power generation system to serve the combined load of a villa and a horse farm through simulation and optimisation using HOMER Energy software. Resource data were obtained from the NASA POWER database, with an annual average global horizontal irradiance (GHI) of 4.80 kWh/m²/day, an annual average wind speed of 4.24 m/s at 50 m height, and an average air temperature of 24.80 °C. The load profile was constructed hourly over 24 hours, yielding a daily energy demand of approximately 47–48 kWh/day. Initial capacity sizing was performed analytically for the PV array, the number of wind turbines, and the battery bank, and was subsequently verified through HOMER optimisation. The optimal configuration consists of a 12.0 kW PV system (400 Wp monocrystalline modules), five Aeolos-V1kW wind turbines (5.00 kW total), ten Fortress Power LFP-10 Lithium Ferro Phosphate batteries (96 kWh total), and a Schneider Conext XW+ 5548 converter. The system produces 20,185 kWh annually, with contributions of 78.8% from PV and 21.2% from wind, serving an AC primary load of 16,356 kWh/year with 2,539 kWh (12.6%) of excess electricity. Economically, the system yields a Net Present Cost (NPC) of IDR 330,581,600.00 and a Levelized Cost of Energy (COE) of IDR 1,053.13/kWh with an annual operating cost of IDR 7,730,206.00. These results indicate that the hybrid PV–wind system is technically feasible and economically competitive for autonomous energy supply in the southern coastal region of Java.
