Abstract: The purpose of this paper is to conduct a feasibility study of hybrid power system based on renewable energy resources for Miangas island, which is located on the border between Indonesia and the Philippines. It is the outermost island that situated in the North part of Sulawesi mainland which became the front porch of Indonesian territory. The prospect of PV-wind-diesel-battery hybrid system as an alternative power supply for Miangas island has been analyzed using HOMER (Hybrid Optimization Model for Electric Renewable). The predicted monthly average daily radiation in Miangas island is 5.52 kWh/m². The wind speed varies seasonally from 3.1 m/s to 5.3 m/s. The hybrid system analysis has showed that the electricity is generated in a year is 240,068 kWh in which electricity energy sharing consist of PV, wind, diesel are 77%, 0.5% and 22.5% respectively. In addition, the simulation results for the proposed hybrid system in Miangas island community find the value of cost of energy (COE) as 0.3178 USD/kWh, Net Present Cost (NPC) as 986,356 USD and operating cost as 52,887 USD.
