Abstract

Ormu Village, located in Jayapura Regency, Papua, faces limited access to electricity due to its remote and challenging geographical conditions. This study aims to design an optimal hybrid renewable energy microgrid system combining solar and micro-hydro power to provide an efficient and sustainable electricity supply. The Hybrid Optimization Model for Electric Renewables (HOMER) was used to model and compare various energy generation technologies. The simulation results show that the micro-hydro power plant (PLTMH) supplies approximately 317.680 kWh/year (83,1%), while the solar power plant (PLTS) contributes around 64.713 kWh/year (16,9%). These systems are capable of generating electricity continuously throughout the year. In terms of investment feasibility, the Net Present Value (NPV) method indicates that PLTMH has a positive NPV, making it financially viable. The Profitability Index (PI) for PLTMH is greater than (>) 1, which also supports the investment decision. Furthermore, the Discounted Payback Period shows that the initial investment for PLTMH can be recovered within 12,05 years. On the other hand, the PLTS system has a negative NPV, indicating it is not economically feasible. The PI is less than (<) 1, and based on the Discounted Payback Period method, the investment cannot be recovered even after 25 years.
