Marine-Based Renewable Energy Solution for 3T Areas in Indonesia: Integrating Diesel Hybridization with Floating PV Power Plant

To fulfill Paris Agreement commitments, an effective strategy involves advancing renewable energy (RE) adoption, especially in 3T (underdeveloped, frontier, outermost) regions dependent on diesel power. Nain Island, a 3T area, relies on a 200kW diesel plant operating 7 hours/day for 1004 households. This research aims to extend electricity services to 24 hours/day without extra fuel by integrating a 300 kWp photovoltaic (PV) plant with the existing diesel setup. Determining PV capacity considers parameters like diesel capacity, load profile, households, and outage rates. Implementing the PV plant encounters challenges due to limited land and hilly terrain. The solution proposes floating PV plant technology, globally successful and applicable in Indonesia. Placement on the northern coastal area of Nain Island, near the existing diesel plant, addresses land limitations. Detailed design considerations, including wave patterns, wind speed, and bathymetry, are crucial for successful implementation. Upon deployment, the system promises a substantial increase in electricity service without additional fuel consumption, leading to a reduction of 389 tons/year in CO2 emissions. This innovative approach aligns with global sustainability goals, showcasing the potential for renewable energy integration in remote areas and underscoring the significance of environmentally friendly solutions.
