In the heart of Indonesia, Bunaken Island is making strides towards a more sustainable energy future, thanks to innovative research led by Muhammad Ridho Rohman Zuhri from Universitas Indonesia. The island, which has long relied on a hybrid power system combining solar photovoltaic (PV) panels and diesel generators, is now optimizing its energy mix to reduce costs and emissions. This development could have significant implications for the energy sector, particularly in remote and isolated regions.
The study, published in the *International Journal of Electrical, Power and Energy Systems*, focuses on improving the efficiency of Bunaken Island’s hybrid power system. High reliance on diesel generators has been a persistent issue, leading to increased fuel consumption and carbon dioxide (CO₂) emissions, especially during periods of low solar output. “The goal was to optimize the system to improve efficiency, reduce fuel consumption, decrease emissions, and minimize energy costs,” explained Zuhri.
Using HOMER software, the research team simulated the system, considering load profiles, solar radiation, temperature, and various system parameters. The optimized design yielded impressive results. The levelized cost of energy (LCOE) was reduced from IDR 2,775/kWh to IDR 2,436/kWh, a significant drop that highlights the cost-effectiveness of the optimized system. Additionally, CO₂ emissions were cut from 511.9 tons/year to 423.5 tons/year, and diesel consumption decreased from 195,741 liters/year to 161,921 liters/year.
These findings are not just about numbers; they represent a practical optimization model for remote island energy systems. The model integrates economic, environmental, and technical performance, promoting dedieselization by reducing reliance on diesel fuel. “This model provides a replicable framework for other isolated regions facing similar energy challenges,” Zuhri noted. “It supports the national transition toward cleaner and more sustainable energy solutions.”
The implications for the energy sector are substantial. As the world moves towards renewable energy, the need for efficient and cost-effective hybrid systems becomes increasingly important. This research offers a blueprint for other regions to follow, demonstrating that sustainability and cost savings can go hand in hand.
Moreover, the study’s focus on reducing diesel consumption is particularly relevant in the current geopolitical climate, where energy security and independence are paramount. By decreasing reliance on diesel, regions can mitigate the impact of volatile fuel prices and reduce their carbon footprint.
The research by Zuhri and his team is a testament to the power of innovation in driving sustainable energy solutions. As the world grapples with the challenges of climate change and energy security, such studies provide valuable insights and practical solutions. The optimized hybrid power system on Bunaken Island is not just a local success story; it is a beacon of hope for a more sustainable energy future.
