In the heart of East Kalimantan, a new capital city is rising from the ground, poised to reshape Indonesia’s future. Ibu Kota Nusantara (IKN), as it’s known, is more than just a new administrative center; it’s a bold vision for sustainable urban development. And at the core of this vision lies a powerful, yet often overlooked, energy source: the sun.
A recent study published in Mekanika, the Indonesian Journal of Mechanical Engineering, delves into the potential of solar power in IKN’s government buildings. Led by Mohd Afzanizam Mohd Rosli from the Department of Mechanical Engineering at Universiti Teknikal Malaysia Melaka, the research uses a sophisticated tool called HOMER (Hybrid Optimization Model for Electric Renewables) to evaluate the feasibility of solar energy systems in the new capital.
The study’s findings are promising. According to Rosli, “The proposed solar energy system can generate approximately 828,980 kWh annually, which is more than enough to meet the energy demands of government buildings in IKN.” This is a significant step forward, considering the region’s abundant solar resources and the government’s commitment to innovative, sustainable development.
The HOMER model used in the study integrates solar panels, batteries, and inverters with the on-grid electrical system. This configuration is tailored to meet the specific energy requirements of government buildings, ensuring a reliable and efficient power supply. The estimated investment cost for this system is around IDR 20,581,290,000, with a production cost of IDR 1,407.11 per kWh. The net payback period is approximately seven years, making it an economically viable option in the long run.
But the implications of this research go beyond just numbers and graphs. It’s about shaping a new energy landscape, one that prioritizes sustainability and innovation. As IKN continues to take shape, the success of solar energy systems in its government buildings could pave the way for wider adoption across the city and beyond. This could lead to a significant reduction in carbon emissions, decreased reliance on fossil fuels, and a more resilient energy infrastructure.
For the energy sector, this research opens up new opportunities. It highlights the potential of solar power in emerging markets and the importance of tailored, optimized solutions. It also underscores the need for continued investment in renewable energy technologies and infrastructure. As Rosli puts it, “Solar energy systems are well-positioned to thrive in IKN’s emerging business environment, and this could set a precedent for other cities in the region.”
The study published in Mekanika, which translates to the Journal of Mechanics, serves as a testament to the power of innovation and the potential of solar energy. As IKN continues to grow and evolve, so too will its energy needs. And with research like this, the future looks bright—literally and figuratively. The energy sector would do well to take note, for the sun is rising on a new era of sustainable development.
