In the heart of Indonesia, a novel approach to renewable energy is making waves, quite literally. Researchers, led by Evely Tirza from Universitas Katolik Parahyangan, are exploring the feasibility of integrating floating solar panels with the existing hydropower system at the Matenggeng Dam. This hybrid power plant concept could potentially stabilize electricity production, which is currently subject to seasonal fluctuations.
The Matenggeng Dam, a multipurpose dam designed for irrigation, flood control, and hydropower, has a capacity of 11.74 MWac at optimal water levels. However, during the dry season, this output can drop to 5.74 MWac. To mitigate this variability, Tirza and her team propose a hybrid system that combines hydropower with floating solar photovoltaic (FPV) panels.
“By harnessing the power of the sun, we can compensate for the decrease in hydropower production during low water periods,” Tirza explains. The team found that, adhering to Indonesian regulations which permit only 20% of the water surface area to be used, an optimum area of 295.7 hectares can accommodate FPV installation. The results were promising, with the solar power plant generating a stable 1,200 MWh per month, amounting to 14 GWh annually.
This research, published in the Journal of Civil Engineering Communications, highlights the potential of hybrid power plants to enhance energy stability and efficiency. The commercial implications for the energy sector are significant. Hybrid systems can provide a more consistent power supply, reducing reliance on non-renewable energy sources and mitigating the impacts of seasonal variability.
The integration of FPV systems with existing hydropower infrastructure presents a unique opportunity for the energy sector. As Tirza notes, “This approach not only optimizes the use of available resources but also contributes to the broader goal of transitioning to renewable energy.” The success of this project could pave the way for similar initiatives worldwide, shaping the future of sustainable energy production.
In an era where renewable energy is increasingly vital, the Matenggeng Dam project stands as a testament to innovative engineering and strategic planning. As the world grapples with climate change and energy security, such hybrid systems could play a crucial role in meeting global energy demands sustainably.
