Abstract: The Sutami Reservoir, located in Malang, East Java, Indonesia, has emerged as a pivotal site for demonstrating the integration of renewable energy systems. Historically designed for water management and flood control, this multifunctional infrastructure now leverages its water resources for sustainable power generation. This paper explores how the combination of hydropower and floating solar photovoltaic technologies can transform energy generation in Indonesia, aiding in the nation’s transition to a cleaner energy system. The research focuses on estimating carbon emission reductions and the broader environmental and operational benefits of such systems. The analysis reveals that these combined renewable technologies can mitigate approximately 532,327 tons of CO2 emissions annually. This equates to the carbon sequestration potential of 3,900 hectares of tropical forest. Hydropower contributes steady, reliable energy production, while floating solar PV enhances the system's overall efficiency by harnessing solar energy during peak daylight hours. This integration underscores the importance of innovative energy solutions to achieve Indonesia’s Nationally Determined Contributions (NDC) and advance its energy sustainability targets
