The Cirata Floating Photovoltaics (FPV) Project, Southeast Asia’s largest floating solar facility, has officially begun operations, marking a significant milestone in Indonesia’s renewable energy transition. Developed by PowerChina in partnership with Indonesia’s state-owned electricity company PLN and the UAE’s Masdar, the 192-megawatt project is Indonesia’s first large-scale floating solar plant. It was successfully connected to the national grid in November 2023.
Constructed on the Cirata Reservoir, the project overcame substantial engineering challenges, including complex underwater terrain and high wind speeds. To secure the floating arrays, PowerChina implemented a specialized anchoring system using metal shear keys and concrete counterweights. Extensive wind tunnel testing and computational modeling were also conducted to optimize panel arrangement and ensure structural stability.
Speaking at the grid-connection ceremony, Indonesian President Joko Widodo hailed the project as a crucial step toward the nation’s clean energy ambitions and net-zero emissions targets. The Cirata plant contributes significantly to Indonesia’s renewable energy supply, generating 300,000 MWh annually—enough to power 50,000 homes. It also plays a key role in reducing reliance on coal, cutting coal consumption by 117,000 tons and lowering carbon emissions.
The success of the Cirata project highlights the importance of global collaboration in advancing sustainable energy initiatives. PowerChina reaffirmed its commitment to supporting global renewable energy development through open and mutually beneficial international partnerships.
