PowerChina has completed construction of the 192 MW Cirata floating photovoltaic plant on the Cirata Reservoir in West Java, Indonesia. The facility, developed in partnership with PLN and Masdar, is the region’s largest floating solar power plant and began supplying power to the grid in November 2023. It generates 300,000 MWh annually—equivalent to the consumption of 50,000 homes—and currently contributes 25% of Indonesia’s renewable energy supply.
Custom-designed anchoring systems and structural innovations were applied to accommodate the reservoir’s challenging underwater terrain and weather conditions. President Joko Widodo welcomed the project’s contribution to Indonesia’s emissions goals, with projected savings of 117,000 tonnes of coal annually. The success of the plant is expected to drive similar floating solar initiatives across Southeast Asia.
