JAKARTA - Indonesian President Joko Widodo on Thursday inaugurated Southeast Asia's largest floating solar plant, which occupies an area of 250 hectares above the Cirata Reservoir in West Java Province.

"Today is a historical day because our big dream of building a large-scale renewable energy plant is finally achieved. We managed to build the largest floating solar plant in Southeast Asia, and the third biggest in the world," Widodo said at the on-grid ceremony.

Constructed by China's PowerChina Huadong Engineering Corporation Ltd., the power plant was a collaboration project between Indonesia's state electricity corporation PLN and the United Arab Emirates energy company Masdar, with an investment of $145 million.

Spread over the reservoir surface with more than 340,000 solar panels, the 192-megawatt-peak capacity power plant can produce 300 million kilowatt hours of energy annually, complementing the hydropower generation available in the reservoir.

Widodo also encouraged using renewable energy potential to support the country's efforts to reduce carbon emissions and pursue the target of net zero emissions by 2060.
