Indonesia has opened a $108m (£88m) floating solar plant in a significant renewable energy milestone for the country. 

The project was developed by PLN Nusantara Power and the renewable energy company Masdar from the United Arab Emirates (UAE). 

The plant was built on Cirata reservoir, 108km (67 miles) south-east of the capital Jakarta. It is the third-largest floating solar plant in the world and could be expanded up to 1,000MWp, PLN chief executive Darmawan Prasodjo said.

The 13 arrays installed so far only occupy 4 per cent of the reservoir’s surface.

“Today is a historical day, because our big dream to build a renewable energy plant on a big scale is finally achieved,” President Joko Widodo said. “We managed to build the largest floating solar farm in South-east Asia, and the third biggest in the world.”

The project includes the installation of of 340,000 solar panel units across 250 hectares, which are expected to generate 245GWh of electricity...
