Work on the Upper Tatay pumped-storage hydropower project in the hilly southwestern province of Koh Kong started on April 10, Xinhua reported, describing it as a future “green power bank” for Cambodia’s national grid. It said the project was a “large-scale rechargeable battery system” with an installed capacity of one gigawatt.

It also came as Cambodia, like other developing countries, fretted over the price and availability of imported fuel due to Middle East bottlenecks and a lack of domestic refining, Menon said. “The fuel crisis has hit Cambodia very hard,” he said.

State-owned China National Heavy Machinery Corporation is developing the Upper Tatay project. Xinhua said Chinese-built power plants had helped raise Cambodia’s electricity access rate – the percentage of the population with reliable access to electricity in their home – from roughly 50 per cent to about 96 per cent since 2010. It said the station would provide for “stable integration” of intermittent solar and wind energy. AdvertisementSelect VoiceSelect Speed0.8x0.9x1.0x1.1x1.2x1.5x1.75x00:0000:001.00x
