The last generating unit at China's 5,850-MW Huaneng Nuozhadu hydropower plant is now in operation, developers of the plant have reported.
Located in China's Yunnan Province on the lower reaches of the Lancang River, the plant is now the fourth-largest project in China.
The Huaneng Group said the complex's powerhouse includes nine 650 MW generating units -- the first of which was put into operation in September 2012.
The project's vertical core-wall rockfill dam is the tallest in China and third in the world at more than 261 meters high, according to the developer, while the spillway is Asia's largest in size and No. 1 in the world in terms of flood discharge and flow velocity.
The plant is part of China's initiative of making the Yunnan Province a power exporter for surrounding areas and is expected to save the equivalent of 9.56 million tons of coal annually.
