The Zhangzhou Nuclear Power Plant in east China's Fujian Province – the world's largest base employing the Hualong One reactor – connected its Unit 2 to the grid for the first time on November 22, marking a major step forward in the mass construction of China's domestically developed third-generation reactor.

The plant is designed to have six Hualong One nuclear power units. Each unit can generate more than 10 billion kilowatt-hours of electricity per year, enough to meet the annual production and domestic electricity demands of 1 million people in a moderately developed country. This is equivalent to reducing standard coal consumption by 3.12 million tonnes annually and cutting carbon dioxide emissions by 8.16 million tonnes per year.
