Unit 7 of the Tianwan nuclear power plant in Jiangsu Province connected to the grid on October 8, 2026, according to China National Nuclear Corporation. The unit uses third generation nuclear technology, has a 60 year design life, and is expected to generate nearly 10 billion kWh per year. It is part of a four unit China-Russia cooperation project that started construction in May 2021. Once all eight Tianwan units are operating, the site will have over 9 GW of installed capacity and produce more than 70 billion kWh annually. The operator says this would cut CO2 emissions by 57.4 million tons per year. Unit 8 is scheduled to enter commercial operation in 2027. For carbon markets and grid watchers, this adds steady low-carbon baseload in East China, though the actual emission reduction depends on what generation it displaces.
