The Taishan Nuclear Power Plant (Chinese: 台山核电站; pinyin: Táishān Hédiànzhàn) is a nuclear power plant in Taishan, Guangdong province, China.^[3] The plant features two operational EPR reactors. The first unit, Taishan 1, entered commercial service in December 2018, but was shut down from July 2021 to August 2022 to investigate and fix issues with fuel rod cladding. The second unit, Taishan 2, entered commercial service in September 2019. Delays at other EPR construction sites in Finland and France meant that Taishan was the first nuclear power plant to have an operational EPR.

The project is owned by Guangdong Taishan Nuclear Power Joint Venture Company Limited (TNPC), which is 70% owned by China Guangdong Nuclear Power Group (CGNPC) and 30% by Électricité de France (EDF).

The plant's twin reactors each have a nameplate capacity of 1750 MWe. Its Arabelle generators are the largest single-piece electrical generators in the world, each weighing 495 tonnes and built by Dongfang Electric. Of the 3500 MWe gross delivered, around 180 MWe will be used by plant systems. Most of this is used to power the pumps that feed water into the steam generators. The pair of reactors can deliver 3320 MWe net for supply to the grid, making these the most powerful reactors in the world.^[4]
