On October 24, the CNNC Tianwan 2 GW tidal flat PV demonstration project in Lianyungang, Jiangsu province, reached a major milestone, with its cumulative grid-connected capacity exceeding 1 GW. This achievement marks significant construction progress, as the project has surpassed half of its planned grid-connected capacity and laid a solid foundation for full-capacity grid connection.

The onshore substation has been completed, while the supporting energy storage facility has achieved full-capacity grid connection and began operations in June 2024. Once fully operational, the project is expected to generate more than 2.2 billion kWh of electricity annually. Over its 25-year operating life, it is expected to save an average of 681,200 metric tons of standard coal and reduce carbon dioxide emissions by 1.77 million tons each year. It will provide a sustained supply of clean energy to support local economic and social development.

The Tianwan project is the largest offshore PV project in China and the world's first demonstration project featuring a multi-energy complementary system integrating nuclear power, thermal power, solar power, and energy storage.
