On April 29, Unit 1 of the world’s first 630°C ultra-supercritical double-reheat national demonstration power project was connected to the grid in a single go.

The project, built by China Datang Corporation Limited in Yuncheng County of Shandong Province, can now generate power to the grid and is under preparation for the upcoming 168-hour full-load trial operation and subsequent commercial operation.
The highlight of the power project is that it raises the steam temperature at the turbine inlet to 630°C and pushes the thermal efficiency of electricity generation above 50 percent.
Built with domestically developed materials and technologies, the project ends China’s long-standing reliance on imported materials for components operating under high temperatures and high pressure. It not only promotes the formation of a complete, independent industrial system spanning material R&D, equipment manufacturing and engineering application, but also achieves dual breakthroughs — the independence of core technologies and the upgrading of equipment. Having been successfully connected to the grid, the project lays a solid foundation for the future research and application of more advanced ultra-supercritical power generation technologies.
Compared with conventional 1,000-megawatt generating units, the new power project will, upon commissioning, save 208,000 tons of standard coal and cut 540,000 tons of carbon dioxide emissions annually. It combines efficient power generation with environmental protection, providing support and a model for China’s energy structure transformation and the attainment of its carbon peaking and neutrality goals.
