On June 22, Unit 9 of the Phase IV expansion project at the Zheneng Jiaxing Power Plant—designed by China Energy Engineering Group Zhejiang Institute and built by Zhejiang Thermal Power Construction Co.—successfully completed a 168-hour full-load trial and has officially entered commercial operation. With this addition, the plant’s total installed capacity has reached 6.3 million kilowatts, further bolstering East China Region’s energy security ahead of the summer peak demand season.

Located in Pinghu, Zhejiang Province, the Phase IV project is a major infrastructure undertaking under the province’s 14th Five-Year Plan. It is also part of Zhejiang’s “Green, Secure and Stable Energy Supply” initiative and the province’s “Thousand Projects, Trillion-Yuan Investment” program aimed at driving effective investment. The project includes two ultra-supercritical, secondary-reheat coal-fired units—Units 9 and 10. The newly commissioned Unit 9, with a capacity of 1 million kilowatts, features one of the most efficient coal consumption rates among domestic units of its class. It is equipped with state-of-the-art ultra-low emissions systems for dust removal, desulfurization, and denitrification. The unit is expected to generate 5 billion kilowatt-hours of electricity annually—enough to power approximately 2 million households for a year.

Jiaxing Power Plant now operates nine generating units, making it the largest thermal power facility in East China Region. The current configuration includes two 330,000-kilowatt units from Phase I, four 660,000-kilowatt units from Phase II, two 1-million-kilowatt units from Phase III, and one 1-million-kilowatt ultra-supercritical secondary-reheat unit from Phase IV. Since its commissioning in 1994, the Jiaxing Power Plant has generated more than 500 billion kilowatt-hours of electricity—equivalent to over a decade’s worth of consumption for a medium-sized city.
