On November 5, the No. 6 unit of the Puqi Phase III 2×1000 MW ultra-supercritical coal-fired power project in Hubei Province successfully completed a 168-hour full-load trial operation, marking the official commissioning of China’s first 1-million-kilowatt “Six-in-One Control” power project.

This project, constructed by China Energy Engineering Group Co., Ltd., is located in Chibi City, Xianning, and is a key project of Hubei’s 14th Five-Year Plan. It consists two 1,000 MW ultra-supercritical double-reheat coal-fired generating units, equipped with advanced flue gas desulfurization and denitrification systems.
The project introduces China’s first “Six-in-One Control” design concept, which integrates centralized control of turbines, boilers, electrical systems, grids, and auxiliary equipment. It achieves unified monitoring and scheduling of multiple units by seamlessly integrating with the first and second phases. This innovation significantly enhances operational efficiency and management performance while reducing production costs.
All control systems use domestically developed distributed control system (DCS) products based on Chinese-made chips and operating systems, realizing integrated control of main and auxiliary systems and breaking foreign technological monopolies.
As the core project of Chibi’s integrated “wind–solar–thermal–storage” energy system, the plant will generate 9 billion kWh of electricity annually once fully operational. It will help meet Hubei’s growing power demand, ease grid supply pressure, enhance power regulation capacity, facilitate the consumption of new energy in southeastern Hubei, and contribute to building a clean, low-carbon, safe, and efficient modern energy system in the province.
