on March 25, 2026, the national energy storage yuci primary frequency modulation construction project successfully completed the various processes of grid connection and operation, and successfully connected to the power grid system and officially put into operation. This milestone event marks the company in the flywheel energy storage this new energy storage subdivision field to achieve zero breakthrough, engineering construction capacity and core technical strength has been further tempered and improved, for the company to expand the new energy storage business, deep-cultivated energy transformation track to build a solid foundation.
As the first flywheel energy storage demonstration project of Huadian Science and Technology, this project shoulders the dual mission of technology exploration and market expansion. The core construction content of the project is 8MW/800kWh magnetic levitation flywheel energy storage unit. As the current high-efficiency and clean mainstream technology of mechanical energy storage, flywheel energy storage has the remarkable characteristics of no chemical reaction and strong environmental adaptability. At the same time, it has the core advantages of fast response speed, high safety and reliability, long service life and low operation and maintenance cost. Its response speed can reach 10-50 milliseconds, and its charge and discharge cycle life exceeds one million times. It can accurately adapt to the core requirements of “fast frequency stabilization and bottom safety” of primary frequency modulation of power system, provide reliable support for grid frequency stability.

As the “first line of defense” of power system frequency stability, primary frequency modulation is directly related to the reliability and safety of power supply. After the project is put into operation, it will realize cooperative frequency regulation with the unit, effectively improve the frequency regulation capability and operation stability of Shanxi power grid, help the dynamic balance of regional power system, and escort the safe and stable operation of Shanxi power grid. At the same time, by participating in power grid auxiliary services, the project will obtain reasonable economic compensation for enterprises and realize the two-way improvement of social and economic benefits, which will not only contribute to the optimization and upgrading of regional energy structure, but also accumulate valuable experience for the market-oriented development of the company in the field of new energy storage.
next step, the energy construction branch will take this project as an opportunity to summarize the construction experience of flywheel energy storage project, continue to deepen the new energy storage field, focus on technological innovation and engineering quality improvement, continuously improve the core competitiveness, actively expand the energy storage business market, and help the company inject strong momentum into green transformation and high-quality development.
