on December 31, 2025, with the issuance of the grid connection instruction, the 1# and 2# flywheels of the fire storage joint frequency modulation project of the national energy huozhou power plant were successfully connected to the power grid system, marking the phased victory of the core flywheel unit provided by huachi kinetic energy (Beijing) technology co., ltd. in this major project. At the moment of leaving the old and welcoming the new, this achievement not only draws a successful conclusion to 2025, but also opens a new chapter in the construction of a new power system.

From early autumn to late winter, Huacheng has launched a race against time with all partners. On September 10, 2025, the project officially broke ground, on November 13, 2# unit energy storage medium voltage transformer grid-connected test, on December 4, 1, 2 flywheel ground shaft civil construction and installation, on December 5, 1 energy storage flywheel hoisting in place, on December 22, flywheel area comprehensive prefabricated cabin power was completed, on December 26, 2 energy storage flywheel installation was completed, Huozhou power plant fire storage joint frequency modulation project every node has taken a firm step, it has laid a solid foundation for the successful grid connection.

The successful grid connection of 1# and 2# flywheels means that the flywheel coupling unit has begun to formally undertake the task of frequency modulation, marking the successful completion of the construction task of the first phase of the project. But this is just the beginning. Huachi Kinetic Energy will continue to exert its technical advantages in the field of flywheel energy storage, provide all-round technical support for the Huozhou Power Plant project, and ensure the safe and stable operation of the system. At the same time, we will also use this project as a demonstration to promote the application of flywheel energy storage in more power scenarios.
