On October 31, China’s first independently developed and patented magnetic levitation flywheel energy storage system—the largest of its kind globally—was successfully installed at CHN Energy’s Shandong Company. This installation marks the entry of magnetic levitation flywheel storage project of Shandong Company into the joint commissioning and testing phase.

Magnetic levitation flywheel energy storage, known for its high efficiency and eco-friendliness, offers advantages such as fast response times, high energy density and long lifespan, presenting significant potential for use in power systems.

The Shandong company's flywheel energy storage project, designated as a demonstration project by the National Energy Administration, aims to explore the potential of flywheel storage technology in secondary frequency regulation for Automatic Generation Control (AGC). The system features an array of three flywheels, each with a capacity of 4 MW/1 MWh, coupled with two 330 MW thermal power units at the Penglai site. The flywheel system charges and discharges through the plant’s high-voltage auxiliary power section, dynamically adjusting real-time load to modify the generator's grid-connected power output, thereby optimizing the power generation capabilities of the thermal units.

The recently installed flywheel is one of the core components of the project, developed with independent intellectual property rights. Its design, manufacturing and installation all meet advanced international standards, marking the first independent application of flywheel technology in AGC secondary frequency regulation in China. This installation represents a significant breakthrough in domestic flywheel energy storage technology. By the end of October, the Shandong project had achieved 10 technical innovations, received acceptance for six invention patents, and published four research papers, two of which appeared in core journals.
