An energy storage facility in China<\/strong> that combines supercapacitors<\/strong> and batteries<\/strong> has begun operations. The 100 MW hybrid facility<\/strong> will serve to regulate the grid frequency<\/strong>.<\/p>\n\n\n\n

A 100 MW hybrid frequency regulation facility<\/strong> has entered service in China’s northern Shanxi province<\/strong>. Billed as the world’s largest supercapacitor-based facility<\/strong>, the project combines a 58 MW\/30-second supercapacitor array<\/strong> with a 42 MW\/42 MWh lithium-ion battery system<\/strong>. The facility, constructed on an area of approximately 16,800 square meters<\/strong>, was brought online with an investment of 670 million yuan ($94 million)<\/strong>.<\/p>\n\n\n\n

Located in a village in the city of Xinzhou, the facility is situated in a region known for its abundant sunlight and water resources. These features provide ideal conditions for large-scale renewable energy and storage solutions.<\/p>\n\n\n\n

Supercapacitors Offer Fast Response Times and Long Lifespans<\/strong><\/h2>\n\n\n\n

The system is controlled by an energy management system<\/strong> that dynamically distributes tasks between the supercapacitors<\/strong> and batteries<\/strong>. The supercapacitors<\/strong> handle changes on a millisecond<\/strong> scale, while regulation tasks on a minute<\/strong> scale are performed by the batteries<\/strong>.<\/p>\n\n\n\n

Supercapacitors<\/strong> provide ultra-fast response times, such as 0.001 seconds<\/strong>, and significantly outperform lithium-ion batteries<\/strong> in extreme cold, retaining over 85% of their capacity at -40\u00b0C<\/strong>. This extends the lifespan of the batteries, with the goal of reducing life-cycle costs by 30%<\/strong>.<\/p>\n\n\n\n

The facility’s operational targets include maintaining the grid frequency<\/strong> within a \u00b10.02 Hz<\/strong> limit and responding to system changes within one second<\/strong>. Thanks to this high-speed response capability, 1.6 GW of variable renewable energy<\/strong>\u2014approximately 20 times the plant’s instantaneous power\u2014can be integrated into the grid.<\/p>\n\n\n\n

The plant is expected to generate over 120 million yuan ($16.5 million)<\/strong> in annual revenue, contribute around 12 million yuan<\/strong> in taxes, and achieve a return on investment within approximately 7 years<\/strong>. It was also noted that the project created over 500 jobs<\/strong>.<\/p>\n\n\n\n

In a planned second phase<\/strong>, the capacity is targeted to be increased to 200 MW<\/strong>. The hybrid model is also planned for use in resource-rich regions like Inner Mongolia<\/strong> and Xinjiang<\/strong>, where China is rapidly expanding its large-scale renewable energy infrastructure.<\/p>\n\n\n\n
