To improve national grid stability, the Department of Energy (DOE) has issued a new directive requiring all large-scale renewable energy projects to integrate energy storage systems (ESS).

Jinko ESS, a global leading energy storage solution provider and a subsidiary of Jinko Solar Co., Ltd., recently announced the successful completion of a large-scale fire test for SunTera 5MWh Liquid-Cooling Energy Storage System. Conducted at a specialized testing facility in Suzhou City, Anhui Province, the test followed the CSA C800 standard and the November 2025 draft of UL 9540A and was witnessed on-site by CSA Group representatives and North American fire protection engineers.

In January 2026, China’s user-side new energy storage market recorded a year-on-year decline of more than 50% in newly added capacity. The pace of project filings slowed while quality improved, and market deployment shifted toward larger single projects and more capital-intensive investments.

China’s new-type energy storage market witnessed a strong start in January 2026. Newly commissioned capacity in January increased by over 60% year-on-year, while the market’s underlying structure showed notable adjustments compared with the same period last year.

Recently, China has achieved a major breakthrough in the research and development of compressed air energy storage(CAES) technology . Developed jointly by the Institute of Engineering Thermophysics, Chinese Academy of Sciences(IET, CAS) and ZHONG-CHU-GUO-NENG(BEIJING)TECHNOLOGY CO.,LTD., the world’s first CAES compressor with the largest single unit power has successfully passed the third-party testing accredited by CNAS. According to the test results, the compressor achieved maximum discharge pressure of 10.1MPa, a maximum power output of 101MW and an operating range of 38.7% to 118.4% under variable conditions and an efficiency of 88.1% at maximum discharge pressure, reaching an internationally leading level.

During the 14th Five-Year Plan period, China’s energy storage technology mix witnessed noticeable changes where pumped hydro storage accounted for less than 40% for the first time while the new-type energy storage represented by lithium batteries saw explosive growth.

On January 8, 2026, a 500MWh standalone Battery Energy Storage System(BESS) project located at Maritsa East 3 in Bulgaria was officially commissioned. The project was the jointly developed by BYD Energy Storage and ContourGlobal under their strategic collaboration which is one of the largest standalone energy storage projects in East Europe.

Recently, Tianneng Group signed a strategic agreement with NASDAQ-listed company VCIG Group. The two parties will build a 1GWh AIDC solar energy storage power station in Malacca, Malaysia. The project aims to address the high-energy-consumption challenge of AIDC and will be developed under an “EPC+F” model.
