CATL, Sungrow and CRRC Zhuzhou lead Chinese energy storage rankings 

China’s top energy storage companies in 2024 have been named by the China Energy Storage Alliance (CNESA), which unveiled its annual rankings recently. The rankings, based on shipment volumes and installed capacity, offer a snapshot of the evolving competitive landscape in China’s energy storage sector and its expanding global footprint. 

CATL retained its dominance as the leading energy storage technology provider by global battery shipments, excluding backup power applications. Other top performers in this category included EVE, Hithium, BYD, REPT BATTERO, and CALB. CNESA defines energy storage technology providers as companies that independently produce and supply core technologies such as battery cells and physical storage systems.

System integration, which encompasses the delivery of full energy storage systems—including batteries, PCS, EMS, and supporting infrastructure—was another fiercely competitive category. CRRC Zhuzhou Institute topped the domestic rankings in both installed capacity and shipments of grid-connected systems. Sungrow followed closely and claimed the top position globally by shipment volume. Other notable integrators included Envision Energy, HyperStrong, XYZ Storage, SCETL, ROBESTEC, and Goldwind
