EVE Energy has connected a 200 MW/400 MWh standalone energy storage system to the grid at Phase II of the Ruite New Energy Project in Lingshou, Hebei Province, China, marking the first large-scale deployment of 628 Ah ultra-large cells. This milestone demonstrates the company’s capability to advance high-capacity cell designs from research and development through mass production and full system integration.
The grid connection occurred on September 8 and represents the world’s first application of cells exceeding 600 Ah in a 100 MWh-class facility. By leveraging these larger cells, the project aims to improve energy density, lower lifecycle costs and enhance overall safety and reliability in utility-scale energy storage.
In a display of rapid project execution, EVE Energy delivered 80 prefabricated Mr. Giant energy storage modules and 40 integrated converter cabins within one week. The modules went through rigorous quality control checks, engineering coordination and system commissioning to ensure reliable operation upon energization.
Once operational, the storage system supports regional grid peak-shaving and frequency regulation, boosts power supply reliability and facilitates the integration of renewable generation in Hebei Province. The project also provides valuable practical experience for deploying ultra-large cells at scale and offers a model for future installations worldwide.
Building on this achievement, EVE Energy began its first overseas shipments of the Mr. Giant storage system on September 10, delivering units to customers in Australia and Europe. The solution’s modular design, high conversion efficiency, low acoustic emissions (≤65 dB) and four-plus hour discharge capability have garnered international interest in long-duration storage applications.
By completing both the first grid connection and the initial international deliveries of its 628 Ah cells, EVE Energy has validated the commercial readiness of its big-batteries technology. The company plans to continue expanding its technology-driven strategy and partner with global stakeholders to accelerate the green energy transition.
