EVE Energy has set a new industry milestone, with the world’s first 400MWh energy storage project using 628Ah ultra-large cells successfully connected to the grid at Phase II of the Ruite New Energy project in Lingshou, Hebei, China.
Amid the global energy transformation, energy storage systems are rapidly advancing in scale and market readiness. Cells exceeding 600Ah are now key to improving energy density, reducing lifecycle costs and enhancing safety and reliability.
The Lingshou 200MW/400MWh standalone energy storage project, jointly developed by EVE Energy and State Grid Power Technology, represents the world’s first large-scale application of 628Ah cells in a 100MWh-level facility, setting a new benchmark for the industry.
EVE delivered and grid-connected 80 Mr.Giant energy storage systems and 40 integrated converter cabins within just one week, demonstrating exceptional project execution capabilities. From quality control and engineering coordination to system commissioning and operational support, the company has proven the maturity and feasibility of big-batteries technology.
As the world’s first operational 100MWh-scale large-cell storage project, it provides critical practical experience for large-scale applications, significantly improves regional grid peak-shaving and frequency regulation, increases power supply reliability and renewable energy integration and supports Hebei Province’s energy structure optimization and carbon goals.
