World’s First 628Ah Large-Battery Storage Station Grid-Connected; EVE Energy Lands 10GWh Deal

On January 31, 2026, a landmark development unfolded in the energy storage sector as the world’s first grid-scale project utilizing 628Ah ultra-large battery cells was officially connected to the grid. The 400MWh Ruite New Energy Lingshou independent energy storage station is equipped with 80 units of EVE Energy’s Mr. Giant 5MWh DC storage systems, which integrate the 628Ah cells with a minimalist design, alongside 40 power conversion and step-up integrated cabins. This milestone represents a pivotal shift for EVE Energy’s large battery technology, moving it from forward-looking exploration to validated grid-scale deployment, thereby establishing a robust foundation for the energy storage industry’s high-quality advancement.

The grid connection ceremony witnessed the presence of senior leaders from both companies, including Zhou Ziguan, Chairman of Beijing Guowang Power Technology Co., Ltd., and Steven Chen, Senior Vice President of EVE Energy. During the event, a strategic cooperation agreement for future 10GWh large battery systems was formalized by Zheng Malin, Board Secretary and CFO of Beijing Guowang Technology, and Liu Hongguang, General Manager of Domestic Energy Storage Sales at EVE Energy. This signing elevates their partnership to a new strategic level, transitioning from isolated project execution to a deep, future-oriented alliance.

The successful commissioning of the Lingshou project underscores that the 628Ah large battery technology is fully capable of supporting the stable and efficient operation of grid-scale initiatives. This achievement is reinforced by EVE Energy’s complete industrial chain, built through its “Three Firsts” strategy—being the first to announce, mass-produce, and deploy at scale. With cumulative production of large battery cells surpassing 1 million units, the company has received dual validation for both manufacturing scalability and product maturity. The deployed system integrates EVE’s inherently safe cell technology and minimalist system design, incorporating core innovations such as stacking processes and high-toughness separators to significantly enhance intrinsic safety while optimizing the Levelized Cost of Storage (LCOS). These features precisely address the new power system’s critical demands for energy storage core equipment: high safety, high efficiency, and extended lifespan.

The 10GWh strategic agreement signals that the collaboration between EVE Energy and Guowang Technology has matured from single-project delivery to a long-term, symbiotic relationship focused on shared growth. At the ceremony, Zhou Ziguan, Chairman of Beijing Guowang Technology, noted that the success of the Lingshou project fully validates the significant advantages of large battery technology in improving plant economics and grid support capabilities. This substantial order serves as a powerful endorsement from a key player in energy infrastructure for EVE Energy’s technical roadmap, affirming that large batteries represent a definitive trajectory for the future evolution of the energy storage industry. Moving forward, both parties will accelerate technology deployment and scenario expansion, promote resource integration across the industrial chain, and build a collaborative ecosystem for joint innovation and value creation.

The energy storage industry’s competitive landscape has now shifted from scale-driven comparisons to a high-quality contest centered on core technology, system value, and ecosystem capability. EVE Energy is steering the industry toward a more sustainable path in its dual role as a technology innovator and ecosystem architect. Looking ahead, EVE Energy will leverage this milestone to continuously deepen the iteration of large battery technology and strengthen its capabilities in “Global Manufacturing, Global Cooperation, Global Service.” With an open approach, EVE Energy aims to collaborate with global partners to expand application scenarios for reliable energy storage technology, transforming innovation into inclusive power that supports the worldwide energy transition and contributes to the establishment of a clean, low-carbon new energy system.
