Battery energy storage is rapidly evolving from an auxiliary facility into a core infrastructure supporting new power systems, safe energy use, and energy resilience. The high proportion of renewable energy connected to the grid, accelerated power market reforms, continuous growth in electrification load, and rapid expansion of new energy consumption scenarios such as data centers, 5G communications, and electric vehicles are posing unprecedented challenges to the flexibility, stability, and economy of power system. The value of energy storage technology in peak shaving and frequency regulation, capacity support, system stability, and market trading is increasingly prominent, making it a crucial tool for global energy system transformation. Simultaneously, the European energy crisis, restructuring of the US power system, and rapid development of new energy sources in emerging markets have significantly driven the explosive growth of the global energy storage market. China is accelerating its transition from largest "scale expansion" to "high-quality development," entering a critical stage in technological innovation, system integration, power market participation, and globalization. "Going global" is not merely about exporting products and production capacity, but also about competing globally in terms of technical standards, business models, and system solutions. The China Battery Energy Storage Summit 2026 will bring together leading global energy technology providers, grid companies, end-users, and investment institutions to engage in in-depth discussions on global energy storage market trends, electricity market mechanisms, commercial and stand-alone energy storage business models, next-generation battery technologies, grid-based energy storage, virtual power plants, and the application in data centers and charging infrastructure. The summit aims to establish a high-level, international exchange platform to promote the coordinated development of the energy storage industry in China and globally, and accelerate the large-scale and commercial deployment of energy storage in new power systems.
