Sieyuan Electric and CATL Have Signed a Three-year Memorandum of Understanding (MOU) on Energy Storage Cooperation

Recently, Sieyuan Electric and CATL have signed a three-year memorandum of understanding (MOU) on energy storage cooperation, targeting a cumulative BESS deployment capacity of 50GWh. Leveraging their respective core strengths, the two companies will jointly promote a market-oriented, mutual-sourcing procurement model for energy storage, with the aim of enhancing value-chain coordination and improving overall industry efficiency, supporting the high-quality development of the energy storage sector. The MOU was signed by Li Xiaobing, deputy general manager of Sieyuan Qingneng, and Li Yue, vice president for China at CATL’s Zero-Carbon Energy Business Unit, and witnessed by Dong Zengping, chairman of Sieyuan Electric, and Robin Zeng, chairman and CEO of CATL.

Over the next three years, the partnership will focus on mutual collaboration across upstream and downstream segments of the value chain, covering energy storage systems as well as supporting transmission and distribution equipment. In parallel, the two companies plan to strengthen technical exchanges and project-level cooperation, continuously enhancing integrated solution capabilities, improving delivery efficiency and system reliability, and accelerating the large-scale deployment of energy storage within the underway global energy transition.

CATL is a global leader engaged in the research, development, manufacturing and sales of power batteries and energy storage systems, with a strategic focus on replacing fossil fuels in both mobile and stationary applications, while enabling integrated innovation through electrification and digitalisation. The latest MOU marks a strategic deepening of the partnership established in 2022 and represents a new phase of collaboration between Sieyuan Electric and CATL. It further strengthens coordination across the energy storage value chain and provides the industry with a more robust, efficient and sustainable model for ecosystem-based collaboration, contributing in practical terms to global net-zero emissions goals, targets and the global energy transition.
