recently, Xuzhou zhonglian cement co., ltd., invested and constructed by Sinoma overseas, has successfully achieved a breakthrough in key nodes-full capacity grid connection will be completed on December 30, 2025 and live operation will be officially launched on March 16, 2026, marking the formal operation of the regional-level "hybrid energy storage photovoltaic" integrated demonstration project, injecting strong green kinetic energy into the low-carbon transformation of traditional industrial enterprises. The project deeply integrates photovoltaic power generation and hybrid energy storage technology to build a clean energy supply system with "spontaneous self-use, flexible regulation, safety and efficiency.
The total installed energy storage capacity of the project is 10MW/20MWh, and the total photovoltaic capacity is 11.38MW, forming a complete green energy link of "photovoltaic power generation hybrid energy storage, different from the single energy supply mode, the project captures clean electric energy through the photovoltaic system, and relies on the hybrid energy storage system to realize the storage, allocation and complementarity of electric energy, which can not only maximize the consumption of photovoltaic clean energy, avoid waste of light, but also accurately match the power demand of cement production, provide continuous and stable power support for the production process, and build a closed-loop intelligent energy system with deep integration of power generation side, energy storage side and power side, realize the intelligent coordination and optimal operation of energy production, storage, consumption and regulation of the whole life cycle.
on the technical route, the project breaks through the limitation of traditional single energy storage and adopts the hybrid energy storage innovation scheme of "lithium iron phosphate all vanadium liquid flow, configure 9.225MW/18.44MWh lithium iron phosphate battery and 0.5MW/2MWh all-vanadium redox flow battery. The advantages of the two technologies complement each other, lithium iron phosphate can quickly respond to short-term load fluctuations, all-vanadium liquid flow battery has both high safety and long life, to achieve the dual goal of "short-term peak-shaving long-term energy storage", adapt to the energy demand of the cement industry, and provide a replicable demonstration paradigm for industrial energy storage.
in the process of debugging the hybrid energy storage system of the project, facing multiple technical difficulties, the project team closely combined with the actual power consumption scenario of the cement plant, continuously optimize system integration and operational strategies. The project implementation team successfully overcame a series of technical difficulties by repeatedly debugging the optical storage EMS coordinated control algorithm and carrying out multiple rounds of simulation tests to accurately match the coordinated operation of the two energy storage technologies with photovoltaic systems and production loads, ensuring the smooth grid-connected operation of the energy storage power station, realizing real-time control of the charging and discharging power of the energy storage system, effectively increasing the charging and discharging amount, and ensuring the economic benefits of the energy storage power station.
the successful grid connection of Xuzhou zhonglian optical storage integration project not only builds a continuous and stable green energy supply system for Xuzhou zhonglian cement co., ltd., effectively optimizes the enterprise energy structure, accurately controls the electricity consumption cost, achieves the efficient linkage of source, network, load and storage integration, but also becomes an important demonstration project for Sinoma overseas to explore the application of optical storage integration in industrial scenarios in the field of new energy, truly realize the safe and controllable, green and low-carbon, efficient utilization and on-demand supply of energy, provide core guarantee for the new power system, and demonstrate the company's solid technical accumulation and rich practical experience in the research and development of hybrid energy storage technology and project landing. In the future, Sinoma Overseas will continue to deepen its new energy track, continuously strengthen its technological research and development and innovation strength, focus on the diversified application of optical storage integration technology in industrial scenarios, continuously optimize hybrid energy storage technology solutions, solve more technical problems in the industry, enable more industrial enterprises to embark on the fast lane of low-carbon transformation, help realize the national "double carbon" goal with solid industrial practice, and contribute to the construction of new power systems.
