Against the backdrop of the national "Dual Carbon" goals and the industry's major trend of constructing a "New Energy-dominated Power System," various favorable policies are emerging one after another. The position of industrial and commercial energy storage within the market is gradually being clarified, and the commercialization and profit channels of industrial and commercial energy storage are becoming increasingly clear.
Zhejiang Province has a superior peak-to-valley electricity price difference and provincial and regional industrial support policies continue to be introduced. Direct subsidy policies for industrial and commercial energy storage in prefectures, cities and counties are intensively released, such as energy storage and discharge subsidies in Ouhai District and Longgang, Wenzhou, Zhejiang, as high as 0.8 RMB/kWh. Some research institutions estimate that the IRR of industrial and commercial energy storage in Zhejiang Province (two charging and two discharging, and a financing ratio of 70%) has exceeded 40%, and the investment return cycle has been shortened to about 3 years.
- On January 18th, 2024, the 0.5MW/1MWh energy storage demonstration project of Zhoushan Ningshing Ship Building & Repairing Co., Ltd was successfully completed and put into operation -
Zhoushan Ningshing Ship Building & Repairing Co., Ltd., established in 2019, is an enterprise primarily engaged in the manufacturing of railways, ships, aerospace, and other transportation equipment. The annual total electricity consumption is 394kWh. Considering the peak and off-peak electricity pricing periods in Zhejiang Province, the electricity consumption during peak and off-peak hours accounts for nearly 70%. After implementing energy storage and capacity expansion, it is advantageous for peak shaving and load balancing, easing the transformer load and reducing monthly electricity expenses. The payback period is short, and the investment returns are considerable, visible, and sustainable.
Modular Customization Helps Enterprises Reduce Costs and Increase Efficiency
Based on the analysis of customer electricity consumption data, this project has customized and configured an integrated energy storage cabinet. The operating mode is "2 charges and 2 discharges," which means two charge-discharge cycles per day. Austa's Energy Storage Cabinet adopts the design concept of "AII IN ONE," integrating long-life battery cells, battery management system (BMS), high-performance power conversion system (PCS), active safety system, and thermal management system into a single standardized outdoor cabinet. It forms an integrated plug-and-play smart energy block, making the energy block product a true transition from engineering to productization in energy storage systems.
The Austa Cloud, an energy cloud, adopts a storage method based on time-series database, enabling it to have the capability of displaying and storing the voltage and temperature of every battery cell in the energy storage system in real-time. It supports the traceability of operational data and fault waveform recording of energy storage power stations in any past time period. Austa Cloud realizes the mining and analysis of thermal management operational data and battery health of energy storage devices, empowering power station decision-making, judgment, and risk prediction, and enabling true unmanned operation of energy storage power stations.
The establishment of this energy storage demonstration project is an important step for Ningbo Austa Solar Tech Co., LTD. in the energy storage market. It will strongly support the implementation of its Panels Storage Charging Integrated Solution in the domestic market, laying a solid foundation for expanding into more regions in the future. Moving forward, Austa will focus on the research and development of core technologies for optical storage charging, continuously promote the application of integrated solutions, empower customers, accelerate the transformation of energy structure and carbon neutrality process, facilitate corporate green transformation, drive global energy transition, and inject Austa's power into global zero-carbon development.
