Xiangyang, a renowned national historical and cultural city, boasts the third-largest railway marshalling yard in China and the largest in Hubei Province. It stands as a new industrial base and the central hub of northwestern Hubei. As the sub-central city with the foremost comprehensive economic strength in central Hubei, Xiangyang Municipal Government has consistently adhered to the development principle of "building and strengthening the city through industry," meticulously planning its industrial layout. However, with the accelerated industrialization and continuous deepening of industrial upgrading, Xiangyang faces increasingly severe resource constraints, particularly regarding electric power, a core element for modern industrial development. The stability and efficient utilization of electric power supply, as well as the implementation of the “cost reduction and efficiency enhancement” strategy, directly impact the sustainable growth and competitiveness of Xiangyang's industrial enterprises.

To address this issue, TWS Anhui proposed an "industry+ ESS" solution for a local large-scale glassware manufacturing enterprise specializing in pharmaceutical glass tubes. Through systematic exploration, analysis, and calculation, and taking into full consideration the capacity and distribution of transformers in the industrial park, the technical team of TWS Anhui helped customize a 1.05MW/2.15MWh energy storage system, consisting of two sub-systems in parallel. This system comprises 10 MU-P C&I liquid-cooling energy storage cabinets and 2 grid-connected cabinets. This "industry+ ESS" solution deeply integrates cutting-edge energy storage technology with an intelligent management system, and supports PV-storage-charging applications, aiming to create an efficient, stable, and eco-friendly energy supply system.

The project adopts the MU-P C&l outdoor liquid-cooling energy storage cabinet independently developed by TWS Anhui. The MU-P C&l cabinet is economically efficient, safe and reliable, intelligent, and user-friendly. It features a compact design with a single cabinet occupying an area of only 1.23m². By placing multiple cabinets side by side in parallel, the solution maximumly utilizes the limited space on site. Considering the local two-part tariff pricing as well as Hubei's time-of-use electricity pricing policy, TWS Anhui takes advantage of peak-valley pricing differences to optimize electricity usage periods and introduce efficient energy storage, achieving intelligent energy management. Through the peak-valley arbitrage, the project can generate revenues of approximately CNY 3,000 on a daily basis, with an expected payback period of 3 years, enabling the enterprise to quickly recoup costs and enjoy continuous and stable profits.

The successful implementation and operation of the 1.05MW/2.15MWh energy storage system have addressed the customer's electricity needs and cut down its operational expenses. Meanwhile, the enterprise's market competitiveness and sustainable development potential have been enhanced. Looking ahead, TWS Anhui will continue to deepen its presence in the energy storage sector, providing safer, more efficient, and smarter energy storage systems and services. Upholding the principle of mutual benefit and win-win cooperation, TWS Anhui looks forward to collaborating with more industry partners to jointly drive industrial upgrading, optimize regional economic structure, and inject robust momentum into China's green and sustainable development.
