As a hub city and regional economic center in the Guangdong-Hong Kong-Macao Greater Bay Area, Guangzhou’s transition to “Intelligent Manufacturing ” and expanding industrial matrix like AI and new energy drive soaring power demand. Mingmei Science and Technology Park in Guangzhou experiences significant energy challenges: high power loads and stringent stability requirements from integrated manufacturing, data centers, and services; peak-valley electricity price pressures; and transformer capacity limits. Therefore, ensuring power supply reliability while balancing economic efficiency and clean energy consumption has become a core issue for its high-quality development and energy management.
In July 2025, a breakthrough solution emerged for this challenge—the 1 MW/2 MWh BESS project developed by TWS Technology was officially put into operation, providing a benchmark model for energy management in industrial parks in the Greater Bay Area. The project employs a dual-system architecture consisting of six MU-P10 and three MU-Max10 ESS cabinets, along with two grid-connection cabinets. Integrated with an AI load forecasting algorithm, the system enables precise peak-valley arbitrage scheduling. The MU-M10 cabinets utilize liquid cooling temperature control technology, maintaining a battery temperature difference control accuracy of ±1.5°C even under high-temperature operating conditions of 45°C, with the overall cycle efficiency of the system reaching an industry-leading 97%.
This project delivers multi-dimensional value to Mingmei Science and Technology Park:
- Cost Reduction:Strategic peak-valley arbitrage significantly lowers electricity expenses.
- Enhanced Security & Reliability:Millisecond-level grid switching provides highly reliable backup power, ensuring uninterrupted supply for critical loads like data centers.
- Green Transition:Advanced energy management algorithms dynamically optimize charging/discharging, increasing renewable energy consumption by over 30%.
- Carbon Reduction:Projected to cut ~1,500 tons of CO2 annually (equivalent to 80,000 trees' sequestration).
The successful implementation of the energy storage project demonstrates that smart energy management can simultaneously achieve power reliability, economic returns, and environmental benefits. It not only resolves energy management challenges for high-load park but also pioneers a replicable, scalable green pathway, marking a landmark practice for the Greater Bay Area's industrial green transformation. Looking ahead, TWS Technology will continue to deepen technological innovation, promote the deployment of energy storage systems in more application scenarios, to assist the Greater Bay Area in building a world-class clean energy demonstration zone, and contribute to the realization of the nation’s “dual carbon” strategic goals.
