On July 21, 2025, a major milestone in China's clean energy development has been achieved with the successful completion of Hami’s first large-scale vanadium flow battery energy storage project, located in the Shichengzi Photovoltaic Industrial Park. The 100MW/400MWh vanadium flow battery energy storage power station marks a significant step toward grid stability and efficient renewable energy utilization.
The project was invested and developed by Hami Dongtianshan Power Generation Co., Ltd., with energy storage equipment supplied by Dalian Rongke Power Co., Ltd. and full design and construction undertaken by PowerChina Northwest Engineering Corporation Limited.
Through a dynamic charge-discharge mechanism, the station stores surplus solar energy generated during midday and releases it during peak demand periods in the morning and evening, significantly improving the absorption rate of renewable energy. Final commissioning of the storage system and its connection to a 110kV substation is currently underway to ensure smooth grid integration.
As a flagship project of the “renewable energy + storage” model, the plant offers a long cycle life and high operational safety. “Its core value lies in overcoming the intermittency of wind and solar power,” said Kang Liming, station manager of the Shichengzi Photovoltaic Power Station. “The system not only enhances grid stability but also maximizes the efficiency of renewable energy use. It stores surplus electricity and provides rapid response capabilities, supporting frequency regulation and improving the overall reliability of power supply.”
In 2025, Hami has prioritized integrated energy development. By advancing high-end equipment manufacturing, applying new energy storage technologies, and strengthening full-cycle project management, the city is accelerating the transformation of energy resources. This initiative offers a replicable model for the green transition of China's energy structure.
