On September 29, Wintime Energy, through its subsidiary Beijing Detai Energy Storage Technology Co., Ltd., successfully commissioned its 1.5 MW/6 MWh vanadium flow battery solar storage integrated power station. After passing a 72-hour trial run, the project is now fully operational.
This project, one of Shanxi Province's leading integrated vanadium flow battery solar storage and charging stations, marks a significant milestone for Detai Energy Storage in the field of new energy storage. The successful construction and operation of this project validate the reliability and stability of the company’s energy storage products and systems. This also lays a strong foundation for future R&D, design, construction, and market expansion of vanadium flow battery systems.
The project is located at Shanxi Kangwei Group Co., Ltd. in Qinyuan County and takes advantage of concentrated rooftop resources from nearby coal mines and washing plants. The project integrates a distributed photovoltaic (PV) power generation system with a vanadium flow battery storage system, using advanced control technologies to store surplus solar energy, which is later used for off-peak power supply and charging electric vehicles. The station has a total rooftop PV capacity of 2.7 MWp across 22 arrays, generating an annual grid supply of 3073.26 MWh.
The energy storage system consists of six vanadium flow battery units, each comprising 250kW stack modules. The system also includes a liquid storage tank, pipelines, energy storage transformers, and power conversion systems, all designed and implemented by Detai Energy Storage.
Throughout its trial operation, the station achieved full power output, thoroughly testing the stability and reliability of the storage system’s components, including the stack modules, power conversion system, control system, and cooling system. The project showcases high efficiency, flexibility, and environmental friendliness while offering low maintenance costs and effective energy dispatching capabilities.
Wintime Energy’s continued investment in energy storage innovation is exemplified through this project, contributing to its strategic goal of developing a dual-driven model of "traditional energy + new energy storage." The company is on track to establish a full supply chain in the vanadium flow battery industry, with further plans to scale its energy storage projects by 2025, and aims to capture over 30% of the vanadium flow battery market by 2027-2030.
