Jiangsu Yonggang Group Launches Suzhou's Largest User-Side ESS Power Station
The user-side ESS power station of Jiangsu Yonggang Group was recently connected to grid and put into operation. With a capacity of 134.1 MW/260.8 megawatt hours, the station became the largest user-side energy storage project in operation in Suzhou. The project is expected to deliver an annual discharge of 120 million kWh, helping the enterprise save over 40 million yuan in electricity costs each year. In terms of technology, the commissioned energy storage project adopted LFP battery and string-type technology systems, covering an area of approximately 23 mu. The project operates on a core model of "peak shaving and valley filling," implementing a daily strategy of two charges and two discharges: charging and storing electricity during valley periods, and discharging to support production during the noon peak and evening peak periods. Through this approach, the project precisely matched the production load curve, not only maximizing economic benefits and energy utilization efficiency, but also significantly improving PV absorption rates and effectively promoting the integration of green electricity into the entire production process.
