Jinko ESS has announced the deployment of 90 SunGiga 261kWh C&I energy storage systems in Binzhou, China’s Shandong Province. With a total capacity of 23.49MWh, the project integrates energy storage with on-site solar PV generation, electricity loads and EV charging facilities to establish an integrated “source-grid-load-storage” solution. Under centralized dispatch by a station-level Energy Management System (EMS), the storage systems are further connected to a Virtual Power Plant (VPP) platform to participate in demand response and power spot market trading, exploring a new pathway for C&I energy storage to evolve from standalone energy cost optimization toward diversified energy value creation.
The deployment of 90 storage systems places higher demands on coordinated dispatch and long-term operational performance. The SunGiga 261kWh features a highly integrated architecture, supporting up to 12 units in parallel, and works with the station-level EMS to enable centralized management and flexible dispatch of multiple storage units, providing a foundation for coordinated source-grid-load-storage operations and participation in diversified energy markets.
As demand response and power market trading require more flexible charging and discharging strategies, the system achieves a maximum PCS conversion efficiency of ≥98.5% and system efficiency of ≥90%, while reducing auxiliary power consumption by 20%, improving overall energy conversion efficiency and minimizing the system’s own energy consumption to support more efficient operation across diversified market applications. For long-term and frequent cycling, the system adopts intelligent liquid-cooling technology to maintain a cell temperature difference within 2℃, while its system design life of up to 15 years provides further support for stable, long-term operation.
Jinko ESS China GM Damon Duan commented: “As electricity market reforms continue to advance, C&I energy storage is evolving from a conventional peak-valley arbitrage tool into an important energy asset connecting customer-side resources with electricity markets. The Binzhou project demonstrates how the coordinated dispatch of 90 storage systems, together with solar PV, electricity loads and EV charging facilities, can support participation in demand response and power market trading, creating new opportunities for the diversified value of C&I energy storage.”
