Jinko ESS has announced that it has secured a 150MWh energy storage project in Germany, deploying 30 units of its G2 system (5MWh per unit), integrated into 20-foot standardized containers. Deliveries are scheduled from late October to mid-November 2025.
The G2 system achieves a leading 94% round-trip efficiency and supports long duration storage, enabling grid frequency regulation and enhanced renewable energy integration to increase ROI for customers. Its compact design aligns with Europe’s land-resource efficiency goals.
The system employs liquid cooling to maintain cell temperature differentials within ±2.5°C, coupled with multi-level fire isolation and smart early-warning mechanisms to prevent thermal risks. Integrated with an AI-driven cloud platform, it optimizes energy efficiency and reduces auxiliary power consumption by 20% through on-demand cooling, saving operators tens of thousands of euros annually.
Jinko ESS GM for Europe Roberto Murgioni commented: “This project validates Europe’s demand for high-efficiency, safe storage solutions. Jinko ESS is delighted to provide its liquid-cooled technology to support Germany’s clean energy transition.”
