Jinko ESS, the global leading energy storage company recently announced the successful signing of a 100MWh energy storage project with a key client in Greece. The project will deploy 20 sets of Jinko ESS G2 5MWh liquid-cooled energy storage systems (configured for four-hour long-duration storage), distributed across 20 distinct project sites throughout Greece. Deliveries are scheduled to commence in mid-November 2025. This collaboration marks Jinko ESS’s continued expansion in Europe’s distributed energy storage sector, supporting Greece’s efforts to build a flexible and stable clean energy grid.

The Jinko ESS G2 5MWh system delivers a leading 94% round-trip efficiency, with its four-hour long-duration design enabling active participation in grid peak shaving, load shifting, and renewable energy integration, significantly enhancing power system economics and reliability. The modular containerized structure aligns with Greece’s mountainous terrain and scattered island geography, allowing flexible deployment across 20 sites to alleviate regional grid congestion and accelerate local wind and solar energy utilization. The system employs liquid cooling technology to maintain cell temperature differentials within ±2.5°C, combined with multi-layer fire-resistant isolation compartments and a thermal runaway early-warning system, providing triple-layer protection from cells to racks and the entire system, ensuring high reliability for frequent operational maintenance.

Integrated with Jinko ESS’s proprietary Energy Management cloud platform, the system enables real-time monitoring of all 20 sites and optimizes charge-discharge strategies. Its on-demand directional cooling technology reduces auxiliary energy consumption by 20% compared to conventional solutions. Coupled with the revenue advantages of the four-hour long-duration configuration, the system is projected to save operators tens of thousands of euros in annual operational costs.

Roberto Murgioni, General Manager of Jinko ESS Europe, stated: “Greece is accelerating progress toward its ‘70% renewable energy by 2030’ target. This innovative multi-site project not only demonstrates the G2 5MWh system’s adaptability to diverse scenarios but also delivers a cost-effective Jinko solution for Europe’s energy transition.”
