Jinko ESS, a global leading energy storage company and a subsidiary of Jinko Solar Co., Ltd. has further expanded its European presence with the signing of a 15MWh utility-scale energy storage project in Slovenia. The project will feature three of Jinko ESS's advanced Utility G2, 5MWh containerized battery energy storage systems, with delivery scheduled for the first quarter of 2026. This agreement highlights the growing confidence in Jinko ESS's technology to provide robust and reliable grid-scale solutions.
The selection of the Utility G2 system for this project was driven by its unparalleled combination of efficiency, safety, and total cost of ownership. The system delivers superior value by offering the market's leading system-level efficiency of up to 94%, ensuring more energy is delivered back to the grid. Its industry-high energy density packs 5MWh into a standard 20-foot container, while its precision liquid cooling system—which reduces energy consumption by 30% and maintains a critical 2°C temperature differential between cells—guarantees both enhanced safety and long-term performance. Jinko ESS provides a top-tier product that is not only technologically advanced but also the most affordable solution over its lifecycle.
"This project is a testament to our commitment to delivering cutting-edge energy storage technology that meets the precise needs of the European market," said Roberto Murgioni, General Manager at Jinko ESS EU. "Our Utility G2 system is engineered to provide the efficiency, reliability, and safety that utilities and developers require to stabilize the grid and integrate renewable energy at scale. We are proud to contribute to Slovenia's clean energy goals."
