Envision Energy and ju:niz Energy have expanded their partnership with the 442 MWh Smareg 13 (Vöhringen II) battery energy storage system (BESS) project in Bavaria, Germany. Announced on 9 November 2026, the project is the third joint development between the companies, bringing their combined storage capacity to nearly 600 MWh. Envision Energy provides battery storage technology and project delivery capabilities, while ju:niz Energy specialises in developing and operating large-scale battery storage projects.
The Smareg 13 project is located adjacent to the operational Smareg 12 facility in Vöhringen. ju:niz Energy will be responsible for the project's development, financing and realisation, along with its long-term operation. The project forms part of the company's expanding German battery storage portfolio, which covers development, financing, construction and operation throughout the project lifecycle.
Smareg 13 will deploy Envision Energy's Gen 8 BESS platform, incorporating four-hour energy storage, advanced battery technology and grid-forming capabilities. The system is designed to provide grid support, flexibility and balancing services as Germany integrates increasing amounts of renewable energy. Its low-noise design also addresses acoustic requirements at the project location, allowing deployment in noise-sensitive environments without affecting operational capabilities.
Henry Peng, Senior Vice President of Envision Energy and President of its EU and LATAM Regions, said the larger project reflects the continued cooperation between the companies. He noted that the partnership is progressing with Smareg 13 before delivery of the first two joint projects has been completed. Envision is also expanding its local capabilities in Germany as part of the collaboration.
Vural Oezcan, Chief Operating Officer of ju:niz Energy, said Smareg 13 represents another step in developing the company's battery storage portfolio. He highlighted the project's advanced development status and four-hour storage technology, alongside its expected contribution to grid flexibility and system stability.
