Green technology provider Envision Energy and project developer ju:niz Energy have expanded their partnership in Germany, announcing the 442 MWh Smareg 13 (Vöhringen II) battery energy storage system (BESS) project in Bavaria.
Smareg 13 represents the third utility-scale storage installation jointly undertaken by the two companies, increasing their cumulative project portfolio to nearly 600 MWh. The facility will be constructed adjacent to the operational Smareg 12 BESS project, expanding regional grid balancing capacity in southern Germany.
Under the agreement, ju:niz Energy will manage full-lifecycle responsibilities—including project development, capital financing, construction, and long-term asset operation. Envision Energy will supply its Gen 8 BESS platform and provide ongoing technical integration.
Key technical, operational, and site specifications of the project include:
- Storage capacity: 442 MWh total storage volume featuring a four-hour discharge duration to support grid balancing.
- Technology deployment: Employs Envision’s Gen 8 BESS platform, integrating grid-forming capabilities to enhance frequency control and regional power system stability.
- Noise mitigation infrastructure: Incorporates specialized low-noise acoustic engineering designed for deployment in acoustically sensitive environments without reducing power throughput.
- Portfolio integration: Expands ju:niz Energy’s German BESS development pipeline, targeting grid congestion and integrating variable renewable generation.
Henry Peng, Senior Vice President of Envision Energy and President of EU & LATAM Regions, stated that expanding the agreement prior to the completion of their initial two joint projects highlights Envision’s role as a trusted technology partner and reflects growing demand for localized technical execution in Germany.
Vural Oezcan, Chief Operating Officer at ju:niz Energy, noted that combining advanced development timelines with four-hour storage technology will deliver critical flexibility to the German transmission grid as renewable energy penetration increases.
