Envision Energy, a global leader in green technology, and ju:niz Energy are expanding their partnership with the 442 MWh Smareg 13 (Vöhringen II) battery energy storage system project in Bavaria, Germany.

Third Joint Project in a Deepening Partnership

Announced in Vöhringen, the project marks a significant next step in the collaboration between the two companies and is intended to contribute to the further expansion of large-scale energy storage in Germany.

Smareg 13 is the third project jointly realized by Envision and ju:niz Energy, bringing the total volume of their collaboration to nearly 600 MWh. According to the companies, the growing scale of the partnership reflects the strength of their cooperation, which combines ju:niz Energy's expertise in the development and long-term operation of large-scale battery storage projects with Envision Energy's BESS technology and project delivery capabilities.

ju:niz Energy Leads Development and Long-Term Operation

ju:niz Energy is responsible for the development, financing and realization of Smareg 13 and will operate the battery storage system over the long term. The project forms part of the company's growing German BESS portfolio and reflects its strategy of developing, financing, building and operating large-scale storage infrastructure across the full project lifecycle.

Founded in 2014, ju:niz Energy GmbH has been developing, implementing and operating battery storage systems that integrate renewable energy into the power grid and make it flexibly available.

The company covers the entire value chain, from site analysis and technical design to implementation and long-term operation. In addition to its own projects, ju:niz Energy pursues a co-development approach in which it participates in ongoing energy storage projects, contributing capital, technical expertise and operational know-how, and continues developing these projects with partners through commissioning and beyond.

Gen 8 Technology and Low-Noise Design Address Site Challenges

Smareg 13 will deploy Envision's advanced Gen 8 BESS platform, which combines four-hour energy storage, advanced battery technology and grid-forming capabilities to deliver high-performance energy storage and enhanced grid support.

The platform's low-noise design enables deployment in acoustically sensitive environments without compromising operational capability, a factor the companies describe as one of the key site challenges for Smareg 13.

The project is located adjacent to the operational Smareg 12 facility and will further strengthen storage capacity in Bavaria, providing greater flexibility and balancing capability as Germany integrates a growing share of renewable energy.

Executive Statements Highlight Trust and Scale

Henry Peng, Senior Vice President at Envision Energy and President of the EU & LATAM Regions, said the continued expansion of the partnership with ju:niz reflects the trust built through close cooperation and consistent execution.

"Moving forward with a significantly larger project before our first two projects have completed delivery demonstrates Envision's role as a trusted long-term technology partner," Peng said. "With Smareg 13, we are bringing together our Gen 8 BESS technology and expanding local capabilities in Germany to help build the flexible, resilient energy infrastructure required for the country's next phase of renewable energy growth."

Vural Oezcan, COO at ju:niz Energy, described Smareg 13 as another major step in the development of the company's battery storage portfolio. "The project combines a very advanced development status with four-hour storage technology and will make an important contribution to flexibility and system stability," Oezcan said. "Envision has proven to be a strong technology partner in our existing cooperation, and we are pleased to expand this collaboration with a project of this scale."

A Growing German Storage Market

The announcement comes as Germany works to integrate a growing share of renewable energy into its power system, a shift the companies say requires greater flexibility and balancing capability from large-scale storage. ju:niz Energy positions its projects as a contribution to the energy transition and the stability of power grids, with systems described as cost-effective, reliable and designed for long-term use.

With Smareg 13's 442 MWh capacity, the Envision–ju:niz collaboration approaches a combined volume of nearly 600 MWh across three projects, all situated in Germany. The companies have not announced details beyond those stated in the announcement regarding timelines for delivery or commissioning of the new facility.

ju:niz Energy GmbH is headquartered at Einsteinring 43, 85609 Aschheim. Envision Energy continues to position itself as a long-term technology partner in the German market, with Smareg 13 representing its largest jointly realized project with ju:niz Energy to date.
