A partnership that grows with every project: be.storaged at Sungrow Utility Connect Germany 2026 in Berlin
On October 7, 2026, the energy storage and PV industries gathered at the Spreespeicher in Berlin for Sungrow Utility Connect Germany. be.storaged was there with three colleagues. In her presentation, Corinna Petznik explained how an initial joint project with Sungrow evolved into a long-term partnership.
Sungrow hosted Utility Connect Germany for the third time this year. The event focused on large-scale photovoltaic systems and battery storage, covering market developments, grid requirements, new technologies, and pioneering projects. Representing be.storaged at the event were Corinna Petznik (Supplier Manager), Kevin Hendzlik (Head of Supplier Management), and Yannik Maskow (Sales Manager C&I).
Built to Last: Sungrow × be.storaged
In a presentation titled “A Partnership That Grew With Every Project,” Corinna Petznik recounted our shared history from a procurement perspective. She is responsible for purchasing battery systems for our projects and is therefore the direct point of contact for Sungrow.
The collaboration began in 2024 in Untersteinach, Bavaria. That’s where our first utility-scale project with Sungrow was built: eight PowerTitan 1.0 containers with a capacity of approximately 20 MWh and an output of 10 MW, which have been in operation since 2025. Next came the Dirkshof project in Reußenköge, North Frisia—a battery storage facility located right next to a community wind farm with a shared grid connection. Here, too, there are eight containers, but equipped with PowerTitan 2.0 units, offering twice the capacity: 40 MWh with 20 MW of power output.
Today, we have 13 project sites with Sungrow—either completed or under construction—throughout Germany, from North Frisia to Bavaria and Saxony. Together, they have a total storage capacity of more than 670 MWh.
What Has Changed
Corinna showed what has happened between Untersteinach and Dirkshof. Technology has come a long way. Processes have become more efficient because requirements are now defined more clearly right from the start of a project. And what started as a single project has evolved into a collaboration with direct points of contact and streamlined communication. If something on the construction site doesn’t go as planned, the teams work together to find a solution. Corinna summed it up this way: “Untersteinach was a project. What we’re building now is a partnership designed to last.”
Many good conversations
In addition to the presentations and a panel discussion on grid-integrated solar and energy storage technology, there was plenty of time for discussion—both during the afternoon networking session and at the group dinner that evening. Our team had many interesting conversations with partners, customers, and industry colleagues and brought new ideas back to Oldenburg.
Many thanks to Sungrow for the invitation and the successful event. We look forward to our next joint projects.
