Connect. Build. Commit.
The X-Regional Summit 2026 brings together the people building the future of E.ON's Energy Retail technology — across regions, platforms, and teams. Over three days in Berlin, colleagues from the Digital, Data, Core, and Flex platforms come together to connect, build side by side, and align on where we're heading in 2026. It's part working session, part hackathon, part the kind of face-to-face conversation that moves things forward faster than any call ever could. This is where cross-regional collaboration stops being a slide and starts being real.
