Imagine a corporate campus that doesn’t just consume energy — but produces, stores, and trades it within its own community. At SAP’s headquarters in Walldorf, Germany, this vision has become reality.
In collaboration with exnaton, the SAP Energy Community brings prosumer energy sharing to life. It shows how large organizations can use technology and collaboration to make sustainability tangible — not only through targets and reporting, but through everyday action.
Energy systems are changing fast. Instead of one-way electricity flows from producer to consumer, we’re entering an era where energy moves in multiple directions — between buildings, electric vehicles, and people.
SAP is known globally as a leader in enterprise software that helps companies run better. But with the launch of its Energy Park and the new Energy Community at its Walldorf campus, SAP is taking a bold step beyond the office and into the energy transition itself.
The Energy Community enables employees and facilities to act as prosumers — producing, consuming, and trading renewable energy directly across the campus. It’s a microcosm of the decentralized, digital energy world that’s emerging across Europe.
Behind the scenes, exnaton’s intelligence platform for new energy powers the community’s operations.
Participants can easily sign up, monitor their energy production and consumption in real time, and trade energy with others across the campus. The software automates what used to be complex — from billing to peer-to-peer transactions — and presents it in a way anyone can understand.
The platform covers the full community lifecycle:
“The SAP Energy Community in Walldorf is a powerful step toward establishing a standardized model for energy sharing in Germany. By bringing our experience from international energy communities, we’re proud to support SAP in turning this vision into a scalable, real-world solution.”
— Anselma Wörner, Co-founder & COO, exnaton
At the heart of the community lies the S.MART Shop, a solar-powered facility equipped with EV chargers and a battery system. Previously, any surplus solar energy went straight into the grid with limited financial return. Now, thanks to exnaton’s technology, this energy can be shared locally — improving both sustainability and economic outcomes.
Participants benefit from lower costs, higher self-consumption of renewable energy, and a sense of ownership in the transition. For SAP, it’s a tangible demonstration of how enterprises can lead by example — using their own infrastructure as a testbed for innovation.
As Germany prepares for new regulations on energy sharing in 2026, the Walldorf Energy Community stands as a practical model for what’s possible. It shows how policy goals can be realized through digital platforms, trusted data, and collaboration between technology providers, utilities, and enterprises.
“By combining SAP’s solutions with innovative partner technologies like exnaton, we’ve built a robust platform that enables real-time energy insights, seamless energy transactions, and greater efficiency across the board.”
— Bruno Pincollini, Business Development – Industry Business Unit Energy and Utilities, SAP
SAP brings decades of experience in connecting people, data, and systems — helping organizations make better business decisions. exnaton brings cutting-edge expertise from the energy sector, having emerged as an ETH Zurich spin-off with a mission to accelerate the transition to renewable energy.
Together, they demonstrate what’s possible when enterprise technology meets energy innovation.
SAP contributes scale, reliability, and global perspective. exnaton contributes agility, domain expertise, and the software intelligence to turn energy sharing into an operational reality.
Today, exnaton supports more than 50 utilities across five countries, enabling use cases like energy sharing, dynamic tariffs, and EV smart charging. Projects like Walldorf show how the same technology can extend beyond utilities — into corporate campuses, housing associations, and local energy communities.
The SAP Energy Community is not a one-off pilot. It’s a signal of what’s next.
Enterprises worldwide are looking for new ways to cut emissions, stabilize energy costs, and involve their employees in sustainability. By transforming their campuses into living energy ecosystems, they can achieve all three — while inspiring others to follow.
At exnaton, we believe the future of energy is intelligent, decentralized, and participatory.
The Walldorf project is a powerful proof of how technology can turn that vision into practice — one community at a time.
