AI-Generated Summary
The EUREF-Energiewerkstatt (Energy Workshop) is the central energy hub of the EUREF-Campus in Berlin-Schöneberg, operated by GASAG Solution Plus GmbH. It serves as both the operational heart of the campus's CO₂-neutral energy supply and a publicly accessible demonstration facility where visitors can experience the future of district-level energy systems through guided tours.
The Energiewerkstatt's main component is a combined heat and power (CHP) plant fuelled by biomethane. The combustion process drives a generator producing electricity that is fed into the Berlin power grid, while the waste heat is used to produce hot water at 90°C, which is distributed to campus buildings through a 2.5-kilometre underground district heating pipeline. This system has enabled EUREF-Campus to meet Germany's federal climate targets for 2045 since 2014 — more than three decades ahead of schedule.
The facility also incorporates Germany's first combined power-to-heat and power-to-cold system, along with advanced microgrid technology. It has been the subject of several research projects exploring electricity market-oriented control, including a model predictive control framework that interfaces with day-ahead, intraday and experimental congestion management markets. These research outputs have been published in academic literature on microgrid optimisation.
GASAG Solution Plus GmbH, the operating company, offers energy concepts nationwide for the efficient provision of heat, electricity and cooling. The company's service spectrum includes planning, construction, financing and operation of energy generation systems.
For smart city practitioners, the EUREF-Energiewerkstatt demonstrates how a district-scale energy system can achieve climate neutrality through biomethane CHP, sector coupling and smart grid integration, while also serving as a public education and demonstration facility.
