The EUREF-Energiewerkstatt is the central energy supply and public demonstration facility on EUREF-Campus in Berlin-Schöneberg, operated by GASAG Solution Plus GmbH. Located on the approximately 5.5-hectare campus surrounding the landmark Schöneberg Gasometer, it serves as the technical backbone that enabled EUREF-Campus to meet the German federal government's CO2 climate targets for 2045 as early as 2014.
The facility features a biomethane-fuelled combined heat and power (CHP) plant running on certified biomethane, supplying all campus buildings with climate-neutral electricity, heating, and cooling. It also houses Germany's first combined power-to-heat and power-to-cold system, integrated into an advanced microgrid that manages energy flows across the district. A district heating pipeline connects the various buildings on campus, ensuring efficient distribution of thermal energy. The smart energy grid enables real-time optimisation of generation, storage, and consumption across the campus.
Beyond its operational role, the EUREF-Energiewerkstatt functions as a public education and experience centre. Guided tours allow visitors to see the energy infrastructure first-hand and understand how the individual components — CHP, heat pumps, smart grid controls, and storage systems — interact to deliver a fully CO2-neutral energy supply at district scale.
GASAG Solution Plus GmbH, the operator, provides energy concepts across Germany, specialising in planning, financing, and operating decentralised energy generation systems. EUREF-Campus itself hosts more than 150 companies, research institutions, and start-ups, with around 7,000 people working in the areas of energy, mobility, and sustainability. The Energiewerkstatt is a core demonstration of how integrated district-level energy systems can achieve climate neutrality in practice.
