Cologne, Germany. The EEBUSummit 2025, which took place on 24 and 25 September in Cologne, was once again a great success. Around 280 participants from 145 different companies, numerous specialist presentations and practical demonstrations made it clear that EEBUS, as an open interface, plays a central role in integrating flexibility, customer orientation and market mechanisms into the energy system of the future.
The first day of the event opened with a welcome address by the EEBus Initiative e.V. and specialist presentations by BET and the Federal Office for Information Security (BSI), among others, which highlighted the regulatory framework surrounding §14a of the Energy Industry Act (EnWG) and §9 of the Renewable Energy Sources Act (EEG) and secure control via the smart meter gateway.
Further presentations addressed the new commissioning process of the EEBus Initiative in cooperation with the BSI and VDE FNN. In the afternoon, the focus was on specific implementation paths, including the control of energy management systems via the smart meter gateway, the current status of metering point operators, the integration of EMS systems, and conformity and certification requirements. Special attention was paid to the presentation of EEBUS’s own test software and the planned certification process. This was followed by a demonstration of simplified commissioning by craft businesses. The day ended with a well-attended networking event that provided an opportunity for informal exchange.
The technical Plugfest and live demos took place alongside the conference programme, providing an important forum for testing interoperability in practice and strengthening technical alignment across industries.
The second day of the event began with the start of the ‘Dynamic Tariffs & Flexibility’ theme block. This was followed by a discussion of the importance of variable tariffs for the grid and consumers, as well as the need for standardised tariff models to avoid manufacturer dependencies. Other topics included the role of interoperability in the building sector in the context of the Energy Performance of Buildings Directive (EPBD) and use cases for market-based avoidance of grid congestion. The afternoon opened with an international panel discussion on global market trends, supplemented by external perspectives on EEBUS in the European context and the status of EEBUS’s integration into international standardisation processes. The event concluded with a joint look at the next steps for the initiative and its role as a central communication technology in the energy system.
