Interoperability depends on the collaboration of multiple domains. While technical interoperability in the energy sector is fairly well established, more attention needs to be given to the interoperability of functions and companies. Even when standards and interoperability models are defined, framework setters, product developers, and users must agree on their implementation and ensure that the solutions are compatible with the defined specifications. With the Interoperability Network for the Energy Transition (IntNET) project, an open, cross-domain community is created, bringing together all relevant actors in the European energy sector to collaborate on the development, testing, and implementation of interoperable energy services.

The Fraunhofer Center for Digital Energy coordinates a balanced and well-connected consortium of researchers (including RWTH Aachen University), framework setters (such as ministries and EU-wide associations), standardization experts, and communication experts. The community approach of IntNET ensures a broad reach.

The first public event involving int:net was the European Sustainable Energy Week (EUSEW), a significant event in the European energy landscape. This year, the EUSEW took place from September 26th to 30th under the theme "Going green and digital for Europe's energy transition." The event included a high-level policy conference, the EUSEW Awards, and the third European Youth Energy Day. At the EUSEW, participants had the opportunity to interact with representatives from int:net to learn about its goals, methodology, and possibilities for collaboration.
