This document describes, in short, the key results and the exploitation strategy and sustainability plans for the int:net project (Interoperability Network for the Energy Transition). This EU Horizon Europe funded project lasted 3.5-years and aimed at establishing a comprehensive framework for energy system interoperability across Europe. Various tools and a state-of-the-art knowledge management and collaboration platform will support the further development of the interoperability community that int:net has created. Each consortium partner developed exploitation strategies aligned with their missions. Several partners participate in follow-up initiatives including the INSIEME project and EC’s Digital for Energy Initiative (D4E), ensuring continuity of the interoperability work.
