ODEON's primary objective is to revolutionise the Digital Energy transition in the EU. By integrating Smart IoT Platforms and decentralized intelligence, the project aims to enhance resilience and sustainability. With a focus on reducing dependence on external sources, ODEON advocates for the intensified integration of Renewable Energy Sources (RES) in key sectors. The key technological components, including the ODEON Cloud-Edge Data and Intelligence Service Platform, ensure a reliable, and scalable framework. The collaborative nature of the project aligns with the objectives of the Digitalization of Energy Action Plan (DoEAP), with validation through large-scale demonstrations across several European countries for successful replication and market uptake.
