USEFLEDS - Unleashing Sector-coupling Flexibility by means of an Energy Data Space explores the development of a shared data exchange for the energy sector. A co-creation workspace connects the work package topics of data economy, governance, energy economy, data spaces, and artificial intelligence in iterative process steps across projects. Based on these project focal areas, the foundation for a joint data exchange is created, enabling the development of data-driven services to benefit the energy transition and achieve climate goals.
