The HEDGE-IoT project supports the EU’s green and digital transition goals by enabling a resilient, decarbonized, and consumer-centric energy ecosystem through interoperable AI-IoT Edge-Cloud solutions. As Europe moves toward higher shares of renewable energy, the energy system faces complexity, fragmentation, and a growing need for secure, seamless interoperability among devices, platforms, and stakeholders. Addressing critical gaps such as data silos, lack of standardization, and limited real-time intelligence, HEDGE-IoT aims to accelerate the digital transformation of the energy sector. In response to strategic EU initiatives—including the European Green Deal, REPowerEU, and the Digitalisation of Energy Action Plan—HEDGE-IoT introduces a novel federated digital framework. This framework deploys IoT assets across all grid levels, enhances them with edge/cloud intelligence, and integrates AI/ML tools and distributed computing. It also leverages the concept of Energy Data Spaces to enable secure, interoperable data sharing and service integration across stakeholders. This approach unlocks flexibility potential, improves RES hosting capacity, and strengthens grid resilience. The HEDGE-IoT ecosystem compirses four main pillars as seen in the Figure 1 (attached): Technology Facilitator, Interoperability, Standardisation, and Digital Energy Ecosystem Enabling. The project demonstrates these innovations through six large-scale pilots in diverse European settings, ensuring scalability and transferability. By engaging stakeholders, aligning with EU standardization efforts, and supporting SMEs via an Open Call mechanism, HEDGE-IoT fosters innovation, strengthens the European digital energy market, and contributes to EU policy goals.
