EDDIE (European Distributed Data Infrastructure for Energy) is a Horizon Europe Innovation Action building the open-source dataspace infrastructure that will underpin Europe’s flexibility markets. Beyond its technical ambition, EDDIE addresses a strategic imperative: European energy service providers operate in a fragmented digital landscape that limits their ability to scale across borders, while global technology players increasingly compete to own the data layer of the energy transition. Digital4Grids joined EDDIE as a full consortium partner, bringing 25 years of control room and grid-edge architecture experience, with a conviction that open, standardised data exchange — rather than proprietary integration — is the path to a competitive European energy services industry capable of scaling its solutions worldwide.
Digital4Grids took a leading role in WP6, integrating EDDIE’s dataspace services into its Technical Aggregation platform and deploying them in a live French pilot connecting five real prosumer homes. The implementation covers the full flexibility lifecycle — from user consent and DER registration, through baseline nomination, mFRR bid submission and activation, to post-event settlement — orchestrated over a Kafka-based real-time streaming backbone and governed by IEC 62325 ESMP and IEC 62746-4 message standards.
The platform connects heterogeneous devices (EV chargers, home batteries, solar PV) through a multi-protocol translation layer (OpenADR, MQTT, OCPP, Saref), while a CIM-based data dictionary ensures semantic interoperability across all actors. This architecture is explicitly aligned with the CEEDs BluePrint, making it directly reusable across EU member states and exportable as a reference model to global markets.
EDDIE delivered, through Digital4Grids, a functioning end-to-end flexibility dataspace validated in live conditions — a rare achievement in European energy digitalisation. The pilot demonstrated that residential prosumers can participate in automated intraday flexibility trading with full transparency on energy flows and revenue attribution, establishing a quantified business case for the next generation of flexible home assets. More strategically, the standards and architecture produced — IEC 62746-4 message profiles, CIM-based semantic layers, Kafka-driven dataspace orchestration — constitute reusable building blocks that European energy service companies can deploy competitively at home and export globally, at a moment when energy system digitalisation is accelerating across every major market from North America to Southeast Asia.
