Main objective is to create a dependable, scalable, and extensible European Distributed Data Infrastructure for Energy Framework (see Figure 1 – Grouping of data access challenges to get to a uniform interface below) streamlining the access to (1) data accessible through data-sharing infrastructure (e.g., grid operators, connection point registries, etc.) (2) in-house citizen data and (3) publicly available data (like price signals from exchanges or information on the current electricity mix available). Instead of intervening with national data management scenarios, the solution encapsulates European and regional diversity, and allows for services to act on a unified European interface. The complexity behind will be handled by the open-source EDDIE Framework. The functionalities that cannot be unified (e.g., onboarding/registration for national market communication), are streamlined to minimize integration efforts for data-driven services. Active European customers get a trusted and unique user experience to manage their energy data-sharing. Near real-time in-house citizen data is seamlessly integrated in the proposed architecture through the use of open prosumer data interfaces transformed to a common format and managed securely. EDDIE’s Administrative Interface for In-house Data Access (AIIDA) targets to integrate data from different behind-the-main-meter environments and allows to share that data through an online consent-based mechanism. Edge computing patterns are utilized to provide users insights into their local data, and act efficiently as a data provider to the outside on a higher level under the full control of the user.
