European (energy) data exchange reference architecture 3.0 (July 2023)

This report has been written by the Data Management Working Group.

It is the third version of Data Exchange Reference Architecture – DERA 3.0. BRIDGE report on energy data exchange reference architecture aims at contributing to the discussion and practical steps towards truly interoperable and business process agnostic data exchange arrangements on European scale both inside energy domain and across different domains


Exploration of citizen engagement methodologies in European R&I projects 3.0


Exploration of citizen engagement methodologies in European R&I projects 3.0 (June 2023)

The report has been written by the Consumer and Citizen Engagement Working Group (CCE WG).
It aims at creating a structured understanding of the role and methodologies of stakeholder engagement activities in European R&I projects. During the last Work Plan period (2022-2023), sub-groups got activated according to the conclusions from the last CCE WG Report 2022 the interest and will of BRIDGE project members participating in the WG CCE CCE and the consumers-related chapter of the Digitalisation of Energy Action Plan (DoEP). The latter reads “the European Commission will ensure that key R&I projects work together to identify, by mid-2023, strategies to engage consumers in the design and use of accessible and affordable digital tools and to identify indicators to assess engagement over time.”. Based on these premises, during the 2022 General Assembly, the CCE WG collectively planned to work on the following specific topics and actions during the 2022-2023 period, to respond to the needs and gaps identified in previous years and in the DoEP. To meet these goals, three sub-groups were structured under the Working Group. The structure, scope and focus of these sub-groups is detailed in the table below. The work carried out in the Working Group has been identified as an action delivered under the Action Plan on the Digitalisation of the Energy System.



Reference framework


Reference Framework 1.0 (June 2023)


This report has been produced by the Data Management Working Group.

Initially, the topic of “Interoperability of flexibility assets” was discussed and its scope defined during the BRIDGE General Assembly held on March 11th and 12th 2020 in Brussels. A first report on this topic has been published in April 2021, including a Reference Framework made of 3 Generic Business Processes (GBPs) and performing an interoperability analysis over 10 use-cases from 4 projects. Then, the Reference Framework has been extended to add 2 new GBPs and propose a first version of the Settlement subprocess. This second version of the Reference Framework was detailed in the “Interoperability of flexibility assets” report version 2.0 completed in June 2022, together with an interoperability analysis based on 36 use-cases from 14 projects.

Following the BRIDGE General Assembly of March 2022, it was decided to focus the activities on the further development of the Reference Framework, in particular:

  • To refine the existing GBPs based on the feedback from new projects;
  • To extend the Reference Framework to include new GBPs beyond flexibility;
  • To improve the Settlement subprocess based on the BRIDGE projects that are effectively implementing settlement.

This report presents an update of the Reference Framework, now describing 7 Generic Business Processes and also detailing the Settlement subprocess. It also highlights 3 main findings and recommendations: Consistency with existing standards and on-going initiatives: activities similar to the Reference Framework are performed in parallel to BRIDGE activities, in particular in IEC with 62913 series and in SGTF EG1 with a set of Implementing Acts for the Electricity Directive Article 24. Cooperation with these initiatives should be established to ensure consistency. Expectations and benefits from the Generic Business Processes: seven GBPs are now defined, covering flexiblity, energy monitoring and P2P trading.

The expectations from the BRIDGE projects and potential benefits should be studied to increase the impact of the Reference Framework. Further understanding of implementing the Settlement sub-process: the Settlement sub-process has been compared with its effective implementation in five on-going projects. Barriers and challenges should be identified and guidelines provided to ease the implementation of settlement in future projects.


Interoperability of home appliances


Interoperability of home appliances Report 2022-2023 (May 2023)


This is the initial BRIDGE Report by the Data Management Working Group on interoperability of home appliances.

It aims at providing a common view on the issue as well as at showing the first results from investigating the current state of affairs on this aspect within the BRIDGE projects. In the area of energy flexibility in residential buildings the home appliances constitute to the lowest, but probably one of the most important layers of the system. These appliances are indeed providing the flexibility. The success of the energy management solutions, like algorithms or systems, is highly related to the capabilities of the home appliances, as well as the ability to approach and exploit these capabilities. In that respect, a broader range of appliances providing flexibility and a common way to control these, allows wider deployment of energy management systems and increases the available flexibility of the energy systems


Energy Market Design and Flexibility


Regulations Working Group: Energy Market Design and Flexibility (Annual Report 2022) (May 2023)


The BRIDGE Regulatory Working Group fosters knowledge sharing among HEU and H2020 projects affected by or addressing different regulatory aspects in the Energy domain. In the last years, several topics have been addressed, resulting in most cases on specific reports that can be shared not only within the BRIDGE community but with a larger audience. The BRIDGE Regulatory working group is currently composed of 63 projects.


Investigation of Relationship of Use Cases and Cross-domain Business Models


Investigation of relationship of use cases and cross-domain business models. Report on topic 1 (September 2022)

The BRIDGE Business Models Working Group (BM WG) was relaunched following the 2021 BRIDGE General Assembly and started the work on 27.09.2021. The projects participating were grouped into three tasks. Task 1 aimed to zoom into concrete business models, related barriers to realize them and trend that may impact them. Task 2 investigated best practice for use cases monitoring and impact analysis and the role of Key Performance Indicators. Task 3 complemented and validated Task 1 and Task 2 activities with the help of a questionnaire to all participating projects. The work in the Tasks resulted in the present report that was discussed in a dedicated session at the BRIDGE general assembly on the 23.03.2022. The report consists of three main chapters, as prepared by the corresponding Task teams.


Exploration of citizen engagement methodologies in European R&I projects 2.0


Consumer & Citizen Engagement Working Group: Exploration of citizen engagement methodologies in European R&I projects (May 2022)


The report, prepared by the Consumer & citizen engagement working group in 2022, describes the development of the working group's activities, based on the 2020-2022 work plan, with the ultimate goal of creating a structured, cross-cutting understanding of the role and methodologies of engagement in European R&I projects.
