Next generation distribution substation for increasing the system resilience -

Call text (as on F&T portal)

View on F&T portal

Expected Outcome:

Project results are expected to contribute to all of the following expected outcomes:

  • Improved observability, monitoring and control of the electricity distribution grids;
  • Optimised management (including maintenance) of the grids by system operators and improved system resilience (including withstanding natural hazards and cybersecurity incidents);
  • Grid operators integrate in their practices real-time decision-making. These could be assisted by artificial intelligence (AI) algorithms, if applicable;
  • A 'smart substation ecosystem’ is created that includes distribution system operators, technology/solution providers, integrators, application developers etc. This should cover both high-to-medium and medium-to-low voltage levels.

Scope:

Projects are expected to:

  • Demonstrate the integration of power electronics, intelligent electronic devices (IEDs), and software solutions in the distribution substations or in their proximity;
  • Demonstrate real-time monitoring and analysis of grid conditions (including power quality, voltage levels, grid component monitoring, and overall system performance) that allow operators to quickly identify and address any potential issues or disturbances, help to prevent outages and minimise the impact of service disruptions;
  • Consolidate data streams from otherwise dispersed sources to create unified visualisations and consolidated analytics that offer insights into the performance of distributions substations;
  • Develop the concept of a flexible and programmable electricity distribution grid in which the substation is a centre of intelligence that facilitates optimal power routing while ensuring the resilience of the electricity grid.

The demonstration, test and validation of the activities should be carried out in at least two pilots in different EU Member States and/or Associated Countries.

The projects should propose a set of best practices and recommendations on effective overarching principles and operational measures for: (i) building smart distribution substations, and (ii) integrating them into a more resilient, intelligent, and responsive distribution grid which is able to tackle disturbances and address net congestion.

Projects are expected to include at least five distribution system operators (DSOs) operating across different geographies and climate conditions. This total number of DSOs per project could be distributed across the different pilots of a particular project.

Additionally, collaboration is encouraged with the following entities:

  • at least two suppliers of technologies for smart power substations;
  • at least one TSO.

This collaboration (minimum number of entities) is sought per project in total and does not necessarily apply per each pilot in particular.

The selected projects are expected to contribute to the BRIDGE initiative[1], actively participate in its activities.

null

Activities are expected to achieve TRL 7-8 by the end of the project – see General Annex B. Activities may start at any TRL.

[1] Proposals with the same score were ranked according to the priority order procedure set out in the call conditions (for HE, in the General Annexes to the Work Programme or specific arrangements in the specific call/topic conditions).

To determine the ranking for ‘Innovation actions’, the score for ‘Impact’ is given a weight of 1.5.

[2] According to the specific condition of HORIZON-CL5-2026-02-D3-01, to ensure a balanced portfolio coverage, grants are awarded to proposals not only in order of ranking but at least also to one proposal that is the highest ranked within the area of liquid advanced biofuels and at least also to one proposal that is the highest ranked within the area of liquid renewable fuels of non-biological origin, provided that proposals attain all thresholds (and subject to available budget).

According to the specific condition of HORIZON-CL5-2026-02-D3-05, to ensure a balanced portfolio coverage, grants are awarded to proposals not only in order of ranking but at least also to one proposal that is the highest ranked within the area of concentrated solar power (CSP) and at least also to one proposal that is the highest ranked within the area of solar thermal heat and/or cold, provided that proposals attain all thresholds (and subject to available budget). Therefore, additional proposals are retained for funding to fulfil this condition.

According to the specific condition of HORIZON-CL5-2026-02-D3-08, to ensure a balanced portfolio coverage, grants are awarded to applications not only in order of ranking, but priority will be given to high-ranking proposals that ensure, collectively, the best coverage of the different European sea basins (Atlantic Ocean, Baltic Sea, Black Sea, North Sea and Mediterranean Sea), provided that the proposals attain all thresholds. Therefore, additional proposals are retained for funding to fulfil this condition.

According to the specific condition of HORIZON-CL5-2026-02-D3-14, to ensure a balanced portfolio coverage, grants are awarded to applications not only in order of ranking but at least also to one project that is the highest ranked within area 1., 2. or 3., provided that the applications attain all thresholds. Therefore, additional proposals are retained for funding to fulfil this condition.

According to the specific condition of HORIZON-CL5-2026-02-D3-24, to ensure a balanced portfolio coverage of both (i) point-source capture and (ii) direct air capture technologies, grants are awarded to not only in order of ranking but at least also to one proposal that is the highest ranked within each area, provided they attain all thresholds (and subject to available budget).

Summary of observer report:

The process was professionally organized and executed with rigor. It was fair, impartial, expertise-driven, and transparently documented at every step. Consensus Reports, the definitive outputs of the evaluation, consistently met high quality standards, closely aligned with the published and communicated guidance, and complied with all applicable rules. Panels were composed to ensure balanced expertise, and newly introduced Vice-Chairs facilitated discussions that were structured, respectful, and evidence-based. Divergent assessments were addressed through focused, criterion-by-criterion debate, and rationales were clearly recorded to ensure traceability.

Robust safeguards supported integrity and consistency. Conflict-of-interest declarations were systematically collected and enforced. Calibration briefings promoted a common understanding of scoring scales and evaluation criteria, enabling consistent judgments across proposals and panels. Quality control mechanisms, including cross-checks, effectively harmonized outcomes without compromising the independence of assessments. Confidentiality was maintained throughout. Access controls in the SEP system and teleconferencing platforms were appropriate, data handling was secure, and sensitive information was treated with due care.

Operationally, the evaluation benefited from clear timelines, timely support to evaluators, and a reliable digital infrastructure. The documentation was complete and accessible, and the SEP system provided full transparency over inputs and decisions. Overall, the exercise adhered to its core principle, namely impartiality, fairness, and confidentiality throughout. The resulting evaluation summary reports and ranking list are consistent, well-reasoned, and aligned with the guiding documents.

We recently informed the applicants about the evaluation results for their proposals.
