Expected Outcome:

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

  • Availability of generative Artificial Intelligence (AI) tools for electricity system operators, energy service providers, and households and energy communities to enhance digital and green transformation in energy, mobility, and buildings;
  • Implementation of decentralised IT solutions based on generative AI to support local grid optimisation, thereby increasing the uptake of renewable energy sources, electric vehicles, and electrification of household and industrial demand at the distribution level;
  • Increased reliability, resilience, security, and energy efficiency of the energy system through advanced AI and digital tools;
  • Enhanced knowledge for modernising and operating energy networks, integrating digital services, renewables, and electrification through the use of cutting-edge AI technologies;
  • Development of smarter demand-side tools for industries and consumers, leveraging AI to optimise energy production and consumption.

Scope:

To achieve the Green Deal objectives for 2030 and 2050, substantial investments are required in a smart and digitally enabled energy system capable of integrating higher shares of renewable energy and electrification of demand and electricity storage. This encompasses various sectors such as transport (notably electric vehicles), industry (heating and hydrogen production) and residential heating.

Effective smart planning, operation and control of the electricity grid and numerous distributed devices – including smart electricity meters, smart bi-directional charging networks for electric vehicles, and smart building platforms – are essential. These efforts must be underpinned by markets for flexibility and demand response, along with seamless data exchange between actors and devices.

On-going innovation in the energy data space, smart Internet of Things (IoT) solutions, and digital twins for energy systems, coupled with energy price and market considerations, provide the foundation for advanced energy system intelligence. This intelligence will be further enhanced by leveraging generative artificial intelligence and the emerging AI Factories[1].

The scope is to develop and pilot prototypes of a generative AI-powered digital spine[2] that enhances the digitalisation and decarbonisation of the EU energy system.

The overall scope is the development of a prototype of an automated, AI-powered, software-defined smart energy system leveraging and further developing existing (open-source) digital solutions of lower TRLs developed in EU and national research, innovation- and deployment-programmes, as well as AI algorithms and tools provided by the AI Factories, namely to:

  • Develop and test the potential for generative AI to develop apps/programmes for local system optimisation and for system planning and operation;
  • Develop and test generative AI that can identify sources of flexibility and provide solutions for interoperability and data exchange to enable decentralised optimisation of distributed assets. This includes the integration with various data sources and sectors, such as mobility, to promote decentralisation, energy-efficiency, and cost-efficiency and to enable interoperability across different parts of the energy system;
  • Explore the potential of generative AI for system optimisation through scenario generation, simulation, and time series forecasting, while also developing optimisation tools for both supply-side and demand-side management using forecasts and data for renewable energy, transmission assets, storage, and energy-saving applications for consumers;
  • Propose tools and control systems to apply generative AI solutions developed in a high-risk use-case (as defined in the AI act).

The developed solutions should be dynamic, flexible, offering reconfigurable automated management, control and data exchange to ensure seamless operations across decentralised a setting.

Projects are expected to:

  • Demonstrate AI-powered energy services, tools for power system planning and operation, and smart grid functionalities, such as flexibility, and electric vehicle (EV) charging as well as possibly transmission system operation across at least three EU member states and/or associated countries to enhance demand flexibility and drive innovative capabilities for decarbonisation and energy efficiency;
  • Indicate which generative AI basic tools, including available tools from the AI Factories, will be used and demonstrate how energy sector users will be involved in the development and the testing (and possible uptake) of the generative AI tools by the project;
  • Indicate what types of assets and what data sources will be used and involved in the project;
  • Involve both traditional energy stakeholders and new entrants, such as energy service companies, aggregators, digital infrastructure providers, system integrators, energy asset manufacturers, energy communities, and active consumers;
  • Leverage relevant European and international standards and technical specifications, and actively engage with standards development organisations;
  • Contribute to the BRIDGE initiative[3], actively participate in its activities;
  • Make use of the AI Factories and solutions, open-source where relevant, building on developments in previous Horizon Europe projects, particularly those related to flexibility markets and data exchange, Internet of Things and edge-cloud computing, adhering to relevant standards and engaging with standards development organisations to further develop these standards;
  • Demonstrate how the new solutions can be integrated into and/or replace (parts of) existing legacy systems, including (for projects that focus on DSOs) demonstrate how the new solutions can integrate core functions of grid operations including SCADA systems functionality;
  • Jointly provide a diverse set of applications of generative AI.

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

[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.
