This Horizon Europe call is focused on developing innovative solutions using generative AI to enhance the EU's energy system. It aims to create a smart, efficient, and decarbonised energy grid by leveraging AI to optimise energy production, distribution, and consumption. The call encourages projects that can demonstrate AI-powered tools and services, integrate new solutions into existing systems, and involve a diverse range of stakeholders. Ultimately, this initiative seeks to contribute to the EU's Green Deal objectives by promoting the use of AI in transforming the energy sector.

Eligible Applicant Types: The eligible applicant types are not explicitly stated in the provided text. However, based on the nature of Horizon Europe projects and the call for proposals, eligible applicants could include universities, research institutes, SMEs, large enterprises, and other relevant organizations involved in energy, AI, and digital technologies. The call also mentions involving 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, suggesting a broad range of eligible entities.

Funding Type: The primary financial mechanism is a grant, specifically a HORIZON Action Grant Budget-Based [HORIZON-AG], as indicated by the "Type of MGA" (Model Grant Agreement). The call also includes HORIZON Innovation Actions (HORIZON-IA), HORIZON Research and Innovation Actions (HORIZON-RIA), HORIZON Pre-commercial Procurement (HORIZON-PCP), and HORIZON Coordination and Support Actions (HORIZON-CSA).

Consortium Requirement: The text does not explicitly state whether a consortium is required. However, the project descriptions often involve demonstrating solutions across at least three EU member states and/or associated countries and involving both traditional energy stakeholders and new entrants. This suggests that a consortium of multiple applicants is highly encouraged, if not required, to meet the scope and expected outcomes of the call. Partner search announcements are also available, indicating that applicants may need to form consortia.

Beneficiary Scope (Geographic Eligibility): The primary geographic eligibility appears to be EU member states and/or associated countries. The call mentions demonstrating solutions across at least three EU member states and/or associated countries. The text also mentions that a number of non-EU/non-Associated Countries that are not automatically eligible for funding have made specific provisions for making funding available for their participants in Horizon Europe projects.

Target Sector: The program targets several interconnected sectors, including: Energy (smart and digitally enabled energy systems, electricity grids, renewable energy integration, electricity storage), ICT (Artificial Intelligence, Internet of Things, digital twins, data exchange), Transport (electric vehicles, charging networks), Buildings (smart building platforms, residential heating), Climate (decarbonisation, energy efficiency), Innovation (AI-powered energy services, smart grid functionalities), and Digital (digital transformation, digital spine).

Mentioned Countries: The text refers to "EU member states and/or associated countries" without explicitly listing specific countries. It also mentions "non-EU/non-Associated Countries" without specifying which ones. Therefore, the geographic focus is primarily on the EU and associated countries, with potential participation from other countries under specific provisions.

Project Stage: The expected maturity of the project is at the development and piloting stage, specifically to "develop and pilot prototypes of a generative AI-powered digital spine." The call also mentions leveraging and further developing existing (open-source) digital solutions of lower TRLs (Technology Readiness Levels), suggesting that projects should build upon existing research and innovation.

Funding Amount: The funding amounts vary depending on the specific action type (HORIZON-IA, HORIZON-RIA, HORIZON-PCP, HORIZON-CSA) and topic. The budget overview provides a detailed breakdown of the budget allocated to each topic, ranging from €6,000,000 to €33,000,000. The indicative number of grants for each topic also varies, ranging from 1 to 3. For example, HORIZON-CL5-2026-02-D3-19 has a budget of €16,000,000 and an indicative number of 2 grants.

Application Type: The application type is an open call with a single-stage submission process. The planned opening date is 16 September 2025, and the deadline date is 17 February 2026.

Nature of Support: The beneficiaries will receive money in the form of grants to support their research, development, and innovation activities. The funding is intended to cover eligible costs associated with the project, as defined in the Horizon Europe Model Grant Agreement.

Application Stages: The application process consists of a single stage, as indicated by the "Deadline model: single-stage." This means that applicants must submit a complete proposal by the deadline date.

Success Rates: The success rates are not explicitly mentioned in the text. However, the indicative number of grants for each topic provides some insight into the potential success rate. For example, if a topic has a budget of €15,000,000 and an indicative number of 3 grants, the success rate is likely to be relatively low, as Horizon Europe calls typically attract a large number of proposals.

Co-funding Requirement: The text does not explicitly mention a co-funding requirement. However, Horizon Europe grants typically fund a percentage of the total eligible costs, meaning that beneficiaries may need to secure additional funding from other sources to cover the remaining costs.

Summary: This Horizon Europe call focuses on "Innovative solutions for a generative AI-powered digital spine of the EU energy system." It aims to support projects that develop and pilot prototypes of AI-powered solutions to enhance the digitalisation and decarbonisation of the EU energy system. The call seeks to integrate higher shares of renewable energy, improve grid management, and optimise energy consumption across various sectors, including transport, industry, and buildings. The projects should leverage generative AI, IoT solutions, and digital twins to create dynamic, flexible, and automated smart energy systems. Eligible applicants include a wide range of stakeholders from EU member states and associated countries, with a strong emphasis on collaboration and the involvement of both traditional energy players and new entrants. The funding is provided through Horizon Innovation Actions (IA), Research and Innovation Actions (RIA), Pre-commercial Procurement (PCP), and Coordination and Support Actions (CSA), with budgets ranging from €6 million to €33 million per topic. The application process is a single-stage open call with a deadline of 17 February 2026. The expected outcomes include the availability of AI tools for energy stakeholders, the implementation of decentralised IT solutions for local grid optimisation, and the increased reliability and energy efficiency of the energy system.
