Scope
Expected Outcome: Projects are expected to contribute to all the following expected outcomes: Effective and innovative methods for gathering, sharing and using large data sets in energy applications for the purpose of training AI models while ensuring privacy and security. Advanced and - wherever possible - open-source AI foundation models to support the digitalisation of the energy system, through improved grid observability, forecasting of supply and demand, advanced storage and renewables integration, demand side flexibility and energy efficiency. Enhanced cooperation, knowledge sharing and interoperability among energy system actors for secure and seamless data exchange. Advanced methodologies for AI model development ensuring that the results are FAIR (Findable, Accessible, Interoperable, Reusable) beyond the project ending, open source and accommodating for technology evolution. Scope: The quality of AI models depends strongly on the amount, quality, and representativeness of the data used for their training. Projects are expected to focus on developing, training and testing AI foundation models, using extensive data sets to accelerate the energy transition in key focus areas of the energy sector. Projects are expected to: Building on the results of previously funded projects on the Common European energy data space [1] as well as the ongoing work within the Data 4 Energy expert group, projects are expected to demonstrate innovative methods and data governance strategies for sharing data among various energy actors. Projects are expected to demonstrate that they have access to large relevant datasets at the time of submitting the proposal. Projects are expected to develop innovative strategies for sharing data in an effective, secure and transparent way to support the development of AI foundation models. An indicative non exhaustive list of strategies that can be explored is the use of data space connectors or federated training of models to allow the integration of confidential data; the creation of synthetic data as an intermediate step to fill data gaps or improve the quality of the data could also be explored. Projects could also explore other innovative data sharing strategies, such as an ‘AI gym’. The data governance strategies that will be developed in the project should be designed in a way to be scalable and operational even after the end of the project. Projects are expected to develop foundation models tailored for the energy sector, addressing at least one -or more- of the following use cases: planning and operation of electricity grids…
Get told when something changes
Most institutions find out about a call with three weeks left. We write when something opens, moves or closes that fits what you work on, with the deadline, the fit and the funder's own exclusion clauses quoted. Nothing in a quiet week. Free, and one click to leave.
Starting from the programme you are reading: Horizon Europe (HORIZON) — change it below if you like.
Leave the second box empty and you get whatever opened or changed recently, closing soonest. Fill it in and it ranks against your words instead: that is the difference between a list and a shortlist.
Scientific Network Management will send you the current list for these terms, and after that only what changes: a call that opens, a deadline that shifts, a clause that rules you out. Nothing is sent when nothing has moved. One click to stop, in every message.
One confirmation email and nothing else until you click it. No tracking pixels, no sharing, one click to unsubscribe.
Of every 100 Horizon Europe proposals
A funding strategy reads your institution's own published record against the calls that are open, and says in writing which are worth the year and which to decline, with the reason for each.
Scientific Network Management, the grant-writing practice behind this radar: 13 years of EU-funded research projects, and a founder who has served as Key Expert and Team Leader on two EU-funded technical assistance contracts establishing biotechnology centres in Türkiye.

No obligation, and nothing here is conditional on using us: searching the calls stays free and asks for nothing either way.
