Description
Project results are expected to contribute to all the following expected outcomes:
- Improved preparedness of the electricity grids to support the EU's binding target for 2030 of minimum 42.5% renewables in gross final energy consumption, with the aspiration to reach 45% by 2030 and full decarbonisation by 2050;
- Increased resilience and flexibility of electricity grids, which are able to better manage high shares of variable renewable energy systems (RES);
- Transmission system operators (TSO) and Distribution system operators (DSO) develop and use modern procedures and techniques for maintaining grid stability and secure operation;
- Seamless integration of power electronics-interfaced devices (PEID) in modern grids.
Projects are expected to address all the following items:
- Develop new and improved knowledge and insights into the synthetic inertia, frequency control, very fast voltage support, and overall support to the system stability offered by grid-forming inverters (GFIs). Develop and/or update relevant models and simulation tools;
- Develop and demonstrate innovative grid control and grid-forming solutions that leverage the capabilities of GFIs with the view to enable mass deployment of GFIs;
- Address use cases for both transmission- and distribution-level grids, ranging from applications used in residential and commercial domains up to the use in large RES generators (PV or wind) and grid-scale battery storage systems. They could also consider solutions that include LVDC microgrids that are connected to the main AC grids;
- Take a system-wise approach, including control strategies that can effectively encompass wider areas;
- Develop interoperability between different solutions and products from different GFI manufacturers. Devise standardised approaches through the use of hardware in the loop and advanced simulation models for GFIs;
- Leverage modern solutions, including digital twins and artificial intelligence. Use and/or develop, to the greatest extent possible, open-source software solutions and or software modules.
- Develop a manual and propose best practices on this matter to be used by TSOs and DSOs. Propose sets of standardised technical requirements for GFIs, test models and procedures for verification of compliance (for the use of TSOs and DSOs) Identify remaining gaps and further needs for research and development. Suggest market conditions and/or opportunities that would incentivise the deployment at scale of GFIs.
The demonstration, test and validation of the activities must be carried out in at least two pilots in different EU Member States or Associated Countries. The pilots are expected to address diverse solutions (including voltage levels and geographical landscapes).
Projects are expected to include at least: one electricity TSO, two DSOs, one provider of technology that includes GFIs, one RES-based energy producer, and one university and/or research organisation.
Additionally, collaboration is encouraged with:
- one or more suppliers of GFIs, with the aim to cover the whole range of products intended to be connected to both transmission and distribution voltage levels;
- at least one grid-scale battery storage system operator
- at least one aggregator that manages distributed energy resources that include GFIs.
This collaboration (minimum number of entities) is sought per project in total and does not necessarily apply per each pilot in particular.
Selected projects are expected to contribute to the BRIDGE initiative[1] and actively participate in its activities.
Proposals are encouraged to consider, where relevant, services offered by European research infrastructures[2], as well as related projects offering access to research infrastructures in the electricity grid domain- particularly RISEnergy[3].
International cooperation is encouraged, especially with Mediterranean countries other than the EU and with Latin America and the Caribbean.

Destination & Scope
This Destination includes activities targeting a sustainable, secure and competitive energy supply. In line with the scope of cluster 5, this includes activities in the areas of renewable energy; energy system, grids and storage; as well as Carbon Capture, Utilisation and Storage (CCUS).
This Destination contributes directly to the Strategic Plan’s Key Strategic Orientations ‘Green transition’, ‘Digital transition’ and ‘A more resilient, competitive, inclusive and democratic Europe’.
In line with the Strategic Plan, the overall expected impact of this Destination is to contribute to the ‘Ensuring more sustainable, secure and competitive energy supply through solutions for smart energy systems based on renewable energy solutions’.
This destination contributes to the activities of the Strategic Energy Technology Plan (SET Plan) and its implementation working groups.
The main impacts to be generated by topics under this Destination are:
Renewable energy
- Energy producers have access to efficient and competitive European renewable energy and renewable fuel technologies with a solid knowledge base and are able to deploy them to enhance the EU’s energy security and reach its climate neutrality objectives, in a sustainable way in environmental (e.g., biodiversity, multiple uses of land and water, natural resources, pollution) and socioeconomic terms, and in line with the Sustainable Development Goals.
- Technology providers have access to European, competitive, resilient, reliable, sustainable, and affordable value chains of renewable energy and renewable fuel technologies including emerging ones, and with strong export potential to supply both the EU internal and global markets. They benefit also from circular renewable energy technologies that are safe and sustainable by design with reduced and diversified external dependence on critical raw materials[1].
- Economic sectors benefit from better integration of renewable energy and renewable fuel-based solutions that are, among others, competitive, cost-effective, efficient, flexible, reliable, and sustainable. Such integration is facilitated through digitalisation and integration of artificial intelligence of renewable energy technologies that provide network stability and reliability.
- European industries benefit from a reinforced export potential of renewable energy and renewable fuel technologies, also through international partnerships, and become more competitive in innovative renewable energy technologies in Europe and globally.
- European researchers benefit from a stronger community and from a reinforced scientific basis on renewable energy and renewable fuel technologies including emerging ones, also through international collaborations.
- European citizens have access to an energy market that is fair and equitable, more resilient, uses all different types of local renewable energy resources, and is less dependent on fossil fuels imports. Citizens experience less fuel and energy poverty, and also benefit from new employment and upskilling opportunities. Local communities benefit from a more decentralized, affordable, and secure energy system and from multiple uses of land and water.
Energy systems, grids and storage
- R&I actions will support the just digital and green transformation of the energy system through advanced solutions for accelerating the energy systems integration and decarbonisation. The developed clean, sustainable solutions will contribute to making the energy system work better for actors and supply more reliable, resilient and secure energy – even under increasingly more frequent extreme climate events.
- The solutions developed will contribute to increase flexibility and grid hosting capacity for renewables through optimizing cross sector integration and grid scale storage as well as cover off-grid situations. They will improve the preparedness of the electricity system to support the EU's binding target for 2030 of minimum of 42.5% renewables in the gross final energy consumption (with the aspiration to reach 45%), and full decarbonisation by 2050. They will enable further electrification of demand and will enhance the competitiveness of the European value chain, reduce pressure on resources (also by making technologies ‘circular by design’) and decrease dependencies. Such solutions would also enable a better EU resilience to climate risks.
- The solutions will improve consumer awareness and engagement in the energy transition, via innovative offers and services (e.g. demand response, energy communities) and will target different types of consumers, including “hard to reach” population groups (such as energy poor or low-income households). This will result in increased trust in, and uptake of the new products and services entering the energy system.
Carbon capture, use and storage (CCUS) and carbon dioxide removal (CDR)
- Accelerated deployment of carbon capture, use and storage (CCUS) as a CO2 emission mitigation option in electricity generation and/or in industry applications, as well as carbon dioxide removal for negative emissions.
