Call content
short description
As Europe progresses towards sustainable energy, high-voltage direct current (HVDC) systems are vital for the efficient transmission of renewable energy. To optimize these systems, challenges like component size, reliability, affordability, interoperability, supply chain resilience and life-cycle environmental impact of critical HVDC equipment must be addressed.
Call objectives
Projects must address all the following items:
- Investigate and develop primary equipment suitable for multi-terminal HVDC grids, that are small size, lightweight, environment-friendly (e.g. SF6 free, lead free), affordable and reliable, such as mechanical or hybrid (mechanical and solid-state) circuit breakers, fault current limiters, superconducting or conventional cables, conversion of high voltage alternating current (HVAC) overhead lines to HVDC ...
- Equipment affordability and interoperability are expected to be sought pragmatically, for example through modularisation, standardisation, focus on key functionalities and performances, size reduction, use of new components or new materials, …
- Conduct a comprehensive techno-economic assessment of the system integration of these technologies into multi-terminal HVDC systems.
- Test, validate performances in representative conditions, in relevant or operational environment".
- Contribute to standardisation bodies.

Expected effects and impacts
To ensure the developed equipment is fit for use and interoperable, the consortium must include at least two equipment or system manufacturers, at least two transmission system operator (TSO) and at least two research centres.
The range of expected EU contributions specified in the table above is broad, because the types of equipment within the scope of the topic have by nature very different costs; therefore, the project costs and the expected EU contribution must be justified according to the scope of the project.
Expected results
Project results are expected to contribute to all the following expected outcomes:
- The expansion of High Voltage Direct Current (HVDC) infrastructure across Europe is facilitated and supports the EU's energy transition through more performant, sustainable and affordable HVDC equipment that ensure higher grid reliability and stability.
- Enhanced affordability and interoperability of HVDC grid equipment.
- Enhanced reliability and stability of HVDC Grid, through developing advanced protection and control equipment.
- Enhanced environmental sustainability of HVDC equipment, by reducing their carbon footprint and enhancing their sustainability, e.g. through the development of SF6-free alternatives.

Legal entities which are established in countries not listed above will be eligible for funding if provided for in the specific call/topic conditions, or if their participation is considered essential for implementing the action by the granting authority.
Any legal entity, regardless of its place of establishment, including legal entities from non associated third countries or international organisations (including international European research organisations) is eligible to participate (whether it is eligible for funding or not), provided that the conditions laid down in the Horizon Europe Regulation have been met, along with any other conditions laid down in the specific call/topic.
A ‘legal entity’ means any natural or legal person created and recognised as such under national law, EU law or international law, which has legal personality and which may, acting in its own name, exercise rights and be subject to obligations, or an entity without legal personality.
Unless otherwise provided for in the specific call/topic conditions, only legal entities forming a consortium are eligible to participate in actions provided that the consortium includes, as beneficiaries, three legal entities independent from each other and each established in a different country as follows:
- at least one independent legal entity established in a Member State; and
- at least two other independent legal entities, each established in different Member States or Associated Countries.
As affiliated entities do not sign the grant agreement, they do not count towards the minimum eligibility criteria for consortium composition (if any).
If projects use satellite-based earth observation, positioning, navigation and/or related timing data and services, beneficiaries must make use of Copernicus and/or Galileo/EGNOS (other data and services may additionally be used).
other eligibility criteria
Specific cases
Affiliated entities — Affiliated entities (i.e. entities with a legal or capital link to a beneficiary which participate in the action with similar rights and obligations to the beneficiaries, but which do not sign the grant agreement and therefore do not become beneficiaries themselves) are allowed, if they are eligible for participation and funding.
Associated partners — Associated partners (i.e. entities which participate in the action without signing the grant agreement, and without the right to charge costs or claim contributions) are allowed, subject to any specific call/topic conditions.
Entities without legal personality — Entities which do not have legal personality under their national law may exceptionally participate, provided that their representatives have the capacity to undertake legal obligations on their behalf, and offer guarantees to protect the EU’s financial interests equivalent to those offered by legal persons.
EU bodies — Legal entities created under EU law including decentralised agencies may be part of the consortium, unless provided for otherwise in their basic act.
Joint Research Centre (‘JRC’) — Where provided for in the specific call/topic conditions, applicants may include in their proposals the possible contribution of the JRC, but the JRC will not participate in the preparation and submission of the proposal. Applicants will indicate the contribution that the JRC could bring to the project based on the scope of the topic text. After the evaluation process, the JRC and the consortium selected for funding may come to an agreement on the specific terms of the participation of the JRC. If an agreement is found, the JRC may accede to the grant agreement as beneficiary requesting zero funding or participate as an associated partner, and would accede to the consortium as a member.
Associations and interest groupings — Entities composed of members (e.g. European research infrastructure consortia (ERICs)) may participate as ‘sole beneficiaries’ or ‘beneficiaries without legal personality’. However, if the action is in practice implemented by the individual members, those members should also participate either as beneficiaries or as affiliated entities (otherwise their costs will NOT be eligible).
EU restrictive measures — Entities subject to EU restrictive measures under Article 29 of the Treaty on the European Union (TEU) and Article 215 of the Treaty on the Functioning of the EU (TFEU) as well as Article 75 TFEU, are not eligible to participate in any capacity, including as beneficiaries, affiliated entities, associated partners, third parties giving in-kind contributions, subcontractors or recipients of financial support to third parties (if any).
Legal entities established in Russia, Belarus, or in non-government controlled territories of Ukraine — Given the illegal invasion of Ukraine by Russia and the involvement of Belarus, there is currently no appropriate context allowing the implementation of the actions foreseen in this programme with legal entities established in Russia, Belarus, or in non-government controlled territories of Ukraine. Therefore, even where such entities are not subject to EU restrictive measures, such legal entities are not eligible to participate in any capacity. This includes participation as beneficiaries, affiliated entities, associated partners, third parties giving in-kind contributions, subcontractors or recipients of financial support to third parties (if any). Exceptions may be granted on a case-by-case basis for justified reasons.
With specific regard to measures addressed to Russia, following the adoption of the Council Regulation (EU) 2024/1745 of 24 June 2024 (amending Council Regulation (EU) No 833/2014 of 31 July 2014) concerning restrictive measures in view of Russia’s actions destabilising the situation in Ukraine, legal entities established outside Russia whose proprietary rights are directly or indirectly owned for more than 50% by a legal person, entity or body established in Russia are also not eligible to participate in any capacity.
Measures for the protection of the Union budget against breaches of the principles of the rule of law in Hungary — Following the Council Implementing Decision (EU) 2022/2506, as of 16 December 2022, no legal commitments can be entered into with Hungarian public interest trusts established under the Hungarian Act IX of 2021 or any entity they maintain. Affected entities may continue to apply to calls for proposals and can participate without receiving EU funding, as associated partners, if allowed by the call conditions. However, as long as the Council measures are not lifted, such entities are not eligible to participate in any funded role (beneficiaries, affiliated entities, subcontractors, recipients of financial support to third parties, etc.). In the case of multi-beneficiary grant calls, applicants will be invited to remove or replace that entity in any funded role and/or to change its status into associated partner. Tasks and budget may be redistributed accordingly.
