Call content
short description
The objective of this call is to support the deployment or significant upgrade of backbone networks – in particular submarine cables but also terrestrial backbone networks and satellite infrastructure – that address risks, vulnerabilities and dependencies in the EU backbone infrastructure.
Call objectives
Proposals must meet one of the following conditions:
- connect at least two Member States. In the case of terrestrial backbones, only cross-border segments necessary to interconnect national backbones will be funded;
- connect a Member State with one or several of its islands, outermost regions, or overseas countries and territories;
- connect one or several Member States and third countries, including accession and neighbourhood countries, directly, or indirectly via other cable infrastructures linked to the Union.
Proposals must concern the deployment or significant upgrade of a backbone network that addresses a market failure in at least one of the following scenarios:
- The project concerns a route where there is a lack of redundancy; and/or
- The project concerns a route where existing backbone infrastructures cannot satisfy current or expected demand; and/or
- The project concerns a route subject to regulation because it is not considered competitive by the competent national regulatory authority. This scenario only applies to projects where the infrastructure will contribute to increase competition in the concerned route and will offer wholesale access to third parties under fair and non-discriminatory conditions.
For the purpose of assessing scenarios 1) and 2), only EU-controlled infrastructures are taken into account.
In the case of submarine cables, proposals should specify whether they contribute to the resilience and security of submarine cables connectivity in CPEI Areas 1-13 (except Areas 8 and 10), and in particular Areas 1-7 from the CPEI list published in February 2026, as projects contributing to such areas will be scored positively under the evaluation criterion “Priority and Urgency”.
The proposed project should be self-standing by providing connectivity to users. Projects that will require the deployment of an additional segment to meet this requirement could only be taken into account if the proposal includes a commitment to complete the deployment and a sound financing plan for the entire network (including the above-mentioned additional segment). The evaluation of a project will take into account, as a positive element, its contribution to a wider objective (e.g. completing a cable ring or system can bring additional benefits to those intrinsically associated to the project).
Applicants may choose the technological solution that they consider more suitable, which may include submarine cables systems, terrestrial backbone networks and satellite infrastructure. Applicants should justify their technological choice and should also explain how they will ensure the supply chain security, as regards availability of components, technologies, systems and knowhow required in the planning, acquisition, construction, operation, maintenance and repair of the backbone infrastructure.

Expected effects and impacts
The expected impact of the supported project include:
- significantly improved security and resilience of the EU backbone networks;
- strengthened quality of connectivity within the Union as well as with third countries;
- capacity, security and resilience of the overall backbone network infrastructure benefit all EU end-users;
- benefits surpass those directly related to the individual supported projects and contribute to bridging the digital divide and ensuring widespread access to the Gigabit networks for all EU end-users and businesses.
Key performance indicators for this topic will include: i) the total length of the backbone, and ii) the additional (significant) transmission capacity created as a result of the projects supported by CEF. For submarine cables the number of fibre pairs, the current capacity per fibre pair, as well as the technology chosen and whether the system is repeated or unrepeated should be mentioned in the proposal, too.

Expected results
This Call encourages:
- the deployment of “smart” cable technologies, which can use the actual length of the cable by attaching sensors and/or by other probing techniques at the edge, to observe and monitor displacement and/or acoustic signals. Beneficiaries are expected to ensure the use of data gathered through such technologies with Regional Cable Hubs and/or authorised relevant stakeholders (e.g. the scientific and academic communities for environmental monitoring and civil protection purposes);
- the provision of wholesale access to third parties;
- the promoters of complementary projects to exploit possible synergies for instance, reusing or extending existing studies or works, sharing or upgrading capacities to fulfil the needs of the concerned stakeholders;
- the combination with funding from other EU programmes such as NDICI, ERDF or IPA III. In case of co-funding by EU programmes under shared management (including Cohesion Funds), State aid rules may apply (see section 10 of the Work Programme for detail).

other eligibility criteria
Specific cases and definitions
Exceptional funding — Entities from other countries (not listed above), namely entities established in third countries associated to the CEF Programme and entities established in third countries not associated to the CEF Programme are exceptionally eligible for projects of common interest, if the granting authority considers their participation essential for the implementation of the action, and on the condition that those entities provide security guarantees, approved, on the basis of national law, by the country in which they are established.
Legal entities that are established in EU Member States, but are not EU controlled, shall also be eligible to participate on the condition that they provide security guarantees, approved, on the basis of national law, by the EU Member State in which they are established.
In case the ownership control assessment concludes that an entity established in the EU is not controlled from an EU Member State, this entity will be notified of the outcome of the assessment and it shall be obliged to provide the security guarantee, approved, on the basis of national law, by the EU Member State in which it is established, within 30 working days of the receipt of the notification and at the latest before the signature of the Grant Agreement.
Please note that security guarantees are not required for EU controlled legal entities established in third countries associated to the CEF Programme.
Natural persons — Natural persons are NOT eligible (with the exception of self-employed persons, i.e. sole traders, where the company does not have legal personality separate from that of the natural person).
International organisations — International organisations are eligible. The rules on eligible countries do not apply to them.
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 for the protection of the EU financial interests equivalent to that offered by legal persons.
EU bodies — EU bodies (with the exception of the European Commission Joint Research Centre) can NOT be part of the consortium.
EU restrictive measures — Special rules apply for 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) and entities covered by Commission Guidelines No 2013/C 205/05). Such entities are not eligible to participate in any capacity, including as beneficiaries, affiliated entities, associated partners, subcontractors or recipients of financial support to third parties (if any).
EU conditionality measures - Following the Council Implementing Decision (EU) 2022/2506, as of 16th December 2022, no legal commitments (including the Grant Agreement itself as well as subcontracts, purchase contracts, financial support to third parties etc.) can be signed with Hungarian public interest trusts established under Hungarian Act IX of 2021 or any entity they maintain. Affected entities may continue to apply to calls for proposals. However, in case 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). In this case, co-applicants will be invited to remove or replace that entity and/or to change its status into associated partner. Tasks and budget may be redistributed accordingly”.

In the following exceptional cases, proposals may benefit from a higher grant amount, not exceeding EUR 60 000 000, in either or both of the following cases:
- proposals combining systems, still under development by different promoters, that achieve a greater geographical reach and avoid overlapping segments; applicants will have to demonstrate that earlier studies and works, developed or implemented separately, will be integrated in one single global project. In order to benefit from this higher grant amount, applicants will have to justify a greater impact (e.g. synergy leading to substantially higher geographical scale, etc.) and catalytic effect (e.g. synergy between different promoters resulting in substantial cost-efficiency gains).
- proposals whose scope is entirely and significantly contributing to one of the areas identified as CPEIs Stage 1 https://digital-strategy.ec.europa.eu/en/library/submarine-cable-security-toolbox-and-cable-projects-european-interest. In order to benefit from this higher grant amount, applicants will have to justify a greater EU priority and urgency (underpinning a specific CPEI priority area) as well as high levels of maturity and quality.
