Call content
short description
Studies related to the deployment/significant upgrade of backbone networks that address risks, vulnerabilities and dependencies in the EU backbone infrastructure.
Call objectives
Support will be given to studies for the deployment of backbone connectivity meeting one of the following conditions:
- connect at least two Member States. In the case of terrestrial backbones, only cross-border segments necessary to connect 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 should specify whether they contribute to the resilience and security of submarine cable 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 with such characteristics will be scored positively under the evaluation criterion ”Priority and Urgency”.

Expected effects and impacts
The expected impact of the supported project include improved quality and maturity of future EU backbone networks development, in particular CPEIs.
Expected results
The following activities can be funded:
- all preparatory work required prior to signing a contract with a supplier, such as marine ground surveys for submarine cables and the application for any required permits;
- studies for possible follow up/deployment of cable projects of European interest during the Multiannual Financial Framework 2028-2034 are also eligible.

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”.

The available call budget for two topics:
- CEF-DIG-2026-GATEWAYS-WORKS - Backbone connectivity for Digital Global Gateways – Works
- CEF-DIG-2026-GATEWAYS-STUDIES - Backbone connectivity for Digital Global Gateways - Studies
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.
