Deadline: 30-Jun-2026
The European Commission invites applications to support studies and preparatory actions for EU backbone connectivity infrastructure. Grants of up to €20,000,000 for works and €5,000,000 for studies (up to €60,000,000 in exceptional cases) aim to improve network quality, resilience, and integration while addressing vulnerabilities and dependencies in EU backbone systems.
What is the EU Backbone Connectivity Grant?
This initiative funds studies and preparatory actions to enhance the development of EU backbone networks, including Critical Project of European Interest (CPEI) networks. The programme supports early-stage activities that strengthen infrastructure planning, integration, and deployment.
Key Focus Areas Include:
- Improving quality and maturity of future EU backbone networks
- Supporting studies and preparatory works for deployment or significant upgrades
- Addressing risks, vulnerabilities, and dependencies in backbone infrastructure
- Facilitating integration of multiple systems into large-scale EU-wide projects
