The Trans-European Networks (TENs) – large, infrastructure networks that enable essential services and efficient connections between national networks – are jointly funded by the European Union and the Member States. Financial support from the EU serves as a catalyst, with the Member States providing the bulk of the financing. The financing of the TENs can be complemented by Structural Fund assistance, aid from the European Investment Bank (EIB) or contributions from the private sector. A major reform was introduced across the TENs with the establishment of the Connecting Europe Facility (CEF) in 2013, renewed in 2021. Source : © European Union, 2026 - EP Read more
