The EU funds delivered through this financial instrument are intended for supporting the development of high-performing, sustainable and efficiently interconnected trans-European transport, energy and digital networks and for filling the missing links between these three areas.

Regulation (EU) No 1316/2013 of the European Parliament and of the Council establishing the Connecting Europe Facility provides for the funding rates and the conditions under which a project is eligible for funding. It distinguishes between grants and innovative financial instruments (e.g. guarantees) that serve as efficient leverage for attracting resources from private investors.
