Projects of Common Interest (PCI) are important cross-border infrastructure projects that contribute to the integration of the energy networks of European countries. For a project to be classified as a PCI, it must lead to a very positive outcome, assessed through a cost-benefit analysis, in the energy markets of at least two Member States of the European Union. The aim of these projects is to contribute to the implementation of the EU’s energy and climate policy for affordable, safe, and sustainable energy in line with the long-term objectives of decarbonization of the EU economies in accordance with the Treaty of Paris.
