Projects of Common Interest (PCIs) are key energy infrastructure projects that are essential for completing the European internal energy market and contribute to climate change mitigation, in particular to achieving the Union’s energy and climate targets for 2030 and its objective of climate neutrality by 2050 at the latest. They also contribute to ensuring the interconnection of energy networks, energy security, market and system integration, and competition benefiting all Member States, as well as to the affordability of energy.
Projects of Mutual Interest (PMIs) are key energy infrastructure projects that the Union promotes in cooperation with third countries.
