A high degree of cross-border electricity interconnection in the EU is essential for the security of supply and an enhanced integration of RES into energy markets. The EU countries aim to achieve an interconnectivity of their electricity production of 10% by 2020. This means, that every EU member state should have the capacity to transport 10% of produced electricity to neighbouring countries. The Regulation on the governance of the Energy Union introduced a new goal for interconnectors to cover 15% of installed electricity production in the Member States by 2030.
