The new measures also give national regulators the right to refuse certification of a transmission system operator controlled by companies from non-EU states if they do not comply with the ownership-unbundling rules or if their market entry could jeopardise a given country's or the EU's security of supply.
Noua măsură oferă de asemenea agenţiilor naţionale de reglementare dreptul de a refuza certificarea unui operator de sisteme de transmisie controlat de companii din state non-UE dacă acestea nu respectă regulile de separare a proprietăţilor sau dacă intrarea lor pe piaţă ar putea periclita securitatea de livrare a unei ţări sau a UE.
