EU nations agreed Wednesday to allow the European Commission to vet their oil and gas deals with third countries like Russia to guard against anti-competitive practices and supply disruptions.
Overcoming resistance from member states wary of ceding sovereignty, the EU executive welcomed the deal with the bloc's 28 nations and the European Parliament as a boost in its drive for a single EU energy market and to curb reliance on Russian gas.
Concerns in Europe over the EU's reliance on Russia for over a third of its gas needs have grown since pricing spats between Moscow and Kyiv disrupted gas supplies and in the wake of Russia's seizure of the Crimea region from Ukraine in March 2014.
The European Commissioner for Climate Action and Energy, Miguel Arias Canete, said the new rules would "guarantee that no energy deal jeopardizes the security of supply in an EU country, or hampers the functioning of the EU's energy market."
The commission says it needs the new rules because about a third of 124 energy-related intergovernmental agreements in Europe fail to comply with EU law and contesting them has proved difficult.
It wants to avoid a repeat of the legal headaches it faced when it ruled that Russian gas giant Gazprom's planned South Stream pipeline under the Black Sea ran counter to EU competition law, challenging a web of bilateral deals Russia had cut with Eastern European states.
Under the new rules, proposed by the commission in February, EU nations will have to allow Brussels to review intergovernmental agreements on oil and gas deals before they sign them. Electricity deals will have to be reported to the commission only after they are completed.
