This article is brought to you in association with the European Commission. The European Commission has opened a formal antitrust investigation to assess possible abusive behaviour by Public Power Corporation (‘PPC’) in the wholesale Greek electricity sector. Executive Vice-President Margrethe Vestager, in charge of competition policy said: “We all rely on well-functioning electricity markets. Today we are launching an investigation of PPC’s behaviour in wholesale electricity markets in Greece that might have distorted competition and slowed down investment into the generation of greener energy. Greece has recently embarked on an ambitious plan to exit from lignite. Ensuring effective competition is the best way to deliver competitively priced electricity, both for citizens and businesses, as well as to stimulate investment in less polluting energy sources.”
