The Vienna Forum on European Energy Law took place on 13 March 2015 in Vienna. Organised for the third time, the Forum is a joint initiative of the Energy Law and Policy Area of the Florence School of Regulation (FSR, European University Institute) and the Energy Community Secretariat, and is designed to highlight issues topical both for the European Union (EU) and the Energy Community (EnC). This year, the Forum brought together about 150 experts from regulatory authorities, governments, EU institutions, law firms, consultancies and energy companies from the EU and the Energy Community Contracting Parties, and provided a platform for knowledge and practice sharing among professionals dealing with different aspects of energy market regulation on a daily basis.
