If the European Union’s ambition is to attain secure, sustainable, competitive and affordable energy for every European, member states should agree on how, when, and to what extent they would be ready to ensure energy solidarity and transparency among them. In the case of natural gas, this could well require strengthening the European Commission’s supervisory powers, at least for some time, in order to accelerate completion of the internal energy market and improving coordination of interactions with third countries, such as LNG exporters.
