Press Release: Judgment in Case C-226/16. Eni and Others v Premier Ministre and Ministre de l’Environnement, de l’Énergie et de la Mer

Member States cannot require natural gas suppliers to hold exclusively on national territory sufficient natural gas stocks to fulfil the obligations laid down by the EU
regulation on security of gas supply.

They can, however, widen the group of customers for which gas supply is safeguarded in the crisis situations referred to in that regulation, provided that they comply with the conditions laid down in the regulation.
