Recent geopolitical and environmental events have created a new urgency for a just energy transition and a socially inclusive modernization of the energy sector. This article critically evaluates the extent to which Article 194(1) of the Treaty on the Functioning of the European Union (TFEU), as the competence provision of EU energy law, is congruent with the energy justice framework emerging from social sciences. It establishes the substantive scope and justiciability of Article 194(1) TFEU, including the legal principles and so-called ‘guiding principles’ of the provision relating to the internal market, environmental protection, and energy solidarity. The article analyzes the potential and shortcomings of Article 194(1) TFEU in contributing to more equitable decision-making processes in EU energy law. It concludes by evaluating the provision as a regulatory instrument that facilitates the (re)balancing of competing interests of the energy sector. This research further concludes that social considerations of energy justice cannot be sufficiently addressed through Article 194(1) TFEU.
