Judgment_paragraph 29 · AS Veejaam and OÜ Espo v AS Elering (C-470/20)

29As regards the scope of an act such as the 2014 Guidelines, it must be borne in mind that, in accordance with the case-law of the Court, the assessment of the compatibility of aid measures with the internal market, under Article 107(3) TFEU, falls within the exclusive competence of the Commission, subject to review by the Courts of the European Union. In that regard, the Commission enjoys wide discretion, the exercise of which involves complex economic and social assessments. In the exercise of that discretion, the Commission may adopt guidelines in order to establish the criteria on the basis of which it proposes to assess the compatibility, with the internal market, of aid measures envisaged by the Member States (judgment of 19 July 2016, Kotnik and Others, C‑526/14, EU:C:2016:570, paragraphs 37 to 39).
