Leigh Hancher Energy & State aid : An overview of EU and national case law


State aid to the energy sector has grown steadily in volume and as consecutive issues of the Commission’s ‘State Aid Scoreboard’ have confirmed, it is after emergency or crisis aid granted on the basis of Article 107(3)(b), the second most important type of aid in terms of spending across the 27 Member States. The current set of ‘soft law’ guidelines for the assessment of the compatibility of state aids for climate, energy and environmental objectives – the CEEAG – is an extensive document covering many forms of support to combat climate chain and promote the energy transition. Nevertheless, the adoption of the new CEEAG has coincided with the outbreak of the war in the Ukraine and the onset of a major energy crisis in Europe and elsewhere. A large volume of aid is now being screened under the Temporary Crisis Framework (TCF), discussed below.
