This has been confirmed by Germany in its comments regarding State aid SA.46526 (2017/N) in which Germany first indicated that self-supply solutions in the energy-intensive industry were driven by synergies with heat requirements, synergies with waste gases and production residues and not by the possibility to escape payment of the charge on electricity that consumers pay in Germany to finance the support of renewable electricity (the so-called EEG-surcharge).
Au contraire, il est souligné dans l'étude de 2012, à la page (i) de la synthèse des résultats que le niveau de la production minimale nécessaire dépend beaucoup de la situation du moment, notamment de la production à partir d'énergies renouvelables, mais aussi de la charge de consommation (voir le considérant 93).
