Energy supply security has become a key issue in law and politics in recent years. The main reasons for this are the desired decarbonisation of the energy system and the phase-out of nuclear energy. But what does energy supply security mean? What requirements must be met for the energy supply to be considered secure? How is responsibility for this divided between the state and the energy industry? Articles 6–8 of the Swiss Energy Act (EnG) contain general requirements and guidelines on energy supply security, based on the energy policy objectives of the Federal Constitution of the Swiss Confederation. However, the significance and normative content of these provisions require clarification. This study aims to highlight the significance of Articles 6–8 EnG for legislators, authorities and the energy industry. It also addresses the fundamental question of how far the federal competences extend in terms of energy supply security.
