There are various national laws regulating grid expansion. The purpose of the Energy Act (EnWG) is to secure an environmentally sound energy supply for society as a whole, based increasingly on renewable sources.
The Renewable Energy Sources Act (EEG) goes further with its sustainable development strategy: renewable energy should account for at least 50 per cent of production by 2030, with priority given to feeding in and transporting electricity generated from renewables. These targets can only be met by stepping up expansion of the extra-high voltage grid, which in turn requires accelerated planning and approval procedures as provided for by the Power Grid Expansion Act 2009 (EnLAG) and the Grid Expansion Acceleration Act 2011 (NABEG).
The goal of the Environmental Impact Assessment Act (UVPG) is to ensure that uniform principles are applied in specific projects aimed at effective precautionary action in environmental protection. Here, environmental compatibility and strategic environmental assessments serve to identify and evaluate the potential impacts on the environment.
