In a study for the German Ministry of Economic Affairs and Energy, Ecofys and partners developed a retrofitting strategy for power generation plants in order to guarantee system security in case of under- and overfrequency. Specifically, subject of the investigation was to show which types of installation (wind, biomass, combined heat and power and hydroelectric power plants) are connected to the electricity grid according to which regulations and to assess the hazard potential posed by these types of installation. On this basis, the efforts of adapting the installations to current requirements were estimated in order to ensure the stability of the power grid also in the case of incidents. As a result, the consortioum developed certain recommendations for action for the Ministry. In this process, also legal proposals for new regulation were developed.
