“Power grids and storage technologies for the energy transition”

There are no regions in Germany where power grid bottlenecks justify the government’s plan to slow down renewable development with the reform of the Renewable Energy Act (EEG), according to a study by the German Institute for Economic Research (DIW) commissioned by the environmental Herrmann-Scheer-Foundation. “The necessity of extensive grid extensions identified by transmission grid operators is above all due to the current market design, with a feed-in guarantee for fossil power even at times of high overcapacity,” according to the study. Neither do storage technologies constitute a bottleneck for the energy transition in the power sector, write the authors. “Technical issues for a power system based on 80 to 100 percent renewables are considered to be solved.”
