An annual seminar for alumni of the Oldenburg wind studies programme was held at the Centre for Wind Energy Research (ForWind) at the beginning of September. This year's topic was "Energy transition and electricity grids: How can the bottleneck be overcome?" In April of this year, the German Renewable Energy Federation and the Fraunhofer Institute for Energy Economics and Energy System Technology published a study on the joint use of grid connection points by renewable energy producers, electricity storage facilities and sector coupling systems. The study shows the challenges and potential that lie in this more efficient utilisation of the grid infrastructure. Following specialist presentations, the results of this study were discussed with the alumni in a panel discussion with Ricarda Schmidt-Scheele and other experts.
