As part of the FfE-Energietage 2019, the Forschungsgesellschaft für Energiewirtschaft awarded the Helmut-Schaefer-Prize for the first time to particularly high-quality master's theses in the field of energy economy and energy technology. It recognizes innovative solutions, scientific depth and practical benefits. There was one prize each for a master's thesis, which was written at the FfE and / or TUM and one that was written at another university. Our master student Christina Lang was able to convince with her master thesis on "Development of an Auction Design for a Flexibility Market Platform" and was awarded the prize. Congratulations!
