In a new study, the EWI has examined the stagnating expansion of onshore wind energy in the context of the German coal phase-out. The EWI’s analysis yields the following key results: The lack of wind power is mainly compensated by the use of combined cycle gas power plants and electricity imports. As a consequence, the sectoral climate target of the energy sector will not be met in 2030. In the event of a reduced expansion of wind energy, there will be an additional increase in wholesale electricity prices. On the other hand, the EEG levy falls more sharply in the scenario with a sluggish expansion of wind energy. The study was commissioned by the Gesellschaft zur Förderung des Energiewirtschaftlichen Instituts an der Universität zu Köln e. V.
