Germany is facing the challenge of converting its electricity system to renewable energies. Far-reaching changes to the electricity market are necessary to make this transition a success. Researchers from the Kopernikus project Ariadne have identified 18 possible measures that can help to create a flexible and efficient electricity system. Researchers from the Fraunhofer Cluster of Excellence CINES are part of the consortium.

The key challenges here are the integration of fluctuating energy generation, security of supply, the costs of the energy transition and the fair distribution of these costs. The researchers have developed an evaluation system to compare the various measures in terms of their climate impact and other criteria.

One important aspect is the design of electricity prices. Dynamic electricity tariffs could help to adapt the demand for electricity to the availability of renewable energies.

The implementation of the energy transition requires close cooperation between politics, business and society. It is important to create a legal framework that promotes investment in renewable energies and at the same time protects consumers.
