Feed-in tariffs for renewable electricity have proven to be an effective and cost-efficient instrument because they provide long-term investment security; however, they do not incentivize grid and market integration. Feed-in premiums are a relatively novel instrument designed with the objective of keeping investment risks low while allowing for improved grid and market integration. This article analyses the German feed-in premium. The evaluation of the operation during the first year gives first indications that the market premium can contribute to the system and market integration of renewable energies, while still maintaining investment security. First impacts can be seen in the following fields: diversity of market actors, forecast accuracy, improved remote control and participation in the reserve markets. In general, it can be concluded that the German market premium has been able to trigger significant developments. However, additional assessments of the instrument are necessary in order to see whether the observed changes are sustainable and lead to the expected developments.
