Figure 3: The resulting system costs of deflex have been compared with the day-ahead prices from the Entso-e downloaded from Open Power System Data. The plot shows three different periods of the year.

Figure 4: It is also possible to get a time series of the average emissions. Furthermore, it shows the emissions of the most expensive power plant which would be replaced by an additional feed-in.

Figure 5: The following plot shows fraction of the time on which the utilisation of the power lines between the regions is more than 90% of its maximum capacity:
