36 Analysis of the Negative Spot-Prices on Total projection error Su Actual production from wind and solar was higher than projected, the total load was lower than projected the day before. The result was an oversupply with electricity of up to 15 GW. Source: Johannes Mayer, Fraunhofer Institute for Solar Energy Systems; Data: EEX 36
