Fig. 2: Power plant unavailability (%) due to low flows at the power plant level under the three climate scenarios.

Boxplots show the distribution ofclimate uncertainty, which is in the order of ±3%. For the majority of power plants and compared to the Baseline scenario (a, d), unavailability doubles in the near future scenario (b, e) and almost triples in the far future scenario (c, f). Most severe impacts occur in the upstream tributaries and smaller rivers. Boxplot notch is the median, the bar is the inter-quartile range (IQR), whiskers extend to 5th and 95th percentiles, dots are outside this range.
