Fig. 34 HAD average content/level scenarios: (150, 160, 165, 170, 175) 45 (15)/(6,10)
Figure 35 shows a reduction in the hydropower generation head ranging from 24
to 40%, which will have a similar effect on the decrease in hydropower generated
from the HAD due to the presence of the GERD as a consequence of a decrease in
the average HAD level, which corresponds to reductions in average annual storage
ranging from 30 to 50 BCM.
