Figure 4 -3 shows the effects on the probability of Powell going below minimum
power pool under the Hybrid revisions. The effect of increasing the balancing
elevation is a 1% increase in 1 year (2023) compared to the Hybrid Original. The
effect of extending the range for releasing 7.48 is a 1% decrease in 1 year (2017)
compared to the Hybrid Original.
