To examine the individual regions in better detail, Figure 5-2 through Figure 5-6 show the
generation by unit type in each region for all scenarios. Figure 5-2 shows that the main change in
Entergy is an increase in CC output relative to scenario 1 for all but the proxy (balancing cost)
scenario. As each subsequent scenario represents a greater level of coordination in terms of
balancing, scheduling and reduced contingency requirements, the increasing utilization of
Entergy CCs as cooperation increases indicates that in the models utilized, they are less
expensive than other CCs (and GTs) and can displace these types of generation when allowed to
do so. From the results, it seems that Entergy would increase its participation in the region as
more cooperation is allowed.
