rare, it can be addressed by setting maximum procurement limits on each of the south of Path 26 AS sub-Region and the north of Path 15 AS sub-Region. Forecasted congestion on Path 15 in the south to north direction simultaneous with north to south Congestion on Path 26. While this scenario is expected to be rare, it can be addressed by setting minimum procurement limits on each of the south of Path 26 AS Sub-Region and the north of Path 15 AS sub-Region. For each of these conditions where congestion is assumed (Items 2 through 7 above), the AS Sub-Region may include the System Resources that are interconnected to that portion of the CAISO Controlled Grid. The determination of whether or not to include the System Resources in the AS Sub-Region depends on the nature of the system conditions, including the expected loading on the Transmission Interfaces that interconnect System Resources to the CAISO Controlled Grid Based on these criteria, there are eight AS Sub-Regions in addition to the Expanded System Region and the System Region, as follows: Exhibit 41: Summary of Initial AS Regions Description of AS Region AS Region Name (set of resources included in AS Region) AS Region Internal Intertie Resources Status CAISO Balancing (current Scheduling Points) Authority Area 1 Expanded System All internal Generators All Active 2 System All internal Generators None Active 3 South of Path 15 All Generators residing None Active South of Path 15 4 Expanded All Generators residing NW3, SR3, NV3, NV4, AZ2, Active AZ3, AZ5, LC1, LC2, LC3, South of Path 15 South of Path 15 MX, LA1, LA2, LA3, LA4, LA7 5 South of Path 26 All Generators residing None Active South of Path 26 6 All Generators residing NW3, SR3, NV3, NV4, AZ2, Active Expanded AZ3, AZ5, LC1, LC2, LC3, South of Path 26 South of Path 26 MX, LA1, LA2, LA3, LA4, LA7 7 North of Path 15 All Generators residing None Active North of Path 15
