Recommended Appendix B Redirect Standards Examples (to replace existing Appendix B) Notes for Examples: In all cases a Parent Reservation to be Redirected must be Firm Point-to-Point. Unless noted otherwise, example Redirect requests may be on either a firm or non-firm basis. Capacity that is shaded (dotted) shows Parent Capacity Available to Redirect. Capacity in Gray is not available to Redirect. Requests that are cross-hatched are outside the bounds of the Parent Reservation.

Confirmed Firm Parent ARef# 2000 RECOMMENDATION TO NAESB WEQ EXECUTIVE COMMITTEE Requesters: Electronic Scheduling Subcommittee and Information Technology Subcommittee Request No.: R05002 Request Title: Revision of Redirect Standards 9 and 10 100 MW - Outage 60 MW - Confirmed Firm Parent ARef# 2000 20 MW - Day 1 Day 2 Day 3 Day 4 Example 2: Parent Capacity Available to Redirect Not Affected by Outage Example 2 – The Capacity Available to Redirect is unaffected by the outage. The Capacity Available to Redirect against Parent ARef# 2000 would be 100 MW’s for all four days. See Standards 9.2 and 10.2. R04035 and R05002 Page 3

RECOMMENDATION TO NAESB WEQ EXECUTIVE COMMITTEE Requesters: Electronic Scheduling Subcommittee and Information Technology Subcommittee Request No.: R05002 Request Title: Revision of Redirect Standards 9 and 10 Day 1 Day 2 Day 3 Day 4 60 MW - 20 MW - 100 MW - Confirmed Firm Parent ARef# 3000 Invalid Redirect ARef# 3001 Example 3: Redirect Request with Invalid Time Period Example 3 – The TP must deny Request 3001 because the time period is invalid (i.e. extends past the time period of the Parent Reservation). The Capacity Available to Redirect on the Parent Reservation remains at 100 MW for the duration of the reservation. See Standards 9.3, 9.4.1, 10.3 and 10.4.1 R04035 and R05002 Page 4

RECOMMENDATION TO NAESB WEQ EXECUTIVE COMMITTEE Requesters: Electronic Scheduling Subcommittee and Information Technology Subcommittee Request No.: R05002 Request Title: Revision of Redirect Standards 9 and 10 Non-Firm Redirect Request ARef# 4001 100 MW - 60 MW - Confirmed Firm Parent ARef# 4000 20 MW - Day 1 Day 2 Day 3 Day 4 Example 4: Non-Firm Redirect with Capacity Requested exceeding Capacity Available to Redirect on Parent Reservation. Example 4 – With a Non-Firm Redirect Request where the capacity requested exceeds the Capacity Available to Redirect of the Parent, if ATC is available, the TP may Counteroffer ARef# 4001 at 100 MW (See Example 4a) or deny ARef# 4001 (See Example 4b). In 4a, assuming the customer confirmed the Counteroffer, the Capacity Available to Redirect on Parent Reservation ARef# 4000 would be 100 MW for the first two days and zero for days 3 and 4. See Standards 10.4 and 10.5. 100 MW - Non-Firm Redirect ARef# 4001 Counteroffered and Confirmed at 100 MW Confirmed Firm Parent ARef# 4000 60 MW - 20 MW - Day 1 Day 2 Day 3 Day 4 Example 4a: Non-Firm Redirect with Optional Counteroffer.

RECOMMENDATION TO NAESB WEQ EXECUTIVE COMMITTEE Requesters: Electronic Scheduling Subcommittee and Information Technology Subcommittee Request No.: R05002 Request Title: Revision of Redirect Standards 9 and 10 100 MW - Denied Non-Firm Redirect ARef# 4001 60 MW - Confirmed Firm Parent ARef# 4000 20 MW - Day 1 Day 2 Day 3 Day 4 Example 4b: Non-Firm Redirect with Optional Deny. Example 4b – In this scenario, the TP denied the Non-Firm Redirect ARef# 4001. The Capacity Available to Redirect on Parent Reservation ARef# 4000 remains 100 MW for all four days. The TP could also Counteroffer Request 4001 at 100 MW (See Example 4a). See Standard 10.4.3. R04035 and R05002 Page 6

RECOMMENDATION TO NAESB WEQ EXECUTIVE COMMITTEE Requesters: Electronic Scheduling Subcommittee and Information Technology Subcommittee Request No.: R05002 Request Title: Revision of Redirect Standards 9 and 10 100 MW - Firm Redirect Request ARef# 5001 60 MW - Confirmed Firm Parent ARef# 5000 20 MW - Day 1 Day 2 Day 3 Day 4 Example 5: Firm Redirect with Capacity Requested exceeding Capacity Available to Redirect on Parent Reservation. Example 5 - With a Firm Redirect Request where the capacity requested exceeds the Capacity Available to Redirect of the Parent, assuming ATC is available, the TP must Counteroffer ARef# 5001 at 100 MW. Assuming also that the customer confirmed the Counteroffer, the Capacity Available to Redirect on Parent Reservation ARef# 5000 would be 100 MW for the first two days and zero for days 3 and 4. See Standard 9.4.3. 100 MW - Firm Redirect ARef# 5001 Counteroffered and Confirmed at 100 MW 60 MW - Confirmed Firm Parent ARef# 5000 20 MW - Day 1 Day 2 Day 3 Day 4 Example 5: Firm Redirect with Counteroffer R04035 and R05002 Page 7

RECOMMENDATION TO NAESB WEQ EXECUTIVE COMMITTEE Requesters: Electronic Scheduling Subcommittee and Information Technology Subcommittee Request No.: R05002 Request Title: Revision of Redirect Standards 9 and 10 Day 1 Day 2 Day 3 Day 4 60 MW - 20 MW - 100 MW - Confirmed Firm Parent Reservation ARef# 6000 Accepted Non-Firm Redirect ARef# 6002 Accepted Non-Firm Redirect ARef# 6001 Example 6 – Multiple requests for Firm or Non-Firm Redirects may be pending against the same Capacity Available to Redirect. Once Request 6001 is Confirmed, Non-Firm ARef#6002 may be Refused by the TP or Withdrawn by the Customer. The Capacity Available to Redirect on ARef# 6000 is 40 MW for days 1 and 2. (The TP could also Counteroffer non-firm ARef# 6002. This scenario is not shown). See Standards 10.4.2, 10.5 and 10.5.2. 100 MW - Withdrawn Non-Firm Redirect ARef# 6002 Confirmed Firm Parent Reservation 5000 60 MW - Confirmed Firm Parent Reservation ARef# 6000 Confirmed Non-Firm Redirect ARef# 6001 20 MW - Day 1 Day 2 Day 3 Day 4 Example 6: Multiple Requests against same Capacity R04035 and R05002 Page 8

RECOMMENDATION TO NAESB WEQ EXECUTIVE COMMITTEE Requesters: Electronic Scheduling Subcommittee and Information Technology Subcommittee Request No.: R05002 Request Title: Revision of Redirect Standards 9 and 10 100 MW - Accepted Firm Parent ARef# 7000 60 MW - Refused Redirect ARef# 7001 20 MW - Day 1 Day 2 Day 3 Day 4 Example 7: Redirect Parent Reservation must be Confirmed Example 7 – The Customer may only Redirect against capacity of a reservation that is in a Confirmed State. ARef# 7001 would be Refused and the Capacity Available to Redirect against Parent ARef# 7000 would be zero MW’s for all four days because the reservation is not Confirmed.
