8. ATSS Completion Agreement (ACA) and Process • ACA tendered only for studies that are first in queue and after AFS-4 • ACA covers the request through the completion of the study • Customer commits either to accept service offered within the ACA parameters or to pay a make-whole payment • Baseline values are the values from the pre-ACA study iteration and customers can enter greater “acceptable” values

9. ACA Contents • Additional components of ACA: • Agreement with Table 1 for OASIS requests • Appendix 1 – Study parameters • Appendix 2 – Mutually exclusive requests

10. ACA – Table 1 • ACA Table 1 will list all OASIS requests covered by agreement: • Any related GI study number should be included in the ‘GI Study Number’ column

11. ACA – Appendix 1 Customer selects study option at top of Appendix 1. Remain: Items 1-5 must be completed. Sign and date at bottom.

12. ACA – Appendix 1 Customer selects Expedited Service, Accepts ATC or Withdraws, then skip items 1-5 and sign and date at bottom.

13. ACA – Appendix 1 – cont. (1) Directly Assigned Upgrade Costs (DAUC) • Customer can specify a maximum amount, but no less than its DAUC from the iteration prior to signing the ACA • If no maximum amount is provided in (1)(b), the value from the most recently posted study will be utilized

14. ACA – Appendix 1 – cont. (2) 3rd Party Upgrade Costs • Customer can specify a maximum amount, but no less than its costs from the iteration prior to signing the ACA • Customer can elect to either remain in the current study or move to the next highest priority study in queue if the 3rd party cost is non-zero or listed as indeterminate • If no maximum amount is provided in (2)(b), the value from the most recently posted study will be utilized • If no selection is made for (2)(c), the request will remain in study

15. ACA – Appendix 1 – cont. (3) Deferred Start Date without redispatch • Customer can specify the latest acceptable start date • If date in (3)(b) is left blank, the Start Date from Most Recently Posted Study will be the default date

16. ACA – Appendix 1 – cont. (4) Interim Redispatch, if it can provide an earlier Start Date • Customer can specify if Interim Redispatch is acceptable • If no selection is made, then ‘No’ will be the default

17. ACA – Appendix 1 – cont. (5) Letter of Credit (if required) • Customer can specify a maximum amount • If no maximum amount is provided in (5)(b), the value from the most recently posted study will be utilized

27. Make-whole payment (mwp)

28. Make-Whole Payment (MWP) • Customers that sign an ACA without executing a Transmission Service Agreement (TSA) are obligated to pay for any shared upgrade costs in the form of a MWP • Customers that pay a MWP will execute a Sponsored Upgrade agreement under Attachment J • Sponsored Upgrades are eligible to receive revenue credits under Attachment Z2

29. Make-Whole Payment (MWP) Process Re-Run Cost Allocation & Prepare Sponsored Upgrade Agreements Notify Customer of MWP and Tender Sponsored Upgrade Agreements Settlement of Make Whole Payment Incorporate into Creditable Upgrades Database

30. Maximum Potential MWP Example • Excerpt from Table 3 of study report showing Service Upgrades allocated to a request Maximum Potential MWP: $1,098,494 • The highlighted cells depict the potential MWP for each upgrade, based on the revenue requirements. • The non-highlighted upgrades are non-shared upgrades and are not included in the MWP calculation.

31. Non-Shared Upgrades • Non-shared upgrades will not be included in the Make-Whole Payment for requests that are not confirmed • Exception: • Non-shared upgrades that are allocated to a request with a third-party impact that exercised the option to postpone action will be included in subsequent studies • If service is granted to subsequent requests that rely on the non-shared upgrade, the original request will be assigned a MWP if the request is not confirmed

32. Open season extension

33. Open Season Extension • Open season will remain open until either the immediately prior study becomes the highest priority study or SPP Staff determines the Open Season needs to close • SPP will give at least 10 days’ notice before the open season closes • The Open Season will be open for no less than 4 months • 2014-AG1 will be the first open season to be extended

34. One-time cost-causer exemption

35. One-Time Cost-Causer Exemption • Customers will have an opportunity to withdraw any pending aggregate study request without incurring an obligation to pay for subsequent restudies • Customers have 45 days after FERC acceptance of the tariff language to exercise the option • This is a one-time exemption

36. WRAP-UP

37. Implementation Timeline • Filed Tariff Aug. 15, 2013 • FERC order expected by Oct. 14, 2013 • Letters of Intent due for 2011-AG3-AFS-10 on Oct. 12 • If FERC issues an order by COB October 14, 2013 and accepts the October 12, 2013 effective date, then: • 2011-AG3 will be subject to BCP if it did not complete with AFS-10 (ACA will be tendered) • If October 12th is not the effective date, 2011-AG3 will continue under the Current Process if it did not complete with AFS-10
