1. 1 RTWG Tariff update to the BOD, MOPC, SPC, and RSC January 4, 2005

2. 2 RTWG Tariff Update  Where are we in the process  What is the expected timeline for completion  Review of the proposed tariff changes

3. 3 Overview  RTWG is making changes to the tariff to implement the RSC approved Participant Funding plan  Clarifications or fundamental questions regarding the plan are referred back to the RSC/CAWG  RTWG is NOT discussing the merits of the plan

4. 4 A Review of the RSC Plan  100% of the costs of approved Base Plan upgrades are recovered through the tariff  The Plan defines the rules for how an upgrade is included in the Base Plan  RTO approved reliability upgrade  Upgrades required by a Network Customers to receive power from a new DNR if upgrades meet certain criteria

5. 5 RSC Plan (cont)  Conditions for Base Plan Treatment of upgrades for new DNRs  Minimal cost (<$100,000)  DNR must be a 5yr or longer firm entitlement  Customer can not exceed a 125% reserve margin  Upgrade costs capped at $180,000/MW  The Plan does allow for SPP to waive some or all of the above conditions

6. 6 RSC Plan (cont)  Waiver requirements  Customer must request the waiver and give supporting documentation  SPP staff will review the waiver request  SPP staff will then present the waiver request and its recommendation to the MOPC  MOPC will pass the waiver, the SPP staff recommendation and its recommendation to the BOD  SPP BOD will decide on the waiver request  The customer has the right to present their position at all levels

7. 7 Required Tariff Changes  The RSC Plan calls for major changes in rate design  Will have a two tiered rate:  Current Zonal Charge – For customers that take service under the tariff  Base Plan Charge –applied to all load in SPP for recovery of Base Plan upgrade costs with regional and zonal components  Facilities not eligible for Base Plan treatment directly assigned with revenue credits  A new schedule is required to implement the plan  The remaining changes are primarily in rewriting Attachments H, J, L & S

8. 8 Issues Still Before the RTWG  Outstanding questions posed to the RSC/CAWG  Can a customer recover any directly assigned costs as a credit pursuant to Attachment Z?  How should the Credits for delayed or deferred Base Plan Projects be calculated? (RR or Cost)  Should project costs of < $100,000 be directly assigned to the host zone or split between the Regional and zonal rates?  Finalize remaining tariff language

9. 9 Possible Reasons for Delaying a Filing  Delayed response from RSC/CAWG to outstanding questions  Responses from RSC/CAWG require major changes to proposed language  A problem in the proposed tariff language is discovered at the last minute  RSC/CAWG request changes to the proposed tariff language  Proposed Language is not approved by the MOPC and/or the BOD

10. 10 Time Table  RTWG meets this week to try and finalize the tariff language  Targeted to get language to MOPC and BOD for their review and approval at their respective January meetings  December FERC filing provides for January policy review and February implementation of any directives  SPP committed to file by March 1
