  3. Duke and Progress Attachment K Compliance Filing Kendal Bowman Progress Energy 3

  4. FERC Duke/Progress Attachment K Order – June 18, 2009 Duke/Progress Request for Clarification or in Alternate, Rehearing – July 20, 2009 Duke/Progress Attachment K Filing – August 17, 2009 4

  5. Duke/Progress Request for Clarification or in Alternate, Rehearing Duke/Progress had included wording in the SIRPP area of the tariff stating that resource specific confidential information would not be made available due to the competitively sensitive nature of the data. FERC ordered that this information must be released, under applicable confidentiality provisions, if the information is needed to participate in the transmission planning process and/or to replicate transmission planning studies. Duke/Progress Request for Clarification or in Alternate Rehearing seeks to clarify that the confidentiality agreements may restrict the availability of competitive confidential information, such that it is only available to non-merchant function personnel. 5

  6. Duke/Progress Attachment K Filing Added tariff language stating that the TAG “Eligible Customers and Ancillary Service Providers” Sector can include demand response providers. Added language that describes the process that the NCTPC will use to evaluate competing solutions submitted in the transmission planning process. Requires that the TAG participants submit information (cost, performance, lead time to install, etc.) associated with an alternative solution so that it can be compared to the transmission solution. 6

  7. Duke/Progress Attachment K Filing (cont.) Changes required related to acquiring data: Acquiring CEII data: Removed requirement to obtain Form 715 approval from FERC before the release of CEII data. NCTPC and SIRPP will now administer the approval process for obtaining CEII data. Removed provisions within the SIRPP area that had afforded special protections of release of non-public utility transmission provider data. Revised tariff language related to the release of competitively sensitive data, under appropriate confidentiality agreements (as explained in the Request for Clarification, or in Alternate Rehearing slide). 7

  9. NCTPC 2009 Study Scope Update and Status Bob Beadle North Carolina EMC 9

  10. Assess Duke and Progress transmission systems' reliability and develop a single Collaborative Transmission Plan Also assess Enhanced Access Study requests provided by Participants or TAG members Purpose of Study 10

  11. Study Year – near term reliability analysis: 2014 Summer, 2014/2015 Winter High load summer import sensitivity to CPLW Study Year – longer term reliability analysis: 2019 Summer LSEs provided: Input for load forecasts and resource supply assumptions Dispatch order for their resources Interchange coordinated between Participants and neighboring systems Study Assumptions Selected 11

  12. Study Criteria Established NERC Reliability Standards Current standards for base study screening SERC Requirements Individual company criteria 12

  13. Study Methodologies Selected Similarities to previous studies: Thermal Power Flow Analysis Voltage, stability, short circuit, phase angle analysis - as needed Sensitivity to examine the use of high temperature conductor on the DEC Caesar (Shiloh-Pisgah) 230kV line 13

  14. Latest available MMWG cases were selected and updated for study years (change made from previous studies to incorporate latest PJM transmission upgrades) Combined detailed model for Duke and Progress was prepared Planned transmission additions from updated 2008 Plan were included in models Base Case Models Developed 14

  15. 1. Assumptions Selected 2. Study Criteria Established 3. Study Methodologies Selected 4. Models and Cases Developed 5. Technical Analysis Performed 6. Problems Identified and Solutions Developed 7. Collaborative Plan Projects Selected 8. Study Report Prepared Steps and Status of the Study Process Completed 15

  16. Hypothetical imports To Duke To Progress To Duke and Progress Hypothetical export: CPLE to PJM Hypothetical base load generation Resource Supply Options Selected 16

  17. Hypothetical Import/Export Scenarios 17

  18. Bob BeadleNorth Carolina EMC NCTPC 2009 Study Preliminary Results 18

  19. 2014 Summer No issues identified in Eastern or Western Areas Projects already in place to address network loadings 2014-15 Winter Issues identified in Western Area Pisgah 115/110kV Transformers Asheville-DPC Pisgah 230kV Lines, Up-rate 2019 Summer No new issues identified in Eastern or Western Areas Preliminary Base Case Results – Progress Energy 19

  20. Contingencies & Year Upgrade Needed: Transformer replacement (loss of parallel bank) Pisgah 115/100kV transformer, 2018 Sadler 230/100kV transformer, 2019 Upgrades needed for loss of a parallel line: Davidson River 100kV line, 2014 Fisher 230kV line, 2016 Norman 230kV line, 2018 London Creek 230kV line, 2015 Preliminary Resource Supply Results - Duke 20

  21. Davidson River 100kV, Fisher 230kV, and London Creek 230kV contingencies are all adversely affected by summer CPLE to CPLW transfers, causes acceleration of projects from outside the planning horizon to in the study A third 230/100kV transformer is scheduled to be added at Sadler in 2016 Preliminary Resource Supply Results - Duke 21

  22. Caesar 230kV Line Project: Using high temperature conductor to rebuild the Caesar 230 kV (Shiloh-Pisgah) Lines only significantly affects the Davidson River 100 kV Lines Results show that reconductoring of the Davidson River Lines is required prior to 2014, which may not be feasible  Duke is exploring use of operating procedures to alleviate the loading on the Davidson River Lines Preliminary Resource Supply Results - Duke Preliminary Resource Supply Results - Duke 22

  23. TAG Input Request • TAG is requested to provide input to the OSC and PWG on the technical analysis performed, the problems identified as well as proposing alternative solutions to the problems identified • Provide input by September 18, 2009 to ITP (r.wodyka@accenture.com)

  24. Collaborative Plan Projects Selected Compare all alternatives and select preferred solutions Study Report Prepared Prepare draft report and distribute to TAG for review and comment 24

  31. Eastern Area Growth Slower than Projected Progress Energy 31 31

  32. Western Area Growth Faster than Projected Progress Energy 32 32

  33. Load Forecast Reduction Progress Energy 33 33

  34. Load Forecast Reduction Progress Energy • Eastern Area load reduction of 671 MW • Approximately 50% is Wholesale • 100 MW’s is DSM and Energy Efficiency • Remainder is loss of Industrial customers and a decline in Commercial Loads • Western Area increase of 87 MW • Peak loads have exceeded previous year projections • Industrial & Residential sectors have remained stable in WNC 34 34

  35. Load Forecast Reduction Duke Energy • Decrease in load of 400-500 MW or approximately 2 years of load growth • Going forward Duke would normally expect to see an annual increase of 225-250 MW/year  • With the economic downturn and the decrease in new residential connections the rate of load growth is expected to be lower than in the past. 35 35
