27. Review of Various TF/WG Activities  RAS: Need for More granularity in Transmission Need to add one more year to data collection to eliminate current Summer in LTRA  RAITF: Reliability Assessment Improvement  RAGTF: Reliability Assessment Guidebook  RMWG: Reliability Metrics

28. Proposed Capacity Definitions  These definitions represent an enhancement over the current set in use for reliability assessments.  Proposed definitions were presented to the NERC PC at the June 4-5, 2008 meeting in Toronto for comment, and were also circulated to the PC’s subgroups.  The proposal addresses PC specific advice: treatment of resources in organized markets, and deals with the deliverability within the recommended categories

29. Comparison to Current Definitions  Existing – Certain  Existing – Uncertain  Future – Planned  Future – Proposed  Existing – Certain  Existing – Other  Existing but Inoperable  Future – Planned  Future – Other  Conceptual Current Definitions Proposed Definitions

30. General Concepts for Reporting Capacity  All existing capacity resources (iron in the ground) must be reported in one of the “Existing” categories In cases where categorization is unclear or difficult to determine, report as “Other”  “Future” capacity resources have achieved one of the milestones outlined in the definition (some degree of confidence that the resource will become available) Milestones include permitting, site work, or contracting status  “Conceptual” category used to capture expected resources that are less certain or are still in the planning/development stages (i.e. resources that could not be classified as “Future”)

31.  The goal of this Guidebook is to: Improve consistency and transparency of assessments Increase granularity in assessments Outline the process to assess emerging industry issues Foundations/expectations/requirement for the NERC portion of the assessments Provide a framework for conducting comprehensive and independent assessments  This Guidebook will be a reference for regional entities and registered entities, and is organized to clarify reliability assessment expectations and objectives.  It is intended to document expectations and provide a comprehensive outline for reliability assessments. RAG: Reliability Assessment Guidebook

32.  First Draft Completed, materials provided by RIS DCWG LFWG NERC Staff  Report being reviewed by RAG Task Force  Draft being Readied for October-November RAG Status

33.  June 15Draft Outline Completed  June 30Industry review of Draft Outline Completed  September 30Review of Draft with RAG members  October 15Guidebook preparation completed  December 5-6Review final Reliability Assessment Guidebook completed by PC  December 30Reliability Assessment Guidebook completed and launched RAG Updated Schedule

34. DCWG 2008 Work Plans #1  Seasonal and Long-Term Reliability Assessment Guidebook  Background: Regional entities perform reliability assessments using a variety of tools, assumptions and methodology. There is a need to provide a guidebook, for the regional entities to use in preparation of the assessments and for peer reviewers to ensure consistency in the reliability assessments, outlining NERC’s expectations and forming a foundation for a sufficiently robust reliability assessment. The objectives of the reliability assessment guidebook are: Clarifying reliability assessment expectations Fortify peer review of assessments Address inconsistency in regional responses Ensure transparency Increase linkage between NERC staff and regional assessments Balancing areas that cross regional entity boundaries, especially regional transmission organizations (RTOs) and Independent System Operators (ISOs), may require attention as their assessment can be fragmented between two regions and may not accurately reflect reliability The DCWG will contribute to the data collection portions of the LTRA Guidebook.

35. DCWG 2008 Work Plans #2  Use of Scenario evaluations to incorporate emerging issues into LTRA  Background: he LTRA provides a reference case from which select scenarios can be compared. Identifying significant emerging issues should drive scenario development. A process has been proposed by the RAITF that includes RIS/TIS/RAS identification of emerging issues, survey of the PC membership to develop a risk matrix, vetting the results and development of reliability assessment for comparative purposes to the LTRA reference case. Once approved by the PC, materials to support this process and execution of the process are next steps. DCWG will work with the Regional Entities to incorporate the data requirements for the 2009 and 2011 scenarios

36. DCWG 2008 Work Plans #3  Metrics development for 1-5 and 6-10 years  Background: The certainty and granularity of long-term and seasonal reliability assessments are different between the 1-5 year and the 6-10 year timeframes of the 10-year LTRA. In addition, metrics are also needed for seasonal assessments to provide an indication of continuity between the operating and future planning horizons. Meaningful metrics (beyond just capacity margin) are required to more fully assess regional/subregional reliability and adequacy and achieve an appropriate level of granularity; this work will also include considerations about the data that needs to be collected to calculate these metrics. DCWG will enhance the seasonal and LTRA data collection templates to support the metric collection DCWG to develop data collection forms and instruction sheets to support the collection of data and metric requirements identified DCWG will ready seasonal and LTRA templates for 2009 data collection by October 2008

37. DCWG 2008 Work Plans #4  Review the NERC reliability assessment analysis and processes The DCWG will review the NERC data collection process and reliability assessments for seasonal and LTRA and propose enhancements to the reliability indexes measured by NERC. Report that outlines the current data collection process/analysis and, if applicable, make recommendations for improvements. Report due to RAS in December 2008

38. DCWG 2008 Work Plans #5  Recommend changes to the data collected and the definitions to the RAS and PC. The DCWG will seek feedback from regional entities on the new supply and demand definitions proposed by RAITF, DSMTF and LFWG, approved by the PC. The DCWG will develop a summary of what worked and what needs further enhancements Summarize the findings to RAS. Report to RAS on seasonal and LTRA assessments for 2008 by: April for Summer May (LTRA) October for Winter

39. DCWG 2008 Work Plans #6  Collaborative meetings Annual meeting with EIA increasing coordination and providing input to EIA data collection activities. Actively engage other NERC Planning Committee groups to support the work plan DCWG to actively participate in the reliability assessment improvement process by providing liaison as appropriate. Provide periodic status reports to RAS during 2008

40. DCWG 2008 Work Plans #7  EIA 411 data collection Collect data on behalf of the industry for the Energy Information Administrations (EIA) form 411 DCWG will submit data per EIA’s deadlines annually April of 2008

41. Update on Task 5 Data Collection Survey Recommendations Response 1.NERC should send the data request in October rather than January-February 2.NERC should revise the NERC Regions submittal deadline for the LTRA annual Data Collection efforts from March 31 st to April 30 th. 3.NERC should hold Workshops earlier to explain the forms, data expectations and schedules. 4.Address the status of the MOD standards and the implications for LSE, RC compliance.

42. Feedback from Regions on Winter and LTRA Forms  Feedback & Comments

43. Update on Task 4 Review the NERC Analysis and Processes Phil Fedora: Review the NERC reliability assessment analysis and processes The DCWG will review the NERC data collection process and reliability assessments for seasonal and LTRA and propose enhancements to the reliability indexes measured by NERC. Report that outlines the current data collection process/analysis and, if applicable, make recommendations for improvements. Report due to RAS in December 2008
