  6. Key Findings of Investigation

  7. Causes of the Blackout • Inadequate Situational Awareness • Failure to manage tree growth in ROWs • Failure of Reliability Coordinators diagnostic support

  8. Violations of NERC Reliability Standards • Failure to return system to safe operating state within 30 minutes • Failure to notify others of impending emergency • State estimator was not used • Inadequate training • Reliability coordinator did not notify others • Reliability coordinator did not have adequate monitoring capability

  9. Key Findings • Several violations • Compliance monitoring process is inadequate • Differing interpretations • Repeats past mistakes • Data deficiencies in models • Planning inadequate • Technologies inconsistent • Communications not effective

  10. NERC Guiding Principles • Specific information on all violations • Improve compliance • Greater transparency to violations • Work closely with FERC, states, provinces • Ensure public interest is met

  11. NERC Blackout Recommendations • Corrective actions • Strategic initiatives • Technical initiatives

  12. Corrective Actions • Specific actions to correct the direct causes of the blackout • Certify actions completed by June 30 • Experts to be available to assist

  13. Strategic Initiatives • Readiness audits • Performance audits • Vegetation-related outage reporting • Recommendations implementation tracking

  14. Readiness Audits • Audit all control areas and reliability coordinators • Conduct every 3-years • Reports to the board

  15. Performance Reviews • Modify NERC Compliance Enforcement Program • Regions to submit results to NERC • Provide list of non-compliant entities • Regular confidential reports to the Board • Specific violations • Results of audits

  16. Vegetation Outage Reports • Transmission owners to report tree contacts to Regions (230+ kV) • Regions report to NERC • Use WECC as model • Regions to conduct annual vegetation management surveys

  17. Recommendations Tracking • NERC and Regions will track: • Implementation of recommendations • Compliance audits • Lessons learned from system disturbances • Use successful regional processes as model

  18. Technical Initiatives • Operator & reliability coordinator emergency response training • Reactive power & voltage control • Cascade mitigation • RC & CA responsibilities • Real-time operating tools • Restoration review • Time-synchronized measurements • Reevaluate system design, planning & operating criteria • System modeling & data exchange standards

  19. So Where Are We? • NERC Steering Group – technical investigation is ongoing • Recommendations approved by NERC standing committees, stakeholders, and Board of Trustees • Implementing recommendations • Finalize technical report this spring

  20. Issues to be Resolved • Role of FERC, NRCan • Non-jurisdictional entities • Funding: resources and $$$ • Migrating old standards to new • Recommendations in final report • Voluntary vs. mandatory reliability standards or: Will reliability legislation ever pass??

  21. NERC Actions to Address the August 14, 2003, Blackout National Energy Restructuring Conference April 1, 2004 Washington, DC
