  1. NERC Reliability Functional Model Conference on Electric System Reliability December 1, 2003

  3. Interchange Transmission Service Buy and Sell Own Implement Operate Wheel The Control Area: Vertically Integrated Transmission Reliability Load-Resource Balance Generation Supply Load

  4. Generator Transmission Owner Transmission Operator Distribution Provider Load-serving Entity Unbundled

  5. What do we do now? • The Control Area is no longer the only operating organization • NERC Operating Policiesdo not reflect the neworganizations ormerchant functions thatare forming • Need to define the basicfunctions and “roll up”into organizations • Traditional utilities • ISOs • RTOs Roll Up • Reliability • Balancing • Interchange • Transmission

  6. PSE IA RA TSP The Functional Model • List every reliability task we could think of Development Group into Functions • Assign to Responsible Entities • Invent new names as needed • Set up relationships

  7. Considerations • The Model accommodates the industry’s changes – does not cause or recommend change • Designed to accommodate traditional, vertically integrated control areas • …and RTOs • …and ISOs • Framework for NERC’s reliability standards • Does not depend on market structure or even whether a market exists

  8. Guiding Principles • Model defines functions as sets of tasks • Organizations register as responsible entities • Organizations must be certified to perform certain functions • Operating Reliability, Balancing, Transmission Operations, Interchange • May delegate tasks but not responsibilities • Some tasks will not result in standards

  9. Functional Model Version 2

  10. Putting it all Together Functional Model Reliability Standards Defines functions as tasks Defines responsibleentity relationships Defines satisfactory task performance Defines ability to perform tasks Organization Registration & Certification Regional Reliability Plans Designates which organizations are Reliability Authorities and Balancing Authorities Certifies organizations as responsible entities
