  1. Outage Coordination Process and New Equipment

  2. Introduction This presentation is intended to increase knowledge of outage coordination and NOMCR submittal processes

  3. Objectives • At the completion of this course of instruction you will: • Identify the ERCOT Outage Coordination timelines • Identify the timeline requirement for a maintenance level outage • Identify the maximum size of a group outage • Identify the correct process order for new equipment in the ERCOT system

  4. Definitions • NOMCR – Network Operations Model Change Request • ResTran – RESourceOwned TRANsmission Equipment

  5. Outage Coordination Planned Transmission Timeline *Prior to Planned Start Date/Time

  6. Outage Coordination Planned Resource Timeline

  7. Outage Coordination Planned Resource Timeline • Timelines for Reliability Resource Planned Outages (RMR and Black Start) Note: ERCOT may, at its discretion, relax the 30 day Notice requirement. 7

  8. Outage Coordination Maintenance Timeline Definition: Initiated manually to remove equipment from service to perform work on componentsthan could be postponed briefly but is required to prevent potential forced outage and cannot be postponed until the next planned outage.

  9. ResTran • Forms are available on resquest • Email forms to ResTranOutages@ercot.com • Different forms for Forced Outages

  16. ResTran Outage Form • ALWAYS review the outages after they were submitted by ERCOT on your behalf to make sure that the outage does exactly what you want it to do when you want it to. • To update an outage email the most up-to-date form with the new updated information added.

  17. Outage Coordination Approvals • Approved Outages can be withdrawn any time before it is completed. • Planned transmission outages are always studied. • Approved -> Done by coordinators • Accepted -> Automatic

  18. Outage Coordination Availability • Short Term: M-F 6AM-6PM, Sa-Su 6AM – 2PM • Rotating Shifts* • Long Term: M-F 6AM-5PM • Use OC Blast Accounts • Email: OPSOutageCoordination@ERCOT.com • Phone: (512) 248 – 6841 • No Voicemail*

  19. New Equipment • Create plan for switching from old to new equipment • May require pseudo equipment • i.e. Breakers to switch between equipment… • Submit a NOMCR for all new and pseudo equipment

  20. New Equipment • Pseudo Equipment Pseudo Breaker New Breaker Breaker Old Breaker

  26. New Equipment Outages • After the NOMCR has been processed and the equipment has been added to the OS Database • Planned End Date is the Energization Date • NOMCR >> OS >> Model

  27. **BONUS** • Extending an outage • New Planned End Date • Unlimited extensions • FR->FE || (PL,M1,M2,M3)->UE • Adding Requestor Notes • 1000 Characters • Only once per group outage • The maximum Group Outage size is 30 pieces of equipment

  28. **BONUS MIS** *All reports are automatically updated every hour on the hour Proposed Transmission Outages Outage Submitted *When an outage is added to one report it is removed from the previous report Outage Rejected Outage Approved/Accepted Outage Canceled Approved and Accepted Transmission Outages Rejected Transmission Outages 2 Hrs. After Actual End Entered Outage Withdrawn Planned End > 1 Yr. Old Or Outage Canceled Withdrawal of Approved and Accepted Transmission Outages Removed from MIS Planned End > 1 Yr. Old
