1 Outage Coordination Process and New Equipment 1

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

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 3

4 Definitions NOMCR – Network Operations Model Change Request ResTran – RESource Owned TRANsmission Equipment 4

5 Outage Coordination Planned Transmission Timeline Request for Approval* ERCOT must Approve or Reject* More than 90 days75 days 46–90 days30 days 9–45 days4 days 4–8 daysNo later than 1800 hours 3 days 3 daysNo later than 1800 hours 2 days *Prior to Planned Start Date/Time 5

6 Outage Coordination Planned Resource Timeline QSE Request for Approval ERCOT Approval or Rejection Three days1800 hours, two days prior to start of proposed Outage Four to eight days1800 hours, three days prior to start of proposed Outage Nine to 45 daysFive Business days after submission. Outages are automatically accepted if not rejected at the end of the fifth Business Day following receipt of request. Greater than 45 daysERCOT must accept, but may discuss reliability and scheduling to minimize cost. 6

7 Timelines for Reliability Resource Planned Outages (RMR and Black Start) Note: ERCOT may, at its discretion, relax the 30 day Notice requirement. Request for Approval ERCOT Approval or Rejection Not less than 30 days 15 days before start of proposed Outage More than 45 days30 days before the start of proposed Outage 7 Outage Coordination Planned Resource Timeline 7

8 Outage Coordination Maintenance Timeline Definition: Initiated manually to remove equipment from service to perform work on components than could be postponed briefly but is required to prevent potential forced outage and cannot be postponed until the next planned outage. Level 1:Applies to equipment which must be removed from service within 24 hours. (M1) Level 2:Identifies equipment which must be removed from service within 7 days. (M2) Level 3:Applies to equipment which must be removed from service within 30 days. (M3) 8

9 ResTran Forms are available on resquest forms to Different forms for Forced Outages 9

15 ResTran - Outage Form 15

16 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 the most up-to- date form with the new updated information added. ResTran Outage Form 16

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 17

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 – –Phone: (512) 248 – 6841 No Voic * 18

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 19

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 26

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 27

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