1 1 Storm Center ® Online Outage Map Tim Prince, Emergency Operations Bob Williamson, GIS Support

2 2 Oncors Old Web-Accessible Outage Map

3 3 On March 30 Oncor Introduced Storm Center ® (Storm Center is a product of iFactor Consulting which displays Oncors OMS data --

4 4 Four Days Later…

5 5 Seventeen Tornados Struck Oncors Service Area

6 6 Doing extensive Property Damage

7 7 Knocking out Power to 40,000 Customers

8 8 Storm Centers Display during the Storms

9 9 Tornado in South Arlington – Hail at DFW Airport

10 10 Affected Devices Highlight the Outage Area

11 11 Media Reporting was Focused on Dallas County; Oncors Statistics Showed Tarrant was Hardest Hit

12 12 Zip Code Took the Worst of the Storm

13 13 Geographical Display of Outages by County

14 14 Geographical Display of Power Outages by Zip

15 15 Zip Visibly Stands Out as the Most Affected

16 16 Coming soon … Register your account via mobile device. Report outages and receive updates.

17 17 Distribution Oncors Operations 2 Distribution Operating Centers Generation Transmission 3095 Feeders 3.2-million Customers 2 Data Centers Transmission Grid Management 1182 Substations 738 Distribution Substations SCADA OMS/AMS OMS/IVR 2 Phone Centers + Back-ups AMS IVR

18 18 IT Systems Supporting Restoration Operations Weekly DMS Storm Center Website

19 19 Future OMS-Storm-Center Enhancements Customers report outages to Storm Center (iFactors Notifi) Storm Center submits outage ticket directly to OMS Storm Center updates customers on status (via SMS message) Outage Management System Distribution SCADA Meter Data Management Storm Center Website Geographic Information System Command Center DMS AMS Work Management System GIS

20 20 GIS-to-OMS Interface Weekly DMS Storm Center Website

21 21 GIS: Source of Record for OMSs Electrical Connectivity

22 22 OMS: Uses a Weekly Extract of the GIS Connectivity Model

23 23 New GIS will Address GIS-to-OMS Interface Issues GIS & OMS will use identical connectivity models. GIS-to-OMS updates will be real-time & two-way. GIS will disallow user errors that adversely affect OMS. Outage Management System Distribution SCADA Meter Data Management Storm Center Website Geographic Information System Command Center DMS AMS Work Management System GIS

24 24 But Data Quality Issues Cant Wait for the New GIS New OMS Requires New Focus on GIS Data Quality: Connectivity –Unconnected Features –Half Connected Protective Devices –Protective Devices with Duplicate Nodes –Self-Referencing Protective Devices –Voltage Changes –Closed Loop Errors Phasing –Transformer/Conductor Phase Mismatches –Inconsistent Phase Changes –Number of Phases Increase (when tracing out from the substation) New OMS Requires Process Improvements related to GIS Support Implementing tool to comprehensively measure fitness of GIS data Developing process to better track GIS/OMS data issues Updating GIS user training to focus on: –The new OMSs greater dependence on GIS data quality –Insuring GIS data is updated when field changes are made –Personal accountability for GIS data quality

25 25 GIS Data Quality Issues Plague Other Utilities GIS Interest Group Mitigating Data Quality Issues

26 26 EPRIs Goal: Quantify Benefits of Good GIS Data Reduced cost of deploying AMS network ($4.5-million) Reduced outage durations Reduced overall cost of operations –Reduced windshield time –Reduced O&M labor expenses Improved safety (due to more accurate connectivity) Improved load management (matching loads to transformers) Improved load forecasting and system planning Improved material management and forecasting Improved information exchange: –Internal (between departments and IT systems) –External (with governmental agencies and customers)

27 27 Information Sharing = Better Outage Management Oncor is striving for better two-way customer communication
