1. 1 Electric and Gas Service: Recovery after Disaster Association of Bay Area Governments Infrastructure Interdependencies Workshop Jon Frisch Manager, Business Continuity & Emergency Planning PG&E January 31, 2012

2. Electric and Gas Service Restoration Following Disaster 2 “The electric age... established a global network that has much the character of our central nervous system.” - Marshall McLuhan 2

3. Electric and Gas Service Restoration Following Disaster 3 Topics for This Discussion Overview of Gas and Electric Systems What can go wrong in an earthquake? What are PG&E’s priorities after an earthquake? What can improve or interfere with PG&E’s ability to restore service?

4. Electric and Gas Service Restoration Following Disaster 4 PG&E’s Service Territory 141,215 circuit miles of electric distribution lines 18,616 circuit miles of interconnected transmission lines. 42,141 miles of natural gas distribution pipelines 6,438 miles of transportation pipelines. 5.1 million electric customer accounts. 4.3 million natural gas customer accounts 20,000 employees

8. Electric and Gas Service Restoration Following Disaster 8 Q: What can go wrong with the systems in an earthquake? A: It Depends! Fault, epicenter, magnitude Time of day, day of week, season of year Extent of liquifaction, land-slides, subsidence Structural damage including building collapses, fires Adjacent infrastructure damage(water, sewer, roadways)

9. Electric and Gas Service Restoration Following Disaster 9 Q: How quick can PG&E fix it? A: It Depends! Logistics –Personnel, equipment, and replacement part availability –Ability to get into damaged area –Ability to communicate Environment –Frequency and size of aftershocks –Ability to work safely System Specifics –Transmission comes before distribution (gas & electric) –Gas takes potentially much longer than electric –Below-ground takes longer than above-ground –Need to balance electric load may create interim reliability problems

10. Electric and Gas Service Restoration Following Disaster 10 What comes first? PG&E Priorities Protect health and welfare of the public and the responders Protect property of the public and the utility Restore service Keep constituencies informed Resume business as usual Who gets their service back first? It depends! Pre-defined critical need customers (e.g., hospitals, water pumping) have priority An operational decision Local concerns should be raised through liaison in EOC or SOC.

11. Electric and Gas Service Restoration Following Disaster 11 Help PG&E help you Contributory Facilitate access Facilitate communication Repair surrounding infrastructure Liaison: –Coordinate messaging –Keep PG&E informed on local government priorities, actions, and changes that impact us –Communicate through established channels (follow the process) Recognize this will be a regional response Remember some issues are the property-owners, not PG&E’s Interference Avoid giving us conflicting guidance Don’t take our stuff Don’t miscommunicate to the public about power or gas Share your toys if you can
