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

  2. 2 “The electric age ... established a global network that has much the character of our central nervous system.” - Marshall McLuhan

  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. 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 PG&E’s Service Territory

  5. PG&E’s Electric System

  6. 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)

  7. Q: How quick can PG&E fix it? • A: It Depends! • Logistics • Personnel, equipment, and replacementpart 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

  8. 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. What comes first?

  9. 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 Help PG&E help you

  10. Thank You Jon Frisch Business Continuity & Emergency Planning
