1 Preparing for emergencies and climate impacts Gina Blus Sustainable Communities Feb. 28, 2013

2 Emergency-related efforts Protecting public and employee safety is the responsibility of every department and individual at PG&E, so dealing with emergencies is part of the job Prevention: training, electric reliability upgrades, gas PSEP, 811, public service messages (magnetic balloons, downed power lines), encroachments Preparedness: first responder workshops, Red Cross partnership (Causes.com pledge, Ready Neighborhoods campaign) Response: Emergency Operations Centers, mobile command vehicles, repair and restoration crews

3 Pipeline safety enhancement plan Pipelines –Replace 180+ miles of transmission pipeline –Strength test (hydrostatic pressure test) 780+ miles –Inspect 200+ miles with a "smart pig" or camera –Retrofit 200 miles to accommodate in-line inspections Valves –Automate 220 valves on pipelines in highly populated and earthquake-prone areas Interim Safety Enhancement Measures –Continue validating the Maximum Allowable Operating Pressure for all transmission pipelines until testing and/or replacment –Reduce gas pipeline pressure in certain areas –Significantly increase patrols and leak surveys

4 Climate-related efforts 35 years of mitigating climate impacts through energy efficiency, clean energy, education 5 years of tracking and anticipating the impacts of climate change –Temperature change –Storm frequency and intensity –Rainfall and runoff patterns, including snowpack –Firestorms –Sea level rise –Extreme weather events (freezing, flooding)

5 Scary scenarios lessmore less sea level rise seawater intrusion flooding high tides ground movement more corrosion

6 Goal: reduce operational risks Scientists focus on next 1-3 decades –Temperature change: impact on electricity demand –Storm frequency and intensity –Rainfall and runoff patterns: declining snowpack –Firestorms –Sea level rise: impact on infrastructure –Extreme weather events (freezing, flooding Cross functional team will focus on need for capital investment, coordination with regional efforts, etc.

7 Primary activities to date Develop standard procedures for measuring temperature change, rainfall and runoff, and sea level rise; monitor annually Provide data to researchers; track reports and academic studies from local, national and global sources Model potential impacts; plan alternatives Include climate impacts in regular planning and upgrades, e.g. San Francisco Bay restoration, BayDelta Vision Learn from experience; update standards Work collaboratively with institutes and agencies
