OUR COMMITMENT TO CALIFORNIA Keeping our communities safe from wildfires To Our Southern California Edisen Community During the week of Oct. 27, ferocious Santa Ana winds prompted the National Weather Service to issue an unprecedented extreme red flag warning for much of Southern Califorma Those strong Santa Anas lived up to their promise, fanning the fames of many fires over several days to the firefighters and first responders who worked around the clock in the most dangerous of condisions to save our communities-thank you. To our neighbors who helped each other evacuate safely and who opened your doors to strangers-thank you Since july, and increasingly in the last several weeks, we have exercised Pubilic Safety Power Shuofs (P5 to reduce the risk that our electric equipment starts a fire.while we recegnize these shutoffs are a significane hardship for you, our customers, they serve a vital purpose. In fact, patrols conducted after PSPS events found several instances of equipment damage and tree branches contacting power lines which could hve ignited a fre. I For years, we have been investing in a smarter, stronger grid. Since 2008, we have invested about S27 billion to maineain, upgrade and modernize our electric system with state of-the art technology that improves relability and resilency whlie also coneributing to reducingg wildfire risk and meeting our customers future needs. This includes automated switches and other equipment which can isolace sections of our circuits in igh fire risk areas to reduce the number of customers affected. We also have remote controled automatic devices that stop affected circuits from automatically re energizing so SCE crews can physically inspect the Snes before they are re energized. Climate change and the increasing number of people living in high fire risk areas, however, mean we need to accelerace that work in some areas SCE remains focused on implementing our Wildfire Mtigation Plan and our Grid Safety and Resilency Program to further harden our infrastructure, bolster our situational awareness capabilities and enhance our operational practices Over the past 13 monehs, we have deployed 470 of our planned 850 weather stations to monitor temperature, wind speeds and humidity levels, and more than 130 of our planned 160 highdeintion cameras to more quickly detect fire ignitions We have installed the first 300 miles of insulated wires, with plans to replace nearly 1,000 miles by the end of 2020 and to install about 4.900 additional miles between 2021 and 2023 and We have installed fas-acting fuses at approaimasely 10.000 new locaions, with plans to upgrade thousands more These efforts are designed to reduce the chance of cataserophic wildfres. wieh our work on weather stations, weather modeling more granular risk models and observations from the feld, we can be more argeed in applying PSPS. That means we espect to reduce the need for these shutoffs we recogze that SCE hars an imoortant role to elavinkeeping our communites 1afeyet our collective safety requires the combined efforts of our partners We are grateful for our state leaders commitment to increase the number of firefigheers, areraft, engines and tools available to combut fires quickly. The diffcut events of the past few weeks might well have been even more tragic without their action. We appreciate the doe coordination and collaboration we have with state and county Offices of Emergency Services, wheich help to idensify vuinerable customers and critical service providers, We also are gratelul for the women and men of SCE-many ably represented by iBEW Local 47-who work tirelessy to keep our communities safe and to make our system strong. To our dedicated employees-thank you At SCE, safety is our most important value, and we will continue to do what is needed to operate the electric syszem safely and reliably Pedro 1.
