Community Wildfire Safety Program •Further enhancing vegetation management efforts to increase focus on vegetation that poses a higher potential for wildfire risk •Conducting accelerated safety inspections of electric infrastructure in high fire-threat areas •Disabling automatic reclosing of circuit breakers and reclosers in high fire-risk areas during wildfire season •Proactively turning off electric power for safety (Public Safety Power Shutoff) when extreme fire danger conditions are forecasted NEW AND ENHANCED SAFETY MEASURES •Installing stronger and more resilient poles and covered power lines, along with targeted undergrounding •Upgrading and replacing electric equipment and infrastructure to further reduce wildfire risks •Working with communities to develop new resilience zones to provide electricity to central community resources during a Public Safety Power Shutoff event SYSTEM HARDENING AND RESILIENCY •Coordinating prevention and response efforts by monitoring wildfire risks in real time from our Wildfire Safety Operations Center •Expanding our network of PG&E weather stations to enhance weather forecasting and modeling •Supporting the installation of new high-definition cameras in high fire-threat areas REAL-TIME MONITORING AND INTELLIGENCE 3 Following the wildfires in 2017 and 2018, some of the changes included in this presentation are contemplated as additional pr ecautionary measures intended to further reduce future wildfire risk.

PG&E’s service area includes more than 100 million trees with the potential to grow or fall into our overhead power lines Inspects approximately 100,000 miles of overhead power lines Prunes or removes approximately 1.4 million trees annually Addresses dead and dying trees in areas affected by drought and bark beetles Our Vegetation Management Program 5 Following the wildfires in 2017 and 2018, some of the changes included in this presentation are contemplated as additional pr ecautionary measures intended to further reduce future wildfire risk. Enhanced Vegetation Management For illustrative purposes only We are expanding and enhancing our Vegetation Management program to further reduce wildfire risk •Our enhanced vegetation management work includes the following: Meeting and exceeding state standards for minimum clearances around the power line Addressing overhanging limbs and branches directly above and around the lines Removing dead and dying trees as well as specific tree species that have more frequently fallen into PG&E lines and caused an ignition •We are working to complete this important safety work in high fire-threat areas over the next several years 6 Following the wildfires in 2017 and 2018, some of the changes included in this presentation are contemplated as additional pr ecautionary measures intended to further reduce future wildfire risk. Public Safety Power Shutoff (PSPS) We monitor conditions across our system and evaluate whether to proactively turn off electric lines for safety when extreme fire danger conditions are forecasted. While no single factor will drive a Public Safety Power Shutoff, some factors include: A RED FLAG WARNING declared by the National Weather Service LOW HUMIDITY LEVELS generally 20% and below FORECASTED SUSTAINED WINDS GENERALLY ABOVE 25 MPH AND WIND GUSTS IN EXCESS OF APPROXIMATELY 45 MPH, depending on location and site-specific conditions such as temperature, terrain and local climate CONDITION OF DRY FUEL on the ground and live vegetation (moisture content) ON-THE-GROUND, REAL-TIME OBSERVATIONS from PG&E’s Wildfire Safety Operations Center and field observations from PG&E crews 7 Following the wildfires in 2017 and 2018, some of the changes included in this presentation are contemplated as additional pr ecautionary measures intended to further reduce future wildfire risk. Public Safety Power Shutoff (PSPS) Source: California Public Utilities Commission •Beginning with the 2019 wildfire season, we are expanding our Public Safety Power Shutoff program to include all electric lines that pass through high fire-threat areas –both distribution and transmission. •The most likely electric lines to be considered for shutting off for safety will be those that pass through areas that have been designated by the CPUC as at elevated (Tier 2) or extreme (Tier 3) risk for wildfire. •Because the energy system relies on power lines working together to provide electricity, any of PG&E’s more than 5 million electric customers could have their power shut off. 8 Following the wildfires in 2017 and 2018, some of the changes included in this presentation are contemplated as additional pr ecautionary measures intended to further reduce future wildfire risk. PSPS Event Notifications Timing of Notifications (when possible) ~48 HOURS before electricity is turned off Extreme weather threats can change quickly. Our goal, dependent on weather, is to provide customers with advance notice prior to turning off power.We will also provide updates until power is restored. ~24 HOURS before electricity is turned off JUST BEFORE electricity is turned off DURING THE PUBLIC SAFETY OUTAGE ONCE POWER HAS BEEN RESTORED City/County/Agency Notifications We will make every attempt to provide notice in advance of notifying customers through: •Phone calls/emails to primary contacts •Automated notifications to send alerts through multiple channels •Provide customer alerts to share via channels, such as city or county website, Nixle, Nextdoor and Reverse 911 Customer Notifications We will attempt to reach customers through calls, texts and emails. We will also use social media and keep local news and radio outlets informed and updated. ! 9 Following the wildfires in 2017 and 2018, some of the changes included in this presentation are contemplated as additional pr ecautionary measures intended to further reduce future wildfire risk. Working to Restore Power WEATHER ALL CLEAR PATROL & INSPECT ISOLATE & REPAIR DAMAGE RESTORE POWER NOTIFY CUSTOMERS After the extreme weather has passed and it’s safe to do so, our crews begin patrols and inspections. Crews visually inspect our electric system to look for potential weather-related damage to the lines, poles and towers. This is done by vehicle, foot and air during daylight hours. Where damage is found, crews work to isolate the area so other parts of the system can be restored. Crews work safely and as quickly as possible to make repairs. Once it is safe to energize, a call is made to the PG&E Control Center to complete the energization process. Power is then restored to customers. Customers are notified that power has been restored. We will only restore power when we are certain it is safe to do so. We expect to be able to visually inspect the system for damage and restore power to most of our customers within 24 to 48 hours after extreme weather has passed. Because extreme weather can last several hours or days, for planning purposes, we suggest customers prepare for outages that could last longer than 48 hours. 10 Following the wildfires in 2017 and 2018, some of the changes included in this presentation are contemplated as additional pr ecautionary measures intended to further reduce future wildfire risk.
