Predicted strong, dry northerly winds mean PG&E may need to proactively shut off power for safety reasons About 28,000 customers in several counties as of Thursday

Pacific Gas and Electric Company (PG&E) meteorologists and operations experts are monitoring a potential wind event that is expected to enter portions of our service area around noon Thursday and not exit until midday Saturday. Given forecast high winds and current dry vegetation conditions, PG&E has begun sending enhanced notifications to customers – via text message, email and automated phone call – in certain areas where power may need to be proactively shut off for safety reasons Reduce the risk of forest fires. The duration and extent of power outages depend on the weather in each region and not all customers will be affected throughout the period.

The potential Public Safety Power Shutoff (PSPS) event could affect approximately 28,000 customers in small portions of several counties, including areas in the North Bay, East Bay, Central Coast and Sierra Nevada. PG&E's internal meteorologists, Emergency Operations Center and Hazard Awareness & Warning Center (HAWC) continue to closely monitor conditions and will share additional customer notifications as conditions continue to develop.

When possible, PG&E representatives will conduct individual, in-person visits with customers who are participating in the company's Medical Baseline Program and cannot demonstrate that they have received these important safety notices, with a particular focus on customers requiring critical life support equipment rely on electricity.

Why PG&E is declaring a PSPS event

PG&E initiates PSPS when the fire weather forecast is so severe that wildfires could threaten people's safety, lives, homes and businesses. Our overall goal is to prevent catastrophic wildfires by proactively turning off power in targeted areas when extreme weather conditions threaten our electrical grid. We recognize that PSPS outages create stress for our customers and communities. Our sole focus is the safety of our customers.

Because every weather situation is unique, we carefully consider a combination of factors when deciding whether to turn off the power. These factors include, but are not limited to:

• Low humidity, generally 30% and less.
• Strong winds are forecast, particularly sustained winds over 19 mph and gusts over 30-40 mph.
• Condition of dry material on the ground and low moisture content of vegetation.

Our decision-making process also takes into account the presence of trees tall enough to hit power lines.

This set of criteria is a first step that may lead to further analysis by our meteorology team to determine whether a PSPS event is necessary.

PG&E's commitment to wildfire protection

By using advanced technologies and rebuilding the electrical system from the ground up, we prevent wildfires, improve reliability and reduce costs in the long term. We are building the future energy grid our customers deserve, while taking immediate action to keep our customers safe.

Our wildfire prevention work relies on layers of protection that make our system safer and more resilient while enabling us to better serve our customers in the short and long term. These tools help us respond to our state's evolving climate challenges:

• Our 10,000-mile underground construction program is the largest effort in the U.S. to lay power lines to reduce the risk of wildfires.
• In addition to undergrounding, we are reinforcing the power grid with stronger poles and covered power lines in and near high fire risk areas.
• Advanced Powerline Safety Settings (EPSS) reduce the number of ignitions and provide wildfire protection for all customers living in high fire risk areas.
• We continue to reduce the impact of PSPS. Although there were no weather-related PSPS outages in 2022, this remains the focus of our team.
• We manage trees and other plants near power lines that could cause a power outage and/or ignition.

We are also investing in advanced tools and technologies such as artificial intelligence and drones to help us automate fire detection and response.
