PG&E Corporation | Pacific Gas and Electric Company 2025 Joint Proxy Statement 11

We have committed to making a “game-changing” investment in undergrounding power lines as a long-term solution to preventing wildfires. Since 2021 we undergrounded 875 miles. We are continuing our undergrounding in 2025, and with greater efficiencies and forecasted reduction in costs, we are on target to underground 1,000 miles between 2024 and 2026 (in alignment with the funding approved in PG&E’s 2023 General Rate Case). Our work is designed to focus on areas where undergrounding can have the greatest effect on reducing wildfire risk, while also improving reliability for customers.

A Game-Changing Commitment:
Miles of powerlines undergrounded or planned

The Enhanced Powerline Safety Settings (EPSS) program allows for automatic de-energization of distribution powerlines within 1/10 of a second if a fault occurs on the system that could trigger a wildfire ignition. For the safety of our customers and communities, we have enhanced safety settings on our powerlines that automatically turn off power within one-tenth of a second, or faster, if a wildfire hazard is detected. These settings are known as Enhanced Powerline Safety Settings, or EPSS, and they protect 1.8 million customers and approximately 44,000 powerline miles in and around high fire-risk areas.

When hazards contact powerlines, they can cause ignitions that can potentially lead to wildfires. Safety settings are in place to quickly turn off power when this happens and prevent ignitions. By stopping ignitions, we help prevent wildfires from starting and spreading.

Every year since the pilot of the EPSS Program in 2021, there has been a significant decrease in ignitions on powerlines protected by the settings. And again, we saw a 74% reduction in ignitions on powerlines protected by safety settings last year, despite a substantial increase in wildfire risk. 1

In previous years, we observed a decrease in the total high fire-threat district (HFTD) and high fire-risk areas (HFRA) acres burned relative to the pre-EPSS 2018-2020 three-year average. 2 We understand EPSS drives this decrease by reducing the amount of energy delivered to a fault location.

EPSS is a proven wildfire prevention technology and a critical part of our layers of
