PG&E Files 10-Year Electrical Undergrounding Plan to Deliver Permanent Wildfire Protection and Improve Safety, Reliability and Affordability
PG&E estimates approximately $6 billion in avoided maintenance and vegetation-management costs over the underground assets' lives.
Sentiment and the balance of points
Rhea-AI Sentiment reads the wording of the document, how positive or negative its language is on a 1 to 5 scale. The balance of points shown with the takes weighs what the document actually discloses, so the two can disagree, for example when a trial that missed its main goal is described in upbeat language.
Rhea-AI Summary
PG&E (PCG) filed a proposed 10-year plan to underground approximately 5,000 miles of electric distribution lines from 2028 to 2037.
The work would span more than 30 Northern and Central California counties. PG&E estimates long-term benefits of $117 billion, more than 10 times the proposed investment, and approximately $6 billion in avoided vegetation management, operations and maintenance costs over the assets' lives. It forecasts nearly 98% lower ignition risk and 90% fewer outages on lines moved underground.
Undergrounding cost per mile has fallen approximately 25% over the last few years. Energy Safety approval remains pending; if approved, PG&E will seek conditional cost approval from the California Public Utilities Commission. Subject to regulatory approval, PG&E expects to underground or upgrade more than 11,000 miles in high wildfire-risk areas by the end of 2037.
How this balance works
Rhea-AI gives every point it takes from this document a weight. Minor counts 1, Moderate 3 and Major 9, so one Major point outweighs several Minor ones. The bar adds up the weights on each side, and when neither side holds more than 65% of the total the balance reads Mixed.
It reads the document as published, with the same rules for every company, and it does not look at what the market expected or at how the stock traded, so a point can be objectively good on a day the stock falls.
Rhea-AI Sentiment measures something else, the tone of the wording.

News Explained
The filing says PG&E’s risk model weighs wildfire risk, reliability, customer effects and project costs against other mitigations; where undergrounding is not the best fit, the company may instead strengthen poles, cover lines or make other overhead upgrades.

Proposed 5,000-mile plan, spanning more than 30 counties, would reduce wildfire ignition risk by
The proposed plan would place approximately 5,000 miles of electric distribution lines underground from 2028 to 2037 in locations where undergrounding is forecasted to provide the greatest reduction in wildfire risk. In these areas, undergrounding powerlines can reduce ignition risk by nearly
PG&E estimates that completing 5,000 miles of undergrounding will also save customers approximately
"Placing powerlines underground provides the most effective way to reduce wildfire risk and enhance reliability for customers within High Fire-Threat Districts," said Peter Kenny, PG&E Chief Delivery Officer and Electric Transmission and Distribution Senior Vice President. "A 10-year plan allows us to develop and execute projects with increased efficiency, which translates into cost savings for customers, all while delivering enhanced safety and reliability to the hometowns we are privileged to serve."
Benefits for Customers
The proposed 10-year plan is designed to deliver lasting benefits, including:
- Improved safety: Undergrounding permanently reduces wildfire risk by
98% on lines moved underground. - Fewer outages: Customers served by underground lines experience enhanced reliability, resulting in approximately
90% fewer outages. - Protection for critical facilities: Undergrounding can also improve reliability for critical facilities such as hospitals, fire stations, police stations and other essential community services.
- Lower long-term costs: PG&E estimates that completing 5,000 miles of undergrounding will allow the Company to avoid approximately
$6 billion - Unlocked investments: PG&E will continue to develop and test new technology and processes that have already reduced the undergrounding cost per mile by approximately
25% . - Better planning and coordination: A 10-year roadmap provides greater certainty and coordination with customers, local agencies, suppliers, vendors and stakeholders.
Focused on Affordability and Disciplined Investment
PG&E estimates the plan will deliver long-term benefits valued at
Over the last few years, PG&E has reduced its undergrounding cost per mile by approximately
The proposal will be reviewed by Energy Safety, which will evaluate whether the plan substantially increases reliability and substantially reduces wildfire risk. If the plan is approved, PG&E will submit the plan and an application to the California Public Utilities Commission requesting conditional approval of the plan's costs.
Data and Technology Puts the Right Solution in the Right Place
A key feature of the plan is PG&E's use of advanced data analytics and risk modeling to forecast where undergrounding will provide the greatest benefits for customers and communities.
The company's risk-based approach considers wildfire likelihood and consequence, system reliability, customer impacts, project costs and benefits, and how undergrounding compares with other wildfire mitigations.
When undergrounding is not the best fit for a given location, PG&E may deploy other system upgrade measures, including installing strengthened poles, covered powerlines and other overhead system upgrades. This approach helps direct investments toward the solutions that provide the greatest overall value to customers while maintaining a strong focus on safety and reliability.
Building on Proven Progress
By the end of 2027, PG&E plans to have completed more than 1,900 miles of undergrounding and approximately 2,000 miles of overhead system upgrades in high wildfire-risk areas, since the programs started. Combined with the proposed 10-year EUP mileage and additional overhead system upgrade work, PG&E expects to underground or upgrade more than 11,000 miles of powerlines in high wildfire-risk areas by the end of 2037, subject to regulatory approval.
"Our customers deserve safer, more reliable energy service at the lowest possible cost," said Matt Pender, Undergrounding & System Hardening Vice President. "This plan continues our progress in delivering exactly that, making long-term investments that reduce wildfire risk, improve reliability and create savings over time."
