PG&E's Groundbreaking 10-Year Electrical Undergrounding Plan

Pacific Gas and Electric Company (PG&E) has made a significant move by filing a proposed 10-Year Electrical Undergrounding Plan (EUP) with the California Office of Energy Infrastructure Safety. This ambitious plan is aimed at improving safety and reliability in areas prone to wildfires across Northern and Central California and promises long-lasting benefits estimated at a staggering $117 billion.

A Revolutionary Approach to Fire Safety

Set to be implemented from 2028 to 2037, the EUP will involve burying approximately 5,000 miles of electric distribution lines. This initiative is forecasted to reduce the risk of wildfire ignitions by an impressive 98% in areas targeted for this transformation. More importantly, customers in these regions can expect a dramatic decrease in outages, potentially down by 90% once the underground lines are in place. Such a reduction in outages will enhance the reliability of power delivery, benefitting everyday life significantly.

PG&E envisions that this transition will save customers around $6 billion in vegetation management and maintenance costs throughout the lifespan of these underground assets. This forward-thinking initiative includes work across more than 30 counties in California, reflecting PG&E’s commitment to addressing the pressing issue of wildfire hazards head-on.

Key Benefits of the Electrical Undergrounding Plan

The proposed plan is structured to deliver several lasting advantages:

1. Enhanced Safety: The undergrounding of existing lines will drastically minimize the risk of wildfires, offering permanent safety improvements for communities at risk.
2. Fewer Outages: Customers will experience significantly improved reliability, enjoying approximately 90% fewer outages, which is vital for daily operations and peace of mind.
3. Security for Essential Services: Critical facilities such as hospitals, police stations, and fire departments will benefit from improved reliability, allowing them to function more effectively.
4. Cost Efficiency: PG&E’s projections indicate that the undergrounding project will mitigate approximately $6 billion in future vegetation management, streamlining operations and reducing expenses.
5. Innovative Investments: Ongoing technology development is expected to decrease undergrounding costs by about 25%, leading to better investment efficiency.
6. Better Coordination: A structured 10-year strategy allows for greater planning and collaboration with local agencies, stakeholders, and the communities served.

Strategic Focus on Long-term Outcomes

PG&E anticipates that its robust plan will result in monumental benefits, calculated at more than tenfold the investments made, while also eliminating future expenses related to maintenance and vegetation management. As the company continues to lower their undergrounding costs per mile, it aims to enhance efficiency and efficacy in line installation.

A unique aspect of the EUP is PG&E's integration of advanced data analytics and risk modeling. This data-driven approach ensures that the company can pinpoint locations where undergrounding will yield the greatest advantages for customers and communities, further optimizing resource allocation.

Prioritizing Safety and Reliability in Project Execution

In situations where undergrounding may not be the ideal solution, PG&E is prepared to implement several system upgrade initiatives, including stronger poles and covered powerlines, demonstrating a tailored strategy to maximize safety and customer satisfaction.

By the end of 2027, PG&E aims to have successfully completed over 1,900 miles of undergrounding and approximately 2,000 miles of system upgrades focused on high wildfire-risk areas. Anticipating approval, the company estimates that by the end of the proposed 10-year plan in 2037, it could have undergrounded over 11,000 miles of powerlines, shaping a safer future for communities across California.

Conclusion

As Matt Pender, PG&E's Undergrounding System Hardening Vice President, emphasized, “Our customers deserve safer, more reliable energy service at the lowest possible cost.” The proposed Electrical Undergrounding Plan is a bold step forward in ensuring that communities are protected against the increasing threat of wildfires, while also enhancing the overall quality and reliability of energy services in California.
