PG&E Hits 1,500 Miles of Underground Lines as CPUC Threatens Plan
OAKLAND – November 10, 2026 -- Pacific Gas and Electric Company (PG&E) has installed and energized 1,500 miles of underground power lines in high fire-threat districts since launching its undergrounding program in 2021, cutting wildfire ignition risk on those lines by approximately 98%.
Customers served by the underground lines also experience approximately 90% fewer outages, according to the utility.
CPUC proposed decision would cut PG&E's eligible undergrounding from 5,000 to about 1,100 miles
The milestone arrives as the California Public Utilities Commission (CPUC) weighs a Proposed Decision in the SPD-37 Joint IOU Application proceeding. If adopted, it would reduce eligible undergrounding in PG&E's plan from 5,000 miles to approximately 1,100 miles. PG&E says this would hinder permanent risk reduction in the areas of highest wildfire vulnerability.
