Decision IntelPacific Gas and Electric
PG&E Camp Fire Liability
Estimated impact: $13.5B
PG&E's failure to maintain aging transmission infrastructure caused the Camp Fire, the deadliest and most destructive wildfire in California history. The fire killed 85 people and destroyed 18,804 structures. PG&E had deferred maintenance and vegetation management for years despite knowing its equipment posed wildfire risks.
Decision context
Whether to invest in replacing aging transmission lines and aggressive vegetation management in high-risk wildfire zones, or to continue deferring maintenance to reduce operating costs.
What the company’s own filing already carried
Not our reading of a memo. Pacific Gas and Electric's own 10-K, filed 2017-02-16 (11 months before the 2018 decision), was read by the audit engine's deterministic structural layer: the same detectors that run on every audit, with no language model involved. Everything below is drawn from the company's own disclosure, before any knowledge of what followed, and never from the decision itself.
Would not absorb the hit: if the flagged risk fires, nothing disclosed in the structure would materially absorb that loss.
- Commodity-price-linked cash flowsunprotected
- This reads the company's own 10-K (filed 11 months before the decision), not the decision memo itself, so it can only understate what a full audit of the memo would surface.
- It reads the structure of the situation, not the trigger: whether a shock to the flagged conditions would be absorbed, never that a shock arrives.
- A reading of a dated filing, not a prediction: every condition can be checked against the company's own 10-K.

The curated library this case sits in
Across all 155 curated case studies in our library, by documented outcome:
The library is curated toward documented failures, so this split describes the library, not the base rate of deals. The case above is one row in it.
Lessons learned
- Status quo bias in infrastructure maintenance means deferred spending accumulates as hidden risk until catastrophic failure.
- Cognitive misering in risk assessments leads utilities to treat wildfire risk as a low-probability event rather than updating for climate change.
- Loss aversion around short-term earnings prevents the capital investment needed to prevent long-term catastrophic losses.
