THE PROBLEM

A fire can't spread without fuel.
Prevent the spark from becoming a disaster.

39%
39% of utility ignitions in high fire-risk areas are caused by vegetation in corridors.

Manage the risk you can control

By combining the industry’s most precise vegetation and fuel models with weather and asset data, Overstory identifies your highest risk and turns it into
a defensible decision you can act on.

Why overstory

Precision from
spark to spread

Your greatest hazards, mapped

For every span, Overstory shows the risk posed by assets, fuels, or vegetation to highlight where to work and what work to do.

Accuracy at the scale of action

We combine the industry’s most granular fuel data with best-in class vegetation insights to reveal exactly what’s driving risk and which action fits.

Evidence over estimates

Our scenario modeling weighs likelihood, consequence, cost and operational impact to inform wildfire mitigation plans, rate cases and regulatory requirements.

OUR SCIENCE

Powered by proprietary models

Built on the expertise of the industry’s largest forestry team and fire scientists, trained across millions of miles and validated in dozens of utility territories.

Fuel Detection Model

The only fuel base map built specifically for utility corridors, at the scale where ignitions actually occur.

Always refreshed with the latest imagery, Overstory can pinpoint the exact spans, assets and fuels that can prevent wildfires this season.

Most of our wildfire-related concerns come from the trees that fall into our right of way. Overstory helps us identify those trees and mitigate risk before they fall.
