THE PROBLEM

The natural world around the grid is constantly changing. Calendar-based trimming can't keep up.

Our platform

The depth of a single tree.
The breadth of your entire network.

Trained across millions of miles and billions of trees, Overstory’s AI-driven
platform lets you compare high risk circuits and rank your spans, so every
level is connected.

Why overstory

The enterprise platform
that turns risk into action

Accuracy at the scale of action

Current-year imagery, proprietary models and arborist validation reveal risks from the network down to the tree.

Risk in business terms

Scenario modeling weighs risk, cost and operational
impact so leaders can compare paths and prove the
validity of decisions to leadership and regulators.

Experience with programs like yours

Drawing on work with 6 of the 10 largest North American
utilities, Overstory’s arborists, fire scientists and program
experts turn analysis into programs that work.

How utilities are reducing more risk with every dollar

Four key ways utilities are transforming how they manage vegetation risk

Optimize your maintenance program

Pull urgent work forward and push low-value work out, tackling more outage risk with the same resources.

Create targeted programs

Find the spots in your network driving outsized risk. Build focused hazard-tree, storm or mid-cycle programs around them, each with a cost and outcome you can justify.

Estimate work before the bid

Give contractors a sharper scope and catch inflated estimates before they reach the budget.

Defend every decision

Show leaders and regulators where the risk sits, what the program is changing and why the next dollar should go where you propose.

With this intelligence, at the click of a button, we could see our entire service territory and plan our work for the areas of high risk.

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.

CEO, Holy Cross Energy

Now, instead of looking for the proverbial needle in a haystack, we have data on what’s a problem and what we need to address.

Construction Engineering and Operations Director, Sho-Me

Overstory and Watch Duty deliver a shared, real-time view of vegetation hazards that could ignite or accelerate wildfire spread, allowing them to take action before that risk becomes an emergency.

Andy Abranches
Vice President of Wildfire Mitigation, PG&E

Now I can look at the entire system at once, clearly see what's diverting risk, and make informed, measurable decisions.
