Overstory: AI-Powered Vegetation Intelligence for a Resilient Electric Grid

What is the Overstory Project?

Overstory is all about AI-powered vegetation intelligence designed to create a more resilient electric grid. Vegetation is actually the single biggest cause of power outages and wildfires linked to the grid. This software helps utilities get smarter about managing their infrastructure by optimizing resources, mitigating vegetation risks, and future-proofing their operations programs. The end goal? Safer communities and smarter infrastructure management.

Main Benefits of Overstory’s Vegetation Intelligence

Here’s why data-driven vegetation management really matters:

• Rising Expenses: Vegetation management costs have jumped from 50% of overhead maintenance budgets in 2015 to 75% in 2020 — and they’re still climbing.
• Less Labor Availability: Over half (54.4%) of workers in vegetation management have voluntarily left their jobs in the last five years, plus the workforce is aging.
• Extreme Weather: Weather-related outages have surged by 78% over the past decade, with “outlier” days becoming more frequent.

How Overstory Optimizes Resources

Vegetation management is usually the biggest operations budget item for utilities, yet it’s often one of the least informed by advanced tech and analytics. Overstory helps maximize precious time and money by prioritizing the most impactful vegetation work. This means cutting down on unnecessary trimming while focusing efforts on riskier areas — smart spending, basically.

Reducing Risk and Improving Reliability

Vegetation risk keeps growing, especially with increasingly severe weather events. Reactive work? It’s getting more dangerous, expensive, and frequent. Overstory shifts the approach to proactive vegetation management — tackling encroachment, hazard trees, and wildfire risks before they become a problem. It’s about staying ahead of outages and disasters, not just reacting to them.

How the Technology Works

Overstory combines AI with remote sensing sources like satellite and aerial imagery to create detailed vegetation data. Then, it layers in local info — asset locations, wildfire maps, terrain, and more. This vegetation intelligence helps utilities build efficient, data-driven programs that make managing vegetation smarter and more predictable.

Impact on Sustainable Development Goals (SDGs)

• SDG 7: Affordable and Clean Energy — by improving grid reliability and reducing outages.
• SDG 9: Industry, Innovation, and Infrastructure — through advanced AI and remote sensing technologies.
• SDG 11: Sustainable Cities and Communities — by enhancing community safety from wildfire and power disruptions.
• SDG 13: Climate Action — by proactively managing vegetation risks linked to extreme weather and wildfires.
• SDG 15: Life on Land — by promoting sustainable vegetation management and protecting ecosystems.

Future-Proofing Operations with Overstory

With changing weather patterns, tight budgets, and a shrinking workforce, utilities can’t just rely on old vegetation management cycles or past experience anymore. Overstory helps build resilience and predictability into operations programs by codifying decision-making with data-driven insights. So, no matter what comes next — storms, heatwaves, or unexpected events — utilities are ready to respond smartly and efficiently.

What Overstory actually does

Overstory, formerly known as 20tree.ai, is a Lisbon-based startup founded in 2018 that uses AI and satellite imagery to help electric utilities manage vegetation risk near power lines, before it causes outages or wildfires. Instead of relying on scheduled inspection cycles, the platform flags exactly which trees and vegetation pose a real risk, letting utility crews target the highest-risk locations first.

“The results from Overstory are currently implemented in the vegetation management cycle for 10,000 miles of powerline.”

Where the vegetation intelligence shows up

• North American utilities: PG&E, AEP Texas, AEP Ohio, ComEd, Portland General Electric, BC Hydro, Hydro One, Eversource
• Rural electric cooperatives: Holy Cross Energy, Powder River Energy Corporation, Sho-Me Power Electric Cooperative, Central Virginia Electric Cooperative
• International grid operators: Red Eléctrica de España (Elewit/REE Group)

Proof, not just claims

Central Virginia Electric Cooperative also reported a reduction in fall-in-related outage rates (SAIDI) from roughly 94% to around 70% after adopting the platform.

Why this belongs on a sustainability directory

By reducing vegetation-caused power outages and wildfire risk before they happen, Overstory’s technology addresses a growing climate-adaptation problem head-on. Weather-related outages have risen roughly 78% over the past decade, and its work sits squarely inside SDG15 (life on land), since precise, AI-guided vegetation management reduces both unnecessary tree removal and the wildfire risk that comes from unmanaged vegetation near infrastructure.
