Most utilities still lack the high-frequency, localized fault data needed to identify wildfire risk early. Methods such as manual patrols, helicopter inspections, and time-based vegetation management remain common in wildfire prevention, but these approaches are inherently reactive.
The financial and operational exposure is substantial. U.S. wildfires have caused more than $140 billion in damages since 2017, with utility liability exceeding $10 billion for a single event. As insurance capacity contracts and power shutoffs disrupt millions of customers, annual mitigation costs now range from millions per service territory to billions for major utilities.
Wildfire risk is difficult to manage when critical fault conditions remain invisible. Closing that visibility gap requires earlier detection, greater localization, and a clearer understanding of which grid conditions are most likely to lead to ignition.
The white paper, available below, explores what that shift looks like in practice - and where advanced sensing can make the greatest difference.
