AI/ML use cases for utilities to increase wildfire resiliency
August 09, 2024
Rising temperatures, drier conditions, and the spread of urban areas into fire-prone regions are forming a dangerous combination for wildfire surges. In 2023, the National Interagency Fire Center (NIFC) reported a staggering 56,580 wildfires that scorched over 2.6 million acres across the United States. Wildfires have become a relentless force of destruction, capable of incinerating entire communities with alarming speed and intensity. The devastating camp fire in California, which caused over $16.5 billion in damages, is a stark reminder of the havoc wildfires can wreak. These infernos not only annihilate homes and critical infrastructure but also degrade air quality, disrupt ecosystems, and impose staggering economic costs.
At a global scale, utilities are adopting innovative strategies through artificial intelligence (AI) and machine learning (ML) solutions to prevent and mitigate wildfire damage. By exploring wildfire mitigation use cases, we illustrate the breadth of potential with these technologies and propose considerations to help utilities evaluate and select the most suitable AI/ML solutions.

Remarkable analysis of immense geospatial data through AI technologies are revolutionizing fire risk modeling, predicting high-risk areas, and identifying patterns and correlations that traditional methods overlook. Advanced supervised and unsupervised learning algorithms integrate data from sensors and real-time sources such as temperature, humidity, wind speed, smoke levels, and vegetation density to generate detailed risk maps—helping utilities prioritize preventive measures and resource allocation.
Additionally, AI-enhanced weather forecasting provides hyperlocal predictions by leveraging ML algorithms to produce precise forecasts for specific areas. Integrating historical and real-time data offers accurate fire weather predictions, enabling utilities to anticipate and prepare for conditions that could elevate fire risks, informing smarter decisions and strategies to effectively mitigate wildfire threats.
Public Safety Power Shutoffs (PSPS) are preemptive measures taken by utilities to reduce the risk of wildfires during extreme weather conditions. When there’s a high fire risk—such as during strong winds, low humidity, and dry vegetation—power companies may turn off power in high-risk areas to prevent electrical equipment from igniting fires. AI analysis can optimize the timing and extent of power shutoffs by analyzing weather conditions, fire risk data, and grid status to determine the most effective timeframes and areas for fire prevention. Managing PSPS is a sensitive operation, balancing safety with minimizing disruption to customers and economic costs while also abating regulatory fines for the utility. AI offers the potential to increase the value of PSPS through improved accuracy, minimized disruptions, enhanced safety, and operational efficiency.
AI processes remote sensing, satellite, drone, and radar imagery to identify fire-risk vegetation. This is done by tracking growth and detecting vegetation clearance violations to conductors or other grid infrastructure components—enabling utilities to distinguish high-risk zones and prioritize vegetation management efforts. Models generated through supervised learning algorithms offer predictions of vegetation growth over time, allowing utilities to schedule proactive maintenance activities before vegetation becomes a fire hazard. These predictive growth models consider various factors such as species type, climate conditions, and historical growth patterns. AI utilized for vegetation maintenance significantly enhances safety by reducing the need for truck rolls and extensive fieldwork. By automating the detection and monitoring of vegetation risks, worker exposure to hazardous conditions is minimized, keeping them out of harm's way and ensuring a safer working environment.
Anomalies within the grid can indicate potential faults in utility infrastructure. Identifying these events is challenging because they often occur in remote areas, so by continuously monitoring data from sensors and equipment, AI-integrated systems can detect unusual patterns or deviations from normal operating conditions. For instance, an AI-powered anomaly detection system might identify a sudden spike in electrical resistance that could signal a failing component, enabling utilities to address the issue before it leads to a catastrophic failure or ignites a wildfire.
Accurately forecasting equipment failures by analyzing historical maintenance records and live performance data through AI models is a major logistics advantage. This allows utilities to proactively perform maintenance, reducing the risk of equipment-related fires, enhancing safety, extending infrastructure longevity, reducing operational costs, and optimizing procurement strategies.
AI optimizes electrical load distribution through dynamic load balancing, which helps prevent overheating and reduces the risk of fires. By continuously analyzing the demand and supply of electricity across the grid, AI systems can adjust the distribution of electrical loads in real time. This ensures that no single component is overloaded, thereby minimizing the risk of overheating and potential ignition sources.
AI-powered systems for automated FLISR enable quick fault identification and isolation. When a fault occurs, these systems can rapidly pinpoint the location, isolate the affected section, and reroute power to minimize service disruption. This swift response not only reduces downtime for customers but also mitigates the risk of faults escalating into larger fire hazards.
Utilities are leveraging AI simulations of wildfire scenarios for developing response strategies. AI creates detailed models of potential wildfire events to simulate various scenarios and outcomes, allowing emergency planners to evaluate different response strategies and optimize their plans based on simulated performance, ensuring that they are well-prepared for actual events.
AI provides real-time recommendations during fire events through advanced decision support systems. These systems analyze live datasets and use AI algorithms to generate actionable insights and recommendations for emergency responders. This real-time support can significantly enhance the response effectiveness, containing fires more quickly and minimizing damage.
To enhance infrastructure resiliency through AI, selection of the best solution requires a tailored approach. The decision-making process must account for impactful factors to ensure the chosen solution combines business value and feasibility, aligning operational goals, organizational capacity, and budgetary constraints.
AI solutions, particularly those aimed at enhancing wildfire resiliency, demand robust data storage capabilities due to the syphoning and computing of vast amounts of data from various sources. Utilities must assess their current data infrastructure to determine if it can handle the influx of data required for the AI to function effectively or consider third-party cloud solutions.
