Hardening the grid, reducing risks
Weather is one of the biggest concerns for electric utilities, and in recent years, the changing climate has made extreme weather events increasingly common.
Conditions on the ground are changing, and so are our plans and responses. We’re investing $2.5 billion across our six-state system in wildfire mitigation strategies over the coming years. With advanced capabilities in round-the-clock weather monitoring and vegetation management, we’re advancing safety today and building resilience and reliability for years to come.
What is grid hardening?
Line rebuild
Replacing aging overhead power lines in fire high consequence areas (FHCA) with fire-resistant infrastructure, such as covered conductors or underground systems, to enhance reliability and significantly reduce the risk of equipment-related wildfires.
Relays, breakers and field recloser upgrades
Upgrading protective devices like relays and reclosers to ensure faster and safer detection of faults, minimizing the chances of sparks that could ignite wildfires.
Expulsion fuse installation
Replacing traditional fuses with non-expulsion fuses that eliminate sparks during operation, significantly lowering the fire risk from electrical equipment.
Weather station installation
Deploying advanced weather stations to monitor real-time conditions like temperature, humidity, and wind, enabling proactive adjustments to wildfire prevention measures.
How we're increasing safety and resilience
Hardening our infrastructure
Fire-resistant poles, covered lines and undergrounding where appropriate are just part of the story. We’re also installing advanced technology that enables real-time monitoring, remote management and more.
Data science for a safer grid
We are integrating advanced technology—including a meteorology and data science team—to deliver your power safely in all weather.
Real-time monitoring
We’re putting big data to work for a resilient system with a combination of enhanced situational awareness and new meteorology tools and teams for forecasting how weather will impact the system.
Increased vegetation management
We're using aerial and ground patrols to identify potential hazards, removing trees before they can come into contact with lines, expanding vegetation clearance around poles and more.
