In addressing the wildfire challenges in high fire risk areas, our proposed 2020-22 Wildfire Mitigation Plan (WMP) outlines areas of exploration and application of a variety of innovative, new technologies that can be used to predict and prevent equipment failures that could spark fires. For a summary of the 2020-22 Wildfire Mitigation Plan, see this fact sheet.
We’re reinforcing our grid by replacing current equipment with new technologies that help reduce wildfire risks, including:
- Insulated wires that lower the chance of faults or short circuits that can create sparks when they come into contact with animals, vegetation, or other debris.
- Composite poles that are stronger and more resilient than wood poles.
- Fast-acting fuses, advanced lightning arrestors, and other devices that can react more quickly to minimize fire risks.
We’re proactively working to identify trees and other vegetation that may pose a risk to power lines in fire-prone areas. We’ve increased the frequency of our vegetation patrols and inspect over 1 million trees annually. We prune nearly 750,000 trees per year and remove dead, diseased or dying trees in our service territory. Our teams are also monitoring trees outside required clearances that may pose a potential risk to the company’s power lines.
We’ve invested in a number of ways to better forecast potential wildfire conditions and be more effective in responding to fire events when they occur.
Our Situational Awareness Center is staffed around the clock with meteorologists and Geographic Information System (GIS) professionals during events and incidents. Our new high-resolution weather data maps will help our meteorologists identify future extreme conditions.
We’ve installed additional weather stations that provide real-time information about wind, temperature, and humidity to help us make key decisions during potential fire conditions, including Public Safety Power Shutoff (PSPS) events.
Our live fire monitoring cameras will help our incident command teams and first responders more quickly assess and respond to reported fires.
Our fire management team works with fire agencies throughout our service territory to:
- Improve service reliability during critical incidents
- Support public and firefighter safety
- Foster relationships that improve response times
