How does SUB prepare for wildfire events?
Most of SUB’s service territory is urban, which means a lower risk of wildfire. However, wildfires that approach Springfield have the potential of disrupting power and water services.
What you should know
Because Springfield is in a lower-risk area for wildfire, taking emergency action, such as de-energizing power lines, is unlikely. If we do need to de-energize part of our system, we will attempt to notify affected customers in advance; however, in a fast-moving situation, this may not be possible. SUB will always put your safety first.
What to watch for during fire weather
A Red Flag Warning is a weather forecast issued by the National Weather Service (NWS) to alert communities that conditions are ideal for wildfires to ignite. These warnings are typically issued when the following conditions are met:
- Strong Winds: High winds can rapidly spread wildfires by carrying embers over long distances.
- Low Humidity: Dry air can dry out vegetation, making it more flammable.
- High Temperatures: Hot temperatures can further dry out vegetation and increase the likelihood of ignition.
- Dry Fuels: Vegetation (such as grass, leaves, and branches) is dry and easily ignitable.
When these conditions coincide, the risk of wildfires starting and spreading increases significantly. Red Flag Warnings help authorities and the public prepare for potential fire outbreaks, taking necessary precautions to prevent fires and respond quickly if they do occur.
If a Red Flag Warning is issued for our service area, we encourage customers to use the opportunity to check their emergency supplies in the event conditions worsen. If you, or your friends or family, have medical needs that are met using electricity (such as medicines that require refrigeration, or devices that are electrically powered), be sure to have a plan for how to address a loss of power. Back up batteries and generators are common solutions and can provide peace of mind while we work to restore power.
As appropriate, SUB will provide information related to utility services on our social media channels and website.
How SUB keeps our system fire resistant
SUB’s comprehensive wildfire mitigation plan can be viewed here. In part, it covers:
System maintenance
SUB crews manage vegetation throughout the year by trimming trees, shrubs and removing potential hazards. This reduces the likelihood that limbs or branches will come into contact with power lines during severe wind and weather and helps maintain reliable power.
System review and investment
Regular engineering reviews of infrastructure allows SUB to determine if and when areas of our system require alternative protection methods. That could include actions like upgrading older equipment or burying overhead distribution lines in areas that have become more vulnerable to fire.
Operational practices
During fire weather, SUB takes many precautions, including adjusting work procedures to lessen ignition sources in high risk areas, carrying fire suppression equipment, and monitoring work areas after job completion to ensure the area is free of fire before leaving. If necessary, we can set our system sensitivity to a higher level so that protective equipment engages more quickly.
Emergency practices
In an extreme emergency, SUB has the ability to de-energize distribution power lines. This is a last resort and is taken when there is an immediate threat to life or property.
