Wildfire Mitigation Program

Chelan PUD has a comprehensive Wildfire Mitigation Program in place to protect communities and increase the resiliency of the electrical grid. We continue to build upon this program as we learn more about wildfire risk in Chelan County, and adapt to changing conditions. 

Chelan County is a geographically diverse place with forested mountains, wetlands and shrub-steppe foothills. The tools we use to address wildfire risk are area-specific and backed by detailed fire risk studies and industry best-practices.
 

Chelan PUD's Wildfire Mitigation Program includes an array of tools, including:

  • Tree-trimming and brush removal
  • Fire-retardant treatments
  • Replacing wood with steel poles
  • Undergrounding lines where feasible
  • Equipment maintenance and upgrades
  • Increasing the sensitivity of fire protection systems
  • Increased inspections during fire season
  • Coordination with local agencies
  • Public Safety Power Shutoff

Vegetation Management

Chelan PUD's Vegetation Management Program is designed to prevent trees or other vegetation from coming into contact with utility lines. The PUD routinely inspects, prunes and/or removes vegetation that encroaches on utility lines. PUD arborists can help customers evaluate the power lines on their property and choose the correct trees for that area. Learn more about the program here.

Fire Hardening Projects

Fire hardening projects are improvements that will help prevent power outages due to fire activity, shorten the duration of an outage after a wildfire, and improve the resiliency and reliability of the PUD’s electrical system.

These projects may include:

  • Rerouting power lines out of high fire risk areas
  • Converting overhead distribution to underground where feasible
  • Applying fire retardant paint to wood poles
  • Upgrading poles from wood to steel
  • Replacing aging infrastructure
  • Installing animal guards


Fire hardening projects are included in our annual capital improvement program. Learn more about current capital improvement projects here.

Chelan Transmission Fire Hardening Project

In 2021, Chelan PUD completed a wood-to-steel conversion of the transmission lines that serve the Lake Chelan Valley. Replacing wood poles with steel poles will allow fires to pass by and leave the line intact.

Public Safety Power Shutoff

A public safety power shutoff (PSPS) is a proactive power outage designed to prevent wildfire ignitions from utility infrastructure during very high winds and dry conditions. We know the devastation that wildfires can have on a community, and we also recognize the impact on our customers when power is out. The decision to use a PSPS is one we take very seriously and is a rarely used measure of last resort. Learn more about public safety power shutoffs here.
