Wind turbine fire sparks 500-acre wildfire near Bickleton, Washington

A wind turbine malfunctioned and caught fire near Bickleton in southern Washington state, igniting a wildfire that spread through the Pine Creek Drainage area, according to officials. The blaze, named the Juniper Fire, burned roughly 500 acres. Klickitat Fire District 2 was first on scene and kept the fire contained within the drainage area south of Bickleton. About 120 firefighters were working the blaze according to the state's Southeast Washington Interagency Incident Management Team, and the fire was around 20 percent contained on the Sunday morning. A night crew was dispatched to monitor the fire overnight and allow daytime crews to rest. The incident management team warned of continued hot weather and low humidity in the following days. Injuries and damage to the turbine or wider site were not reported.

Officials attributed the ignition to a wind turbine that malfunctioned and caught fire. Hot, dry conditions with low humidity and dry grasses in the surrounding area were cited by the incident management team as raising wildfire risk. The specific failure mode within the turbine was not reported.

1. A turbine fire can ignite surrounding vegetation within minutes in hot, dry conditions, so vegetation management and firebreaks around turbine bases matter as much as turbine protection itself.
2. Fast attendance by local fire districts can hold a turbine-sparked fire within a limited area, which depends on site access routes and accurate location information being available to responders.
3. Operators of turbines in wildfire-prone rural areas should agree communication and coordination arrangements with regional fire and land management agencies before the fire season.
4. Seasonal fire risk assessments should consider curtailment or heightened monitoring of turbines during periods of high temperature and low humidity.
