Vestas says it is still investigating what caused one of its V112-3.0 MW wind turbines to catch fire on March 30.

This investigation involves Vestas experts and two external experts inspecting the nacelle and modeling possible root causes. On-site, initial close inspections of the burnt turbine from height - using both a crane and a drone aircraft with a camera - have assisted in the investigation, the company explains.

Vestas is in the process of taking down the burnt turbine, which will lead to a closer on-the-ground inspection within days, the company says, adding that planning is under way to replace the burnt turbine.

In addition, as a part of the investigation, and in close communication with relevant customers, Vestas has paused other V112 turbines with a similar production configuration to the turbine that caught fire.

“We are confident that we are getting closer to the root cause of the fire, and we are now returning the paused turbines back to normal operation one by one after having completed a thorough inspection and implemented upgrades, including new software to mitigate the issues found as part of the root-cause investigation,” the company said in a statement. “We expect that all of the paused turbines will be returned to normal operation by late April.
