On Monday evening 8 September, a wind turbine at the ECN Wind Energy Facilities (EWEF) test site in Wieringerwerf, in the province of Noord-Holland, caught fire.
A spokesperson for German wind turbine manufacturer ENERCON confirmed to Windpowernl that it concerned their E-160 EP5 wind turbine.
The fire started late evening (local time) in the vicinity of the machine house following a yellow weather warning of heavy rain and thunderstorms.
According to the spokesperson, no persons were harmed in the incident. It resulted only in property damage at a scale as yet unknown. A large area has been blocked off around the wind energy converter site and the fire brigade was alerted.
ENERCON, as the operator and Wind Turbine Manufacturer, immediately initiated a root cause analysis to investigate how the fire may have started.
The EWEF wind test facilities was founded by Dutch research company ECN but was acquired in 2020 by CIC EWEF B.V, a dutch subsidiary of Hamburg-based Connected Infrastructure Capital GmbH. The facility holds several prototype sites with a fully developed infrastructure and a total capacity of about 35 MW, which are leased to manufacturers to test their prototypes in order to obtain type certificates.
