A crack in a steel tower is believed to have caused a wind farm turbine to topple over in Walkaway in June.

Iberdrola, the company responsible for the farm, launched a root cause analysis investigation after turbine 43 collapsed at Alinta Wind Farm nearly four months ago.

An Iberdrola spokesperson said the cause of the fallen turbine was due to a crack.

“Although the root cause analysis is yet to be finalised, we believe the cause of the failure was a crack in the turbine’s steel tower,” he said.

Iberdrola said the investigation was undertaken extensively and consulted industry experts, including Iberdrola’s global technical team, operations and maintenance providers.

“The entire plant has been inspected internally and externally, including detailed analysis of the steel towers,” the spokesperson said.

“Today, the wind farm is operating at near-full capacity and the failed turbine has been dismantled and removed. Four turbines require repairs before they can be returned to service, which will be carried out soon.”

The Walkaway site comprises 54 Vestas V82 wind turbines and generates enough renewable energy to power the equivalent of about 64,000 homes each year.
