French developer Engie has put 19 turbines on standby at an unnamed wind farm in Latin America to allow Siemens Gamesa to investigate issues detected with the equipment.
It said the manufacturer requested the intervention in early July after “anomalies” were identified on the machine drivetrains.
The affected models were not specified.
Remediation works are in progress and Siemens Gamesa is now finalising a Root Cause Analysis (RCA), an Engie spokesperson confirmed.
“Siemens Gamesa turbines share of our wind fleet is limited and their performance is in line with that of other equipment manufacturers,” they added.
“Since their announcement, they have shared the technical information that was available but this remains limited until they have achieved their root cause analysis on the technical issues.
“We are following this closely with them to correct any potential defects, should they be confirmed.”
Siemens Gamesa was unable to share any further details of the situation.
Engie added a separate RCA is being carried out by Siemens Gamesa linked to a problem with a single turbine at a different wind farm in Latin America.
The company did not identify the affected project.
In July, it was reported that investigations were ongoing into a broken turbine blade at Engie’s Santo Agostinho wind farm in Brazil where hardware from Siemens Gamesa’s 5.X platform is being installed.
