US developer NextEra Energy Resources is investigating after a blade broke off a GE turbine this week at the 98.1MW Breckinridge wind farm in Oklahoma.
NextEra turbine monitors noticed the unit was not operating normally and went offline about 10pm on 31 May, spokesperson Bryan Garner told reNEWS.
No one was injured in the incident.
“Blade failures are very rare,” said Garner.
“We believe this was an isolated equipment issue, but we are inspecting each of the turbines at the wind farm to ensure they are operating normally,” he said.
The 51-turbine project features GE 1.7MW XLE machines. Breckinridge, located near Enid in Garfield County, started commercial operation in August 2015.
“We are working with the equipment manufacturer to provide a replacement blade,” said Garner.
