A second blade breakage event has occurred at the 372MW Bjornberget onshore wind farm (pictured) in Sweden.
The failure was discovered on January 7 and comes just two months after a blade broke off another of the array’s 60 Siemens Gamesa turbines in November 2024.
A spokesperson for RES, which is responsible for the technical and commercial operation of the wind farm on behalf of the owners, told reNEWS that it has shut down 51 of the wind farm’s 60 SG 5.8-170 units and launched a clear-up operation of the scattered debris.
It has also started an investigation into the cause of the breakage.
The spokesperson said: “We have secured the area and concluded that no-one was injured. We are in a thorough process with the (turbine) supplier on what has caused another blade incident (at this site).”
The spokesperson said that the wind farm was operating at the time of the failure and that initial inspections indicate that the blade broke near the root.
They added that RES has been able to continue operating nine turbines at Bjornberget as they are equipped with blades from a different factory to the others.
The investigation into the breakage will take “at least four weeks”, according to the company, and there is currently no timeline for bringing the remaining units back into operation.
The spokesperson added: “We are eager to get the wind farm up and running again but we have to put safety first.”
A spokesperson from Siemens Gamesa told reNEWS: “On January 7, 2025, it was identified that a blade broke in the Bjoernberget wind park.
“No one was harmed and a safety zone has been established around the turbine.
“We are investigating the cause of this incident and are in constant communication with our customers, suppliers and local authorities to ensure safety for technicians and the public.”
The investigation into the blade breakage that occurred in November remains ongoing, RES told reNEWS.
A replacement turbine unit has been delivered to the project site but has yet to be installed.
Bjornberget is jointly owned by Prime Capital and Enlight and is located 10km south-east of Ange.
The wind farm started operating in 2022.
