A second blade breakage has occurred at the 372MW Bjornberget onshore wind farm in Sweden, with the failure detected on January 7. This incident follows a similar event just two months prior, when a blade broke off one of the 60 Siemens Gamesa turbines during November 2024.
Key Incident Information:
- Turbine Shutdown: Following the latest breakage, RES, the company managing the technical and commercial operations of the wind farm, has shut down 51 of the 60 SG 5.8-170 turbines. A cleanup operation has been initiated to address the debris scattered across the site [1].
- Safety Measures: RES confirmed that the area has been secured and reported no injuries from the incident. Preliminary inspections indicate that the blade broke near the root while the wind farm was operational at the time [1].
- Operational Continuity: Despite the shutdown, nine turbines are still functioning, as they are equipped with blades sourced from a different manufacturing facility, allowing for partial operations during the ongoing investigation [1].
Investigation Timeline:
The investigation into the cause of the blade breakage is expected to take at least four weeks, with no current timeline for the reinstatement of the remaining turbines. A RES spokesperson stated, “We are eager to get the wind farm up and running again, but we have to put safety first” [1].
Additionally, the investigation into the November blade breakage is still in progress. A replacement turbine unit has been delivered but has not yet been installed [1].
Ownership and Background:
Bjornberget wind farm began operations in 2022 and is jointly owned by Prime Capital and Enlight, located approximately 10km southeast of Ange. Siemens Gamesa has been approached for comments regarding the recent incidents [1].
