A second blade breakage incident has occurred at the 372MW Bjornberget onshore wind farm in Sweden, following a similar event in November 2024. The failure, which was discovered on January 7, involves one of the Siemens Gamesa SG 5.8-170 turbines at the facility. This marks the second blade failure at the site in a span of two months.
RES, which handles the technical and commercial operations of the wind farm, confirmed that 51 of the wind farm's 60 turbines were shut down as part of a precautionary measure. A clean-up operation is underway to address the scattered debris from the broken blade. An investigation into the cause of the breakage has also begun.
A spokesperson for RES stated: “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).
Initial inspections suggest that the blade broke near its root while the wind farm was operational at the time of the failure. However, RES has been able to continue operations with nine turbines at the site, as they are equipped with blades sourced from a different factory.
The investigation into the cause of the latest breakage is expected to take at least four weeks, and there is currently no set timeline for when the remaining turbines will be operational again. “We are eager to get the wind farm up and running again but we have to put safety first,” the spokesperson added.
RES also confirmed that the investigation into the blade failure in November is still ongoing. A replacement turbine unit has already been delivered to the site, but it has not yet been installed.
Bjornberget is jointly owned by Prime Capital and Enlight and is located 10 km southeast of Ange. The wind farm began operations in 2022. Siemens Gamesa has been contacted for comment on the incidents.
