Aging Wind Turbine Failure in South Korea Raises Safety Concerns
Table of Contents
A wind power generator over two decades old collapsed on Thursday afternoon in Yeongdeok-gun, Gyeongsangbuk-do, South Korea, prompting a precautionary shutdown of teh entire wind farm and raising questions about the aging infrastructure supporting the nation’s renewable energy goals. Fortunately, no injuries or property damage were reported as the turbine fell onto an unoccupied roadway.
Turbine Collapse and Initial Assessment
The incident occured around 4:40 PM local time at the Yeongdeok Wind Power Complex. Reporting from the scene, YTN’s kim Geun-woo described a scene of “utter destruction,” with debris from the 80-metre-tall turbine scattered across the area. The turbine’s blades, or wings, were found broken and the overall structure was “wholly destroyed.”
Initial investigations suggest the generator, which began commercial operation in 2005, exceeded its 20-year design lifespan. Local authorities believe the failure was initiated by a structural issue with a blade, which then impacted the main body of the turbine. Though, a key point of concern is that wind speeds at the time of the collapse – approximately 10.9 meters per second – were well below the threshold for a strong wind warning (20 meters per second) and even below the construction company’s standards for operational suspension.
Safety Inspections and Precautionary Measures
Despite a safety inspection conducted in June of last year revealing no meaningful issues with the failed turbine, authorities have taken swift action.Yeongdeok-gun has temporarily halted operations of all 23 other generators built around the same time within the complex to prevent similar incidents.
“The priority now is to ensure the safety of the public and prevent further failures,” a senior official stated. “A thorough investigation is underway to determine the root cause of this collapse and assess the structural integrity of the remaining turbines.”
Implications for renewable Energy Infrastructure
This incident highlights the challenges associated with maintaining aging renewable energy infrastructure. While wind power is a crucial component of South Korea’s efforts to diversify its energy sources and reduce carbon emissions, the long-term durability and safety of these installations require ongoing attention.
The failure raises questions about the frequency and thoroughness of inspections for older turbines, as well as the potential need for accelerated replacement or refurbishment programs. A comprehensive assessment of wind turbine lifespans and maintenance protocols across the country may be necessary to mitigate future risks.

This is YTN’s Kim Geun-woo reporting from the Yeongdeok Wind Power Complex.
Why it happened: A 20-year-old wind turbine at the Yeongdeok wind Power Complex collapsed due to a suspected structural issue with a blade, despite passing a safety inspection in June of the previous year. The turbine was operating within acceptable wind speed limits at the time of the failure.
Who was involved: The incident involved the Yeongdeok-gun local authorities, YTN reporter Kim Geun-woo, the construction company responsible for the turbines, and the South Korean government’s renewable energy initiatives.
What occurred: A turbine collapsed, prompting a shutdown of the entire wind farm for safety inspections. No injuries or property damage were reported.
How it ended: Authorities have initiated a thorough investigation to determine the root cause of the collapse and are assessing the structural integrity of the remaining 23 turbines built around the same time. Operations of those turbines have been temporarily suspended as a precautionary measure.
