Blade detaches from turbine at Future Generation Wind, Plymouth, Massachusetts

What happened

In November 2025, in the early afternoon, a blade detached from a turbine at Future Generation Wind, a small onshore wind farm in the Buzzards Bay area of Plymouth, Massachusetts, United States, operated by RWE. Reports described the turbine as around 90 metres to blade tip and the detached section as roughly 23 to 30 metres long. The blade came to rest several hundred feet from the tower base on low-lying agricultural land.

A member of the public first reported the event after noticing that one of the three blades was missing. The local fire service attended and found no hazards in the immediate aftermath. There were no injuries and no occupied buildings were struck. The site comprises four turbines of about 2 MW each, commissioned in 2016, with maintenance carried out by the turbine manufacturer under contract. Following the event RWE shut down all four turbines at the site as a precaution and began a root cause analysis with the manufacturer.

The state environmental regulator and the local building inspector were notified and carried out their own reviews. The local authority stated publicly that oversight of turbine safety rests with the permit holder and property owner rather than with the town. The fallen blade was visible from a nearby highway and the event attracted considerable local attention.

Contributing factors

No cause had been published at the time of reporting. RWE and the turbine manufacturer stated that a root cause analysis had been started and that the investigation would be conducted jointly. A neighbour was reported in the media as having heard a squealing noise from the turbine in the period before the failure, which had reportedly stopped shortly beforehand. This is an unverified public observation and had not been linked to the failure by any published investigation. Regulators and the local inspector were notified but no findings were in the public domain.

Lessons learned

1. Shut down sister turbines of the same type and service history at a site after an unexplained blade failure until the root cause is understood.
2. Treat blade release as a credible event when assessing land use around each turbine and record throw distance assumptions.
3. Log and investigate third party noise reports as potential condition data for changes in noise or vibration.
