Siemens Gamesa turbine collapses at Arizona wind farm in Brazil

On Sunday 30 January 2022 a Siemens Gamesa wind turbine collapsed at the 49.3MW Arizona onshore wind project in Rio do Fogo, Rio Grande do Norte, Brazil. The collapse included the turbine's third section. Siemens Gamesa said the customer was notified immediately and that no injuries were incurred. A safety zone was established around the collapsed turbine and the manufacturer launched a full investigation to determine the root cause. No further details on the cause, extent of damage to surrounding infrastructure, or repair timeline were disclosed at the time of reporting.

Not reported. The root cause was under investigation at the time of the report.

1. Structural failures can occur without warning even in operating turbines, underlining the need for regular structural integrity inspections.
2. Establishing an immediate safety exclusion zone around a failed turbine helps protect personnel and the public while investigations proceed.
3. Prompt manufacturer notification and transparent public disclosure of collapse incidents, even without injuries, support broader industry learning on turbine reliability.
