A Suzlon 2.1MW turbine nacelle caught fire and later crashed to the ground on Sunday in an incident involving three damaged turbines at the 63MW Amayo complex in Nicaragua, the country’s first wind project.
“There were no injuries and the site has been secured,” Suzlon told Windpower Monthly in a written statement, confirming the affected turbines to be S88-2.1MW machines.
Suzlon declined to comment on the possible cause, pending further investigation. Nobody at the US-based owner company, AEI Energy, was available for comment.
Local press reports, citing ground staff and fire fighters, said all three machines at the 23MW Amayo II plant – in service since 2010 – suffered failure in their emergency braking systems, leaving them helpless against high gusts of wind. No other turbines were affected, claimed Suzlon.
The turbines caught ablaze at 5.15am, just under an hour after a blackout hit the Rivas municipality, where the wind farm is located.
All three machines reportedly spun uncontrollably. Turbine 28 finally fell and all three blades of turbine 25 were flung off. A blade on turbine 29 was left broken.
