Two existing wind farms in Curacao at Tera Korá, 12 turbines installed in 1992, and Playa Kanoa, 18 turbines installed in 1999, were replaced by 10 turbines of the 3 MW class. On behalf of NuCapital, ABT was involved as engineers and for the foundation design. The new wind turbines have a hub height of 80 metres and a rotor diameter of 90 metres. The project was executed in a very short period between May 2010 and December 2010, almost 5 months shorter than usual.
