Wind Farm Vader Piet Aruba
In February 2008 the Water and Electricity Company Aruba ("WEB") requested for proposals to "build, own and operate" wind farm Vader Piet and to supply all related electricity to WEB. The Vader Piet wind farm consists of 10 turbines of the Vestas V90 type with a hub height of 105 metres and a rotor diameter of 90 metres . The foundations consist of circular concrete bases with a diameter of 13 metres, which are anchored in the limestone rock. The 24 GEWI anchors have a steel diameter of 63 mm and are drilled into the rock to a depth of 10 metres (drill diameters of 200 mm). Several test anchors were installed to examine the behaviour and bearing capacity of this rock. Due to its high capacity, it was possible to strongly reduce the size of the foundation bases. The sub soil was also subjected to plate bearing tests. Based on the test results, an inspection programme was performed. In total, the Vader Piet wind farm produces 20% of Aruba’s total electricity needs.The rated power per turbine is 3 MW and the rated total power is 3 MW. The turbines have been provided by Vestas. Further details are mentioned below.
