Blades from two early generation AWP 56/100 turbines in Tarifa fell off last month, sparking fears among neighbours about the safety of wind farms. The AWP 56/100s were built by a now defunct joint venture made up of Spanish conglomerate, Abengoa, and Kenetech, then called US Windpower. Tomas Andueza, managing director of an Abengoa wind subsidiary, Desarrollos Eolicos, told reporters it was too early to judge what had caused the failure. In the US, Kenetech officials say the accident was unusual, but since they no longer maintain the machines will not speculate on the cause. Kenetech is adamant, however, that there is no danger of blades coming off its new KVS-33 machines going up in Tarifa. The AWP machines are comfortably stationed inland, but, to the consternation of locals, the 30 MW of KVS-33 units will overlook a main road.
