The Gamma 60 wind turbine, a 1.5 MW two-bladed upwind horizontal axis wind turbine, was installed by Wind Energy Systems Taranto S.p.A. (WEST) at Alta Nurra, Sardinia, Italy in April 1992.[1] Founded on original research and development work by NASA and Hamilton Standard (then a division of United Technologies Corporation), the Gamma 60 wind turbine was the world's first variable speed wind turbine with a teetering hinge.[2][3]
The Gamma 60 wind turbine was commissioned to assess the feasibility and performance of power regulation through yaw control, rather than industry-standard blade pitch control, including broad range variable speed in a two-bladed teetering hinge wind turbine.[4]
The WEST Gamma 60 wind turbine project team included Hamilton Standard, ENEL, Aeritalia, Finmeccanica (now Leonardo), ENEA (Italy), and Sulzer.[5]
Three Gamma turbines were manufactured, and one was erected and successfully tested from 1992 - 1997 on the Mediterranean island of Sardinia.[2][5] Commercialization of the Gamma 60 prototype was planned, including a conditional investment for 10 Gamma turbines by a US utility, but legal disputes and contractual claims between WEST and ENEL, the privatization of ENEL, and tumbling oil prices in 1998 resulted in the program's cancellation.[4][6][7][8][9]
