at the Wind Turbine Test Station, to conirm structural and performance predictions; and
Martha's Vineyard, Massachusetts, to demonstrate the VAWTs applicability to a small
utility system.
The successful operation of the pre-commercial prototypes, including more than 10,000
hours for the Bushland machine, convinced two other manufacturers to further develop the
Sandia/DOE 17-m VAWT into commercial products. The

companies each manufactured VAWTs for use in California wind power stations, with two-
bladed conigurations like that of the turbine shown in Figure 3-24. By the late 1980s, over
600 Darrieus VAWTs were installed in California, with a total rated capacity of over 90
MW.
