Wind statistics for Greece show that the conditions prevailing on the Aegean islands--i.e. considerable amounts of wind energy, small electrical loads and high generation costs--are especially favorable for the installation of wind turbine generators (WTGs). This study gives preliminary design parameters for WTGs at six locations and evaluates their performance. The duration of operation varies from 5000 to 7400 hours annually and the specific production is between 2300 and 3600 kwh/kw. The installation of the WTGs would result in diesel fuel savings corresponding to a month's consumption. Finally, the cost of wind generated electricity will be lower than that from diesel engines one to three years after the installation of the WTGs.
