Abstract--Wind energy is quickly becoming a major player
among today’s electricity producers. Due to increasing
environmental awareness and to have sustainable system, Algeria
is also looking forward to using the wind power to generate
electricity. There is an Algerian and German cooperation
concerning the CO2 emission purchase planned by the Kyoto
protocol. The Algerian Government has been promoting the use
of renewable energy (wind energy, solar, biomass, geothermal,
etc.) by means of a series of laws and official programmes. This
paper utilized wind speed data over a period of almost 10 years
between 1977 and 1988 from three stations, namely Adrar,
Timimoun and Tindouf. The analyses include the variation of
seasonal and diurnal wind speed values. The annual energy
output and capacity factors were also estimated for WECSs of
different sizes between 150 and 1300 kW. It was noticed that
Adrar is the best location among the sites considered, for
harnessing the wind power, while Timimoun is the second best
location and Tindouf is placed at number three.
