The wind deposit map in Algeria

Annual winds map ( m/s ) in 10m of the ground estimated by Dr Boudia [1]

The Renewable Energies Development Center (CDER), published, on the occasion of the winter solstice, a new map of the national wind deposit.

Beeing envolved in a new exploitation phase of renewable energies, Algeria expects to reach by 2030 about 40 % of the national electricity production from renewable sources. Although the choice of solar energy is predominant, the wind energy remains the second choice in this program. Before studying the possiblity of implanting a wind farm in a given region, it is necessar to study the wind deposit for an accurate knowledge of the wind behavior.

In this way, many researchers from the EPST CDER have since few years directed their researches on the development of Algerian winds maps.

The latest study is made in 2013 by Dr. Sidi Mohammed Boudia who realized a winds map from 10m [1], by using the newest meteorological data and a bigger measurment points by reference to previous works.

Another study on the Algerian wind deposit was realized by Dr. Farouk Chellali in 2011 [2-3]. This last one brought a spectral analyze to study the wind cyclic phenomenaand contributed to update the wind map of Algeria by introducing Hassi-R’Mel which was underestimated in the precendent works. Recall that Dr. Farouk Chellali was a prize-winner of the second price of the DESERTEC Thesis Award for the MENA region by studying the stochastic and cyclic behavior of the wind in Algeria.

One of the first works of wind map over the country at 10 m high was realized in 2006 by Nachida Kasbadji Merzouk [4].

The elaboration of the whole Atlas wind by researchers of the EPST CDER, was made by statistical analyses by using distributions, to adjust collected data with the National office of Meteorology ( ONM). Although the number of test points distributed on the whole national territory is relatively low compared with the large surface of the country, the wind maps established by the researchers of the CDER doubtless remain a reference basis for the various actors of the socioeconomic sector who plan the development of this energy in the country.
