In Turco, the 13 beneficiaries of the project are grouped in five villages: Iruni, Villacollo Norte, Villacollo Sur, Huasquiri and Huasquiri Collo with 5, 3, 2, 2 and 1 households, respectively. In Challapata the 9 beneficiaries are dispersed and only two of them are close to each other. Given the dispersion of the households, the project promoters decided to install one individual wind turbine at each household. The chosen were the AIR-X-South West Windpower, which were distributed by SIE, a Bolivian company which offers the distribution, installation and maintenance service.

The design of wind systems at each household was carried out taking into account that turbines operate at a rated voltage of 12 V direct current-CC, and includes the generation system, regulation (directly incorporated into the wind turbine) and energy storage. The home system components are as follows:

From the different technological options and according to the result of the wind resource evaluation, the promoters of the project decided to use wind energy to electrify these

In 2009, 22 wind turbines were installed, 13 in the municipality of Turco and 9 in Challapata; in total, 80 people were beneficed. To ensure proper operation and maintenance of systems throughout the year, only households with permanent residents throughout the year were
