Relevance of the Closure

With this resolution, a key stage of the environmental processing of the Cuatro Vientos Wind Farm is closed, a wind generation project by Colbún S.A. in the Los Lagos Region. The closure of the PCPI, carried out under the standards of ILO Convention No. 169, clears an essential procedural requirement for the EIA to continue its evaluation, in a context where respect for the rights of indigenous peoples is a condition for the advancement of renewable energy projects in the country.
