Project Description
If provided by the financial institution, the Early Warning System Team writes a short summary describing the purported development objective of the project and project components. Review the complete project documentation for a detailed description.

According to the IADB, the project aims to support the decarbonization and transformation of Colombia's energy matrix through the generation of renewable energy, contributing to the country's transition toward cleaner and more sustainable sources.

The financing would cover the construction and operation of: (i) the JK1 and JK2 wind farms, with a combined installed capacity of 259 MW; (ii) their internal transmission lines and related civil works, including access roads; and (iii) a substation. The project is being developed by AES Colombia in partnership with Ecopetrol S.A. The wind farms would be connected to the Colombian Electric System via the Colectora 1 Substation, which is part of the UPME 06-2017 Colectora - Cuestecitas - La Loma project.

ACCOUNTABILITY MECHANISM OF IDB / IDB INVEST

The Independent Consultation and Investigation Mechanism (MICI) is the independent complaint mechanism and fact-finding body for people who have been or are likely to be adversely affected by an Inter-American Development Bank (IDB) or Inter-American Investment Corporation (IDB Invest)-funded project. If you submit a complaint to MICI, they may assist you in addressing the problems you raised through a dispute-resolution process with those implementing the project and/or through an investigation to assess whether the IDB or IDB Invest is following its own policies for preventing or mitigating harm to people or the environment. You can submit a complaint by sending an email to MICI@iadb.org. You can learn more about the MICI and how to file a complaint at http://www.iadb.org/en/mici/mici,1752.html (in English) or http://www.iadb.org/es/mici/mici,1752.html (Spanish).
