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 IDBI, the project aims to expand the Yacyreta hydropower by increasing renewable generation capacity and optimizing existing water flows to strengthen energy supply in Argentina and Paraguay, while avoiding the need for a new reservoir. Its scope includes the construction of a new plant at the Ana Cua branch with 270 MW of installed capacity, along with associated civil works, transmission infrastructure, substations, interconnection systems, and environmental and social management measures.

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).
