The Olmos Transverse Irrigation Project, a major infrastructure initiative in Peru, exemplifies complex project finance structures in emerging markets. Officially named the Olmos Tinajones Irrigation Project, its primary goal is to divert water from the Huancabamba River, located on the eastern side of the Andes Mountains, through a trans-Andean tunnel to irrigate the arid Olmos Valley on the Pacific coast.
The project was structured as a Public-Private Partnership (PPP), a common approach for large-scale infrastructure developments in regions with limited public funding. This model allowed the Peruvian government to leverage private sector expertise and capital, sharing both the risks and rewards associated with the project. The concession was awarded to Concesionaria Trasvase Olmos S.A., a special purpose vehicle (SPV) established by Odebrecht Latinvest, a Brazilian conglomerate, specifically for this project. Following Odebrecht’s challenges stemming from corruption allegations, the concession was acquired by Brookfield Infrastructure Partners.
The financing of the Olmos project was a multi-layered affair, involving a combination of debt and equity. Debt financing was secured from a consortium of international and local banks, including development finance institutions (DFIs) like the Inter-American Development Bank (IDB) and Corporación Andina de Fomento (CAF). These institutions played a crucial role by providing long-term loans at relatively favorable interest rates, which is often crucial for the viability of large infrastructure projects. They also imposed stringent environmental and social safeguards, ensuring that the project adhered to international best practices.
The project was divided into two main stages: the transfer of water (transvase) and the irrigation of the Olmos Valley. The transvase component involved the construction of the trans-Andean tunnel and the dam. The irrigation component focused on building the necessary irrigation infrastructure within the Olmos Valley to distribute the diverted water. Each component had distinct financing requirements and risk profiles.
One of the key challenges in project finance for Olmos, and projects like it, is managing the various risks inherent in such complex undertakings. Construction risk, particularly related to tunneling through the Andes, was a significant concern. Delays, cost overruns, and geological uncertainties all posed potential threats to the project’s financial viability. Market risk, related to the demand for irrigated land and the prices of agricultural products, also played a crucial role. Furthermore, political and regulatory risks, common in emerging markets, required careful consideration and mitigation strategies.
The successful completion of the Olmos project is expected to significantly boost agricultural production in the Olmos Valley, creating new jobs and economic opportunities for the local population. It also serves as a potential model for other large-scale irrigation projects in arid regions, demonstrating the potential of PPPs to address critical infrastructure needs. However, the controversies surrounding Odebrecht highlight the importance of robust governance and transparency mechanisms in ensuring the long-term sustainability and ethical conduct of infrastructure projects.
