CIFI grants USD 30 million in financing to Cox for an energy storage project in Mexico

Panama City, April 21, 2026 – CIFI structured and provided a USD 30 million corporate financing facility to Cox Energy Europa, S.L., a subsidiary of Cox ABG Group S.A. (Cox), an international energy and water infrastructure group, for the development, construction, and commissioning of a battery energy storage system (BESS) in Mexico.

The financing will enable Cox to implement a 90 MW / 270 MWh BESS at the Cuyoaco solar park, located in the state of Puebla. The project is designed to optimize the asset’s operation by shifting solar energy to periods of higher demand, enhance its firm capacity contribution to the Mexican power system, and support greater integration of renewable generation.

The transaction includes participation from CIFI and its Sustainable Infrastructure Debt Fund (SIDF), for up to USD 20 million, and incorporates a combination of corporate and project-level guarantees that evolve as the execution and commissioning of the storage system progress. The financing aligns with energy transition objectives and the growing need for technologies that provide flexibility and stability to power systems.

CIFI’s CEO, César Cañedo-Argüelles, highlighted the strategic value of the transaction: “This financing to Cox reflects CIFI’s focus on supporting energy infrastructure projects with strong technical and financial fundamentals. Energy storage is a key component in advancing more resilient, efficient, and sustainable power systems in Latin America.”

The project represents a meaningful contribution to Mexico’s energy transition by strengthening the integration of renewable generation into the power system through storage solutions. The system is expected to store approximately 84,000 MWh of renewable energy annually, enabling dispatch during peak demand hours and reducing reliance on thermal sources.

María Alejandra Vega, CIFI’s Senior ESG Officer, added: “As a result, the project will help avoid approximately 37,296 tons of CO₂ emissions annually, generating a direct impact on the decarbonization of the power system. Additionally, by improving the reliability and stability of electricity supply, it is estimated that more than 32,800 people will benefit from a safer and more efficient energy service. This type of solution reinforces the role of storage as a key enabler of more resilient, sustainable electricity systems aligned with the region’s energy transition goals.”

With this financing, CIFI strengthens its presence in Mexico’s energy sector, reaffirming its role as a key financial partner in the development of innovative sustainable infrastructure solutions in Latin America and the Caribbean.
