Cox Infrastructure Group, S.A. is a multinational utility and infrastructure corporation operating across the water and energy sectors. Founded in 2014 by Enrique Riquelme as Cox Energy Solar, the group transformed its scope and technical capabilities in 2023 by acquiring the core productive business units of Abengoa out of insolvency proceedings, and further broadened its scale through the acquisition of Iberdrola México in 2025–2026.
The company operates through a dual-structure framework consisting of AssetCo, which owns and manages long-term concession assets that deliver recurring, regulated or contract-backed cash flows, and ServiceCo, which provides turnkey engineering, procurement, and construction (EPC) and operation and maintenance (O&M) services. The business is structured into four main operating segments: Water, Energy, Services, and Corporate. The Water division develops and operates large-scale reverse osmosis desalination plants (including landmark facilities such as Taweelah in the UAE, Jubail 3A and Rabigh 3 in Saudi Arabia, and Agadir in Morocco), water treatment, and municipal supply concessions. The Energy division owns and operates solar photovoltaic complexes, concentrated solar power (CSP) assets such as the Khi Solar One plant in South Africa, bioenergy facilities such as the São João plant in Brazil, combined-cycle power plants, and high-voltage transmission lines. A key strategic model is 'Energy Follows Water', leveraging synergies between power supply and water infrastructure concessions.
Geographically, Cox operates across key markets in Mexico, Brazil, Chile, Central America (Guatemala and Panama), Spain, Morocco, Algeria, South Africa, Saudi Arabia, and the United Arab Emirates.
