Iberdrola Sells Mexico Energy Business to Cox in $4B Deal
Spanish infrastructure and energy company Cox has completed the acquisition of Iberdrola’s Mexico business in a deal valued at approximately $4 billion USD, marking a significant consolidation in Latin America’s power sector.
Cox is a growing utility and infrastructure group focused on energy generation, water management, and grid-linked assets, while Iberdrola is one of the world’s largest utilities, operating across renewable energy generation and regulated electricity networks in multiple regions.
The transaction includes around 2.6 GW of installed generation capacity, consisting of natural gas, wind, and solar assets, as well as a large pipeline of future renewable projects and commercial electricity supply operations. The portfolio also serves more than 500 industrial and commercial customers across Mexico.
The deal was valued at approximately $4.2 billion USD, including debt financing, and represents one of the largest recent energy infrastructure transactions in Latin America.
For Iberdrola, the sale is part of a broader strategy to focus on regulated electricity networks and core markets such as Europe and the United States, where it continues to invest heavily in transmission and distribution infrastructure.
For Cox, the acquisition significantly expands its presence in Mexico, positioning the company as a major integrated utility player in the region. The company has also outlined plans for further investment in energy generation and infrastructure development, including grid-connected assets.
While the portfolio includes generation assets, the transaction also has broader implications for grid infrastructure and substations, which are essential for integrating the acquired capacity into Mexico’s transmission system. The assets rely on interconnection points, substations, and transmission corridors to deliver electricity to industrial customers and regional distribution networks. As a result, the deal reinforces the importance of grid infrastructure alongside generation capacity in enabling energy system expansion.
The acquisition includes both operational assets and a pipeline of future projects, giving Cox exposure to long-term growth in renewable energy and flexible generation markets. With this acquisition, Cox strengthens its position in the Latin American energy market, while Iberdrola continues its transition toward grid-focused investments in major global markets. The transaction highlights ongoing consolidation in the energy sector, where generation assets, substations, and transmission infrastructure are increasingly being managed as part of integrated utility platforms rather than standalone systems.
