Acciona Agrees to Sell US, Mexican Solar and Wind Portfolio

Acciona Energía agreed to sell its portfolio of solar and wind power assets in the United States and Mexico to the investment firm Mexico Infrastructure Partners (MIP) for US$1 billion, the company announced. The transaction marks a strategic shift for the Spanish renewable energy developer and signals continued foreign investment activity in North America’s clean energy markets.

Under the agreement, Acciona Energía will sell a 49% stake in a 1.3GW photovoltaic portfolio in the United States while retaining a 51% controlling interest. The company will continue to operate and maintain the solar assets following the transaction, preserving its role as the long-term operator.

The US solar portfolio included in the deal consists of four plants located across key power markets. These assets are the Red-Tailed Hawk solar plant with 458MW peak and the Fort Bend Solar facility with 316MW peak, both in Texas, the High Point Solar Farm with 127MW peak in Illinois, and the Union Solar project with 415MW peak in Ohio. Together, the assets represent a geographically diversified portfolio with operational scale in regions with sustained demand for utility-scale renewable generation.

In Mexico, Acciona Energía agreed to sell 100% of two wind parks with a combined installed capacity of 321MW. The assets include the El Cortijo wind farm with 183MW and the Santa Cruz wind farm with 138MW, both located in the municipality of Reynosa, in the northern border state of Tamaulipas. The projects are part of the wind corridor in northeastern Mexico, a region with established transmission links and proximity to industrial demand.

Acciona Energía said the transaction is expected to close in 1H26, subject to customary regulatory approvals, fulfillment of conditions related to the transaction perimeter and completion of financing by the buyer.

Acciona Energía said the sale reflects its intent to optimize its asset base and focus on selective markets and technologies in line with its broader strategic plan. The company has been active in restructuring its international holdings to streamline operations and bolster financial flexibility, particularly in response to evolving energy policies and investment conditions across North America and Europe.

The buyer, MIP, is an investment firm focused on energy and infrastructure opportunities in Latin America and North America. MIP has previously participated in renewable energy transactions and aims to expand its footprint in the solar and wind sectors by acquiring operational assets with stable cash flows as well as development pipelines. In statements accompanying the announcement, MIP described the acquisition as an opportunity to deepen its presence in renewable generation and support the energy transition goals of local markets.
