Avangrid Inc., the U.S. subsidiary of Spanish power and gas utility Iberdrola SA, recently announced that its installed capacity in the United States has surpassed 11 gigawatts (GW) through nearly 100 projects spanning 25 states.

“Avangrid’s expanding portfolio is helping to meet the surging energy demand across the United States, driven by the booming data center sector supporting the nation’s AI revolution, as well as by the growth of emerging domestic manufacturing and ongoing electrification efforts.” Avangrid stated in an online release, “The company maintains a diverse pipeline of power-generation projects to support future nationwide growth.”

Avangrid pointed out that while these projects can reliably and safely supply electricity to households, businesses, and industry, they also serve as significant economic drivers. In 2025, Avangrid’s onshore projects paid a total of US$61 million in local taxes, supporting public services such as education and public safety.

According to Iberdrola’s earnings report released on February 25, 2026, Avangrid generated 25.058 billion kilowatt-hours (25,058 GWh) of electricity last year. These figures make the United States Iberdrola’s second-largest country in terms of net electricity generation, behind Spain (64.678 billion kWh) and ahead of Mexico (11.667 billion kWh), Brazil (10.936 billion kWh), and the United Kingdom (7.368 billion kWh).

The report shows that by 2025, the net electricity generation mix in the United States will be as follows: onshore wind power at 19.123 billion kWh, combined heat and power at 3.149 billion kWh, solar power at 2.354 billion kWh, offshore wind power at 308 million kWh, hydropower at 45 million kWh, and natural-gas combined-cycle power at 11 million kWh. As of the end of 2025, the United States accounts for US$15.6 billion of Iberdrola’s asset base.

In 2025, Iberdrola reported a net profit of €6.29 billion (approximately $7.23 billion), with adjusted net profit at €6.23 billion. These figures represent increases of 12% and 10%, respectively, compared with 2024. The network business segment, which encompasses electricity and natural gas transmission and distribution, reported revenue of €20.92 billion in 2025, an 11% year-on-year increase. Among them, the U.S. region contributed €7.16 billion, representing a 15% increase.

Iberdrola attributed its overall revenue growth to “an increase in the regulated asset base, the consolidation of ENW (UK) effective March, higher electricity prices in the United States and Brazil, and a greater contribution from the Iberian region.” In the Power & Customer Services business segment, which encompasses retail electricity and natural gas operations, revenue in 2025 amounted to €24.89 billion, a year-on-year decrease of 5.3%. Except for the United States, electricity and customer service revenue declined in all other countries.

“As of the end of 2025, Iberdrola’s total installed capacity will have increased by 3% compared with 2024, exceeding 58.3 gigawatts, with zero-emission sources accounting for 85% (493.38 terawatt-hours),” the report stated. The United States is set to receive €16 billion under a €58 billion investment plan extending to 2028, which focuses on expanding regulated networks. The company announced the plan on September 24, 2025.
