Iberdrola Reaches Over 11 GW of Installed Capacity in US

Why It Matters

The capacity expansion positions Avangrid as a key supplier for the surging power needs of AI‑driven data centers and broader electrification, while bolstering Iberdrola’s growth in its most lucrative overseas market.

Key Takeaways

• Avangrid now exceeds 11 GW capacity across 25 states
• U.S. generation hit 25,058 GWh, second only to Spain
• $61 million local taxes paid by on‑shore projects in 2025
• U.S. assets represent $15.6 billion of Iberdrola’s portfolio
• Investment plan allocates €16 bn (~$17.5 bn) to U.S. by 2028

Pulse Analysis

Avangrid’s recent milestone of surpassing 11 GW of installed capacity underscores the rapid scaling of renewable assets in the United States. The portfolio, spread across wind, solar, cogeneration and a modest offshore wind presence, delivered 25,058 GWh in 2025—enough to power roughly 2.3 million homes. This output places the U.S. as Iberdrola’s second‑largest generation market, trailing only its home country Spain, and reflects a diversified mix where on‑shore wind alone contributed over 19,000 GWh. The breadth of projects across 25 states also mitigates geographic risk and aligns with the company’s goal of reaching 85 % emission‑free generation by 2028.

The surge in capacity is directly linked to the growing electricity demand from data centers that fuel the nation’s AI revolution. Avangrid’s statement highlights that its assets help meet this demand while supporting on‑shore manufacturing and broader electrification initiatives. Beyond power, the company’s on‑shore projects generated $61 million in local tax revenue in 2025, reinforcing their role as economic engines for communities. This fiscal contribution supports public services such as education and safety, illustrating how renewable expansion can deliver both environmental and socioeconomic benefits.

Looking ahead, Iberdrola’s €58 billion ($63 billion) investment roadmap dedicates €16 billion ($17.5 billion) to U.S. network upgrades and regulated asset growth through 2028. The capital infusion aims to modernize transmission, accommodate higher renewable penetration, and lock in higher regulated rates that have already boosted Iberdrola’s U.S. revenue by 15 % year‑over‑year. For investors and policymakers, Avangrid’s trajectory signals a robust, profit‑driven pathway for renewable integration in a market increasingly defined by data‑intensive workloads and aggressive decarbonization targets.
