Iberdrola’s Global Electricity Distribution Rises 6% to 188,753 GWh, Driven by Strong Growth in the UK and Spain
Iberdrola, one of the world’s leading energy companies and a major driver of the global energy transition, reported a significant increase in its electricity distribution and production figures for the first nine months of 2025. According to its filing with the National Securities Market Commission (CNMV), the company distributed a total of 188,753 gigawatt-hours (GWh) of electricity worldwide between January and September 2025, marking a 6% year-over-year increase. This growth was primarily powered by robust performance in the United Kingdom, where distribution surged by 43% following the integration of Electricity North West, and a 3% increase in Spain, supported by rising demand and continued electrification trends.
Strong Global Momentum Driven by Electrification and Demand Growth
The company’s strong distribution figures reflect the growing global momentum behind electrification and renewable integration. Iberdrola has been strategically expanding its distribution networks and investing heavily in modernization and digitalization to handle increasing power demand in both advanced and emerging markets.
The rise in distributed electricity coincides with a parallel increase in the company’s global power generation, which reached 96,047 GWh during the first three quarters of 2025. Iberdrola’s generation growth underscores both the resilience of its diversified portfolio and the effectiveness of its investments in clean energy infrastructure.
Across its global footprint, Iberdrola Energía Internacional reported a 15% increase in generation, driven by new renewable projects coming online and enhanced operational performance. In Spain, generation rose 5%, reflecting stable domestic demand and improved hydrological conditions. Brazil also delivered solid growth of 3%, supported by the expansion of renewable assets and favorable market conditions.
A particularly noteworthy development occurred in the United Kingdom, where production expanded by 9% in the third quarter alone, signaling a strong recovery driven by both favorable wind resources and the contribution of new renewable projects.
Renewable Energy Leadership: Offshore and Solar Power Drive Growth
By technology, Iberdrola’s generation mix continues to shift decisively toward clean energy sources, demonstrating the company’s commitment to sustainability and decarbonization. The offshore wind segment registered a 33% year-over-year increase in output, reflecting major contributions from operational projects across the United Kingdom, Germany, France, and the United States. These projects form part of Iberdrola’s broader effort to consolidate its leadership position in offshore wind, an area in which it already ranks among the world’s top operators.
The solar energy portfolio also delivered remarkable growth, with generation soaring 41% during the period. This growth was led by high-performance plants in Spain, the United Kingdom, and the United States, along with expanding capacity in Portugal and Italy. The company’s continuous investment in large-scale solar parks across Europe and the Americas has been central to achieving its goal of increasing renewable generation capacity and reducing emissions intensity.
These trends highlight Iberdrola’s balanced and diversified renewable mix, which integrates wind, solar, hydroelectric, and battery storage assets to ensure stability, flexibility, and reliability across its global networks.
Expanding Installed Capacity: Renewables at the Core
As of September 30, 2025, Iberdrola’s total installed capacity reached 57,453 megawatts (MW) worldwide, further strengthening its position as one of the largest clean energy producers globally. Of this total, more than 40% corresponds to onshore and offshore wind power, demonstrating the company’s long-term commitment to harnessing one of the most mature and scalable renewable technologies.
Another 22% of installed capacity comes from hydroelectric power, which remains an important component of Iberdrola’s generation portfolio. Hydropower continues to play a key role in balancing intermittent renewable sources, supporting energy storage, and maintaining grid stability. Meanwhile, solar energy accounts for 15% of total capacity, with the company rapidly expanding solar installations in multiple regions.
A particularly noteworthy achievement is the growth of Iberdrola’s battery energy storage capacity, which has reached 503 MW, representing an impressive 154% increase compared to the previous year. New battery projects in Australia, Spain, and the United Kingdom have strengthened the company’s ability to store renewable energy, manage grid fluctuations, and enhance system resilience—capabilities that are increasingly vital as renewable penetration continues to grow.
Geographic Expansion and Strategic Investments
Iberdrola’s generation and distribution assets are strategically diversified across multiple continents. The company has made substantial progress in increasing its installed capacity across nearly all major markets:
- Spain remains the cornerstone of Iberdrola’s global operations, with 32,125 MW of installed capacity. The country continues to benefit from a strong pipeline of onshore wind and solar projects supported by government incentives for renewable development.
- In the United Kingdom, installed capacity now stands at 3,158 MW, reflecting ongoing investments in offshore wind farms and the integration of Electricity North West’s network assets.
- The United States contributes 10,581 MW of installed capacity, driven by both onshore wind and large-scale solar projects, as well as the expansion of grid modernization initiatives under Avangrid, Iberdrola’s U.S. subsidiary.
- Brazil adds 4,167 MW, supported by the company’s robust renewable portfolio and continued development in hydroelectric and onshore wind resources.
- In other international markets—including Australia, Germany, Italy, and Portugal—Iberdrola collectively manages 4,823 MW, underlining the growing importance of its diversified international presence.
This widespread geographic footprint allows Iberdrola to mitigate regional risks while capitalizing on localized policy support for renewables and energy transition initiatives.
Sustainability at the Core: Lower Emissions and Cleaner Production
Iberdrola continues to make impressive progress in reducing its carbon intensity. The company reported that its specific emissions fell to 57 grams of CO₂ per kilowatt-hour generated during the first nine months of 2025, down from 63 grams in the same period of 2024. This significant reduction highlights the impact of sustained investments in renewable energy and the gradual phasing out of fossil-based generation.
Currently, 86% of Iberdrola’s total electricity production and 84% of its installed capacity come from clean, renewable sources. This figure places Iberdrola among the lowest emitters in the global energy sector and reinforces its role as a pioneer in decarbonized power generation.
