Iberdrola Sets New Record in Distributed Energy with Over 124,000 GWh in H1 2025, Strengthens Global Clean Energy Leadership
Iberdrola, one of the world’s largest energy companies and a global leader in renewable electricity, has surpassed a major operational milestone in the first half of 2025. The company distributed more than 124,201 gigawatt-hours (GWh) of electricity globally during this period, marking a 4.8% increase compared to the same timeframe in 2024, according to a filing submitted to Spain’s National Securities Market Commission (CNMV).
This record-breaking figure reflects the company’s strategic focus on modernizing its electricity networks and expanding its generation capacity, particularly in clean energy. The surge in distributed energy is part of Iberdrola’s long-term commitment to the energy transition, digital transformation, and the decarbonization of the global electricity supply.
Strong Growth Across Core Markets
The growth in distributed energy during the first half of 2025 has been most pronounced in the United Kingdom, where volumes exceeded 20,000 GWh, representing a remarkable year-on-year increase of over 30%. This surge was largely driven by Iberdrola’s recent acquisition and integration of Electricity North West (ENW), one of the UK’s major distribution network operators. The addition of ENW has significantly expanded Iberdrola’s footprint in the British energy market, reinforcing its role in supporting the UK’s net-zero strategy.
Meanwhile, in Spain, Iberdrola’s home market, electricity distribution also experienced positive growth, increasing by 2.5% to 44,871 GWh. This consistent domestic performance underscores the company’s robust operational foundations and its ability to maintain a stable and secure supply of electricity to millions of households and businesses.
Enhancing Security of Supply through Local Generation
In tandem with its achievements in electricity distribution, Iberdrola also reported a rise in its own electricity generation, which reached 66,300 GWh during the first six months of 2025. This figure represents a 2.3% increase compared to the same period in 2024 and reflects ongoing investments in expanding and diversifying its energy portfolio.
By geography, several regions stood out for their generation growth:
- Iberdrola Energía Internacional reported a 15.7% increase in electricity generation. This growth was especially fueled by the rapid expansion of offshore wind projects in France and Germany, which saw a 68% increase in output.
- In Brazil, the company achieved an 11.7% increase in generation, thanks to more favorable hydrological conditions that boosted hydroelectric output, a key part of the country’s clean energy mix.
- Spain also registered a 6.4% increase in generation, supported by gains across a mix of technologies including solar photovoltaic, nuclear energy, and combined-cycle gas turbines.
Offshore Wind and Solar Energy Drive Technology Growth
From a technology perspective, Iberdrola’s second-quarter performance highlighted strong momentum in offshore wind and solar power. Offshore wind output rose by 42% in Q2 2025 compared to Q2 2024, reflecting the commissioning and ramp-up of several large-scale marine wind farms in European waters.
Meanwhile, solar power—which is increasingly becoming a strategic pillar of Iberdrola’s generation mix—registered a staggering 57.4% growth in the second quarter alone. This dramatic increase underscores the scalability and cost competitiveness of solar PV technology, as well as Iberdrola’s aggressive push into sunny markets across southern Europe, Latin America, and the U.S. Southwest.
Renewable Capacity Reaches New Heights
As a result of sustained capital deployment and a clear focus on the energy transition, Iberdrola’s installed capacity has now climbed to 57,273 megawatts (MW) globally, following the addition of 1,800 MW in newly commissioned assets in the first half of 2025.
Most significantly, renewable energy now makes up over 45,000 MW of Iberdrola’s total capacity. This marks the first time in the company’s history that renewables have crossed the 45 GW threshold, representing approximately 79% of its total installed capacity.
This milestone underscores Iberdrola’s role as a world leader in clean electricity and places the company at the forefront of global decarbonization efforts. It also reflects the successful execution of its capital investment strategy, which aims to expand its renewable base across key markets including the U.S., the UK, Spain, Brazil, and Australia.
Low-Carbon Leadership and Global Emissions Performance
One of the hallmarks of Iberdrola’s strategy is its steadfast commitment to emissions reduction. The company continues to enhance energy security and sustainability by generating nearly all its electricity from low- or zero-emission sources.
In Spain, a country where energy security and decarbonization go hand-in-hand, 91% of Iberdrola’s generation is now emission-free. This is in line with national and EU targets for climate neutrality and energy independence.
Moreover, the company has achieved 100% emissions-free generation in several other key countries, including:
- United Kingdom
- United States
- Brazil
- France
- Germany
- Italy
- Poland
- Portugal
- Greece
- Australia
This broad decarbonization footprint speaks to Iberdrola’s operational excellence, as well as its ability to align with and support climate policy objectives in a wide range of jurisdictions.
Decades of Investment in the Energy Transition
The remarkable performance reported for the first half of 2025 builds upon Iberdrola’s long-term investment approach. Over the past 25 years, the company has invested approximately €175 billion to expand and modernize its electricity grids, build world-class renewable energy infrastructure, and drive the digital transformation of the electricity sector.
These investments have been guided by a clear strategic vision: to create a safer, more efficient, cleaner, and more competitive energy system. Iberdrola’s capital allocation has consistently focused on future-oriented technologies and markets, ensuring the company remains resilient and adaptive in a rapidly changing energy landscape.
Supporting a Global Energy Transformation
Through its dual focus on expanding electricity distribution and clean generation, Iberdrola is playing a pivotal role in the global transition to net-zero. The company is not only delivering results in terms of scale and output but is also actively reshaping how electricity is produced, delivered, and consumed.
As more countries prioritize decentralized generation, grid resilience, and energy independence, Iberdrola’s model—anchored in renewables and smart grids—offers a proven pathway forward. Its achievements in the first half of 2025 serve as a strong testament to the power of long-term vision, sustainable investment, and technological innovation in transforming the global energy sector.
