The electricity distributed by Iberdrola exceeded 124,201 GWh in the first half of 2025, representing an increase of 4.8% compared to the same period of the previous year, as reported to the Spanish National Securities Market Commission (CNMV).
The growth has been particularly notable in the United Kingdom, where distributed energy has increased by more than 30%, exceeding 20,000 GWh, thanks to the integration of the British distributor ENW. In Spain, distributed electricity increased by 2.5% to 44,871 GWh in the first half of the year.
More local generation to provide security of supply and energy autonomy
Likewise, Iberdrola's own generation has reached 66,300 GWh during the first six months of the year, 2.3% more than in the same period of the previous year. By country, the production increases at Iberdrola Energía Internacional (+15.7%) stand out, thanks to the 68% growth in offshore wind farms in France and Germany; in Brazil (+11.7%), driven by higher hydroelectric production; and in Spain (+6.4%), with growth in both renewable technologies (especially solar) and nuclear and combined cycles.

This growth in generation has been possible thanks to investments in new capacity, which reaches 57,273 MW after having commissioned 1,800 MW. In particular, the Group's renewable capacity has exceeded 45,000 MW worldwide for the first time – specifically it has closed at 45,082 MW – with a growth of around 4%, and now accounts for 79% of the Group's total capacity.
In this way, Iberdrola continues to promote energy self-sufficiency and security in all the countries where it operates, generating 91% of its production in Spain without emissions and 100% in countries such as the United Kingdom, the United States, Australia, Brazil, France, Italy, Germany, Poland, Portugal and Greece.
Commitment to the transformation of the sector
These data confirm Iberdrola's growth path in both electricity networks and renewable generation thanks to the investments made, which reach 175 billion euros in the last twenty-five years. With this, Iberdrola promotes a safer, more efficient, cleaner and more competitive energy system in all the countries in which it operates.
