Iberdrola increased global electricity distribution by 6% to 188,753 GWh in the first nine months of 2025, driven by strong growth in the UK (+43%, including Electricity North West) and Spain (+3%), according to its report to the CNMV.

In the third quarter alone, UK generation rose 9%. Offshore wind output grew 33%, led by projects in the UK, Germany, France, and the US, while solar generation rose 41%, boosted by plants in Spain, the UK, the US, and other EU markets such as Portugal and Italy.
