Our distributed electricity sets its record in the first half of 2025 with over 124,000 GWh

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. Meanwhile, the Group's total renewable capacity has exceeded 45,000 MW for the first time.

We reached maximums in electricity distributed by the Iberdrola Group at the end of the first half of 2025, exceeding 124,000 GWh, according to the data from the energy balance sheet data [PDF] for the first half of 2025. 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.

On the other hand, 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%), Brazil (+11.7%) and Spain (+6.4%) were particularly noteworthy.

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, with a growth of around 4%, and now accounts for 79% of the Group's total capacity.

About the Iberdrola Group capacity map

The Iberdrola facility map is an interactive way of viewing the company's main global operating data: the installed capacity of each technology, net electricity production and other data including distributed power, supply points and the group's customers in all the countries in which we operate.

The information on this map is updated every quarter, based on the results for the period, and it breaks down the installed capacity in each country and region according to the electricity generation technologies operated by the group: renewables (onshore wind, offshore wind, hydroelectric, mini-hydraulic, battery storage, solar and others); nuclear; combined cycle and cogeneration.
