Our facilities
We achieved a record 255,976 GWh of electricity distributed in 2025 thanks to strong growth in the United Kingdom
This milestone represents a 7.5% increase, which has been achieved thanks to higher demand for electricity as a result of the electrification process we are currently undergoing.
Electricity distributed by Iberdrola worldwide during the 2025 financial year increased by 7.5%, reaching 255,976 gigawatt-hours (GWh), according to data from the energy balance [PDF] corresponding to the results presented to the CNMV on 6 February 2026. This growth was driven by the business in the UK (+52.2%), including the contribution from Electricity North West.
This strong performance in distribution, resulting from increased demand and electrification, was accompanied by a rise in installed capacity, which stood at 58,343 MW (+3.2%). Of this total, 40.5% corresponds to onshore and offshore wind, 22% to hydroelectric power and 15% to solar. There was also a notable increase in battery storage capacity, which reached 683 MW, with developments in Australia, Spain and the UK.

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.
