Iberdrola distributed 136,648 gigawatt hours (GWh) of electricity worldwide in the first half of 2026, an increase of 6.3% from a year earlier, driven by higher demand and the progress of electrification. Its power generation capacity grew by nearly 4% to 56,827 megawatts (MW), an addition of 2,300 MW, while production rose almost 1% to 61,318 GWh.
Distribution grows across every market
Distributed electricity increased in all the geographical areas where Iberdrola operates. The United Kingdom posted the largest gain, growing 32.6%, driven by the integration of Electricity North West into the company's UK distribution network.
Wind and battery storage lead new capacity
Wind technologies, onshore and offshore combined, accounted for more than 1,400 MW of the capacity Iberdrola added, followed by solar at 1,000 MW. Battery capacity grew 117%, on new operational projects in Spain and Australia.
By region, Continental Europe and Australia added more than 1,000 MW, a 23.2% increase, mainly from onshore wind in Australia, Greece and Portugal and solar in Germany and Italy.
| Region | Capacity change |
|---|---|
| Continental Europe and Australia | +23.2%, more than 1,000 MW |
| United States (past 12 months) | +7.3%, nearly 800 MW |
| Spain | About +600 MW |
| United Kingdom | +400 MW |
Production rises on offshore wind, hydro reserves near record
Iberdrola's production reached 61,318 GWh in the first half, up almost 1%, after a 2% increase in the second quarter. Offshore wind output rose 23%. By market, production grew fastest in the United Kingdom, up 27.3%, followed by the United States, up 8%, and the rest of the world, up 11.5%. Production in Spain reached 32,732 GWh, in line with the prior year.
Iberdrola's hydroelectric plants produced more than 12,000 GWh in the first half. Reservoir reserves stood near a historical record as of June 30, at more than 8,200 GWh stored, aided by the company's pumping capacity.
