en.Wedoany.com Reported - Iberdrola's global electricity distribution volume grew by 6.3% in the first half of 2026, reaching 136,648 GWh, driven by rising electricity demand and the electrification process. During the same period, the company's installed generation capacity increased by nearly 4% year-on-year to 56,827 MW, with a net addition of 2,300 MW. The new capacity primarily came from wind power (onshore and offshore), totaling over 1,400 MW, followed by solar power with an additional 1,000 MW. Battery energy storage capacity surged by 117%, benefiting from new projects in Spain and Australia.

Geographically, capacity in continental Europe and Australia increased by 23.2%, adding over 1,000 MW, mainly from onshore wind in Australia, Greece, and Portugal, as well as solar power in Germany and Italy. In the United States, nearly 800 MW were added over the past 12 months, representing a 7.3% increase; the United Kingdom added 400 MW; and Spain grew by approximately 600 MW.

In the first half of 2026, Iberdrola's electricity generation reached 61,318 GWh, up nearly 1% year-on-year, with the second quarter contributing a 2% increase. By technology, offshore wind performed the strongest, with generation rising by 23%. By market, the United Kingdom (up 27.3%), the United States (up 8%), and the rest of the world (up 11.5%) led the growth.

Electricity generation in Spain stood at 32,732 GWh, flat compared to the same period last year. Although hydropower generation exceeded 12,000 GWh in the first half, reservoir storage remained near record levels as of June 30, with over 8,200 GWh stored, benefiting from pumped storage capacity.
