Our facilities

Our generation capacity grows by almost 4% in the first half of 2026, reaching 56,827 MW

This milestone represents an increase of 2,300 additional MW, driven by higher demand for electricity as a result of the electrification process currently under way.

We closed the first half of 2026 with a total generation capacity of 56,827 megawatts (MW), according to the energy balance report [PDF] submitted on 10 July to the Spanish National Securities Market Commission (CNMV). This strong performance is due to the growth in electricity demand across all the regions where the company operates, particularly in Continental Europe and Australia, where we have added more than 1,000 MW to our project portfolio, mainly in onshore wind.

During the same period, capacity increases in the United States also stood out, where we have added nearly 800 MW over the last 12 months, as well as in Spain (+600 MW).

By technology, offshore wind experienced the strongest growth, increasing by 16.2% to reach 2,621 MW. Solar power also showed notable growth, rising by 12.7% to a total of 9,013 MW, while storage capacity saw battery installations increase by 157.6%, reaching 683 MW.
