Iberdrola today

Iberdrola is Europe’s leading electricity utility and one of the two largest in the world

Thanks to our century-long track record, Iberdrola is now a global energy leader and the world’s leading wind power producer. We are the world’s second-largest electricity company and Europe’s largest by market capitalisation, exceeding €135 billion in February 2026.

At Iberdrola, we are driving innovation and a sustainable, competitive business model that creates value for society as a whole, while taking into account a context in which electrification is advancing at an unstoppable pace.

Over the past 25 years, we have had a clear goal: to build infrastructure capable of bringing light and energy to homes and industries around the world. To achieve this, we have focused on three fundamental pillars: a diversified portfolio of electricity generation sources, an increasingly smart electrical network and a close relationship with our customers to create tailored solutions.

By following this path, we have multiplied our market capitalisation by 12, creating €123 billion in value over the period. We have also increased our total assets eightfold and our regulated assets tenfold, reaching an installed capacity of 58,000 MW compared to 16,000 MW in 2001. This has been our journey over the past quarter of a century.

We are also continuing on our mission to strengthen smart grids, large-scale energy storage and the digital transformation to offer our customers the most advanced products and services.
