Iberdrola, S.A. is a Spanish multinational electric utility headquartered in the Iberdrola Tower in Bilbao and listed on the Madrid stock exchange under the ticker IBE as a member of the IBEX 35. The group combines regulated electricity networks in four main markets with one of the world's largest renewable generation fleets, and reports around 45,400 employees.
Origins and corporate structure
Iberdrola was created on 1 November 1992 through the merger of Hidroelectrica Espanola, founded in 1907 to supply Madrid and Valencia, and Iberduero, itself formed in 1944 from the union of Hidroelectrica Iberica, established in Bilbao in 1901, and Saltos del Duero. Ignacio Galan is chairman and Pedro Azagra chief executive. The Qatar Investment Authority has been the largest single shareholder, with BlackRock and Norges Bank also holding significant stakes, and the group's main subsidiaries are ScottishPower in the United Kingdom, Avangrid in the United States and Neoenergia in Brazil, alongside Elektro in Brazil and the Spanish distributor i-DE.
Networks and customers
Regulated networks are the core of the group's investment case: the company's 2026 factbook cites a network asset base of about 51 billion euros. Iberdrola distributes electricity in Spain through i-DE, in the United Kingdom through ScottishPower, in the north-eastern United States through Avangrid companies and in Brazil through Neoenergia, and the group reports serving roughly 30 million customers. Iberdrola says its first half 2026 profit growth came primarily from network investment in Britain, the United States and Brazil, alongside capital gains on asset sales in Mexico.
Generation and renewables
Group generation capacity reached 56.8 gigawatts in the first half of 2026. The factbook for 2026 records about 2,700 megawatts of renewable capacity installed during 2025 and more than 4,400 megawatts under construction, while the group's international division reported 5,443 megawatts of renewable capacity at the end of June 2026, up 24.5 percent year on year. Iberdrola's fleet spans onshore and offshore wind, solar photovoltaics, hydro and nuclear and gas generation, and the company is regularly ranked among the largest wind power producers in the world. Offshore wind has been a particular focus, with developments in the North Sea, the Baltic and the United States served through the group's regional subsidiaries.
