Iberdrola SA

Iberdrola is a multinational electric utility company headquartered in Bilbao, Spain, that was created in 1992 through the merger of several regional electricity providers. The company’s core business encompasses the generation, transmission, distribution and commercialization of electricity, as well as the sale of natural gas and related energy services. It operates a diverse generation portfolio that includes hydroelectric, nuclear, coal, gas and a growing share of renewable sources such as onshore and offshore wind, solar photovoltaic and hydro. Iberdrola supplies electricity and gas to residential, commercial and industrial customers in the countries where it maintains a presence. Through its regulated network subsidiaries it manages extensive transmission and distribution infrastructures that deliver power to millions of end‑users.

The group has a significant operational footprint in Europe, the Americas and other regions, with notable subsidiaries such as ScottishPower in the United Kingdom, Avangrid in the United States and Neoenergia in Brazil. While the exact number of customers served globally is not disclosed in the provided sources, the 2022 data breach affecting its Spanish subsidiary I‑DE Redes Eléctricas Inteligentes exposed personal data of approximately 1.3 million individuals, indicating a substantial user base in that market. Iberdrola is widely regarded as one of the leading developers of renewable energy capacity, having invested heavily in wind farms, solar parks and hydroelectric plants over the past decade. Its strategy emphasizes the expansion of low‑carbon generation and the modernization of grid infrastructure to improve efficiency and integrate distributed energy resources. The company also participates in international sustainability initiatives and is frequently included in major environmental, social and governance indices.

Distinguishing attributes of Iberdrola include its long‑standing commitment to decarbonization, which has driven early adoption of offshore wind technology and significant investments in battery storage and smart‑grid solutions. As a regulated utility, it operates under the oversight of national energy authorities in each jurisdiction, balancing regulated returns on network activities with competitive market participation in generation and retail. Structurally, Iberdrola SA is a publicly listed company on the Madrid Stock Exchange, where it forms part of the IBEX 35 index and is owned by a diversified base of institutional and retail shareholders. The subsidiary I‑DE Redes Eléctricas Inteligentes, which experienced the 2022 cyber incident, is owned by Iberdrola and is responsible for the intelligent management of the electricity distribution network in Spain. This organizational structure allows the company to combine stable, regulated cash flows from its networks with growth opportunities from its renewable generation and customer‑focused services.
