Acciona, S.A. is a globally diversified Spanish conglomerate specializing in sustainable infrastructure and renewable energy solutions. Founded over a century ago, the company has evolved from a traditional construction firm into a sustainability pioneer, focusing on the energy transition and the decarbonization of the global economy. Acciona operates across two main divisions: Energy, where it is one of the world’s largest owners and operators of renewable generation assets (notably wind, solar, hydro, and biomass), and Infrastructure, which encompasses construction, water treatment, transport, and urban services. The group also maintains significant interests in wind turbine manufacturing through its stake in Nordex, as well as other activities like property development, facility management, and electric urban mobility. With a strong international footprint—72% of revenues come from outside Spain—Acciona is recognized for its commitment to environmental, social, and governance (ESG) principles and its role in developing large-scale, greenfield infrastructure projects. Its robust project backlog and focus on concession-based assets underpin a stable, long-term business model, making Acciona a notable player in the global push toward sustainable development and a key constituent in European industrial and renewable energy markets.
