A Spanish renewable-energy company that develops, owns, operates and commercializes clean-power assets and energy-transition solutions.
Last updated August 31, 2026
Overview
Acciona Energía is the renewable-energy company of Spain’s Acciona group, with headquarters in Madrid. Its activities cover the development and structuring of projects, engineering, construction, equipment supply, operations and maintenance, asset management, and the management and sale of clean energy. The company’s principal generation technologies are wind and solar power, complemented by hydroelectricity, biomass and solar thermal energy. The business was built from the renewable-energy activities associated with Acciona and its predecessor companies. An important early milestone was the commissioning in December 1994 of the Sierra del Perdón wind farm near Pamplona in Navarre, described as Spain’s first commercial wind farm. In 1995, the Acciona subsidiary Alabe also developed the KW Tarifa wind farm. Acciona later acquired Energía Hidroeléctrica de Navarra in transactions completed in 2003 and 2004, strengthening its renewable-generation platform. In 2009, Acciona obtained more than two gigawatts of renewable assets through an agreement with the Enel group connected with Acciona’s withdrawal from Endesa. The transaction substantially expanded the company’s generation portfolio and helped establish the scale of its international renewable-power business. Acciona Energía was subsequently separated as a more distinct renewable-energy platform within the group and began trading publicly on 1 July 2021 on the Madrid, Barcelona, Bilbao and Valencia stock exchanges under the ANE ticker. Acciona, S.A. remained its primary shareholder. The company combines ownership and operation of renewable assets with project development, construction services, power commercialization and customer-oriented energy solutions. Its activities include renewable electricity generation and sales, self-consumption systems, energy-efficiency services, electric-vehicle charging infrastructure, energy storage and green-hydrogen initiatives. These services are directed especially toward corporate and institutional customers, although the precise commercial offering differs by market. According to the company information summarized in the referenced Wikipedia article, Acciona Energía operated in 16 countries with 11.2 GW of installed renewable capacity and generated 24.5 TWh of renewable electricity in 2021. Its wider active presence extended to 25 countries across five continents, including markets in Europe, North America, Latin America, Australia and Africa. The company announced capacity ambitions of 20 GW by 2025 and 30 GW by 2030, with wind and solar expected to account for much of new development. These historical capacity figures and targets should be distinguished from current operating data, which require confirmation in the latest annual reports and regulatory filings. Acciona Energía also invests in innovation related to green hydrogen, offshore wind, advanced photovoltaic systems, bidirectional electric-vehicle chargers, circular-economy practices, renewable-asset life extension, predictive operations and maintenance, and energy storage. Its positioning is that of an integrated international renewable-energy developer and operator supporting electricity decarbonization rather than a conventional fossil-fuel utility.
History
Acciona Energy developed from Acciona's long-term expansion into renewable electricity. Acciona, a Spanish infrastructure group with earlier roots in construction and services, entered the modern renewable-power sector during the period when Spain was building a substantial wind and solar industry. The group's energy activities grew through a combination of project development, acquisitions, construction expertise and operation of generating assets. In 2007, the energy activity was organized as Acciona Energía, creating a dedicated platform for renewable generation and related energy services. Wind power became its leading business, supported by the company's ability to develop projects, manage construction and operate assets over long periods. The portfolio was broadened with solar photovoltaic, concentrated solar power, hydroelectricity and biomass. This technology mix reduced reliance on a single resource and allowed the company to participate in different regulatory and market environments. Internationalization became a defining feature of the business. Although Spain remained an important operating base, Acciona Energy developed and operated projects across Europe, North America, Latin America, Australia and South Africa. Its international model combined wholly owned facilities with partnerships, project companies and customer contracts. The company also expanded its commercial role by supplying renewable electricity and arranging long-term power-purchase agreements for businesses and other large consumers. The company continued to invest in solar as photovoltaic costs declined and utility-scale solar deployment accelerated. It also retained positions in hydroelectric generation and concentrated solar power, technologies that contributed dispatchability or portfolio diversification in selected markets. Its activities have included greenfield development, construction management, asset operation, electricity marketing and energy-management services. The most significant recent corporate milestone was the 2021 initial public offering of Acciona Energía. The transaction created a separately listed company on the Spanish market while Acciona remained the controlling shareholder. The listing increased the energy business's financial and governance visibility and was intended to support growth in renewable generation. It also made Acciona Energía a distinct capital-markets entity rather than only an operating division within the parent group. Since the listing, Acciona Energy has continued to focus on renewable capacity expansion, selective geographic growth and energy supply for customers seeking lower-carbon electricity. Its business environment is shaped by the global energy transition, but also by practical constraints such as permitting delays, grid availability, inflation in construction inputs, financing costs, equipment supply, power-price volatility and changes to renewable-energy support mechanisms. The company therefore combines long-term asset ownership with contracted sales and active portfolio management. It remains an operating brand of Acciona Group as well as a publicly traded renewable-energy company in its own right.

An international, vertically integrated renewable-power producer and clean-energy solutions provider focused on utility-scale generation and corporate decarbonization.
Wind powerRenewable electricity generation
Wind generation has historically been Acciona Energy's core technology. The company develops and operates onshore wind farms, manages turbines and associated electrical infrastructure, and sells the resulting power through market-based arrangements and long-term contracts. Wind projects are deployed across several of the company's international markets.
Solar photovoltaic powerRenewable electricity generation
Acciona Energy develops and operates utility-scale photovoltaic facilities. Solar has become a major growth area in the company's portfolio, complementing wind resources and enabling development in regions with strong solar irradiation. Projects can serve wholesale markets or be backed by long-term customer and power-purchase agreements.
Concentrated solar powerRenewable electricity generation
The company has operated concentrated solar-power facilities, using thermal collection technology to generate electricity. This business represents an earlier generation of large-scale solar development and provides technology diversification within the wider renewable portfolio.
Hydroelectric powerRenewable electricity generation
Acciona Energy owns or operates hydroelectric assets, including facilities that use river flows or stored water to produce renewable electricity. Hydroelectric generation adds a different production profile from variable wind and solar and contributes to portfolio management in relevant markets.
