Overview
Enel Green Power is the renewable-energy business of the Italian utility group Enel. Established as a dedicated Enel subsidiary in December 2008, it consolidated renewable-generation activities previously distributed among Enel's Italian operations and international holdings, including assets connected with Enel Investment Holding, Endesa and other regional businesses. The company develops, owns, operates and manages electricity-generating facilities using wind, solar, hydropower and geothermal resources, while also pursuing energy storage, hybrid generation, green hydrogen and advanced solar technologies. Its business is international rather than limited to a single national electricity market. Enel Green Power has operated across Europe, North and South America, Africa, Asia and Oceania. Italy remains an important base, with a large portfolio of hydroelectric, geothermal, wind and solar plants, while Spain, the United States, Brazil, Chile, Colombia, Mexico and Australia have become significant markets for development and generation. The company also participates in joint ventures and asset partnerships, allowing Enel to recycle capital while retaining exposure to renewable platforms. Examples include the Greek Principia platform with Macquarie Asset Management and the Australian Potentia Energy platform with INPEX. The company's expansion accelerated in the early 2010s. Wind projects in Brazil and the United States, including the Cristal, Rocky Ridge and Caney River facilities, broadened its presence in the Americas. Hydroelectric projects such as Palo Viejo in Guatemala added to its established hydroelectric base, and later investments expanded solar and wind portfolios in Latin America, South Africa, Australia and Europe. Enel Green Power has also used selected projects as test beds for technological integration. Its Stillwater facility in Nevada combines geothermal generation with solar technologies, while the Archimede facility in Sicily demonstrated concentrated solar power using molten salts for thermal storage. Beyond conventional generation, Enel Green Power has supported green-hydrogen research and entered agreements concerning renewable hydrogen production. It has also been involved in the 3Sun solar-module manufacturing initiative in Sicily, intended to strengthen European photovoltaic manufacturing capacity. The business has pursued a mixture of organic construction, acquisitions, minority partnerships and disposals. These transactions reflect Enel's broader strategy of concentrating on markets where it can maintain an integrated position and partnering with infrastructure investors in other territories. The company is not separately listed today. It operates within Enel's corporate structure, and its assets and strategic direction are reported as part of the wider Enel Group. Public reference material describes a portfolio exceeding 1,400 plants and approximately 66.8 GW of renewable capacity, plus storage capacity, as of 2026; these figures are time-sensitive and should be read as a dated operating snapshot rather than a permanent company attribute. Enel Green Power's positioning is that of a large-scale renewable developer and operator combining utility-grade reliability, geographically diversified generation and experimentation with technologies intended to make intermittent renewable power more flexible and dispatchable.
History
Enel Green Power was created on 1 December 2008 as Enel's dedicated renewable-energy subsidiary. Its formation gathered generation assets and development activities that had previously been managed by Enel Produzione in Italy and by international holdings associated with Enel Investment Holding, Endesa and regional subsidiaries. The creation reflected Enel's position as one of Europe's largest renewable operators and gave the group a specialized vehicle for expanding clean generation internationally. During 2011 and 2012, the company extended its wind presence across the Americas. The Cristal installation in Bahia, Brazil, was followed by Rocky Ridge in Oklahoma and Caney River in Kansas in the United States. In Guatemala, the 85 MW Palo Viejo hydroelectric plant was inaugurated in 2012. These projects established a pattern that continued throughout the following decade: combining local development with the transfer of Enel's technical, financial and operating capabilities across different renewable technologies. Enel Green Power's portfolio subsequently broadened across Europe, the Americas, Africa, Asia and Oceania. It developed or operated solar and wind facilities in countries including Mexico, Brazil, Chile, Peru, South Africa, Australia and Spain, while retaining major hydroelectric and geothermal operations in Italy. In 2014, the company received a European Solar Prize. From 2010 through 2016 it was separately listed on the Milan, Madrid, Barcelona, Bilbao and Valencia exchanges before being reintegrated into Enel's corporate structure. The company aligned parts of its industrial strategy with the United Nations Sustainable Development Goals after their adoption in 2016, particularly goals concerning education, affordable clean energy, employment and climate action. Projects mentioned in this period include the Metehara solar plant in Ethiopia, the Bungala solar project in Australia, Wayra I wind and Rubi solar in Peru, El Canadà hydroelectric generation in Guatemala, and large solar and wind developments in Mexico. In 2017, Enel also entered a long-term renewable-power arrangement with Anheuser-Busch to support Budweiser's electricity requirements from an Oklahoma wind farm. Technology development has been an important secondary theme. At Stillwater in Nevada, Enel Green Power integrated geothermal generation with solar thermal and photovoltaic systems and collaborated with United States national laboratories on research. In Sicily, the Archimede plant used concentrated solar power and molten salts to retain heat and support electricity production. Between 2020 and 2021, the company entered initiatives related to green hydrogen, including work with Eni and NextChem. From 2023 onward, Enel pursued a series of portfolio reorganizations. It sold its Romanian interests to Public Power Corporation and transferred half of its Greek renewable platform to Macquarie Asset Management, creating Principia. In Australia, Enel partnered with INPEX, first through a 50% ownership transaction and later through the creation of Potentia Energy. The company also sold selected United States assets to Ormat and advanced the 3Sun photovoltaic-module factory in Catania. These actions illustrate a capital-management model in which Enel retains strategic control of priority markets while using partnerships and disposals to fund further renewable growth. The business continues to operate as an Enel subsidiary and is not separately listed. Reference material describes more than 1,400 plants and about 66.8 GW of renewable capacity, alongside storage capacity, in a 2026 snapshot. Its current identity is that of a multinational utility-scale renewable generator, asset manager and project developer, with activities spanning mature hydroelectric and geothermal assets, fast-growing wind and solar portfolios, storage, hydrogen and manufacturing-related initiatives.
