Enel Green Power S.p.A. is an Italian multinational renewable energy corporation, headquartered in Rome. The company was formed as a subsidiary of the power generation firm Enel in December 2008, grouping its global renewable energy interests. Enel Green Power has operations in over 16 countries across Europe, North and South America. It generates energy principally from hydroelectricity, wind, solar power, geothermal electricity and biomass sources. At the end of September 2011, the company's total worldwide installed capacity was 6,490 MW, which it intends to increase to 10,400 MW by 2015.

A 30.8% stake in the company was floated on the Borsa Italiana and Bolsa de Madrid in November 2010, raising €2.6 billion and marking the largest initial public offering in Europe since that of Iberdrola Renovables in December 2007.[2] In 2014, the company was presented with a European Solar Prize by Eurosolar. [3]


Enel Green Power was founded on the 1st of December 2008 to concentrate all of Enel’s activities in the production of renewable energy. At the time of its establishment, Enel Green Power was the largest European company in the field of renewable energy both in terms of installed capacity and international presence[4]. 

Following its foundation, the activities of the renewable energy branch which were until then held by Enel Produzione SpA in Italy, and those belonging to Enel Investment Holding abroad (Enel Latin America BV, Erelis Enel, Endesa), have been gradually transferred to Enel Green Power[4]. 

In November 2010, following Enel’s acquisition of Endesa (June 2009), the company made an initial public offering of 30.8% of Enel Green Power in the Italian Stock Exchange and the Bolsa de Madrid, earning the company 2.6 billions of Euros. In Italy and Spain, the IPO of Enel Green Power was handled by PricewaterhouseCoopers and involved about 340 thousand investors, generating a demand of about 1,260 million shares (of which 520 million subscribed of institutional investors)[5]. The company is listed on the stock markets of Milan and Madrid and on the regional stock exchanges of Barcelona, Bilbao and Valencia.




More than half of Enel Green Power’s plants are located in Italy, for a net installed capacity of around 2,830 MW. The production mix includes Geothermal electricity, hydroelectricity, wind, Solar power, whose development had a strong boost in 2011 and will be emphasized in the coming years.

Enel Green Power is also a leader in geothermal, with 34 power plants located in Tuscany, representing a capacity of 728 MW and providing an annual production of over 5 billion kWh. The company is a world reference for this technology. It initiated its first center in the area of Larderello in Tuscany, as early as the beginning of last century.

Wind energy has had the greatest growth in Italy since the beginning of the 21st century, including ENEL facilities.

In the field of solar energy, Enel Green Power developed the franchisee model in Italy of Enel Green Power Retail. In addition, a thin-film photovoltaic panels factory was inaugurated in 2011 in Catania, through a joint venture with Sharp and ST-Microelectronics. The generation of electricity from solar energy is coming from 67 MW installed in 2011, (data as of the end of September).

Iberian Peninsula[edit]

Enel Green power has facilities in the Iberian Peninsula thorough a total installed capacity of 1,707 MW and 120 plants. This presence is the result of the integration of renewable energy activities of Enel and Endesa. The wind technology, with about 90 plants for a net installed capacity of 1,530, has the biggest share. The production mix includes mini-hydro with about 10 plants for 57MW, solar with 3 plants for 14MW, and cogeneration and biomass with 20 plants representing 107MW

Eastern Europe[edit]

Enel Green Power has substantial presence in Romania, which has recently launched a major program to support investments in renewables. At the end of 2012, Enel Green Power had five operating wind farms with an installed capacity of 292MW, and another 206MW under construction.[6] Enel Green Power is also present in Bulgaria with two wind farms representing 42 MW.

Other countries[edit]


Enel Green Power, has 10 wind farms with an installed capacity of 166 MW ; its strategy is to develop facilities to make use of on-shore wind, while continuing to evaluate possible investments in photovoltaic.


Enel Green Power is present in Greece, with 14 wind farms for a net installed capacity of 172 MW and 5 hydroelectric plants for 14 MW.

North America[edit]

In North America, Enel Green Power has an overall capacity of 786 MW across four technologies. In the United States Enel Green Power owns more than 60 hydroelectric plants (313 MW of installed capacity), 21 wind farms (378 MW of net installed), and 2 geothermal plants (47 MW of net installed). In Canada it has a biomass plant (21 MW of net installed capacity) and a wind farm (27 MW of net installed capacity).

EGP started operations of the first hybrid solar-geothermal plant at the Stillwater site in Nevada. 17MW of geothermal are also in development in Cove Fort. Enel Green Power completed at the end of 2011 the 200MW Caney River wind farm in Kansas, and initiated construction of the 150MW Rocky Ridge plant in Oklahoma.

Latin America[edit]

Enel Green Power has a presence in Central and South America with 34 plants spread across Mexico, Costa Rica, Guatemala, Nicaragua, Panama, Chile and Brazil. In addition Enel Green Power owns a stake in a company in El Salvador which operates a geothermal plant. Enel Green Power currently has 32 hydroelectric plants with an installed capacity of 645MW of which one plant in Panama accounting for 300 MW - the second infrastructure after the Canal - generating 25% of the country. It is also building in Guatemala, in the region of Quiche, the run of the river hydroelectric plant in Palo Viejo with a capacity of 85 MW and in Costa Rica the Chucas hydroelectric plant with a capacity of 50MW. Enel Green Power also owns a 24 MW of wind farm in Tilaran, Costa Rica. It recently won an the auction in Brazil to develop an additional 193MW, to be added to the 90MW awarded at a previous auction.

Recent Events[edit]

On Nov. 11, 2014, the United States Attorney for the Northern District of Oklahoma filed suit against Enel's subsidiary. Osage Wind LLC, an 84-turbine industrial wind project in Osage County, Okla.[7] In the suit, the United States alleges that Enel and Osage Wind are illegally converting minerals owned by the Osage Nation, a Native American tribe that has owned all mineral rights in the county since 1871. [8]The suit says that Osage Wind should have obtained a permit from the Bureau of Indian Affairs before mining rock and other material for the pits in which turbine bases are built. The United States asked that all excavating on the 8,500 acre site cease and that dozens of turbines that are already being erected be removed.[9] Osage Wind has insisted that it is not mining and needs no permit. The company says that it has already spent nearly $300 million on the project, which is being built on privately owned fee land, not land held in trust for American Indians. [10]

Osage Wind LLC and a second and adjacent Enel wind project, Mustang Run, are also embroiled in challenges pending before the Oklahoma Supreme Court in which the Osage Nation and Osage County, Okla., are challenging the constitutional legitimacy of permits for both projects. [11][12]

On February 3, 2015, a turbine at the hydropower plant at Barber Dam, Boise, Idaho, turned off. A regional operations manager for Enel says it's not clear what caused the shut down, and that an alert system also failed. Boise River water normally flows through at 240 cubic feet per second, but that night it dipped to less than 60 cfs. Several local, state, and federal agencies are now looking into the incident, and its effects. Idaho Rivers United says even though it's hard to measure the impact, it's an important issue. "The damage is invisible right now but that doesn't mean there wasn't a lot of harm done to the river." The low water level stretched 10 to 15 miles downstream, and brought the Boise River to its driest point in decades. Idaho Fish and Game says they did find some dead fish, and although they believe while adult fish weren't impacted, younger ones could have been. "We think there was some impact to wild brown trout and small young of the year mountain whitefish, as well as the food base... this event could have been potentially damaging to that age class of wild brown trout and wild mountain whitefish," said Joe Kozfkay, Idaho Fish and Game Regional Fish Manager.[7]
