Naturgy Energy Group S.A., formerly Gas Natural Fenosa (Spanish pronunciation: [ˈɡas natuˈɾal feˈnosa]), is a Spanish multinational natural gas and electrical energy utilities company, which operates primarily in Spain. The company's administrative headquarters are in Barcelona, while its legal headquarters are in Madrid.[2]

It also has operations in other countries, including: Italy, France, Germany, The Netherlands, Belgium, Mexico, Colombia, Argentina, Brazil, Moldova, and Morocco, as well as the U.S. territory of Puerto Rico.


The corporation's main interests are: the distribution of natural gas in Spain, Italy, and Latin America; the generation and commercialisation of electricity in the liberalised Spanish market (1997-2009);[3] and the management of natural gas infrastructure and shipping transport.

Gas Natural has approximately 10,000,000 energy clients worldwide. It has around 6,700 employees, of which approximately 50% work within Spain.[citation needed]

The group's largest shareholders include the Spanish La Caixa bank and Repsol global energy company.[citation needed]

Gas Natural acquired utility company Unión Fenosa for around €16.8 billion in 2009.[4]

In June 2018, the general shareholders meeting of Gas Natural approved the change of name of the company to Naturgy Energy Group.[5]


The company's administrative headquarters complex, Gas Natural Building or Mare Nostrum Tower, is located in the La Barceloneta neighbourhood of the Ciutat Vella district in Barcelona. The skyscraper was designed in the High-tech architectural style by the EMBT Architects firm of architects Enric Miralles and Benedetta Tagliabue, and was completed in 2005.

Its legal headquarters were moved to Madrid in 2017, because of the Catalonia independence crisis.[6][7] Naturgy's Madrid headquarter complex is located in the district of Hortaleza. These headquarters are a building complex of 14 buildings that Naturgy bought in 2016.[8]
