Some emerging countries have stood out with strong companies presence in foreign markets, competing head-to-head in sectors traditionally dominated before by multinationals from developed economies. The present study describes and analyzes the characteristics of the internationalization of Eletrobras, a particular case of a state owned company that competes in a regulated sector. Based on interviews with company executives and secondary data, the study outlines the motivations for internationalization, the criteria for selecting countries and entry modes used by Eletrobras. The analysis of this specific case, through the lenses of the major theories of internationalization and typologies of multinationals from emerging countries, contributes to a better understanding of the phenomenon of internationalization of companies from emerging countries.
