We are the premier one-stop shop for any matters related to the Brazilian power sector, especially for the most complex and sensitive issues our clients may face. Our work includes high-level regulatory advice, administrative and judicial litigation, arbitration, projects, and M&A. We work across all segments of the Brazilian power sector: distribution, transmission, generation (including distributed generation), and trading.
By providing constant legal advice to the major players in the sector (e.g. Enel Group, Equatorial Group, Neoenergia Group, and Elera Renováveis), associations of the sector (e.g. ABRADEE) and forefront entrepreneurs, and by maintaining constant contact with the Brazilian Power Sector Regulatory Agency (“ANEEL”) since the creation of the Agency, Ulhôa Canto has acquired deep familiarity with the issues being discussed in the sector over the years and is able to provide very consistent strategic advice to the clients.
