Argentina > Energy and natural resources > Electricity

The ‘definitely top-tier team’ at Estudio O’Farrell is commended for its ability to ‘strike a balance between legal analysis and business needs’ and for its ‘uniquely personalised service’. The practice, which works closely with the public law department, is best known for its track record in administrative law matters — both contentious and non-contentious — and commercial work. Senior partner Uriel O’Farrell (‘proactive with a problem-solving approach’) is highly sought after by energy companies for complex issues and co-leads the department together with Agustina Fanelli Evans (‘solid technical and commercial knowledge’) and Agustín Siboldi. On the regulatory front, the firm provides ongoing advice to Pampa Energía and Compañía General de Electricidad, among others. On the transactional side, the firm advised YPF and YPF Energía Eléctrica on a subscription agreement, which involved the sale of a 24.99% stake in YPF Energía Eléctrica’s shares to EFS Global Energy and GE Capital Global Energy Investments.

Argentina > Energy and natural resources > Oil and gas

Estudio O’Farrell’s oil and gas practice, which sits within the firm’s wider public law and economic regulation department, is best known for its ‘deep experience and knowledge of industry regulation’. Indeed, as one client points out, ‘some of its partners were even involved in the design of the current market regulation’, which is a significant benefit on complex administrative law cases. Senior partner Uriel O’Farrell is a key contact for energy regulation and disputes; he acted alongside public law expert Agustín Siboldi to represent Pampa Energía on the renegotiation of the conditions of the national incentive scheme for the production of natural gas. Axion Energy is also a key client and O’Farrell, Siboldi and Agustina Fanelli Evans advise it on day-to-day regulatory and antitrust issues.
