Estudio O'Farrell

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.

Beccar Varela

Beccar Varela’s profile continues to grow in the power area, particularly on the renewables side, as evidenced by an increasingly impressive client roster which includes Canadian Solar, Goldwind International Holdings (HK) and Solarpack. The firm is well versed across the full spread of generation, transmission and distribution-related issues, with an emphasis on regulatory and transactional matters. Energy expert José Carlos Cueva is the key contact and recently advised Hive Energy (UK) on its plans to develop solar power plants in Argentina.

Mariano Luchetti, who co-leads the group, is also recommended. AES Energy, Equinor and Invenergy are also on the department’s books.

Díaz Bobillo, Vittone & Asociados

Very strong boutique’ Díaz Bobillo, Sigwald & Vittone Abogados is highlighted by peers and clients alike for ‘punching above its weight’ in the power sphere. The firm attracts strong praise for its ‘broad and well-rounded practice’ — it certainly handles a wide range of contentious and non-contentious matters — but its ‘leading regulatory law capability’ is the feature that particularly stands out. Founding partner Víctor Díaz Bobillo ‘knows the power market inside out’ and is highly recommended for regulatory, contractual and arbitral issues.

Martínez de Hoz & Rueda

Martínez de Hoz & Rueda’s power practice, which is highlighted by peers as ‘very strong and growing quickly’, is distinguished by its ‘specialist project finance expertise’ as well as by its ‘deep experience in complex administrative law matters’.

High-profile figure Héctor Pozo Gowland stands as a ‘market leader in energy and public utilities law’.

Tavarone, Rovelli, Salim & Miani

The ‘very strong team’ at Tavarone, Rovelli, Salim & Miani impresses with its ‘effective combination of regulatory and transactional expertise’.

Bomchil’s power practice is distinguished by its concentration on complex contentious matters, particularly arbitration. Despite the recent departure of arbitration expert Guido Tawil, the group’s strategic focus on administrative law matters is expected to continue with the appointments of regulatory specialists María Inés Corrá (‘deeply committed and solution-oriented’) and Francisco Gutiérrez as the new department co-heads. Highlights included successfully representing Wintershall Energía in a $250m claim brought by a Chilean gas distributor against a consortium of Argentine producers related to export restrictions.

Cassagne Abogados
