Electricity in Peru

Hernández & Cía. Abogados

The numerically small team at Hernández & Cía. Abogados punches above its weight advising a strong client roster on the entire life-cycle of electricity projects, from financing and drafting construction contracts through to the regulatory aspects of project development, interconnection and operational matters. Clients, comprising a broad mix of electricity and renewable energy companies, financiers and developers, highlight the firm's 'extensive experience’ in the sector and its 'availability, knowledge and careful management’. Lead partner (and current President of Peru's Renewable Energy Society), Brendan Oviedo enjoys a high profile across the sector; he leads a 'well-organised’ team comprising senior associate Evelyn Lopez (who's past experience includes five years at COES), and associate Daniela Falcone (environment, energy and infrastructure projects) who does 'excellent work’; both are recommended by clients.

Practice head(s):

Brendan Oviedo


It is a team with extensive and recognised experience in the energy sector, and they are always actively participating in possible changes and in regulatory debates. A point to highlight is also the flexibility they have and the ability to provide solutions.’

Recognised experience far superior to the competition and very quick response to urgent orders. Brendan Oviedo is a flagship energy partner and has a very well organised team, where Evelyn Lopez  and Daniela Falcone stand out.’

I feel that it is very easy for them to understand my issues and to support us. I think they work well as a team. They have always solved our problems positively.’

Brendan Oviedo is very knowledgeable about the energy sector. He is very willing to help and seek solutions for our problems. Very easy to communicate with him.’

Leader in the Peruvian electricity sector.’

Hernández & Cía. Abogados are always available. We have worked with them on some legal agreements on electrical connectivity and they have advised efficiently, they have been accessible all the time and have valuable experience in the electricity sector and in the Peruvian electricity market.’

Their availability, knowledge and careful management are highlights. Brendan OviedoEvelyn Lopez and Daniela Falcone are recommended. The management of this team is agile and they do their best to obtain the requested results.’

The Hernández energy team has excellent legal and casuistic knowledge of the electricity sector. One of their greatest strengths is the great knowledge and understanding of the technical aspects of the projects, which allows them to provide solutions that go beyond the legal and obtain the expected results. Likewise, it is not common for energy lawyers to dominate other areas, but the Hernández energy team has an excellent command of the various aspects that involve the development of an electrical project (property, environmental, regulatory, etc), which allows us to lean on them in more than one subject. Brendan Oviedo and Daniela Falcone do excellent work.’

Grenergy has worked with Estudio Hernandez on different agreements for the connection of its wind and solar projects. The team in charge: Brendan Oviedo and Evelyn Lopez, have shown commitment and professionalism in their assignments, which has given us great satisfaction. They have sufficient cross-cutting knowledge, not only electrical regulatory but also financial, environmental and social. The team has been orderly, committed, proactive and methodical in achieving our goals and objectives. We have had the opportunity to work with Brendan Oviedo and Evelyn Lopez who have solid regulatory and technical knowledge of the electricity market, which has helped us strategically propose the legal strategies of the company.’

High standard energy experts for the market, agility in response, creativity and experience in solutions. Brendan Oviedo: very good in the strategy process leading to very good final results.’

The firm advises us on all M&A issues, both at the documentary and regulatory levels, and lately regarding the replacement of solar panels in our renewable energy plants in Peru. Its knowledge of the public sector has not allowed to obtain in a timely manner various permits related to share transfers and especially the Legal Stability Agreements. I’d highlight the firm’s transversal knowledge of not only electrical but also financial regulatory.’

Their knowledge of the Peruvian electricity sector, as well as the commercial approach they manage, makes them a strategic ally when analysing our investment opportunities.

Luis Marcelo De-Bernardis is a benchmark in the electricity sector. He knows each of the subsectors (generation, transmission, distribution) very closely, so his advice is usually holistic, which generates a high added value. Associate Pedro A. Morales is a specialist in regulatory issues in the sector. His experience, the product of having worked in the Economic Operation Committee of the Peruvian electricity system (COES), makes him an important ally when negotiating trade agreements. Finally, we highlight the work of César Ramírez, an associate of the firm, who has led several due diligence exercises. His impeccable work has allowed us to identify significant risks in order to make an investment decision, allowing us to eliminate them or mitigate their impact in a timely manner.’
