Kinstellar announces new promotions to Partner and Counsel

April 2021 – Kinstellar is delighted to announce the promotions to Partner of Balázs Sepsey (Budapest), and to Counsel of Tomáš Melišek (Bratislava), Alexandru Mocănescu (Bucharest) and Nina Tsifudina (Sofia).


Balázs Sepsey, Budapest

Balázs has over 17 years of experience advising Hungarian and international companies on a wide range of energy-sector matters, including energy-related M&A deals, power plant development projects, long-term supply agreements, EPC contracts and EU energy regulatory work. His expertise extends to energy infrastructure projects, mid- and long-term power purchase and gas supply agreements, energy project agreements, petrochemical revamp and development projects, and regulatory issues in the field of energy law. Balázs has a particular focus on EU energy law, including regulatory advice and energy-related state aid and competition law matters.

Having worked for more than a decade closely with Kristóf Ferenczi, the firm-wide head of the Energy & Natural Resources practice and the Managing Partner of our Budapest office, Balázs has been responsible for the day-to-day work of the Budapest Energy & Natural Resources team in Hungary. He has also been instrumental in a suite of cross-border energy sector matters, assisting the regional energy sector team across our jurisdictions.

Balázs has coordinated and led the most recent and acclaimed energy matters of the Budapest office, including:

  • the natural gas sale & purchase aspects of the establishment of a joint venture between two major energy companies for the implementation of a large-scale natural gas exploration project;
  • the negotiation of two long-term natural gas sale and purchase agreements relating to an off-shore natural gas exploration project with a value in excess of USD 8 billion;
  • the development of five photovoltaic power plant projects in Hungary with an aggregate built in capacity in excess of 150 MW;
  • various energy regulatory aspects of the Hungarian law implementation of the so-called EU Clean Energy Package, the most significant regulatory change in the Hungarian power sector legislation in the last decade;
  • the acquisition of the largest Hungarian natural distribution system operator company;
  • the implementation of an innovative digital consumer product for a large Hungarian energy company that will provide a state-of-the-art digital experience for customers. The project raised novel and complex energy regulatory, consumer protection, data protection and digitalisation issues, which had not been dealt with previously in Hungary.

Balázs has been with Kinstellar since 2005. He was promoted to Managing Associate in 2016 and to Counsel in 2018. His exceptional expertise, professionalism and attitude have contributed significantly to the success and high-quality service of the Tier 1 Energy & Natural Resources team and practice in Hungary. Balázs is ranked in Band 3 by Chambers Europe and is recognised as a Rising Star by Legal 500 and IFLR 1000. Clients describe him as "very accurate, quick and solution-orientated" and someone who “understands the merit of the case very quickly” and who has “a practical business-oriented approach”.
