Marek graduated from the Faculty of Law and Administration of the University of Warsaw in 1998, also completing a course in English and European law organised by the British Centre for English and European Legal Studies at the University of Warsaw in co-operation with the University of Cambridge, and qualified as a legal advisor in 2005. Before joining Weil in 2014, from 1998 until 2011 Marek worked in an international law firm where he was the energy team leader. Between 2011 and 2013 Marek was a board member and general counsel of a leading privately owned vertically integrated energy company in Poland.
Marek specialises in the energy sector. He has advised a broad spectrum of clients involved in the energy business in Poland (e.g. generators, system operators, traders, developers, off-takers, financial institutions and equity investors).
A specialist in energy-related regulatory advice (such as licensing issues, tariffs, regulatory disputes, structuring advice, regulatory compliance, interconnection issues, EU law, and lobbying activities), Marek also has broad experience in the development of power plants, both conventional (coal- and gas-fired) and renewable (offshore and onshore wind farms, biogas and biomass installations) and related project finance transactions, as well as in the development of power and natural gas interconnector projects. In addition, he has wide experience in providing energy and natural gas trading advice (including commodity derivatives) and negotiations of long-term commercial agreements (including crude oil purchase contracts). His practice also covers M&A and privatisation transactions within the energy sector as well as corporate restructuring projects driven by the changing regulatory environment.
The prestigious legal ranking publication Chambers & Partners has ranked Marek for many years as one of the best specialists for energy & natural resources in Poland. According to the most recent report, “Marek Durski climbs up a tier due to an abundance of positive feedback. He advises a broad selection of energy market participants on regulatory, trading and transactional matters across energy generation sectors. ‘He has substantial business awareness and he's also very creative. The work he does is flawless,’ a client says. Another client adds that he is ‘always available and has a focus on problem-solving.’”
Another legal ranking, The Legal 500, has repeatedly recommended Marek for energy and natural resources. Another legal ranking, IFLR1000, has since 2014 singled out Marek as one of the few “Leading Lawyers” for energy and infrastructure in Poland.
Marek is fluent in English.
