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.
