Energy Lawyers

A key driver of the global economy, the energy sector is affected by geopolitical, economic and regulatory pressures. You require advisors who understand your industry and work with leaders of energy companies, regulators, governments, industry bodies and investors on the cutting edge of commercial, regulatory and risk issues in the sector. Based across 15 jurisdictions in Central and Eastern Europe, we have been active in CEE since the beginning of the privatisation and liberalisation of the energy sector across the region. We have helped to shape the sector by advising on the most high-profile and ground-breaking projects and transactions over many years.

Our dedicated energy lawyers work in every part of the sector, including upstream and downstream oil & gas, electricity, nuclear and renewables.  Whether you are a NOC, IOC, independent, electricity company, investor, government or financial institution, we have the energy specialists to meet all your strategic challenges globally. Our multi-disciplinary teams were among the first to advise on ground-breaking global oil and gas M&A and on power projects in Europe, to establish a single electricity market in Northern Ireland and the Republic of Ireland, lead historic electricity industry reform in Mexico, and work on renewable energy projects globally.

Our Ukraine Energy Projects and Construction practice group is consistently recognised as being the leading energy practice in Ukraine by both international and local rating agencies (Chambers Europe 2012-2016, The Legal 500, 2015-2016 and Ukrainian Law Firms 2009-2015).

We advise clients from across of the energy industry (power generation and oil & gas) on how to structure projects, offering not only legal expertise but also wide-ranging knowledge of the industry and its technical and physical characteristics. Our specialists also cover associated legal fields, including real estate law, construction law, infrastructure regulation, environmental law and corporate law.
