Energy Lawyers

A key driver of the global economy, the energy sector is affected by and affects global geopolitics, economics and regulation. You require advisors who not only understand your industry but also work on cutting edge issues with leaders of energy companies, regulators, governments, industry bodies and investors.

Our teams span 42 countries and work within every part of the energy sector, including upstream and downstream oil & gas, electricity in all its forms including generation, networks, wholesale and retail markets, nuclear and renewables including solar and other green energy and clean tech. Over the last 25 years, our experts have helped shape the sector by creating the legal frameworks upon which many of your markets are based.

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. This collective experience means we can pre-empt and provide answers to the commercial, risk and regulatory issues you face in the energy sector.
