The energy sector is used to change, but it has never faced greater adjustment than it does today. The biggest issue of our time is how to meet our energy needs in a way that sustains the future of the planet, while also sustaining the sector itself, which is essential to our society.

Unlike some sectors, where maturity has brought extensive standardisation and commoditising, the energy sector is seeing an increase in new approaches and practices either on climate change strategy and new technology, oil & gas exploration and energy efficiency, project finance or M&A, energy disputes and regulation.

Whatever your opportunities or challenges may be, our team is specially designed to understand your business needs and advises companies on how to comply with energy law.

We can help you shape your strategy, manage risks and make the most of business opportunities in these areas:

  • Oil & Gas Exploration and Production
  • Traditional or newer electricity generation technologies
  • Energy transition and climate change strategies
  • Energy Efficiency
  • Project Finance
  • M&A
  • Disputes or Regulatory and Commercial issues

We have an in-depth knowledge of how energy law applies in practice across different markets and with cross-disciplinary teams, we work to provide advice close to our clients’ needs.
