Power and Nuclear

We have significant experience in the power sector, including in thermal generation, nuclear power, as well as electricity storage, networks, and supply. Our clients frequently come to us for advice on  innovative and pioneering energy projects, embodied by novel structures and tailored contracts that demand a bespoke approach. From groundbreaking nuclear power initiatives to pioneering carbon capture plus power projects, we are at the forefront of transformative developments in the sector, both in the UK and internationally.

We frequently represent a variety of stakeholders in the market, including utilities, independent power producers, investors, project sponsors, network operators, funds, financial institutions, and governmental bodies. Our track record includes advising on the first nuclear power station to be constructed in the UK in over two decades, marking a significant milestone in the country's energy landscape. Additionally, we were instrumental in shaping the regulatory framework for the first renewables Contracts for Difference (CfDs).

Whether it's navigating regulatory hurdles, structuring bespoke agreements, or mitigating risks inherent in project delivery, our comprehensive approach ensures that clients receive tailored solutions that meet the unique demands of their projects.

We advised EDF Energy on the entry into revised arrangements with the UK government and the Nuclear Decommissioning Authority (NDA) to deliver the safe and efficient decommissioning of the UK’s seven advanced gas cooled reactor (AGR) power stations.

We advised ENGIE S.A. in relation to its negotiations with the Belgian Government concerning a ten-year lifetime extension of two nuclear units. The project includes the structuring and joint venture arrangements between ENGIE and the Belgian State; a new cap on liability for nuclear waste; a contract for difference and remuneration mechanism; and new O&M arrangements in relation to the two nuclear units.

This is a significant project for ENGIE, as it represents a change of strategic direction with respect to Belgian nuclear power and it will involve an unprecedented lifetime extension for its Belgian nuclear assets on a challenging timetable, requiring a large-scale mobilisation of its human and operational resources.
