In London, CMS‘ energy and climate change practice is known for its expertise in a range of power-related matters spanning transactional, advisory and contentious work. The team notably advises clients on conventional large-scale nuclear projects, electricity transmission projects, and energy security matters. The practice is led by low-carbon projects specialist Munir Hassan, who routinely advises on the gamut of power-related matters, from generation to networks. On the contentious side, Philip Ashley is a key contact for international arbitration, commercial litigation, and regulatory investigations in the energy sector, while Dalia Majumder-Russell’s broad practice spans energy transactions, commercial agreements, and regulatory work. Nuclear power specialist Matthew Honeyben - who joined the team from Eversheds Sutherland (International) LLP in May 2023 - advises clients on all aspects of nuclear new build projects including procurement strategies, project structuring, power purchase agreements, and joint ventures.
