The energy practice is co-headed by Xavier Remy, who advises distribution service operators and energy suppliers on high-value corporate, commercial, and regulatory matters, particularly concerning the energy transition. Also co-leading the team, Patrice Viaene brings a breadth of knowhow across the electricity and renewable energy space, advising leading power project companies and electricity system operators on construction contracts, power and hydrogen offtake agreements, and renewable asset tenders. Philippe Baert provides key support. David Ballegeer joined the firm in April 2026.
