WiersholmLauded by clients for its ability to bring ‘a wealth of experience and technical know-how to transactions’, the energy team at Wiersholm runs the gamut of renewable and traditional energy work, handling commercial agreements, project financing work, regulations, and project development. Inge Ekker Bartnes and Jon Rabben jointly oversee the renewables offering; Bartnes is recommended for work relating to M&A, financing deals, and financial restructurings, while Rabben assists domestic and international clients with regulatory issues, contract negotiations, and corporate matters. On the oil and gas front, the team’s expertise spans the full range of petroleum law and regulatory work, as well as commercial agreements, disputes, and transactional mandates. Sondre Dyrland oversees the oil and gas group and has extensive expertise in petroleum law and contractual matters, while Thomas Naalsund handles contentious work. At associate level, the ‘technically very sharp’ Svanhild Vesterheim specialises in regulatory matters in the renewable energy sector. Torkjel Grøndalen joined the practice in early 2024 from Advokatfirmaet Schjødt.
