Renewable Energy and Infrastructure

We are proud to be the main provider of legal services to renewables companies in Norway. The renewables industry is the largest onshore industry in Norway, and Thommessen has assisted developers throughout the long history of the industry.

Norway has made great progress towards a green transition, in terms of both renewable energy development and electrification. Physical and digital infrastructure projects for energy, transport, data storage and telecoms require continuous follow-up and sound project management. In-depth knowledge of peculiarities, regulatory developments and conflicting interests in the various industries provides a strong platform for attaining commercial and strategic objectives. We deliver, as both strategic and legal advisors.

We assist on all types of projects, from onshore hydropower via onshore and offshore electricity networks to offshore energy projects with floating wind turbines. Our lawyers are closely involved in development projects throughout, and assist on anything from land acquisitions, licences and contact with the authorities via construction, supply, operation and maintenance agreements, to physical and financial power purchase agreements (PPA/Corporate PPA) and financing. In addition, we have unique energy industry transaction and restructuring expertise.

Our team finds solutions and leads the way, also when the current regulatory framework is inadequate. The regulatory framework is in continuous development, and we contribute to ensuring that such framework caters adequately to the interests of our clients. Extensive industry experience, dedicated lawyers and sound project management enable us to attain the commercial objectives of renewables companies without any unnecessary detours.
