‘Skilled and trustworthy.’

‘We find that the practice has very good knowledge when it comes to the utility sector in which we operate. They are quick to identify the problem we are facing and help us focus on the issue of most importance.’

‘I have found their main strength to be their broad understanding of the electrical utility sector in Norway and the complex legal challenges that the grid companies encounter.’

‘Great team bringing together regulatory knowledge, business experience and construction law experience. The team is outstanding in cooperating but also guiding other supporting parties like technical and commercial advisors.’
