Islands, such as Britain, have been particularly fruitful places to develop the practice of delivering regulated and merchant interconnectors. CMS has advised on all 5GW of interconnector capacity currently in place from the UK. We are advising on seven interconnector projects in the feasibility or development phase, plus the Western HVDC Link Project.

We work ‘hand in glove’ with teams delivering these projects with a view to achieving a bankable solution, which ensures that the CMS contracts and approach effectively capture the breadth of our experience. Having advised a range of developers and on different financing strategies more broadly, we have the solutions to deliver every project. The strong global CMS network offers a combined team ready to advise on these cross-border projects across the world.

Selected relevant experience includes advising:

  • NeuConnect: The project on the procurement, construction, regulation and consenting of the NeuConnect (Germany-England) electricity interconnector. NeuConnect is a £1.4bn, 1.4 GW project traversing three countries (England, the Netherlands and Germany).
