137. Subsea interconnectors: new horizons - Jun24

UK is at the nexus of the subsea interconnector’s new economy. Great Britain is connected to Continental Europe by 8 interconnectors representing up to 15% of its power consumption.

Subsea cables are now a growing industry because of the benefits they bring to the grids, such as resiliency, capacity, lower prices, and renewable energy balancing. Alongside batteries and pumped Hydro, interconnectors are the best flexible green infrastructure currently available on our road to net-zero.

How has the technology evolved over the recent years? What are the economics in terms of CAPEX and OPEX? What are the revenue models? Is there a role for infrastructure investor? What are the technological challenges? How are the permitting and regulatory frameworks? How far and how deep will we go in the development of interconnectors, as we start hearing about transcontinental projects. 

To answer all those questions, we have invited Rebecca Sedler, aka “The Mother of Interconnectors” (reference to Games of Throne). After a long career at E.ON and EDF, Rebecca is Managing Director of the Interconnectors business for UK National Grid. We will start by the Viking Link, her more recent achievement, linking GB to Denmark with a 750km cable and only 3.7% loss. Finally, we will talk about the bright future of subsea interconnectors.
