As wind and solar ramp up in Europe and Great Britain, one thing becomes clear - clean energy works better when it’s connected.

Interconnectors are high capacity cables linking electricity grids between countries, and are critical to making the most of renewable power. They help move surplus wind across borders, balance supply and demand in real time, and can help reduce costs for consumers. The more we build, the more efficiently we can use clean energy across the whole of the UK and Europe.

In this episode of Transmission, Rebecca Sedler, Managing Director of Interconnectors at National Grid, joins Ed to explain how these workhorses of the energy system operate and why they’re set to play an even bigger role in the future grid.

Over the conversation, we’ll explore:

• How interconnectors enable cross-border power flows and real-time system balancing.

• How the UK moves electricity in and out of Europe in real time.

• The role of interconnectors in reducing curtailment and maximising renewable asset utilisation.

• Market coupling, price convergence, and the impact on system cost and consumer bills.

• How projects like LionLink could help build a North Sea power grid.
