Live scheduled flows on GB's electricity interconnectors. Green lines show power flowing into GB (import); orange lines show power flowing out of GB (export). Line weight is proportional to flow relative to cable capacity.
Physical Notifications (PN dataset) — scheduled import/export flows per interconnector Balancing Mechanism Unit, published in half-hourly settlement periods. Data is typically 15–45 minutes behind real time.

Flows are Physical Notifications rather than metered actuals, so figures represent scheduled rather than real-time MW. GB interconnectors are operated independently; Moyle and East-West Link connect GB/Ireland electricity markets, which operate separate balancing mechanisms.
