Measured interconnector outflow
Exports are power flowing from GB to connected neighbouring grids. This is split from interconnector flow where the live feed reports a negative value.
Net Balance
-1.63 GW
Demand above tracked supply
Net Balance is tracked generation minus demand and measured exports. A small difference is normal because of storage, losses, timing differences and data that is not separately identified.
iInterconnector flow is split into imports into GB and exports out of GB where available. Remaining balance may include storage, losses, timing differences and untracked generation.

Understanding the UK electricity grid
Live Grid Data UK shows a near real-time view of the Great Britain electricity system, including current demand,
generation by source, interconnector flows, exports, clean electricity share and carbon intensity.
The dashboard updates every 15 minutes using publicly available electricity market and carbon intensity data.
What is electricity demand?
Electricity demand is the amount of power being used across the grid at a point in time.
What are interconnectors?
Interconnectors are high-voltage cables linking Great Britain with neighbouring electricity markets, allowing imports and exports.
What does carbon intensity mean?
Carbon intensity estimates the amount of carbon dioxide emitted for each unit of electricity generated.
