Understanding the UK electricity grid

Live Grid Data 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.
