Last 5 minutes · each bar = 15 seconds

What frequency tells us

The UK grid runs at exactly 50 Hz. When demand exceeds supply, frequency falls. When supply exceeds demand, it rises.

Statutory limits are 49.5–50.5 Hz. Below 49.5 Hz triggers automatic generator trips and potential blackouts.

Dinorwig can restore frequency in 16 seconds. Grid batteries respond in under 1 second.

Current reading: frequency is below target — the grid is slightly demand-heavy right now.
