Event log
Simulation over — UK National Grid, 8 Jan 2024
You lasted 4 minutes. The morning shift is 8 hours. It starts again at 5am.

You were managing the UK National Grid on January 8th, 2024. A cold anticyclone had suppressed wind generation to 18% of capacity while demand hit winter peak.


Every household kettle is in the model. The Grid operations team made approximately 340 interventions before 14:00. Frequency held within statutory limits throughout.
