Key Points

  • A UK electricity-grid “TV pickup” incident during UEFA EURO 2020 highlighted how quickly nationwide appliance demand spikes (e.g., kettles) can create ~1 GW strain that grid operators must manage.
  • Emerald AI, alongside NVIDIA, EPRI, National Grid, and Nebius, proposes “power-flexible” AI factories that autonomously adjust power consumption during peak demand to stabilize the grid.
  • The approach is demonstrated with production-grade AI workloads at Nebius’ London AI factory, using 96 NVIDIA Blackwell Ultra GPUs and second-level GPU power telemetry via NVIDIA System Management Interface.
  • Grid stress tests simulated extreme conditions and used signals to instruct the AI factory—through Emerald AI’s Conductor Platform—to temporarily reduce power usage, reducing the need for large, slow infrastructure upgrades.
  • The concept aims to enable faster grid connections for AI customers while limiting peak load growth, potentially helping keep electricity rates more affordable.
At the half-time whistle of the UEFA EURO 2020 round of 16 football match between England and Germany, millions of viewers stepped away from their screens in the U.K. to do the same thing at the same time — turn on their kettles. National Grid, which provides electricity for England and Wales, saw a demand […]
