A UK trial demonstrated that data centers can modify electricity consumption in response to grid signals using AI technology. Led by National Grid with partners Emerald AI, EPRI, Nebius, and NVIDIA, the trial took place at a London data center using Emerald AI's 'Emerald Conductor' software to manage 96 NVIDIA Blackwell Ultra GPUs.

The system reduced electricity demand by up to 40% during over 200 simulated grid events. It also lowered load by approximately 30% within 30 seconds during stress tests. This approach may help reduce grid constraints and support renewable energy connections, allowing for more efficient management of electricity demand as the digital economy grows.
