Emerald Conductor is Emerald AI’s software platform for coordinating data-center computing with grid conditions. It uses grid signals, facility telemetry, and workload information to adjust AI workloads and power consumption while aiming to preserve critical workloads. In a Phoenix field demonstration, the system reduced cluster power use by 25% for three hours while maintaining AI quality-of-service guarantees. In a London trial, it responded to more than 200 simulated grid events, with reported reductions of up to 40%. The platform has also been demonstrated with data-center and grid partners.
