Can We Stop Data Centres Breaking The Grid? Ep249: Varun Sivaram & Steve Smith

This week on Cleaning Up , host Michael Liebreich sits down with Varun Sivaram and Steve Smith to explore one of the most urgent, and overlooked, challenges of the AI revolution: how to power it without breaking the grid. As AI demand explodes, hyperscale data centres are emerging as massive, inflexible loads, rivaling entire cities. But do they have to be a burden on the grid? This conversation dives into a groundbreaking trial led by Emerald AI in partnership with National Grid and NVIDIA—demonstrating that data centres can dynamically adjust their power consumption in real time using software. Key insights include: How AI data centres could reduce grid stress instead of increasing it The concept of “flexible demand” and why it’s a game changer for AI data centres Real-world trial results Why “speed to power” matters more than cheap electricity in the AI race How software, not infrastructure, could help unlock billions in grid capacity The hidden flexibility inside AI workloads (and why not all compute is equal) From kettle spikes during football matches to lightning strikes on the grid, this episode reveals how intelligent systems can respond in seconds, turning a looming energy crisis into a massive opportunity.
