## Summary

Brian Janous, former VP of Energy at Microsoft and co-founder of Cloverleaf Infrastructure, explains how the AI boom has transformed data center power demand from a regional constraint to a systemic grid challenge, with some utility queues showing speculative 'zombie requests' masking tens of gigawatts of real load. He argues that efficiency gains will not curb growth because hyperscalers simply build larger, more powerful facilities when capacity allows, making decarbonization targets increasingly difficult to meet on original timelines. Janous details how data centers can mitigate grid impact by leveraging behind-the-meter assets like UPS batteries and generators to become dispatchable, as seen in Dublin, and by supporting grid-enhancing technologies to avoid long interconnection delays.
