Varun Sivaram is Founder and CEO of Emerald AI, a company building software that makes AI data centers power flexible. As AI data centers become one of the fastest-growing sources of electricity demand, grid constraints are emerging as a critical bottleneck for compute deployment.
In this episode, the conversation focuses on why power availability — not GPUs — is increasingly the limiting factor for AI. Data centers concentrate massive electrical loads in specific locations, creating grid stress, long interconnection delays, and rising electricity costs for surrounding communities. Traditional grid expansion alone is too slow to meet near-term AI demand.
Emerald AI’s response is to treat AI data centers as flexible loads rather than fixed ones. Its software coordinates compute with grid conditions by shifting workloads across time, geography, and on-site energy resources like batteries. The episode walks through real-world demonstrations, including a published field trial showing a 25% power reduction during grid stress without breaking compute performance. The discussion frames flexible load as one of the fastest ways to unlock power for AI while improving grid stability.
