Artificial intelligence is redefining data center requirements and putting traditional electrical architectures to the test. With GPU workloads becoming increasingly dynamic, resilience is no longer measured solely by installed power capacity, but by the actual performance of the system as a whole. During this session, Pierre-Adrien Bel will present how a comprehensive approach to the design, modeling, and validation of electrical infrastructure can meet the needs of AI applications. Drawing on the latest studies from Rehlko and the e-POD solution, he will demonstrate how to reduce risks, strengthen resilience, and ensure predictable performance at scale.
