Resonating Efficiency: The Role of Power Harmonics in AI Data Centers

Hyperscale and AI-focused data centers are pushing electrical infrastructure to new limits—yet one critical risk remains underestimated: power harmonics. This session sheds light on how non-linear loads from high-performance computing systems and large-scale cooling infrastructure contribute to harmonic distortion, creating hidden inefficiencies, equipment stress, and increased operational risk. The challenge becomes even more complex when these harmonics interact with on-site generation sources, such as gas turbines or backup gensets, potentially triggering resonance and performance instability across the facility.

While IEEE 519 and other standards have long served as best-practice guidance, a regulatory shift is on the horizon. Utilities are already experiencing transformer overheating, instability, and DER integration issues linked to harmonic pollution. Compliance with harmonic limits is expected to evolve from voluntary to mandatory. Forward-thinking operators and integrators must act now—understanding the risks, monitoring the metrics, and planning mitigation strategies—to stay ahead of rising expectations and avoid costly downtime or redesigns. This session offers the foundational awareness hyperscale players need to future-proof their infrastructure and protect uptime in a rapidly intensifying power environment.
