ENERGY & POWER
A system-wide visibility gap This visibility gap is systemic. Similar blind spots can be found across the data centre. Cooling and HVAC systems now require real-time thermal mapping and correlation of electrical losses to heat generation. Energy losses compound across the power delivery chain. From high-voltage transmission through multiple transformation stages down to low-voltage rack-level supply, each step introduces inefficiencies that quickly add up.
Even energy cost-management strategies are affected. On-site generation and battery arbitrage, time-of-use pricing and grid-interactive
UPS systems are all designed to optimise cost and resilience. But they rely on accurate, dynamic measurement to function effectively. Without it, operators struggle to determine when to charge or discharge batteries, to leverage generators or whether they are delivering the intended value.
“ AI workloads don’ t just draw power; they strain everything downstream of it, from thermal management to structural load,” adds Kees.“ The real challenge is connecting what’ s happening electrically to how the rest of the system responds. That’ s the visibility most operators are still missing.”
