ENERGY & POWER
Data centres are under pressure to do more with the energy they consume. Higher-density workloads, tighter power constraints and the growing cost of inefficient cooling have made visibility an imperative reporting feature. Real-time energy monitoring gives operators the data needed to understand what is happening across electrical and thermal systems as it happens, then act before inefficiencies become faults or downtime.
The most useful deployments now combine monitoring with automation, predictive analytics and digital twin modelling. That shift is visible across energy infrastructure, compute load management and thermal optimisation, where operators are moving away from static checks and towards continuous operational awareness. The result is a more measured approach to power use, maintenance and capacity planning. But what does real-time energy monitoring look like in practice?
Here, Data Centre Magazine explores some of the latest and greatest innovations transforming power visibility for operators around the world.
Hitachi Energy: Comprehensive oversight Hitachi Energy’ s HMAX Energy launch shows how real-time monitoring is being applied to critical infrastructure beyond the data hall itself. The company says the AI-powered suite is designed to safeguard energy assets while improving operational efficiency, with a plan, predict and prevent model that uses data-driven insights, early asset monitoring and proactive maintenance.

COMPANY: HITACHI ENERGY INDUSTRY: ENERGY
Wolf Müller brings 30 years of energy sector leadership experience from ABB, Alstom and General Electric to Hitachi Energy. A mechanical engineering master’ s graduate, he serves on two external boards.
For data centre operators, the reliability of the facility depends on the wider electrical chain as much as on the IT load. Hitachi Energy’ s reference cases point to faster response times and earlier fault detection, with the company saying its approach can reduce revenue loss from equipment breakdowns by up to 60 % and transformer failures by 50 %. The HMAX model also uses digital twins to provide a real-time view of system status, lifecycle and performance, which is particularly important in environments where grid and asset conditions can change quickly.
Wolf Müller, Managing Director of BU Service at Hitachi Energy, says:“ Today’ s ageing grid is under unprecedented pressure and faces multiple challenges simultaneously, such as soaring energy demand, increasing complexity, supply chain constraints, and workforce shortages. With HMAX Energy, we are partnering with customers to safeguard critical infrastructure, anticipate failures earlier and keep electricity reliable.”
