The hidden price tag of data center reliability

What if five minutes could cost you millions? In the world of data centers, that’s not hypothetical - it’s reality. 

Power reliability isn’t just a technical detail; it’s the invisible force that keeps businesses alive, apps running, and reputations intact. One blink, one outage, and everything can change. 

In this Q&A, we cut through the noise and get real about why reliability and resilience aren’t optional—they’re mission critical. Let’s dive in.

When it comes to data center reliability, we’re not just tossing around buzzwords—we’re referring to a measurable, mission-critical standard that truly defines success. Achieving 99.999% availability¹ means less than five minutes of downtime per year, setting an exceptionally high bar for the industry. This expectation highlights the importance of always staying online.

Power reliability forms the backbone of data centers, which serve as the digital heartbeats of our world. They keep businesses operational, apps available, and critical data secure. A single power blink can lead to lost transactions, dissatisfied customers, and millions of dollars in losses.

The data center industry is expanding at unprecedented speed, due to cloud computing, AI, and digital services. The rapid growth is straining local power networks², driven by a mismatch between the pace of data center construction and slow build out of grids and generation capacity (IEA). As a result, system complexity and aging infrastructure continue to challenge reliability, demanding constant vigilance and sustained innovation to maintain the highest operational standards.

Hitachi Energy’s understanding of data center operations is rooted in decades of practical, hands-on experience as the original equipment manufacturer (OEM) for leading energy technology. This background ensures that our expertise goes beyond theory, offering proven solutions in the field.

Our dedicated service teams have consistently supported mission-critical infrastructure in some of the most demanding environments. This has provided us with an in-depth knowledge of both the technology that powers data centers and the significant consequences associated with operational risks.

Hitachi Energy has global expertise and a strong local presence. Our specialists have witnessed the impact of escalating digital demands on power systems, recognizing that even a brief period of downtime can have catastrophic effects. Drawing from extensive experience, our teams ensure that every infrastructure receives exceptional care and maintenance, safeguarding uptime and reliability for our clients. 

Energy systems are critical from the day they’re powered up, and for data centers reliability is mission critical. That’s why maintenance and lifecycle services are not just about preventing breakdowns — they are about reducing every kind of disruption. Monitoring and predictive maintenance underpinned by strong partnerships deliver the insights needed to protect uptime, support timely decision‑making, and ensure your infrastructure can scale as demand continues to escalate.

Simple: We combine domain expertise with digital intelligence and service capabilities to catch issues before they happen, rapid emergency response when the unexpected hits, and modernization strategies to keep you future-ready.

Service is a craft refined over years and years by professionals who have spent their careers mastering energy systems. To address the evolving needs, Hitachi Energy strengthened its service capabilities and portfolio by establishing a new Service Business and announced investments of more than $1 billion USD worldwide. This is a commitment. A commitment to faster response times, deeper expertise, and solutions that combine human insight with cutting-edge technology. 

Our goal? Lower risk, improve efficiency, and keep your data center running without compromise.  Above all, we put safety at the forefront. This is the foundation of HMAX Energy, reliability empowered by digitally enabled service partnerships and delivering the outcomes needed for mission critical energy infrastructure.
