Andreas Schierenbeck, Hitachi Energy’s CEO, says rapidly expanding data centers are creating new power-quality stresses while utilities confront transformer shortages, long permitting cycles and a broader security threat that spans physical attacks, cyber incidents and fragile supply chains.
Why AI is changing power-grid demand
AI data centers do not behave like ordinary commercial loads. Their graphics-processing units (GPUs) can start and stop in parallel, creating very short power bursts. Hitachi Energy’s leadership says those bursts can stress electrical systems inside a data center as well as the external grid that supplies it.

Schierenbeck describes the competition for AI capacity in blunt terms: “AI is a race for speed, which means a race for energy, and that’s what the US is having.” The implication is that a country’s ability to connect generation, transmission and distribution capacity quickly can become a competitive advantage.

Why transformers are taking years to obtain
Large power transformers are a critical bottleneck because they are highly engineered, heavy assets that require specialized factories, components, testing and transport. S&P Global Energy/Platts reported in 2026 that waiting times can reach up to 40 months.
Hitachi Energy says it has committed more than $9 billion globally to address shortages, including $1.5 billion for transformer production. It also says $6 billion of manufacturing-capacity expansion is planned by 2027. Those are company commitments, not a guarantee that every buyer will receive equipment within a particular schedule.
| Constraint or investment | Figure and qualification |
|---|---|
| Transformer lead time | Up to 40 months, reported by S&P Global Energy/Platts in 2026 |
| Hitachi Energy shortage-relief commitment | More than $9 billion globally, including $1.5 billion for transformers |
| Planned manufacturing expansion | $6 billion by 2027, according to Hitachi Energy |
| Company-estimated 2030 market | $350 billion for Hitachi Energy products, a company estimate reported in 2026 |
Buying more equipment is only part of the solution. Grid developers must forecast demand early, reserve factory capacity, secure transport and coordinate interconnection studies. If generation is built without transmission, or a data center receives a connection before substations and transformers are ready, the nominal capacity on paper does not translate into usable power.

Why Schierenbeck calls the grid a strategic asset
Schierenbeck says “the Electricity Era” is shifting energy systems from molecules to electrons. In his formulation, resilient electric networks now have the strategic importance that oil and gas pipelines once held.
Rank #2
That strategic role expands the meaning of energy security. The risks he identifies are:
- Physical attacks: damage to substations, lines, transformers or control facilities.
- Cyber threats: attempts to compromise operational technology, information technology or connected equipment.
- Supply-chain vulnerabilities: dependence on scarce components, concentrated manufacturing and difficult logistics.
- Targeted disruption: coordinated actions intended to interrupt a particular region, facility or service.
Security therefore cannot be treated as a firewall added after construction. Utilities need resilient designs, secure procurement, maintenance access, spare-parts strategies and operating procedures that still work when communications or equipment are degraded.
What AI can do in grid operations
Material from the Hitachi Research Institute describes utilities adopting AI in progressively more demanding roles:

- Prediction: detecting patterns associated with wear, abnormal behavior or impending failure.
- Real-time decision support: bringing live operational data into recommendations for control-room and field teams.
Generative and agentic AI can optimize discrete enterprise workflows, but utilities still need an AI-ready strategy across the operational-technology and information-technology stack. A model that produces a plausible recommendation is not automatically safe to use in a protection system or control room. Data quality, permissioning, human approval, auditability and fallback operation remain essential.
HMAX Energy: Hitachi Energy’s Plan, Predict and Prevent approach
Hitachi Energy launched HMAX Energy on March 23, 2026. The suite applies AI and digital models across transformers, switchgear, substations, high-voltage direct-current (HVDC) systems and power-quality equipment.
Plan
The Plan function provides asset-lifecycle and operational recommendations. Its purpose is to help owners decide where to invest, which assets need attention and how operating choices affect long-term reliability.
Predict
Predict monitors equipment for early signs of wear and unusual behavior. Earlier detection can turn an unexpected outage into a scheduled inspection or repair, but the quality of the result depends on sensor coverage, historical data and engineering validation.
Prevent
Prevent combines health checks, simulation and proactive intervention. Digital twins can represent equipment and operating conditions so teams can test responses before an incident occurs. Hitachi Energy cites IdentiQ digital-twin use for HVDC incident response.
Rank #4
| Reference-case outcome | Reported result | Attribution |
|---|---|---|
| Revenue loss from equipment breakdowns | Up to 60% lower | Hitachi Energy reference cases, 2026 |
| Transformer failures | 50% fewer through early detection | Hitachi Energy reference cases, 2026 |
| Repair costs | Up to 75% lower | Hitachi Energy reference cases, 2026 |
| HVDC incident-response time | Up to 90% faster with digital twins such as IdentiQ | Hitachi Energy reference cases, 2026 |
These percentages are vendor-reported reference-case figures, not a universal performance guarantee. Results can vary with asset age, monitoring hardware, network design, maintenance practice and the definition of a failure or response event.
Will data centers overload the grid?
Not automatically, but they can expose weaknesses that conventional planning did not have to model. The parallel GPU bursts add short-duration power-quality and ramping concerns, while the overall load adds a large, relatively concentrated demand block.
Managing the risk requires several layers:
- Model the data center’s internal electrical behavior, not only its average megawatt demand.
- Study transformer, switchgear, protection and substation limits under rapid changes.
- Build generation, transmission and distribution ahead of confirmed demand where policy and financing allow.
- Coordinate connection dates with equipment procurement and permitting milestones.
- Use monitoring and predictive maintenance to reduce the chance that one failed asset removes scarce capacity.
Schierenbeck contrasts the United States’ rapid data-center build-out with Europe’s greater regulatory and grid-connection uncertainty. The comparison is about delivery speed and system readiness, not a claim that one region has solved reliability.
Generation and storage choices
More generation alone will not eliminate congestion or intermittency. Schierenbeck supports locating green-hydrogen production and electrolyzers near renewable generation and pipelines. Batteries are advancing quickly, but he says longer-duration storage is still needed.
| Option | Role in the transition | Limitation or open question |
|---|---|---|
| Conventional grid equipment | Proven transformers, switchgear, substations and transmission assets provide the backbone for new connections. | Manufacturing and delivery can take years, with transformer waits reported up to 40 months. |
| Solid-state transformer concepts | Offer a potential path to more controllable power conversion and advanced monitoring. | The supplied public statements do not establish deployment scale, cost or readiness. |
| Batteries | Provide fast response and short- to medium-duration balancing. | Long-duration needs are not fully addressed by rapid battery progress alone. |
| Green hydrogen and electrolyzers | Can be colocated with renewable generation and pipelines and store energy in another form. | Projects require suitable renewable supply, pipelines and conversion infrastructure. |
| Digital twins | Simulate equipment and incidents, supporting planning and faster response. | Models must be kept current and connected to trustworthy operational data. |
What the scale of Hitachi Energy means
Hitachi Energy says it operates in more than 140 countries, has more than 50,000 employees across 60 countries and generates around $16 billion in revenue. Those company-profile figures indicate the scale at which it is pursuing manufacturing, service and digital-grid investments; they do not by themselves measure reliability improvements for a particular utility.
What to watch next
The central test is whether grid expansion can move at the speed of AI demand without weakening security. Watch for transformer and switchgear capacity coming online, transmission and interconnection approvals, data-center projects that disclose realistic load profiles, and utility AI deployments that show how human operators validate automated recommendations.
Schierenbeck’s argument is ultimately about timing: immediate AI load growth is meeting a 10–20-year infrastructure horizon. Treating electricity, equipment supply and security as one planning problem is the only way to prevent a fast software build-out from running into a slow, vulnerable power system.
