The AI Energy Economy — Part 3: Where the Grid Meets the Machine
The Connective and Last-Meter Layers of AI Electrification
Part 2 of this series focuses on the companies building the physical backbone of AI electrification: turbines, transformers, substations, transmission lines, grid-scale batteries, and the construction required to deploy them. These firms profit whenever utilities and hyperscalers invest in additional electrical capacity, regardless of which energy source ultimately produces the power.
But as AI demand scales, another reality becomes clear: electricity systems don’t just need more hardware — they need coherence.
Power must be generated, transmitted, conditioned, distributed, stabilized, and controlled at the same time. At AI scale, the seams between those layers become just as important as the layers themselves. A failure, bottleneck, or inefficiency at any one of these junctions can limit the usefulness of power everywhere else.
This section focuses on the companies that connect those layers — from grid-level infrastructure down to the point inside facilities where electricity must be safely delivered and heat must be continuously removed for AI systems to operate at all. This is the layer where the grid stops being an abstract system and starts becoming a physical constraint on computation.
1. What “Torque” Means in This Series
Throughout this series, torque is used as a metaphor borrowed from mechanics to describe how strongly a company’s earnings and stock price respond when AI drives electricity demand higher.
Low-torque businesses — such as regulated utilities — benefit steadily as demand grows, but their upside is constrained by regulation, rate cases, and long planning cycles. High-torque businesses sit closer to the system’s breaking points. When infrastructure becomes constrained or demand accelerates unexpectedly, their products become urgently needed, orders accelerate, and earnings can re-rate quickly.
In short: torque increases as you move closer to the constraint.
2. GE Vernova (GEV): The Bridge Company of AI Electrification
GE Vernova does not belong in just one part of this series because it does not operate at just one layer of the power system. It does not own power plants, and it does not sell electricity to end customers. Instead, it supplies the equipment, technology, and systems that allow electricity to be generated, moved, stabilized, and managed at scale.
In practical terms, GE Vernova builds much of the machinery that makes modern power systems function. Its businesses include gas turbines used for firm and fast-ramping power, nuclear reactor technology and services through GE Hitachi, grid equipment such as transformers and substations, high-voltage transmission components and power electronics, and software used to monitor and balance increasingly complex power flows. If electricity is being produced, transmitted, or stabilized somewhere in the system, GE Vernova is often involved.
For readers new to the sector, it can help to think of GE Vernova as a system integrator for electricity. Utilities and grid operators don’t just need more power — they need many different pieces of equipment to work together reliably under rising stress. GE Vernova sits at the junction where generation, transmission, and grid control intersect.
That positioning matters in the AI era. AI demand does not stress one isolated component of the grid. It increases load on generation, tightens transmission corridors, raises congestion risk, and requires more sophisticated control to keep voltage and frequency stable. GE Vernova benefits whenever utilities add new generation, expand transmission, upgrade substations, or invest in power electronics and software to manage instability. In other words, it benefits from system-wide stress, not from one specific technology winning.
Investment view
GE Vernova is no longer an under-the-radar name, and it is not cheap on a simple headline basis. However, its valuation looks more reasonable when viewed against three factors: a large and growing order backlog, improving margins following the GE restructuring, and unusually broad exposure across the entire power system rather than a single niche.
Unlike companies tied to one technology — such as only renewables, only nuclear, or only data centers — GE Vernova participates in nearly every major category of AI-driven grid investment. That breadth reduces dependence on any single policy outcome or energy source and increases the durability of earnings over a multi-year build-out cycle.
Bottom line:
GEV is a Buy as a cornerstone, system-wide electrification play. It may not offer the explosive torque of narrow bottleneck specialists, but its unmatched reach across generation, transmission, and grid intelligence makes it one of the most resilient beneficiaries of AI-driven electricity demand.
3. Prysmian Group (PRYMY): The Arteries of the AI Grid
Prysmian focuses on one deceptively simple task: moving electricity from where it is generated to where it is needed. It is the global leader in high-voltage and HVDC (high-voltage direct current) cabling — the specialized cables required for long-distance transmission, inter-regional grid connections, offshore wind, underground routes, and most large HVDC projects worldwide.
As AI data centers scale, electricity increasingly has to travel farther. Many reliable power sources — nuclear plants, large gas facilities, hydro, offshore wind — are not located next to dense compute hubs. In many cases, the binding constraint is no longer how much electricity can be generated, but whether it can physically reach the data center at all.
High-voltage transmission cables are not interchangeable commodities. They are capital-intensive, custom-engineered products designed for specific voltages, routes, and environments. Manufacturing capacity is limited, projects require years of planning and permitting, and installation — especially offshore or underground — is slow and complex. Once a transmission project is approved, cabling often becomes the pacing item that determines how fast power can be delivered.
Because of this, Prysmian enjoys unusually strong scarcity dynamics. Utilities cannot easily substitute another supplier at scale, and delays in cabling can stall entire multi-billion-dollar generation or data-center projects. That gives Prysmian pricing power, long-dated order backlogs, and strong revenue visibility.
Bottom line:
PRYMY is a Buy for exposure to grid-level physical constraints — a direct way to invest in the reality that moving power across regions is becoming just as scarce and valuable as generating it.
4. nVent Electric (NVT): Where Power Becomes Usable
As electricity volumes grow, so does the complexity of distributing and protecting power inside data centers, substations, and industrial facilities. That complexity is nVent’s opportunity.
nVent specializes in enclosures, busbars, power-distribution systems, grounding, and protection hardware — the systems that take high-voltage power arriving at a facility and make it usable inside the building. At AI scale, power density rises sharply, pushing far more electricity through smaller physical footprints and increasing heat, fault risk, and the cost of failure.
You cannot simply “plug in” a gigawatt-scale AI facility. Power must be stepped down, routed, contained, and protected as it moves toward racks running continuously. Without robust internal electrical infrastructure, power becomes unsafe or unreliable long before upstream generation or transmission limits are reached.
After divesting its thermal-management business, nVent is now a more focused electrical-infrastructure company, with infrastructure end markets accounting for more than 40% of revenue.
Bottom line:
NVT is a Buy — a quietly compounding AI-infrastructure play with direct exposure to last-meter electrical constraints, improving profitability, and a valuation that remains more reasonable than many higher-profile AI beneficiaries.
5. Vertiv (VRT): Keeping AI from Overheating
Vertiv specializes in cooling, thermal management, and power-conditioning systems for data centers. While electricity enables computation, heat ultimately limits it. Nearly all the power consumed by GPUs and accelerators is converted into heat, and AI workloads generate far more heat than traditional computing.
Modern AI racks often exceed the limits of conventional air-cooling designs, driving rapid adoption of liquid cooling, immersion cooling, and tightly integrated power-and-cooling architectures — areas where Vertiv is a core supplier.
Once power density crosses certain thresholds, cooling becomes a hard constraint. If heat cannot be removed fast enough, servers automatically throttle performance or shut down. At that point, upstream power availability becomes irrelevant.
Bottom line:
VRT is a Speculative Buy — a high-torque beneficiary of AI cooling constraints. Upside is meaningful if AI density continues to rise, but valuation leaves less room for error than more conservatively priced infrastructure names.
6. How nVent and Vertiv Fit Together
nVent governs whether power can safely enter and move through a facility. Vertiv governs whether that power can continue to be used once it turns into computation. One controls electrical survivability; the other controls thermal survivability.
As AI data centers push toward higher rack density, higher utilization, and tighter uptime requirements, both constraints bind at the same time. Failures at either point immediately limit usable compute — regardless of how much generation exists upstream.
This is why these companies operate at higher torque than broader electrification players. They sit where abstract grid capacity turns into real, usable computing power.
7. Amphenol (APH): The Final Connection Point
Amphenol designs the connectors and cabling systems that carry power and data between servers, GPUs, racks, cooling systems, and control electronics. These components may look small, but without them, nothing works.
As AI data centers grow denser, connections must tolerate higher loads, higher temperatures, and continuous operation. A single failed connection can shut down an entire rack or trigger cascading failures.
Amphenol sits at the final step of the electrification chain, ensuring that upstream investments in generation, transmission, distribution, and cooling actually reach the chips doing the work.
Bottom line:
APH is a Hold — a high-quality, long-term compounder with AI exposure, but lower torque and less valuation-driven upside than last-meter electrical and cooling specialists.
8. Conclusion: Connection Is Value
AI does not strain one part of the electricity system in isolation. It stresses the entire system at once — exposing weaknesses at the points where generation, transmission, distribution, and computing meet.
GE Vernova connects systems. Prysmian connects regions. nVent connects facilities. Vertiv keeps them operable. Amphenol connects components.
Together, they operate in the layers where electricity stops being an abstract commodity and starts determining whether AI infrastructure can function at all.
In an AI-driven energy system, connection is value — and these companies sit squarely at that intersection.
Part 4 examines how these increasingly stressed systems are kept stable through automation, controls, and real-time intelligence.
