Grid modernization & data-center power
Who supplies the power, the equipment and the fuel for the next decade of load growth.
Brief:
Electricity demand from data centers and electrification is growing faster than the grid was built for. The theme covers who supplies the equipment, who generates the power and who holds the fuel.

Scope
In scope: the listed companies that make grid and data-center electrical equipment, that own or develop the generation sold to large loads, and that supply the fuel for the nuclear part of it. Out of scope: the hyperscalers themselves and the semiconductor supply chain, which are other themes.
The space
Electricity demand is growing again after a long flat period, and the growth is concentrated in a small number of very large loads. The system was not built for that shape of demand: transformers, switchgear and interconnection queues are the bottleneck, and firm capacity close to the load is scarce. The companies that make the equipment report multi-year backlogs; the owners of firm generation are signing long-dated contracts; the fuel and small-reactor names are the speculative end of the same chain.
Why now
Backlogs and contract disclosure make the theme measurable now rather than a story. The equipment makers report orders and backlog every quarter, and the generation owners disclose the contracts they sign, so the thesis can be checked against reported numbers rather than forecasts.
Timeline
The constraint moved from generation to the grid over the last three years; the equipment backlogs built up first, the large-load power contracts followed, and the nuclear-fuel and small-reactor links are the latest and least certain part of the chain.
How it works
A large load needs firm capacity, a grid connection and the electrical equipment to take the power from the substation to the racks. Each of those is supplied by a different set of companies, and each has its own lead time. The equipment is ordered first, the connection and the supply contract follow, and the plant is built around them.
How we got here
Demand was flat for roughly a decade, so the equipment makers and the utilities planned for replacement rather than growth. When large loads arrived the lead times for transformers and switchgear lengthened, interconnection queues grew, and owners of existing firm generation found they held a scarce asset.
Where it stands today
Equipment backlogs are at multi-year highs and still growing; the first wave of large-load supply contracts has been signed and disclosed; the small-reactor developers have licensing milestones but no operating plants.
The open arguments
- Whether the equipment backlog is a one-time catch-up or the start of a longer cycle.
- How much of the large-load demand will be met by on-site generation rather than the grid.
- Whether regulators will allow direct contracting between generators and large customers at scale.
Value chain
Each link was searched separately for public companies — which is what
surfaces the suppliers a single query omits.
Transmission & grid equipment
Transformers, switchgear and substation equipment; the longest lead times in the chain.
Pricing power while lead times stay long; capacity additions are the thing to watch.
Power electronics & distribution
The electrical distribution and power-quality equipment inside the facility.
Higher-margin, faster-growing; the most direct listed exposure to the fit-out.
Generation & capacity
Owners of firm, carbon-free or gas-fired generation that can sign long-dated supply agreements.
Contract pricing versus merchant exposure decides the quality of the earnings.
Data-center electrical fit-out
Backup generation, controls and building systems inside the data center.
Often a segment inside a larger industrial; dilution is the issue.
Fuel & nuclear supply
Uranium producers and the small-reactor developers.
Producers have contracts and cash flow; developers have licences and no revenue.
The names
Tier and role rank each name within this theme — they are not

| Duke Energy Corporation (Holdin | Generation & capacity | diversified | even | $89.7B | US listed | HELD |
A large regulated utility with load growth in its service territories; the theme is expressed slowly, through rate cases.
DifferentThe slowest-moving expression of the theme on the list.
BasisLoad-growth forecasts are published, but the rate-case timetable decides when they reach earnings.
Works ifRate cases approve the capital programme without lowering allowed returns.
Fails ifRegulators push back on the pace of spending.

| Honeywell International Inc. | Data-center electrical fit-out | diversified | even | $64.9B | US listed | HELD |
Building-automation and controls with some data-center exposure inside a diversified industrial.
DifferentThe exposure is too small a part of the whole to carry the theme.
BasisThe relevant segment is reported but is a small share of revenue.
Works ifThe building-technologies segment outgrows the rest of the portfolio.
Fails ifThe segment stays a rounding error in the group's numbers.

| Oklo Inc. | Fuel & nuclear supply | speculative | long shot | $6.4B | US listed | pipeline |
An early-stage reactor developer; interesting for the theme's long tail, not for its current revenue.
DifferentA different reactor design from the other developer on the list; the same pre-revenue profile.
BasisPre-revenue; licensing milestones are the only observable progress.
Works ifLicensing and a first customer agreement arrive on the stated timetable.
Fails ifLicensing slips, and the capital raised runs out before a first deployment.

|
| NuScale Power Corporation | Fuel & nuclear supply | speculative | long shot | $3.0B | US listed | pipeline |
A small-reactor developer with design approvals but no operating plants; the theme's most speculative link.
DifferentPre-revenue; the case rests on orders that have not been placed yet.
BasisNo commercial deployment yet, so the odds rest on licensing and customer commitments still to come.
Works ifA first commercial order is placed and financed.
Fails ifCustomers wait for a competing design, and the funding window closes.

How we would play it
The desk's read is that the equipment link is the most direct expression and the one with the clearest reported numbers; generation gives the exposure through contracted capacity with a merchant tail; the fuel and reactor names are small, speculative satellites at most. This is a description of where the exposure sits, not a sizing instruction.
What must be true
- Large-load demand keeps arriving at the pace the utilities' own forecasts describe.
- Equipment lead times stay long enough to hold pricing while capacity is added.
- Regulators allow the capital programmes and the direct supply contracts the theme depends on.
What would kill it
- A pause in data-center capex that lets backlogs normalise within a year.
- A regulatory decision that blocks direct contracting between generators and large loads.
- A technology shift that sharply lowers the power needed per unit of compute.
What to watch
- Quarterly orders and backlog at the equipment makers.
- New large-load supply agreements and their disclosed terms.
- Interconnection-queue reforms and transformer lead times.
- Licensing milestones at the small-reactor developers.
