Xalant Power
Off-grid power, in the right order.
A phased, off-grid energy stack, built in the order the lead times allow rather than the order a pitch deck would prefer.
Bridge generation first, because it can be standing in months. Enhanced geothermal next, because deep heat is continuous and the drilling takes years. A fluoride-salt reactor last, and only once its cost model has been proven against the bridge. Every site is designed so that nothing on it waits for the rung above it.

Power · The ladder
Three rungs, one duration axis
Three rungs. One direction.
Each rung is sized so the campus never waits on the next one. The bridge opens a site in months; geothermal firms it over years; the reactor is a prospect for the decade after that, and is dimensioned nowhere until a regulator and a vendor have both said so in public.
- Months to first power
- Years to firm power

Bridge
Phase 1 · First rungBridge generation
Engines that burn a fuel you can bring in by road — liquefied petroleum gas at first, blended toward hydrogen as supply allows. They are ordered, shipped and commissioned in months, which is the whole reason they go first.

Geothermal
Phase 2 · FirmEnhanced geothermal
Heat that is already under the ground. Wells are drilled into hot, dry rock, water is circulated through the fractures between them, and what comes back up drives a turbine. Nothing is burnt and nothing arrives by road.

Phase 3 · No dateFluoride-salt SMR
A small reactor cooled by molten fluoride salt at close to atmospheric pressure, fuelled by ceramic-coated pebbles rather than metal-clad rods.

Power · Roadmap
How a site actually arrives
The order on the ground.
Five steps, in sequence, with the overlaps that make the sequence affordable.
- Step one
Land, load and a fence line
A site is chosen for what it can host rather than for what a utility can spare: room for the plant, land set aside for a reactor pad that may never be used, and a load worth building for.
- Step two
Bridge generation stands up
Gen-sets, switchgear, solar and storage arrive as one package, on the same timescale as the buildings around them. This is the point at which the site has power and the racks can go in.
- Step three
The wells go down
Drilling, stimulation and flow testing happen while the site is already carrying its load.
- Step four
Geothermal takes the load
The surface plant comes on and the bridge steps back to standby. Nothing is decommissioned and nothing is stranded — the site simply stops burning fuel to stay up.
- Later
The parcel that was reserved
The land held back in step one is where a reactor could go, Reserving it costs an acreage decision on the first drawing. Not reserving it costs the option outright.
Power · Why this order
Why this order
Bridge first, because a campus that waits for a reactor never opens.
Every energy technology on this page can carry a data centre. What separates them is not whether they work — it is how long it takes to get one standing, and what a site does in the meantime.
Gen-sets are the fastest thing that makes firm power. They are ordered from a catalogue, they arrive on trucks, and they are commissioned on the same timescale as the buildings around them. That is the entire argument for putting them first: the racks earn from the first month rather than from the first drilling season.
Enhanced geothermal is second because it is continuous, renewable and small on the surface — and because almost all of its work is underground, where nothing can be accelerated by ordering earlier. Wells are drilled, the rock between them is stimulated, the flow path is tested, and each step tells you whether the next is worth taking. A site that waited for that sequence before opening would be waiting for years with nothing running. A site that is already carrying load can afford to wait, which is the whole trick.
The reactor comes last, and the reason is regulatory and commercial rather than physical. A fluoride-salt reactor needs a licence, a vendor and a cost model proven against the rung it is replacing.
Read the order backwards and it stops making sense; read it forwards and each rung buys the time for the one above it. That is the whole design.
Bridge
Gen-sets, switchgear, solar and storage, specified as one package and ordered from a catalogue.
Firm
Wells drilled, stimulated and flow-tested while the site is already carrying its load.
Reserved
The parcel held back on the first drawing, a switchgear bus that does not care what feeds it, and a licence in front of it.
Power · Why off-grid
Why off-grid · the queue
The grid is a queue. Off-grid means not standing in it.
A generator that is not connected to a public network does not need permission from one. That single fact is what moves a site's schedule from a utility's study cycle to its own procurement cycle.

Power · Storage
Storage · three jobs
Store what the bridge makes.
Storage is what turns a yard full of gen-sets into a microgrid. A battery does three jobs on an off-grid site, and none of them is the one people expect.
Chemistry, capacity and supplier are design decisions that have not been made, so they are not stated here. What is settled is the role: storage is specified alongside the first gen-sets, not added after them, because a microgrid designed around a battery and a microgrid with a battery bolted on are different machines.

Watch the bridge back off.
Set the load and your own lead-time assumptions. The model shows what is carrying the site at every point, and what happens to the bridge when something firmer arrives. No costs, no calendar, and no figures that did not come from you.

Emissions intensity is not drawn yet. The curve is a weighted mean of each rung’s operating intensity, weighted by the load it is carrying that month — the arithmetic is done and documented. What is missing is the two published emission factors it multiplies, which ship with their source URL and the date they were fetched or they do not ship at all. A plausible-looking curve drawn from remembered figures would be worse than no curve.

The third rung is not on this chart. A fluoride-salt reactor is a next-decade prospect with a licence in front of it, and the only licensing duration in the source material comes from a private document rather than from the regulator — so it is named here and dimensioned nowhere. The maths behind everything above is written out in docs/tools/bridge.md.
Power · The stack
Four technologies, three rungs
Four technologies, one switchgear.
Every rung is designed to land on the same bus. The racks are never meant to know which technology is carrying them — only the fuel and the drawing change.
