AI compute is ready years before the grid is.
Picture the customer's seat: an operator with land, capital and GPUs on order — and a high-voltage connection date somewhere in the 2030s.
Power — not chips, not land — is the binding constraint on AI build-out.
A behind-the-meter power island, delivered.
Partners deliver the megawatts. Our layer makes them GPU-grade — a two-tier battery bank and one supervisory controller, designed in from day one.
The megawatts
Proven turbine projects through established energy partners — capacity that arrives on a truck, not on a ten-year transmission plan. We don't build it. We firm it.
Two-tier battery
Our architecture: energy banked and released the instant GPUs spike, absorbing the transients generation alone can't follow — so the load sees steady, GPU-grade power.
One plant controller
Our supervisory software runs generation and battery as one plant — dispatch, buffering and islanding handled together, not bolted across vendors.
No. We don't sell storage capacity into energy markets — and we don't sell power. We sell firmness: the battery architecture and control software that make a power island GPU-grade.
We don't sell electrons. We make them firm.
Not a battery manufacturer. Not a power utility. Battery Vault designs the firming layer — the vault and the plant controller — delivered inside power-island projects led by established energy partners.
Tell us your load. We'll do the rest.
Move the slider — the firming layer scales with your campus, the timeline doesn't.

AI power is going behind the meter — at gigawatt scale.
Grid connections take years AI operators don't have. So generation is moving on-site — turbines, engines, microgrids — and a new asset class is being built at speed.
The operators with capital are no longer waiting for the utility. They're signing for on-site power today — and every one of those projects needs a firming layer to make it GPU-grade. That layer is what we sell. The window is open now.
The only option that's fast, firm and clean.
On-site megawatts arrive in months. Whether they're GPU-grade is decided by the firming layer.
Why we can deliver Our layer ships inside projects delivered by established energy partners running field-proven turbine plant — real projects, not slideware. Partner detail under NDA.
Every AI power island needs firming. That layer is ours.▍
Whether you build islands, run GPUs, or back the people who do — let's talk about making on-site power GPU-grade.
