The firming layer · behind the meter

On-site power, made GPU-grade.

Turbines can reach an AI campus in months — but turbines alone can't follow GPU transients. Battery Vault is the layer that makes that power firm: a two-tier battery bank and one plant controller, designed into partner-delivered power islands.

Generation runs steady. GPUs spike. The Vault banks the difference — that difference is the layer we build.
The constraint

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.

The solution

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.

01 · Generation — partner-delivered

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.

02 · The Vault — ours

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.

03 · Control — ours

One plant controller

Our supervisory software runs generation and battery as one plant — dispatch, buffering and islanding handled together, not bolted across vendors.

“Another BESS startup?”

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.

What we are

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.

Why now

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.

5+ GW
Behind-the-meter generation announced by a single US provider since 2024 — the wave is already here.
110 MW
Europe's first data-centre microgrid of this kind is already live — the model is proven, the market is forming.
Where we win

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.
