Compute Flexibility

Compute flexes. The host stays on.

Flexibility-as-a-Service — paid on stand-by, paid on activation and paid while Compute is running.

Use cases

At generation. In industry.

The host stays on. Compute is the load that can move.

  1. Hydro

    Hydro, geothermal, solar & wind

    Fully renewable generation. Compute behind the meter absorbs spill. Curtailment in full on Energy.

    The host keeps generating.

  2. Industrial & Manufacturing

    Industry cannot pause.

    Sawmills, pulp, drying, kilns. Unused connection becomes interruptible Compute.

    Checkpoint and resume, not a plant shutdown. Heat follows the load — Thermal.

  3. Spare

    Spare connection

    A connection that would sit idle — including beside a battery — becomes a load that earns Compute between calls.

    See Compute vs Battery Flexibility.

  4. Operator

    Compute operator

    Kelvin runs Flexbox, controller, meters and Compute. Flexibility-as-a-Service.

    See the service and Compute.

  5. Share

    The connection.

    Compute, grid services, Thermal/Heat and mitigation share the connection.

    No single stream has to carry the site.

Fully renewable at generation. Reliable because Compute flexes — not because the host pauses.

The service

You keep the plant. Kelvin runs Compute & Flexibility-as-a-Service.

Every large load needs this. Almost none of them can build it.

Industrial host — load in industry
  1. 01

    You keep operations

    Core operations stay yours. Unused connection capacity can be the interruptible megawatt.

  2. 02

    Flexbox, controller, meters

    Hardware, software, infrastructure — with the Compute.

  3. 03

    Not a bid screen

    Kelvin brings the load. Grid signal → the load moves in <0.7 s → the host stays on.

  4. 04

    A clear event log

    Pocket first, then metering and a clear event log. Curtailment at generation is on Energy.

How it pays

Stand-by. Activation. Compute running.

Compute Flexibility is the product. At high prices the load curtails and the reserve is sold — the spike becomes revenue.

  1. 01

    Stand-by

    Availability payments. The unit is ready to move.

  2. 02

    Activation

    Paid when the load moves. Dispatch <0.7 s. Activation just pauses Compute — no cycle penalty.

  3. 03

    While Compute is running

    The baseline whenever the unit is running. Compute keeps earning whenever the grid doesn’t call.

Signal in. Settlement out.

One service from the pocket to settlement.

Qualification, signal, dispatch, metering. System operators pay a premium for fast, controllable load. Built for grid-connected or co-located pads — LV or MV, behind the meter.

vs Battery Flexibility

Batteries store Energy. Compute earns while it flexes.

Multiple revenues, continuous dispatch, no cycle wear.

Compute Flexibility compared with Battery Flexibility (BESS). Compute wins on every row.

Compute Flexibility

Earns while it flexes

Upfront
Near-zero marginal cost — servers already deployed
Cycle
Zero — servers dispatch without wearing out
Duration
Unlimited — servers run continuously, around the clock
Recovery
None — assets available immediately after each dispatch
Risk
No chemical storage, no associated hazards
Revenue
Compute + grid services + Thermal/Heat, running simultaneously

Battery Flexibility

Stores Energy

Upfront
€200–500k per MWh of capacity (indicative)
Cycle
Capacity reduces with every activation
Duration
Fixed Energy reservoir; duration is capped
Recovery
Downtime required between activations
Risk
Fire and thermal-runaway risk with chemical storage
Revenue
Grid services only

Compute wins on every row.

Optional: Compute on a battery’s existing connection. Both qualify independently; adding a Flexbox does not reduce the battery’s available reserve. Fewer battery cycles. See Energy.

Markets

Built for the Nordic Energy Markets.

Restoration products follow on the same interruptible load.

Faster containment (FFR) is the same sub-second class the unit is built for.

FCR-D — frequency containment.

Why it holds

It’s a Compute Flexibility problem — not a wire problem.

Surplus is switched off because the load cannot move. Heat rides along.

  1. 01

    Milliseconds, not minutes

    Frequency needs a response in milliseconds. Interruptible Compute sheds on firmware signal — first off, first on. The Flexbox is built to move in <0.7 s.

  2. 02

    A pre-tested unit

    On-site controller and industrial-grade smart meters delivered as a single, pre-tested unit with the Compute. Kelvin software: control · dispatch · monitoring.

  3. 03

    The cheapest megawatt to switch off

    Interruptible Compute is the load that can switch off. Batch pauses at a checkpoint. The host never notices. See Compute.

The fleet

Not a building — a control system

Aggregated sites dispatch as one.

Transmission is a multi-year build; a coordinated fleet dispatches in seconds. Built to integrate with grid operators. Market to machine: control, dispatch, monitoring.
