For construction sites without a grid connection

You want a fossil-free construction site; that's possible today, even without a grid connection.

The Powerbox feeds the biogas generator on your site: renewable gas, mobile delivery, without a grid connection. The diesel goes, the generator stays. With the evidence your client wants to see, per delivery.

How your delivery works

From diesel to biogas in four steps.

Set up once, then repeatable per project: the same route and the same evidence file on every construction site.

STEP 01

Power and duration

You enter your consumption per hour, running hours, duration and postcode. The price indicator returns a range and the number of Powerboxes.

INPUTkWh · hours · weeks

STEP 02

Powerbox in place

The unit stands on level ground next to the biogas generator and supplies the gas; the generator turns it into power.

STEP 03

Swap during the work

Full units come in, empty ones go out, planned around your consumption. If the project runs on, the swaps run on with it; every swap is logged.

STEP 04

Evidence file for the client

One report per project: the origin of the gas, the delivery log and metered consumption.

What you pay and why

What determines the price?

Biogas on a construction site has a price that follows from what you choose. The price indicator shows that range before you talk to anyone.

What determines the range

  • The power you need and the running hours per day and per week.
  • The duration of the project in weeks.
  • Whether you need a generator or already have one.
  • The transport distance, based on your postcode.

What you get back

  • A range per week and over the term, next to HVO and next to doing nothing.
  • The substantiation per line item and the CO2 comparison.
  • A route brief you share with your client.
  • "Price on request" if the indicator can't give a figure; then we work it out for you.

What your client can check

A fossil-free construction site only becomes an award criterion if you can show it afterwards. Per delivery we log:

Frequently asked questions

What builders ask us first.

How much space does a Powerbox take up on the construction site?

Comparable in size to a generator set; the Powerbox stands beside it. The unit sits on level ground; the exact footprint depends on the type and follows from the price indicator and the intake meeting.

What happens if the project runs over or consumption peaks?

The swap scales with you: more swaps when consumption rises, longer deployment when the work overruns. Every swap is logged, so the evidence file stays correct, even when the schedule doesn't.

What proof can I show my client?

One report per project: the origin of the gas, the delivery log and metered consumption, supplied with the invoice. See the proof.

Does this also work on sites with no connection at all?

Yes. The chain is built for places where the grid falls short or arrives too late: construction sites, infrastructure projects and temporary locations. If your site does have a good connection and the work can run on electricity, the scan will say so too.

First step

Calculate your price indication.

Power, running hours, duration and postcode. You'll get a range back, alongside HVO and alongside doing nothing, plus a route brief to share.
