Reliable, sustainable energy for every construction project

The construction and infrastructure industry faces a dual challenge: delivering projects on time and within budget while meeting tightening demands on emissions, noise, and sustainability. Zero emission construction is no longer a goal. It is becoming an obligation.

Grid congestion makes a fixed connection impossible or impractical on a growing number of sites. Clients, municipalities, and regulators are raising the bar on emissions and noise. The sector needs an energy solution that simply works, without diesel and without hassle. That is what Volta Energy delivers.

Remote monitoring

All systems are monitored remotely. Issues are identified and resolved, most of the time before they affect progress. No on-site engineer required.

The challenge in construction and infrastructure

A construction site or an infrastructure project without a grid connection is the norm, not the exception. From the moment the ground is broken to final handover, power is needed for site offices, electric equipment, charging points, lighting, camera security, and measurement instruments. And that power must always be available, regardless of project planning.

The standard solution is still, too often, a conventional diesel generator. That works, but increasingly less well. Municipalities impose stricter requirements on emissions and noise in urban areas. Clients write CO2 targets into public tenders. Nitrogen restrictions delay projects or limit the use of polluting equipment. On top of that, fuel costs are rising and ESG reporting requirements are intensifying.

The construction and infrastructure industry wants to become more sustainable, but day-to-day execution pressure leaves little room for experimentation. The energy solution must be reliable, fast to deploy, and demand as little attention as possible from the site manager. That is exactly what a Volta delivers.

Our solution

A Volta is a reliable 3-in-1 mobile energy system: solar panels as the primary source, smart batteries for storage, and a biofuel backup that automatically activates when demand exceeds generation. The system manages itself, without manual intervention and without anyone needing to be on site.

For construction sites and infrastructure projects, that means an energy solution that is deployable immediately without a grid connection, scalable from a single site office to a full container park, and reliable under all weather conditions. From site offices and charging points for electric material and hand tools to heavy infrastructure projects with high power demand: Volta Energy has a model for every situation.

The first generation Volta, with HVO100 as backup, achieves on average more than 94% CO2 reduction compared to conventional diesel generators and is ready to deploy on any construction site. The Volta ZERO series, with a methanol fuel cell, is completely free of nitrogen oxides and particulate matter, and near-silent in operation. Ideal for urban construction projects, sites within low-emission zones, or projects subject to nitrogen restrictions.

Energy as a Service

Volta Energy does not just supply hardware. Through our Energy as a Service model, we take complete responsibility for energy management. Delivery, installation, fuel management, maintenance, and remote monitoring are all included in a fixed, all-in-one price.

For construction companies running multiple projects simultaneously, that is a meaningful advantage: no separate contracts per location, no unexpected fuel or maintenance invoices, and no operational burden for the site manager. We monitor everything centrally. The site manager or project manager can focus on what is important: managing the project.

You run the project. We manage the energy.

Frequently Asked Questions about our solution for construction & infrastructure

  • What is a Volta energy solution?
    A Volta is a realiable 3-in-1 mobile energy system that combines solar panels, smart batteries and a biofuel back-up into one self-managing power source. It delivers continuous power without a grid connection and without anyone needing to intervene on site. Solar is the primary source, the batteries absorb peak demand, and the back-up switches in automatically whenever it's needed.
  • Can I power a construction site without a grid connection?
    Yes. A Volta is fully deployable off-grid, replacing the grid connection on sites where one isn't available, is too expensive, or takes too long to arrange. That makes it suitable for the growing number of construction sites facing grid congestion or long connection lead times from the network operator.
  • How quickly is a Volta operational on site?
    A Volta is operational within an hour of arriving on site. There's no excavation, no connection procedure and no waiting period like there is with a grid connection, which makes it suitable for projects where the start date can't slip.
  • How much CO2 do you save with a Volta compared to a diesel generator?
    The first generation Volta, with HVO100 as back-up, achieves on average more than 90% less CO2 than a conventional diesel generator. The Volta ZERO series, with a methanol fuel cell as back-up, is also completely free of nitrogen and particulate emissions. The exact percentage varies by model and is calculated per project.
  • Does a Volta still supply power on cloudy days or at night?
    Yes. Solar is the primary source, but the smart batteries and biofuel back-up keep power flowing regardless of weather or time of day, so your construction site never stalls for lack of sun.
  • Who handles maintenance and monitoring of a Volta?
    Volta Energy monitors every system remotely and flags faults often before they can delay progress on site. Maintenance, fuel management and monitoring are all part of the Energy as a Service model, so you don't need anyone on location to keep the system running.
  • Is a Volta suitable for multiple projects or large-scale infrastructure work?
    Yes. The range scales from a single site cabin to a full compound or a large-scale infrastructure project with high power demand. Construction companies running multiple projects at once don't need separate contracts per location, since monitoring and management are handled centrally.
  • What's the difference between the first generation Volta and the Volta ZERO?
    The first generation Volta runs on HVO100 as back-up and can be deployed on any construction site straight away. The Volta ZERO uses a fuel cell, making it completely free of nitrogen and particulate emissions and virtually silent, which is why it's often chosen for urban projects or sites with nitrogen restrictions.
  • What does a Volta cost, and how is the price structured?
    A Volta is delivered through the Energy as a Service model: a fixed, all-in-one price covering delivery, installation, fuel management, maintenance and monitoring. There are no separate bills for fuel or breakdowns afterwards. The exact price depends on the model and project duration; we're happy to work that out with you.
