Sustainable power supply for grid operators and cable works

The electricity grid is being expanded at speed. Grid operators are running a growing number of projects simultaneously: new cable routes, transformer substations, connections and renovations of existing infrastructure. That work takes place at locations without a grid connection, in urban environments with strict emission requirements and under tight schedules that cannot tolerate downtime.

Volta Energy delivers the power supply needed for that. Clean, silent and fully managed.

The challenge for grid operators and their contractors

Cable works and grid expansions face a particular paradox: the contractor responsible for expanding the grid has no grid connection of their own. Work along cable routes, in rural areas, and at new sites requires a fully off-grid temporary power supply.

At the same time, grid operators are imposing increasingly strict sustainability requirements on their contractors in their own tenders. CO₂ reduction targets, emission-free working and noise standards in public spaces are not minor details but hard contractual requirements. A contractor working on the sustainability of the electricity grid can hardly justify running their own temporary power supply on conventional diesel.

On top of that, the number of projects is growing faster than available connection capacity due to grid congestion and the energy transition. Schedule pressure is high, locations are diverse and requirements are strict. The temporary power supply needs to be right from day one.

How does a Volta work on cable projects?

A Volta is a reliable 3-in-1 mobile energy system that combines solar panels, smart batteries and a biofuel backup in one system. During the day, the panels charge the battery. The battery delivers power to the installation on site, including at night and in overcast conditions. When capacity falls short, the backup kicks in automatically.

The system manages itself, is monitored remotely 24/7 and requires no manual actions on site. Our technicians deliver, install and verify operation. We take care of fuel management and maintenance. The contractor focuses on the work.

For which cable and network works is a Volta suitable?

Volta Energy supplies temporary power for a wide range of work for grid operators and their contractors. Common applications include site cabins and tools for cable excavation work along routes, temporary installations at new transformer and switching substations, power supply during the construction of new medium and low voltage cabinets, lighting and camera surveillance for work sites and storage locations, charging points for the contractor's electric equipment, and measurement equipment and security systems at remote work sites.

For all these applications: a Volta is ready to deploy without a grid connection, runs cleaner than diesel and is delivered fully managed.

Why grid operators and contractors choose Volta Energy

  • Ready to deploy along the route
    Cable works move along the route as the project progresses. A Volta is mobile and quick to relocate. We deliver at the new location, you carry on with the work.
  • Demonstrably lower emissions for tender requirements
    Our systems achieve an average of more than 90% less CO₂ compared to a conventional diesel generator. We make monitoring data available for use in project reporting and accountability to the grid operator as the commissioning party.
  • Silent in public spaces
    Cable works in residential areas, along busy roads or in urban environments require a silent energy solution. A Volta runs completely silently in standard operation. No complaints from local residents, no issues with noise standards.
  • Suitable for low-emission zones and nitrogen-sensitive areas
    Grid expansions also take place in and around Natura 2000 areas and low-emission zones. On models with a fuel cell as backup, the system is fully nitrogen-free and particulate-free. Ideal for the most emission-sensitive environments.
  • Centralised monitoring for multiple work sites
    Grid operators and large contractors work across multiple locations at once. We monitor all systems centrally and remotely. Consumption, battery status and system performance are visible in real time, per site. Issues are flagged and resolved immediately.

Energy-as-a-Service

Through our Energy-as-a-Service model, we take full care of energy management. Delivery and transport to site, installation and commissioning, fuel management and timely replenishment, maintenance and 24/7 remote monitoring are all included in a fixed, all-in-one price.

For contractors working for grid operators and managing multiple locations at once, that is a real advantage. No separate contracts per work site, no unexpected fuel invoices and no operational burden for the site manager. We monitor centrally. You work on the grid.

You build the grid of tomorrow. We supply the energy to do it.

The grid is growing. Emissions are falling. Volta Energy makes it possible.

Frequently Asked Questions about our solution for grid operators

  • How quickly can a Volta be deployed at a new work site?
    A Volta is typically operational within fifteen minutes of delivery. Get in touch with our team for current lead times and availability. For large projects with multiple sites, we coordinate the schedule together with you.
  • Can a Volta relocate as work progresses along a cable route?
    Yes. Our systems are mobile and quick to relocate. We handle the relocation, even when that is needed multiple times during a single project.
  • Does a Volta meet the sustainability requirements in grid operator tenders?
    Our systems achieve an average of more than 94% less CO₂ compared to a conventional diesel generator. We make emission data and monitoring reports available for use in tender documentation and project accountability to the grid operator as the commissioning party.
  • Is a Volta suitable for work in low-emission zones or Natura 2000 areas?
    Yes. On models with a fuel cell as backup, the system is fully nitrogen-free and particulate-free. Suitable for the most emission-sensitive environments, including areas with active nitrogen restrictions.
  • Does a Volta work for long-term projects lasting several months?
    Yes. Our systems are designed for long-term use. Fuel management and maintenance are fully included in our Energy-as-a-Service model for the full duration of the project.
  • How is the Volta monitored during network projects?
    Volta Energy monitors all systems 24/7, remotely, via its own monitoring platform. Consumption, battery status and system performance are visible in real time, per site. Deviations are flagged immediately and handled by our team, with no intervention required from the contractor on site.
  • Can I rent a Volta for multiple work sites at once?
    Yes. Volta Energy specifically serves contractors managing multiple locations at once. We monitor centrally, you manage the projects. One point of contact for all locations, regardless of the number.
  • Can a Volta be used for work at transformer and switching substations?
    Yes. A Volta delivers reliable power for site cabins, tools, measurement equipment and security systems at locations without a grid connection. We advise based on the power demand of your specific installation.
  • How does Volta Energy support CO₂ reporting to the grid operator?
    Through our monitoring platform, consumption data and emission reductions are visible in real time, per project and per site. We can provide project reports that can be used for accountability to the grid operator, in tenders or for internal ESG reporting.
  • Can Volta Energy also enter into framework agreements for multiple projects?
    Get in touch with our team to discuss the options for framework agreements and multi-year partnerships. We are glad to build a structural energy partnership with contractors who regularly work for grid operators.
