Emergency power generator

Looking for an emergency power generator for locations without a grid connection? You're in the right place. But let's be honest: what we deliver goes beyond emergency power. A Volta is a solar-powered 3-in-1 mobile energy system that supplies reliable energy day in, day out. Not as a safety net, but as the primary power source on-site for any project and in any location.

What is an emergency power generator?

An emergency power generator is a backup power source that steps in the moment regular power fails, or simply isn't available. Think of construction sites, infrastructure projects, or telecom locations without a grid connection. In those situations, you need a reliable, mobile energy system that just works, every time.

Why not a diesel generator?

A conventional diesel generator is the familiar answer here, but it comes with real downsides: high fuel costs, heavy emissions, noise nuisance, and constant refuelling. Volta Energy offers a better and more sustainable alternative.

The Volta: more than emergency power

Volta Energy can offer a reliable 3-in-1 mobile energy system for every project and every power range, from a compact, low-power solution for mobile camera security or a traffic control system, to a powerful energy solution for a large construction site or infrastructure project. We will work with you to find the right model for your specific situation and power requirements.

Benefits over a conventional diesel generator

  • Significantly less emissions: on average 94% less CO₂ than a diesel generator.
  • Quiet by design: no noise nuisance for the surrounding area.
  • No nitrogen or particulate emissions on models with a fuel cell backup.
  • Continuous remote monitoring: we flag issues before you notice them.
  • Fully managed through Energy-as-a-Service: delivery, fuel management, maintenance, and monitoring all included.

Frequently Asked Questions about emergency power generators

  • What is an emergency power generator?
    An emergency power generator is a backup power source that activates when regular grid power fails or isn't available, commonly used on construction sites, infrastructure projects, and telecom locations.
  • Is the Volta only for emergencies, or can it run as a primary power source?
    The Volta is built to run as a primary, continuous power source, not just a backup. It combines solar, battery, and a clean fuel backup to deliver reliable power daily, wherever there's no grid connection.
  • How much less CO₂ does a Volta emergency power generator produce than diesel?
    On average, a Volta system produces 94% less CO₂ than a conventional diesel generator, with no nitrogen or particulate emissions on models with a fuel cell backup.
  • What's included when you rent an emergency power generator from Volta Energy?
    Every rental is fully managed through Energy-as-a-Service, including delivery, fuel management, maintenance, and remote monitoring, all in one fixed price.
  • What size emergency power generator do I need?
    It depends on the load. Volta Energy offers models from compact, low-power units for camera security and traffic control systems, up to heavy-duty systems for large construction sites and infrastructure projects.
