An event without power is not an event. Whether it is a festival in a city park, an outdoor trade show on an industrial site, an open-air concert or a temporary event at a location without a grid connection: the power supply determines whether the program runs. Volta Energy delivers 3-in-1 mobile energy systems that take care of it. Silent, clean and fully managed.
More and more event organisers, venue managers and production companies are looking for an alternative to the diesel generator. Municipalities impose emission requirements. Park managers and local residents complain about noise. Clients and commissioning parties expect a sustainable operation. A diesel generator no longer fits that picture.
A Volta does. Our 3-in-1 mobile energy systems combine solar panels, smart batteries and a biofuel backup in one. Silent in standard operation. 94% less CO₂ production on average compared to a conventional diesel generator. Ready to deploy at any location, without a grid connection.
A Volta is plug-and-play. We deliver, install and verify operation. You connect your equipment. After that, the system runs itself: during the day the solar panels charge the battery, the battery powers the event. When capacity falls short, the biofuel backup kicks in automatically. No buttons to press, no refuelling to organise, nothing to think about.
We monitor every system 24/7 remotely and handle all fuel management. If anything needs attention, we know before you do.
A Volta is deployable for any event that needs power at a location without a fixed grid connection, or where a silent and clean energy solution is required. Common applications include outdoor festivals and open-air concerts, markets and street fairs on squares or in parks, temporary trade shows and exhibitions, on-location sporting events, film productions and outdoor shoots, and community events and municipal activities in public spaces.
For smaller events with a low power demand, our compact models are the right choice. For larger festivals with high power requirements distributed across multiple stages and exhibitors, we supply more powerful solutions up to 108 kW peak output. We advise based on your specific programme and power requirements.
At the Hoogte 80 Festival in Arnhem, Volta Energy supplied one 15 kVA and two 45 kVA solar systems across a challenging hilly park site. The result over three days: 2,096 kg CO₂ saved and €446 in fuel cost savings compared to conventional generators. The organiser returned for the next event.
A conventional diesel generator at an open-air concert or in a city park is a problem. Noise levels of 80 to 100 dB compete with the programme and generate complaints from local residents. A Volta runs silently in standard operation. Only when the backup is active there is noise: a maximum of 60 to 63 dB(A) at 7 metres. And the backup only activates when it is genuinely needed.
For the most noise-sensitive situations, such as classical concerts, film screenings or events in residential areas, the Volta ZERO series is the right choice. With a fuel cell as backup, the system is whisper-quiet at every moment of the day.
Events in parks, nature areas or urban environments are increasingly subject to emission requirements as a condition of their permit. Municipalities and provincial authorities set limits on CO₂, nitrogen and particulate matter at temporary event sites. A Volta meets those requirements with room to spare. Our systems achieve an average of more than 94% CO₂ reduction compared to a conventional diesel generator. On models with a fuel cell as backup, the system is fully nitrogen-free and particulate-free.
That not only makes it easier to obtain a permit, but also to keep it for repeat editions of the same event.
With Volta Energy, you rent more than hardware. Delivery and transport to site, installation and commissioning, fuel management, maintenance and 24/7 remote monitoring are all included in one all-in price. At the end of the event, we collect everything.
You organise the event. We make sure the power is always there.
