Mobile networks are growing. More cell towers, at more locations, each requiring a continuous and dependable supply of power. At the same time, grid congestion makes a fixed connection increasingly impossible or impractical at a growing number of sites. Telecom tower companies need an energy solution that doesn't wait for a grid connection to be arranged. Volta Energy delivers just that.
A Volta operates fully off-grid. No waiting for a grid connection, no delays in rollout. New tower sites are up and running within an hour.
The combination of solar panels, smart batteries and a biofuel backup guarantees continuous power delivery. Day and night, summer and winter, sun or rain.
Volta systems achieve an average CO₂ reduction of 94% compared to conventional diesel generators, saving thousands of litres of diesel every week.
We monitor all systems remotely. Real-time visibility into consumption and status per site, with no one needed on location.
Cell towers are rarely located next to an available grid connection. They sit on rooftops, alongside motorways, in rural areas and at sites where a fixed grid connection can take months to arrive. In the meantime, energy consumption per tower is increasing as 5G rollout accelerates and data demand grows. Grid congestion makes it harder still: even where a connection is available, the capacity is often nowhere near sufficient.
The default solution is still too often a conventional diesel generator. It works, but it comes at a cost: high fuel expenses, significant CO₂ and nitrogen emissions, a constant maintenance burden and a growing conflict with the sector's own sustainability commitments. On top of that, ESG requirements and emission standards are tightening. The pressure to decarbonise is increasing, while the operational demands for uptime and reliability remain as high as ever.
A Volta is a 3-in-1 mobile energy system: solar panels as the primary source, smart batteries for storage and a biofuel backup that kicks in automatically when demand exceeds generation. The system manages itself based on real-time demand and available output, with no manual actions and no one required on site.
For telecom applications, this means an energy solution that is independent of the grid, immediately deployable at new sites and scalable from smaller installations with few mobile operators to larger tower sites with higher power demands. We advise based on the specific situation and power requirements of each location.
The first generation Volta, with HVO100 as backup, already achieves an average 94% CO₂ reduction compared to conventional diesel generators. The Volta ZERO series, with a methanol fuel cell, is fully nitrogen-free and particulate-free and whisper-quiet in operation. The right choice for sites with strict emission requirements or in areas where low-emission zones apply.
Volta Energy delivers more than just the hardware. Through our Energy as a Service model, we take full care of energy management. Delivery, installation, fuel management, maintenance and remote monitoring are all included in a fixed all-in-one price.
For telecom tower companies managing multiple sites, that is a real advantage: no separate contracts per site, no unexpected fuel or maintenance invoices and no operational burden on location. We monitor and report centrally.
You run the network. We manage energy supply.
