Temporary power without diesel
Many projects need power before the grid is available, or in locations where emissions and noise are no longer acceptable. At the same time, flexibility and fast deployment remain essential.
With Mobile Energy Storage Systems (mobile ESS) from Cellpower, you replace diesel generators with clean and silent power. Designed for temporary and off-grid applications, mobile ESS delivers reliable energy wherever grid access is limited or unavailable.
Zero emissions
Silent operations
No fuel dependency
High safety complience
Mobile & plug-and-play
Peakshaving
Integrate with solar energy
Hybrid set-up available
Designed for temporary power challenges
Mobile energy storage systems are used when:
- No or limited grid connection
- Strict emission and noise regulations
- Temporary or mobile operations
- High peak loads with fluctuating demand
- Rising fuel costs and sustainability targets
Diesel generators are increasingly restricted, while permanent grid connections are often impractical or unavailable.
Is mobile energy storage
right for you?
✅ Suitable for:
- Temporary power (days → months)
- Power without or with limited grid access
- Zero-emission, low-noise operation
- Fast deployment and relocation
❌ Not suitable:
- A permanent, fixed energy storage installation

Why switch from diesel to mobile energy storage systems?
Diesel generators are increasingly restricted in temporary power applications due to environmental regulations, noise limits and sustainability requirements.
In practice, this means limitations in locations such as:
- City centres and residential areas,
- Natura 2000 and other protected areas
- Night-time operations
In addition, rising fuel and logistics costs make diesel-based power increasingly inefficient for temporary projects. Mobile Energy Storage Systems provide a practical alternative.

| Fuel logistics | Required | Reduced | Zero |
| Urban suitability | Limited | Moderate | High |
| Deployment speed | Fast | Medium | Fast |
| Sustainability goals | No | Semi-compliant | Yes |

Hybrid setup with peakshaving
In a hybrid setup, a Mobile Energy Storage System is combined with a diesel generator. By using peakshaving, the battery system absorbs short power peaks, allowing the generator to operate at a constant and optimal load level.
This prevents inefficient ramp-up and downscaling, enabling the generator to run at a lower, fuel-efficient setting. As a result, fuel consumption and emissions are significantly reduced, sometimes up to 90%, depending on the load profile and application.
Hybrid setups are especially effective where generators cannot be fully eliminated, but efficiency, emissions and noise must be improved.
