Mobile Energy Supply of the Future – More Economical and Powerful Than Ever

Are your temporary energy supply costs exploding? Between unpredictable diesel prices, high maintenance requirements, and hidden costs for refueling logistics, operating diesel generators is increasingly becoming a financial burden for construction projects, events, and industrial applications. Every generator running inefficiently at partial load is literally burning your budget.

The crucial question is no longer whether there's an alternative, but how quickly you can benefit from it. The answer lies in proven and economically superior technology: the emost Butler battery storage system.

Save real money by intelligently supplementing your diesel generators with batteries or, in many cases, replacing them entirely. By massively reducing expensive generator operating hours, your fuel and maintenance costs drop by up to 90%.

But the financial advantage is just the beginning. Imagine a construction site without the constant noise and exhaust fumes of a generator. Your employees work in a healthier, more pleasant environment, operational safety increases through uninterrupted power supply, and compliance with environmental regulations becomes child's play. These additional benefits ensure high team acceptance and position your company as a modern, responsible partner.

This whitepaper shows you, using real data and four concrete use cases, how switching to emost Butler battery storage is not only ecologically sensible but, above all, one of the smartest economic decisions for your temporary energy supply.

System Comparison: Why a Butler is More Than Just a Battery

At first glance, both diesel generators and battery storage systems deliver power. However, the fundamental differences in operation, efficiency, and reliability are enormous. While a conventional diesel generator must run permanently to provide power – even when only a small load is applied – the emost Butler operates intelligently and on-demand. It delivers energy absolutely silently and emission-free from its storage and activates an external charging source, such as the power grid or a generator, only when really necessary.

This leads to decisive advantages: Operating efficiency is enormously high because the generator – when needed – only runs in its optimal efficiency range for charging, instead of inefficiently puttering along. Butler maintenance is minimal since no consumables like oil or filters are required. In terms of operational safety, the Butler offers reliability through its UPS function and IoT remote monitoring that a single generator can never achieve. For projects in cities or sensitive environments, noise- and emission-free operation is often the key to smooth approval.

The True Costs: TCO in Focus

A pure comparison of rental prices distorts the picture. What matters are the total costs over the project duration (Total Cost of Ownership). Our analyses show that the emost Butler often compensates for potentially higher rental or purchase costs within just a few months through drastic savings in fuel, maintenance, and logistics. In our calculations based on real project data, we were able to demonstrate total cost savings of up to 56% over a ten-year period.

Four Proofs from Practice: Where the Butler Makes the Difference

Case Study 1: Uninterrupted Water Management in Biel

For securing a construction pit, six pumps had to be operated with absolute fail-safety. Instead of a loud and expensive diesel UPS solution, two emost Butler S units were deployed, connected between grid and pumps. The result was guaranteed, uninterrupted power supply with automatic alerting, while the need for an emergency diesel generator was reduced by over 90%.

Case Study 2: Efficient Construction Site Supply in the High Mountains at Sufers/Splügen

The challenge was to supply two large construction cranes with extreme starting currents. An emost Butler M served as the central energy buffer. Instead of an oversized, permanently running generator, only a smaller diesel generator was used, which efficiently charged the Butler only when needed. This reduced generator runtime to only 20% of total operating time, saving thousands of liters of diesel and enormous costs.

Case Study 3: Peak Shaving for a Concrete Mixing Plant in Austria

A mixing plant required high peak loads of up to 90 kVA. Instead of running a large 150 kVA generator for this, two emost Butler S together with a link covered these load peaks. They were charged cost-effectively at night via existing construction power. The monthly cost comparison was clear: The setup with the emost Butlers was around €4'900 or 43% cheaper than the pure diesel solution, mainly driven by the avoidance of Diesel consumption.

Case Study 4: Autonomous Water Management in Hybrid Operation on the A6 Muri-Rubigen

During renovation of the emergency lane, water management had to be operated completely without construction power connection. The standard solution would have been a 24/7 running diesel generator – loud, maintenance-intensive, and expensive. Instead, an emost Butler S was installed as the primary energy source, intelligently recharged by a small 20 kVA diesel generator. The battery controlled the generator and only switched it on at 35% charge level and off again at 70%. The result was a 90% reduction in diesel operating time, leading to massive savings in fuel, service costs, and refueling logistics while simultaneously providing reliable and quiet energy supply.

Conclusion and Recommendation: The Intelligent Path to Clean and Affordable Energy

Battery storage systems are the logical evolution of temporary energy supply. They are not only an ecological necessity but, above all, an economically superior solution. Switching to the emost Butler is particularly worthwhile when load profiles fluctuate strongly, noise and exhaust emissions are critical, 100% fail-safety is required, or you simply want to significantly reduce your operating costs.

Start by analyzing your load profile and comparing total costs. You will quickly realize that the path to quieter, cleaner, and more cost-effective energy supply begins with your next project.
