Comparison of variant costs
Why consider Hybrid or MES?
When Hybrid makes sense
- With high power peaks and large load variability.
- When you need to stabilise the generator's operation over the daily cycle.
- When reducing fuel cost without the risk of power shortage is key.
When MES is the better choice
- When power is needed without a generator, mainly for shorter periods or in emergencies.
- When the priority is reducing emissions and limiting generator operation.
- When the project requires flexible scaling of the number of units.
Fuel cost reduction
Reducing generator running time and optimising energy consumption.
CO2 emission reduction
Lower emissions while maintaining power stability.
Power peak stabilisation
Covering momentary demand spikes without oversizing the generator.
Flexible configuration
The ability to scale the system to the project size.
Frequently asked questions
See how the NJORD calculator works and how MES systems can genuinely reduce energy costs and CO2 emissions.
MES is a mobile energy storage system. It can work autonomously or together with a generator.
Hybrid is the Generator + MES scenario, in which MES covers peaks and variable loads. The battery also works at very low or momentarily zero load, reduces the generator's idle running and often allows a smaller generator to be selected.
The calculator analyses the real power profile over a 24-hour cycle and converts it to the selected operating period. We simulate fuel consumption, equipment rental cost, MES energy cost and CO2 emissions.
We then compare the base Generator variant with the Hybrid and MES solutions. You get real cost data based on operational parameters. Want to check the savings potential for your project? Contact us and receive a dedicated analysis.
The cost covers equipment rental, fuel (Generator/Hybrid) or energy at a rate of PLN 900 net/MWh (MES) and the number of operating days. Transport cost is not included in the calculator — delivery terms are agreed individually.
The calculator takes into account the full operating cost of the project. This way you see the real cost of deploying the system.
System selection is based on the maximum power peak, average load, profile variability and the number of operating days.
We analyse many configurations and choose the solution with the lowest total cost.
Hybrid works well with high power peaks and large load variability. MES without a generator is most often suitable for shorter operating periods and emergency scenarios.
MES can work without a generator in selected scenarios, while Hybrid is the Generator + MES scenario, in which MES takes over peaks and reduces the generator's running hours.
The calculator lets you compare both scenarios and choose the most cost-effective variant.
We calculate the generator's emissions based on fuel consumption converted to kilograms of CO2. For MES we account for the emissions attributed to the delivered energy.
The result shows the real emission reduction compared with the generator.
No. The calculator does not include transport or travel costs. The MES variant covers equipment rental and energy cost at a rate of PLN 900 net / MWh.
Delivery and logistics terms are agreed individually outside the calculator.
MES can cover short-term power peaks thanks to its energy management strategy.
For long-lasting peaks the system may indicate the Hybrid variant as more stable.
The results are indicative and serve to compare scenarios. Every project is preceded by a technical analysis and an offer tailored to the investment conditions.

All amounts in the calculator are presented as net. VAT is not included, because its rate and settlement method depend on the type of service and the contract terms.
