Mobile Diesel Generator/BESS Hybrid
Many applications call for remote power solutions. There are often scenarios when businesses cannot access grid power, such as at construction sites, oil and gas operations, or during emergency-relief situations. In these instances, generators are an optimal solution. However, they are not the only option.
If you aim to cut fuel consumption, emissions, and overall operational costs without sacrificing reliable off-grid power, consider the advantages of a mobile hybrid battery energy storage system (BESS) instead of just running a generator.
Here is how these two options compare and why investing in a mobile hybrid BESS solution is ideal.
What Is a Mobile Hybrid BESS?
Mobile battery energy storage systems (BESS) are innovative technologies that store power in rechargeable batteries. When combined with a generator or renewables, like wind and solar, companies can experience greater system efficiency, reliability, and cost savings.
Think of the BESS as an energy reservoir that accumulates excess energy generated by renewable sources or the surplus power from a generator. Once the batteries are full, off-grid operations benefit from a stable, continuous power supply. So, BESS helps businesses more easily navigate the complexities of the energy transition and rising energy costs.
These systems are highly beneficial when:
- You need to maintain power during an outage (if you are connected to the grid), if the power goes out before you run out of fuel (in the case of a generator), or if there is no power from renewables.
- You want to store energy for later, benefiting from a silent, reliable power supply.
- Leveraging stored power when the grid is more expensive, such as during peak price periods (again, if you are connected to the grid).
- You have no access to power other than generators or renewables but want a more reliable or cost-efficient backup power solution.
Here are two examples.
BESS With a Diesel Generator
Say you’re running an event that requires off-grid power. When investing in a mobile hybrid BESS solution with a diesel generator, the goal is to fully charge the batteries.
You may run the generator to charge the batteries while providing power to the event, directing surplus power to the BESS. Once fully charged, the generator turns off, resulting in the following:
- Silent, zero-emission power to the load.
- Lower generator run time, benefiting maintenance variables.
- Lower diesel fuel consumption, cutting operational costs.
Once the BESS approaches depletion, the generator will start, preventing any disruptions. So, the BESS acts as the primary power source. For example, the ANA Energy 320 kW/125 kWh EBoss Hybrid can help reduce operational expenses by 50% to 80%.

BESS With Solar
A BESS can store excess power during heightened generation periods if you can access renewables like solar.
If demand spikes or you experience periods of lower power generation (such as a cloudy day), the BESS unit will provide power, smoothing out intermittency issues. As a result, you will experience a more reliable, stable energy system.
The POWR2 250 kW/500 kWh Powrbank Max unit is an example of how you can build a hybrid system. While this unit can be connected to renewable energy sources, it can also operate on diesel generators and public electric grids (if the opportunity arises). Considering that you can fully charge this unit in as little as 1.5 hours and connect to solar via plug-and-play panels, this BESS is a valuable asset to any off-grid location.
Diving Deeper Into BESS-Centered Applications for Remote Areas
While BESS units are not just for remote or off-grid applications, they are particularly valuable for such use cases. Depending on your power supply, here is what to consider. In pure off-grid situations, a BESS optimizes the efficiency of traditional generators. When a BESS is combined with a generator, the generator can run at the best point of power performance while charging the batteries. If you don’t need to run at full capacity, the BESS can kick in, so you don’t need to run a generator for a low load. This approach will help you save energy and reduce emissions.
As discussed, the second option would be to integrate a BESS with renewables, implementing a diesel generator as a backup. Renewables can charge the BESS unit. However, if the BESS plus renewable energy isn’t sufficient or during emergencies, the diesel generator can fill the gap.
If your grid coverage is unstable, you can also discuss your needs with an expert power supplier.
The BESS Market Is Growing
BESS is catching the attention of companies around the globe, especially those moving toward renewable energy generation. Data shows that over $5 billion was invested in BESS in 2022, nearly a threefold increase from the previous year. By 2030, the BESS market is anticipated to reach between $120 billion and $150 billion.
These systems are used across the entire energy landscape, especially for commercial and industrial use cases — focusing on telecommunication, data centers, hospitals, etc. The areas of interest related to this application include renewable generation, diesel generators, and uninterruptible power supply (UPS) systems.

Using a Mobile Hybrid BESS – Common Applications
As discussed, there are several environments where a mobile hybrid BESS is highly beneficial. While these applications can run generators, the operational costs will be much higher – not to mention problems from higher noise and emission levels.
- Construction sites: When starting a new housing or building development, you may not have access to power — especially on rural sites. In addition to reliable power, a mobile hybrid BESS will provide significant fuel savings based on reduced generator runtime. Once the project is complete, the unit can be re-sold. Alternatively, you can rent a mobile hybrid BESS.
- Events: Depending on the event, you may want a quiet power source. Generators can create significant noise pollution, which a BESS helps you avoid. You can charge the batteries when the event is closed (such as overnight). When attendees are on-site, you can source power from the BESS unit.
- Telecom towers: Cell towers, data centers, and broadcasting systems require continual power, either provided by generators or the grid. However, there is still a risk of outages. A mobile hybrid BESS solution will ensure power during peak loads, grid failures, or maintenance periods.
- Emergency relief: During emergencies, the grid is often down and there may be fuel shortages. A fully charged hybrid BESS unit can be brought in alongside a generator. Some examples of applications would be hospitals and communication networks. The benefit of rapid deployment and mobility ensures power is provided when needed.
- Remote operations: Many businesses need power in areas without a grid connection. Oil and gas operations and agricultural applications are two examples. Oil and gas companies may already be under pressure to reduce emissions. A hybrid BESS helps significantly reduce CO2 emissions, supporting a company’s carbon reduction strategy.
Comparing a Mobile Hybrid BESS vs. Diesel Generators
The benefits of implementing a mobile hybrid BESS are clear: higher fuel efficiency, reduced maintenance, lower costs, and a more environmentally friendly solution. However, nothing beats the hybrid approach — especially when you cannot afford any downtime. Sure, you can use a generator to power your equipment, but the cost of diesel is rising — not to mention the required critical maintenance. Also, generators tend to operate best at a steady load, which is not always the case.
Here are some key considerations surrounding mobile hybrid BESS solutions vs. diesel generators alone.
- Efficiency: A BESS can handle rapid load changes and fluctuations, which will help extend the generator’s operational life.
- Noise: While noise is not always a concern, you may operate close to noise-sensitive or residential areas. A BESS can help you reduce noise pollution, which may be a requirement for continuing to operate.
- Emissions: If you run generators on-site less often, you’ll reduce your carbon footprint. For some companies, this is crucial regarding local or state regulations.
- Response time: If your power demand changes, a BESS can almost instantaneously respond, which can help improve power quality.
- Grid support: If relevant, BESS can support load balancing, voltage regulation, and peak shaving concerns.
- Reliability: If there is a sudden outage, a BESS can provide instant power to support uninterpreted operations. A generator can recharge the battery or provide long-term support if needed. Speak with your power provider about using a mobile BESS with UPS systems.
- Cost savings: A fully charged BESS can handle your power needs, so your diesel generator doesn’t need to operate at full capacity. The fuel savings can be significant if you’re running an off-grid site. Lifespan is also a consideration, as generators typically last around ten years — compared to BESS units, which can last 20+ years.
Moving Toward BESS Paired With Renewables
The benefits surrounding renewables are obvious — cost savings, lower environmental footprint, and increased energy independence.
Many companies, especially those in the oil and gas industry, must start transitioning toward lower-carbon energy systems. Renewables are paving the way. However, there are still concerns — the sun doesn’t always shine; the wind doesn’t always blow.
The solution?
Energy storage, including reliable BESS units, remains the cornerstone of energy transition strategies.
When combined with generators, these industrial units ensure backup power is never a concern. Whether you’re concerned about extreme weather events or unplanned outages, integrating renewables alongside energy storage systems will help you remain competitive in the coming years.
With the help of a critical power supplier, you implement a complete backup or off-grid power solution, including BESS, for a stable energy supply.
