What Factors to Consider for Selecting a Generator?

Selecting a Generator

In the world of construction, manufacturing, and industrial purposes, generators are vital for the process. This machinery powers most of the systems in infrastructure projects, construction sites, and other domains. 

Generators are handy in matters of productivity for companies and are a versatile power source. These tools help provide necessary energy and aid to different applications, varying in type and capacity. For example, some generators are suitable for powering mobile kitchens/industrial equipment while others provide high amounts of energy to buildings like hospitals/manufacturing companies. 

Despite the availability of so many options, and sometimes because of it, choosing the right type of generator is a complex process for companies. If you are planning on investing in it, you need to consider particular points, like generator features and the job site, before reaching out to the best generator suppliers in Dubai. Here, we shall discuss them more extensively. 

  1. Portability 

Generators come in portable and stationary variants, and each option is suitable for particular types of companies and operations. If you run a smaller company, buying a big stationary machine would rack up your costs and is harder to manage. 

Comparatively, portable generators are efficient alternatives. For conglomerates, the stationary version can maintain their high energy demands. 

  1. Power Output Rating 

Consider the power outing rating of the generator types; this is important to know beforehand in case of power outages. Calculate your power requirements and size your generator to see if all the essential equipment parts run efficiently even under high pressure. 

For industrial applications or large buildings, bigger generators with kW power output ratings are suitable. 

  1. Control Systems/Management 

While searching for generator suppliers and buying a generator component, consider their control system condition. The best ones deliver many features, like display warnings (e.g., low fuel indicator), remote machine start-up/programming, and analytical data. In power plants, it makes it easier for operators to utilize this equipment and monitor the operations. 

Many generators come with PMS (Power Management Systems) that are useful for optimizing their performance keeping with the changing load demand and the fuel consumption rate. Generators are safer from overuse or under-utilization damages and run longer. 

  1. Fuel-Based Considerations 

Another thing you should consider is the type of fuel for the generator you are buying or renting. Common types of commercial generators based on their fuel type are natural gas and diesel generators. The factors you should focus on here include:

  • Early costs- Check the upfront cost of the installation process and the machine itself. 

  • Repair and maintenance- You need to maintain both types frequently. However, diesel generators do not need too much maintenance.

  • Fuel cost- Find out how much fuel the generators you are considering run on for a set period. 

  • Fuel storage- Natural gas generators connect with the primary gas pipeline, so there is no need to worry about storage. On the other hand, diesel generators work after attaching a tank to the unit's base. Also, if the machine comes with a smaller tank, you have to refuel it regularly. So, you would have to store extra diesel fuel reserves for the generator on-site. 

  • Noise- During operations, diesel generators make high decibel noise while natural gas generators are quieter. 

  • Safety- Natural gas is very combustible while diesel fuel is not. Plus, it is a pungent odor in the liquid version. Thus, if there is any leak in the machine, it is easier to detect the point of origin and fix it on time. 

  1. System Autonomy 

The best generator suppliers in the UAE offer options with autonomous functionality among generators. Ones with the Automatic Transfer Switch (ATS) feature promptly start operating within seconds in case of power outages. 

After the main power grid starts operating as normal, the ATS-based generators shut down automatically. It is a better option for companies who do not have staff on-site who can manually switch on/off the machine during emergencies. 

  1. Modular Capacity

Some standard generators can work with other units in a modular set-up at the power plant for more power output. Consider options with this feature and the duration of setting up two units in pairs. Some of the generator options take only 10 minutes maximum for this process while others take longer. 

Among the options available, plug-and-play generators stay consistent with the on-site energy requirements. When there is a high power demand, all units become active while just one/two units stay running during low load periods. Additionally, generators with modular capability are more reliable, and their service interval periods are smaller.

  1. Size 

Commercial generators come in different sizes. You should consider the facility's dimensions to decide the size of the generator you would put on-site. Here, consider the generator installations you would handle off-site and the space of the generator room. 


Overall, it is better to carefully check all factors about the machine itself, its capacity/range, and your on-site structure first-hand. Depend on reliable suppliers to get the best equipment and additional maintenance/servicing support. Also, settle on your main requirements for the company and projects, and then choose a compatible generator option.
