How To Choose The Right Industrial Generator For Your Business

How To Choose The Right Industrial Generator For Your Business

Choosing an electric generator depends on important factors such as your specific applications, power needs and facility size. With the right generator, you can back up your power supply and keep operations going during outages and emergency situations. Understanding how to choose an industrial generator can help you significantly improve your business.

Importance of Choosing the Right Generator

The right generator is essential for your company’s productivity, efficiency and peace of mind. Choosing the right generator is crucial for the following reasons:


A generator is necessary for safety if your facility operates life-sustaining or life-saving equipment. For example, a hospital must keep its medical equipment running for patient health and safety during a power outage. Additionally, your facility requires a generator for safety systems such as fire alarms and emergency lights.


The right generator allows your company to continue operations when it loses power. This backup power supply enables you to improve efficiency by reducing machine downtime and increasing productivity.

Choosing an Industrial Generator for Your Business

Consider the following factors to understand how to choose an electric generator that suits your requirements:

1. Type of Generator

The first step in choosing an industrial generator is determining what type of generator you need.

  • Primary generator: A primary generator serves as a facility’s main energy source. Using a primary generator can help your company decrease its carbon emissions and reduce utility bills. Decreasing carbon emissions supports a healthier environment. A primary generator can also help you meet your facility’s power requirements if your local grid is located too far away or provides inadequate power.
  • Standby generator: A standby generator is an independent power source that can keep an entire facility operating during an outage. It automatically turns on when it detects a primary power source failure, minimizing delays and disruptions to maintain machine uptime. A standby generator is ideal for your company if you depend on your systems for production and need to maintain operation at all times.
  • Emergency generator: An emergency generator powers crucial systems. While it doesn’t maintain operation for an entire facility, it reliably delivers temporary power to safety systems such as fire alarms, emergency lights and medical devices necessary for patient survival. The National Fire Protection Association’s NFPA 110 code requires your company to install an emergency generator for any systems critical for human safety.

2. Machinery Voltage and Power Needs

After determining what type of generator your company needs, you must consider how you intend to use it and how much power you need. If you run a smaller company, a single-phase generator may be sufficient. However, larger companies typically require three-phase generators to support a substantial electrical demand.

Understanding your facility’s electrical systems and their voltage requirements can help you choose the right generator. For example, a single-phase generator produces 240 volts and can power basic electronic systems. A three-phase generator is typically ideal for industrial applications because its voltage supply can support heavy machinery. If your company operates large machines, you most likely require a three-phase generator.

3. Facility Size

Your facility’s size also plays a role in whether you need a single-phase or three-phase generator. You may choose a single-phase generator to back up a small building on your property, but you most likely require a three-phase generator if you need to power a large facility.

Your available space is another important consideration. Check a generator’s dimensions before ordering it to ensure you have the space to accommodate it. While your industrial operations most likely require a large generator, you must ensure it will fit in the area you plan to install it. 

Scheduling a professional sizing evaluation by an experienced electrician is the best way to determine the right size and make an informed decision.

4. Potential Company Expansion

Company expansion is another important factor. Predict or estimate how much your company may grow and how much power you may need before investing in a generator. For example, if you only need to power a couple of machines now but plan to add five heavy machines in the next couple of years, a larger generator is the ideal choice.

5. Environmental Factors

In addition to your facility’s size, you must think about several environmental factors to ensure your generator can withstand its surroundings. For example, a generator must be durable enough to handle weather conditions if you plan to install it in an outdoor area where inclement weather is likely. Matching a generator to environmental conditions helps extend its life span and save you money on repairs.

Important environmental points to note include:

  • Set duty
  • Supply rating
  • Electrical system connection
  • Altitude and ambient measures
  • Emissions
  • Voltage regulations
  • Potential expansion capacity

6. Fuel Type

Industrial generators use different fuel types. Compare these fuel types to understand how they affect your purchasing decision:

  • Diesel: Diesel generators are typically the best choice for industrial applications because they efficiently provide high power. They are also highly reliable and durable, and they require little maintenance.
  • Natural gas: Natural gas costs less than diesel fuel, but gas generators typically supply less power than diesel generators.
  • Propane: Propane is typically more eco-friendly than gas, but it works less efficiently.
  • Solar: A solar power generator is the most eco-friendly option, but it is less durable than other options.
  • Petrol: Petrol is typically the most expensive fuel type.

7. Portability

Stationary generators are typically a better choice for industrial facilities than portable generators because they can support higher power requirements. Since a stationary generator remains on site, it can activate at any time, even if no workers are present during an emergency. Stationary generators typically cost more than portable ones, but their capabilities are worth the cost and can help your facility save money on machine downtime.

8. Brand

Choosing a generator from a reputable brand and trustworthy vendor is essential. A quality brand manufactures generators you can depend on, and a trustworthy vendor can ensure you choose the best choice for your company’s needs.

Examining a vendor’s website and customer reviews is an excellent way to determine if they are reliable. An experienced vendor should display professionalism and knowledge about the products they offer. Customer reviews reveal the experience, service and product quality you can expect from a vendor. Additionally, looking at the brands that reputable vendors sell can indicate which ones you should consider purchasing.

9. Budget

While your available finances are an important factor because you want to avoid exceeding your budget, it’s also important to assess how a quality generator can help you save money long term.

Since the right generator can keep your important machines operating during an outage, it can maintain production and help you make your target profits. A well-maintained quality generator that appropriately meets your needs can also last longer than other models, helping you save money on repairs.
