How Do You Choose The Right Commercial Generator For Your Company?


Usually, commercial properties are held to the highest of standards. This, therefore, goes beyond basic liability, insurance, and safety standards. Tenants and businesses renting space in a large commercial building have particular expectations regarding resource availability. This is especially true for businesses in the foodservice, animal care, sensitive goods, data centers, and medical supply industries, and rely on efficient electrical service to keep temperature-sensitive materials safe and preserve valuable property.

Many business properties will use a huge emergency generator to keep a steady power supply for tenants, customers, and other sensitive areas when the typical power grid goes down.

If you’re a commercial property manager or owner, you might be asking what the best commercial diesel generators are for your company’s protection.

The truth is that this is a crowded market with lots of high options to examine. It helps to ask some important questions and account for some specific factors to help you go through them and pick the finest commercial generator for your business.

What Is a Commercial Standby Generator and How Does It Work?

Commercial generators, often known as “Stand By Generators,” are set up to monitor the system and automatically start working when the light goes out. Some of these systems do, nevertheless, require a person to turn on a switch or press a lever.

Even so, the number of quality modern standby business generators contain an electronic transfer switch that cuts the utilities line in the event of a power outage. The restoration of power is almost immediate, which is important for a property with temperature-sensitive goods or equipment. The transfer switch then quickly switches off the generator and returns to standby mode when power from the grid is reliably restored.

It’s also worth noting that even huge equipment or a high-value Industrial generator has a much stronger build quality and safety features than the top commercial backup generators. The majority of them make use of thicker gauge steel with reinforcing design components. A high-quality commercial standby generator’s engine is also larger, and it’s usually liquid-cooled for better performance and less risk of a breakdown due to overheating. Surge protectors that are specifically built to handle the increased wattages and heat associated with extended run times as well as high demand will also make the inside electronics more reliable.

What Is A Prime Power Generator?

When the usual power grid is unavailable, a primary generator can be used to produce significant electric power for extended periods of time in commercial power applications. This is more common in areas where severe storms and other natural disasters can take out power for days at a time, with no realistic chance of restoration in a reasonable timeframe.

  • to save profit on utility power
  • Using natural gas to reduce the carbon footprint
  • To provide power to a facility that is too far from the power grid.
  • When the local grid is unable to meet the facility’s power requirements, energy should be provided.
  • To satisfy peak energy requirements beyond what the power company usually supplies.

These Primary Generators are designed to run 24 hours a day, 7 days a week for places where grid access may be unavailable for an extended period of time with good maintenance. A hospital in a known earthquake zone or a place where strong hurricanes are frequent, for example, can pick a high-capacity primary generator to assure reliable power for patients and to keep temperature-sensitive medications cool.

Emergency Power

Emergency power generators provide a backup source of power for life safety systems, but they won’t being able to power your entire facility in the case of a power outage. During a blackout, they reliability power to a few operations, including emergency exit lights and fire alarms. An emergency generator can only connect to a restricted number of emergency systems utilising separate wiring from the facility’s main systems, according to the National Electric Codes (NEC) Section 700.

How To Choose The Right Commercial Power Generator

When it comes to choosing the best commercial standby or primary generator for your property, there are a few important factors to explore.


There are several important aspects to consider in calculating the amount of commercial generators you need. When determining the size of a residential generator, it’s not as simple as adding up the wattage of priority items. Consult a professional electrician to determine the amount of a commercial generator you’ll need to keep your property going at a decent level of service. They have the knowledge and experience to precisely calculate the power requirements for critical equipment and climate controls, as well as other factors that can affect the scale.

The Fuel Types

You might be surprised to learn that a commercial generator can run on a variety of different fuel types.


Gasoline commercial generators are popular since they are readily available and often easier to refill than other generator fuels. They are, though, less fuel efficient than diesel equivalents of similar size and scale.


Diesel is also readily available, though not as readily as gasoline in some areas. It gives a lot of power and is more fuel efficient. Though it might not be the best solution for an unsheltered emergency generator in a very cold climate.


Propane is usually accessible via municipal lines as a byproduct of petroleum production. If you wish to use a propane generator in a seismically area, you must consider having a reinforced liquid propane storage tank installed on-site to offer a long-term supply in the event that municipal lines go up.

Natural Gas

Natural gas has become more popular for powering generators due to higher distribution through municipal lines and clean-burning energy efficiency. A compressed natural gas storage tank may not be sufficient for meeting long-term power needs in the event of a prolonged natural gas Generator that cuts off access to the power grid, as it is typically only available through municipal lines and has only a third of the energy density of propane.
