Commercial generator installation is a must for buildings and businesses nowadays due to unexpected power outages. In the U.S., electric consumers experienced no power for about four hours in 2016.
Electricity service interruptions happen due to various causes, such as bad weather or major events like floods or hurricanes.
With no power, you’re most likely to close or suspend your operations. You will miss out on serving clients, losing much-needed sales in the process. Thus, it’s better to install a commercial generator. It can keep your business running while waiting for the power to come back.
Additionally, several commercial buildings and enterprises need to run 24-7. Thus, the need to install a commercial backup generator to continue its operations. Hospitals, logistics, back-office support, hotels, and many other buildings will need a commercial generator on standby.
With that, how do you know which generator to buy and install for a commercial building? Keep in mind some of these factors when choosing.
Consider These When Buying a Commercial Backup Generator
Before you purchase a commercial backup generator, you have to choose and compare available equipment from vendors. The price of a commercial generator alone is not the sole factor to consider. Here are a few of what you also need to look into:
Commercial generators range from 20 kW up to 2500 kW, depending on the requirements of the property. You have to identify first how much power you will need to operate. For retail, you will need around 50 kW and add 10 watts per square foot. Commercial facilities require at least 50 kW and another 5 watts per square foot.
Then, to maximize the generator for commercial applications, know its surge capability. You can do this by determining both the energy needed to turn on and run the equipment connected to the generator. Additionally, the load factor will also depend on the peak demand for your electrical devices.
There are different types of fuel for a commercial generator. The most common is diesel generators. Alternatively, other commercial generators also have natural gas, propane, or petroleum as their fuel source.
Each generator can only run on one type of fuel. Thus, you need to ensure that you have access to the specific fuel for the generator you’ll be using. Factor in how much it will cost and which fuel type is more likely to provide adequate power coverage.
The cooling system is another feature you have to know about a commercial generator. As generators operate through extended periods, generators tend to heat up, which is a safety concern. There are two types of cooling systems: the air-cooled and the liquid-cooled generator.
An air-cooled generator is a less expensive option as it’s a much simpler system. It generates air to cool down a commercial generator. Air-cooled generators have a wide range of use, and they’re the ones that produce more noise when running. The liquid-cooled generator, on the other hand, has a more robust cooling system that operates quietly. This type of generator is more effective and, thus, more expensive.
Some reliable commercial generator manufacturers include Caterpillar, Kohler, Cummins, Generac, and many others. When choosing which brand, you need to know how reliable the manufacturer is in building and servicing generators.
Each generator brand can have different equipment and units available that will fit your specific commercial operation. Match your required generator size, fuel, and cooling system against the ones available from the brand. This way, you will already narrow down your choices.
Consult with a certified electrician who can best advise which adequate commercial generator your business will need. They will make sure that the generator you’ll be choosing can sufficiently meet the demand of your commercial property.

The price will reach $10,000 to $25,000 for mid-size equipment such as HVAC, security systems, and workplace computers. And to fully power a warehouse, the generator installation can cost up to $125,000.
Their service cost will vary depending on the complexity of your commercial building. The contractor will factor in the local climate or retrofitting requirements of your facility.
