“How Many Kilowatts (KW) Do I Need for My Dulles, VA Commercial Backup Generator?” is the first question to ask when purchasing a backup generator for your company. The idea is to figure out what types of machinery you’ll need to operate if you don’t have access to utility power and how much power they take.
Make a list of the devices and instruments you’ll need to keep running during your operation and the wattage required to start and run each one. Much of this information may be discovered in the equipment’s owner’s manuals, on specification plates attached to the equipment, or with the assistance of an electrician.
The key to backup generators is evaluating your essential power needs. What necessities will you need to keep going if the electricity goes out? For a rough estimate, add up the voltage needs depending on your equipment specifications. Here’s a more detailed response to the issue raised in the previous paragraph.

Full Load Method
You can follow the steps mentioned below to estimate the right size of a commercial generator you may need for your business. This method is known as the full load method.
- The first step in this method is to determine the total amps consumed by your business during the peak load time.
- Now, divide the total amps by two for a single-phase, and for a three-phase, divide the total amps by three. In the next step, multiply the total amps obtained by the voltage supply followed by a thousand to get the figure in the total kilowatts.
- You can also refer to the National Electrical Code website to find out the Full Load Capacity of your company depending upon the equipment you use in your business.
- Now add some buffer by calculating the Reserve Capacity. It is usually calculated as 25 percent of the Full Load.
- The next step is to multiply the total amps with Supply Voltage/1000 to calculate the Full Load in Kilowatts.
- Now, Reserve Capacity + Full Load Capacity will give you the required total capacity of your commercial generator.
Square Footage Method
This is a much simpler method to size your commercial generator. This method adds 50 kilowatts to 5 additional watts per square foot.
