When planning an event or preparing your business for potential power outages, one of the most critical steps is ensuring you have the right generator to meet your power requirements. Renting a generator that’s too small can lead to equipment failure, while renting one that’s too large can be an unnecessary expense. In this guide, we’ll walk you through how to accurately calculate your power requirements before renting a generator, ensuring you get the perfect fit for your situation.
Why Understanding Your Power Needs is Essential
Understanding your power needs is crucial to ensure uninterrupted power supply during an event or a power outage. A generator that’s not adequately sized can cause overloads, leading to potential damage to the generator or connected equipment. On the other hand, a generator that exceeds your power needs might result in wasted resources. By accurately calculating your power needs, you can avoid these issues and ensure smooth operation.
1. Identify All Essential Equipment
The first step in calculating your power needs is to list all the equipment and devices you’ll need to power with the generator. This might include:
-
Lighting Systems
-
Sound Equipment
-
Computers and IT Systems
-
Heating or Cooling Systems
-
Kitchen Appliances (for events)
-
Medical Equipment (for healthcare facilities)
Tip: Don’t forget to include smaller devices that might be easy to overlook but still contribute to the overall power demand.
2. Determine the Power Consumption of Each Device
Once you’ve listed all the essential equipment, you need to determine the power consumption of each device. This is usually measured in watts (W) and can often be found on the device’s label or in the user manual. If the power consumption is listed in amps (A) instead of watts, you can convert it using the formula:
Watts=Volts×Amps
Tip: Remember that some devices, especially those with motors, require more power to start up (starting wattage) than they do to run (running wattage).
3. Add Up the Total Power Requirements
After determining the wattage of each device, add them up to calculate your total power needs. This total gives you the baseline wattage your generator must handle. However, if you have devices with high starting wattage, you’ll need to factor in this surge to ensure your generator can handle the initial power spike.
Example: If your total running wattage is 8,000 watts and your equipment requires an additional 3,000 watts to start, your generator needs to handle at least 11,000 watts.

4. Factor in a Safety Margin
It’s a good idea to add a safety margin to your total power needs. This is to account for any unforeseen power requirements. This ensures that your generator isn’t running at maximum capacity, which can reduce its lifespan and efficiency. A common recommendation is to add 10-20% to your total wattage.
Tip: If your total power needs are 11,000 watts, adding a 20% safety margin would bring your required generator capacity to 13,200 watts.
5. Consider Future Power Requirements
If you anticipate that your power needs might increase in the future—due to business expansion, additional equipment, or larger events—it might be wise to rent a generator with a slightly higher capacity than your current requirements. This foresight can save you from needing to rent a second generator or upgrade in the near future.
