What to Consider When Sizing Your Construction Generator

High rise interior construction crew - What to Consider When Sizing Your Construction Generator

One of the most important decisions you’ll need to make when setting up a construction site is choosing the right generator. The generator serves as the heartbeat of the site, providing much-needed power to all your construction equipment. But what do you need to consider when sizing a generator? In this article, we break it down for you.  

Why Generator Sizing Matters 

First, it’s crucial that you understand why the size of your generator matters. A generator that is too small may not be able to power all your equipment. This could lead to project delays and unwanted downtime. Conversely, a generator that is too large for your needs can result in unnecessary fuel consumption and increased costs. 

Additionally, generators perform best when they operate between 70% to 90% of their full capacity. By keeping this in mind, you can ensure optimal fuel efficiency and prolong the generator’s lifespan by reducing wear and tear.  

The Size of Your Construction Site 

One of the first considerations when sizing your generator is the size of your construction site. Larger sites may require more power to run equipment, while smaller sites might not need as much power.  

However, keep in mind that the physical size of your site isn’t the only factor; it’s the power consumption of your equipment that determines the size of your generator. That said, with a larger site usually comes more personnel and more equipment, so it’s a good place to start.  

The Equipment to be Powered 

What equipment will your generator be running? Make a list of all the equipment that you’ll need to power—from the very small to the very large (think cranes)—and their individual power requirements. This will help you determine the total load that your generator will need to handle.  

Don’t forget to include tools and appliances such as lights, heating or cooling equipment, and even chargers for battery-operated tools. If your generator is going to be providing temporary whole-site services, it needs to be sized to handle the peak load. 

Voltage Capacity and Phase 

You must consider the voltage capacity and phase of a generator when sizing one. Most construction equipment runs on three-phase power due to its efficiency and power density, but some smaller tools might only require single-phase power. 

Voltage capacity, on the other hand, refers to the maximum amount of electrical potential your generator can produce. You’ll need a generator with a voltage capacity that matches or exceeds the total voltage requirements of your construction equipment. 

Final Thoughts 

By understanding your site’s size, the equipment you need to power, and your generator’s voltage capacity and phase, you can choose the perfect generator for your site.  

Remember, it’s always better to slightly overestimate your power needs than underestimate them. After all, the success of your construction project depends on it!
