If you're a construction contractor, there's a good chance you'll need to rent a generator at some point. Generators provide electricity for tools, equipment and lighting at remote sites that don't have access to the power grid. They can also provide emergency backup power when an outage occurs, minimizing the risk of costly downtime.
When you're looking for the best job site generator for your construction projects, you'll discover that they come in a wide variety of sizes, configurations and power output capacities. It's important to select a model that provides sufficient power to keep your site running, but not so much that you end up wasting electricity — and money.
As a rule, you'll want a generator that provides enough power for your site when operating at 70-90% capacity. A generator that runs at less than 50% of its capacity creates a situation called "wet stacking," which significantly reduces the unit's operating efficiency.
Taking the following factors into account can help you determine the proper size and output capacity for your generator rental:
A simple way to calculate the best job site generator size for you is to add up the wattages of all the equipment and tools that require electrical power. You can then compare this total with the wattage of the generators that are available for rent. Be sure to choose a model that offers a little extra capacity to account for power surges and the possible addition of more equipment during the project.
A commercial generator sizing calculator gives you an easier way to determine the appropriate size for your units. Start by making a list of all the tools and machinery (air compressors, saws, jackhammers, portable office and computer equipment, etc.) that may require electrical power at your construction sites. You can then check the starting and running wattage for each, which is inscribed on the equipment.
Finally, calculate your total power requirement by adding all the kW or KVA amounts. The power capacity of the generator you choose should exceed this figure by 10-20% to give you a margin for error.
Another factor to consider when choosing a generator for your job site is the fuel source. Both diesel and natural gas-powered models are available, and each offers certain advantages.
Benefits of diesel generators include:
Some advantages offered by natural gas generators include:
