Who Rents Generators – and Why?
Businesses across every major industry rent generators for different reasons—but speed, reliability, and flexibility are always at the center of it. Here are some of the most common applications we support:
Construction & Contracting
Most job sites don’t have permanent power. We provide rugged, trailer-mounted diesel units to keep tools, lighting, and trailers powered up—whether you’re framing houses or building highways.
Events & Entertainment
Concerts, festivals, weddings, sporting events—when your event is off the grid, portable generators keep the show going. Our units are quiet, clean, and easy to set up.
Oil & Gas | Industrial Operations
Remote locations and high power demands are standard in oilfields and industrial facilities. Our containerized and high-kW generators are built for durability in harsh environments.
Healthcare & Hospitals
Downtime isn’t an option. We support hospitals and mobile healthcare units with emergency backup power during maintenance windows, outages, or crisis response.
Utilities & Infrastructure
From planned grid upgrades to storm recovery, utility companies count on us for temporary power that keeps neighborhoods and infrastructure running.
Data Centers & IT
Temporary units bridge the gap during expansions or equipment upgrades, ensuring 24/7 uptime for mission-critical systems.
No matter the use case, we help teams stay powered, productive, and prepared. And because every project is different, we tailor the equipment and delivery to fit your exact specs.

Renting vs. Buying a Generator: What’s Right for You?
For many of our commercial and industrial customers, the question often comes down to this—should you rent a generator or invest in one long-term? While buying might make sense in certain situations, renting offers some real advantages—especially when time, budget, or flexibility matter most. Here’s why renting a generator might be the smarter move:

You don’t just get a generator—you get our team. From installation to load testing, we make sure every unit we send out is ready to perform. And if you need help onsite, we’re just a phone call away. - No Surprise Costs
