Orange County Commercial Generator Experts

Orange County businesses run on steady electric power, and a single outage can stall production, spoil inventory, or close a job site. Duthie Power has sold, rented, serviced, and repaired commercial generators for more than 60 years, making us an industry leader in standby power across Southern California. Our crews cover sites throughout Anaheim, Santa Ana, Irvine, Huntington Beach, and the surrounding areas, delivering backup power to manufacturing plants, data centers, hospitals, and other commercial operations. We stay with your standby generator for its entire service life, handling sizing, professional installation, ongoing maintenance, and the power systems that tie it all together.

What We Do

We work with Orange County operations managers, facility engineers, and plant teams who need full-service backup power they can count on. Our technicians know every make, model, and fuel type, so a single standby generator gets the same care as an industrial generator fleet spread across a multi-building campus.

  • Electric Generator Sales in Orange County

    Our sales engineers spec and install Generac generators alongside units from Caterpillar, Cummins, Blue Star, Gillette, and Kohler, handling sizing, installation site prep, and the necessary electrical connections.

  • Generator Repair and Diagnostics

    Our factory-trained, EGSA-certified technicians diagnose and repair generators, transfer switches, control panels, and Emergency Power Supply Systems across every major brand.

  • Commercial Generator Rentals

    We rent commercial units between 22KW and 1,500KW for short-term jobs, scheduled shutdowns, and long outages, paired with the fuel tanks, distribution panels, transfer switches, and cabling that complete the setup.

  • Generator Maintenance Programs

    A maintenance plan covers inspections, oil changes, diesel fuel polishing, battery testing, and diagnostics. This catches wear on your backup generator before it becomes an emergency repair and keeps your warranty coverage accurate.

  • 24/7 Emergency Service

    We staff our dispatch line 24/7, every day of the year, so an Orange County technician can restore emergency power the moment a generator fails or grid power drops in a natural disaster.

  • Automatic Transfer Switch Service

    Your automatic transfer switch flips the load between utility power and your standby generator. We keep every make and model of ATS reliable with contact cleaning, lubrication, calibration, testing, and repairs for the faults behind failed-start events.

Industries We Serve Across Orange County

Duthie Power keeps Orange County’s key commercial and industrial operations running, including logistics and warehousing, manufacturing, cold storage, data centers, hospitals, and schools. Distribution centers count on us to keep conveyors, refrigeration, and loading docks online through any dip in the electricity supply. Hospitals trust us with the life-safety gear and medical equipment that can never go dark. Our sales engineers and technicians stay current on the code requirements, uptime demands, and South Coast AQMD permitting that apply across Orange County.

Plan Ahead to Prevent Downtime

The best backup power is the kind already installed, maintained, and tested before the lights flicker. Size a standby generator correctly, wire it to an automatic transfer switch, and it carries the load within seconds of a grid failure, keeping your priority systems alive while utility power is out and lowering the risks of a costly shutdown. Steady service from our Orange County team keeps the whole package healthy, the transfer switch, controller, fuel system, and alternator included.

Frequently Asked Questions

Hard starts, rough running, warning lights on the controller, oil or coolant leaks, and a unit that quits under load all point to a problem. Catching them early lets our technicians fix small faults before they leave you without backup power during an outage.

Most commercial sites run a monthly exercise cycle plus an annual load bank test, and facilities under NFPA 110, like hospitals, follow tighter schedules. We handle the testing and hand you the documentation your compliance audits call for.

Diesel, natural gas, and LP vapor each have a place. Diesel keeps plenty of power on site for long outages, natural gas draws from the utility line, so there is no tank to refill, and LP vapor fits sites where gas service is limited. Our sales engineers help you weigh runtime, fuel access, and budget before you buy.

We install new commercial generators to NFPA standards and coordinate the electrical work with your electrical contractor so the unit comes online safely. We can pull permits on our behalf during a new install. We do not run emissions testing, so plan to arrange that separately if your site requires it.

Yes. If your generator is down for a major repair, we can set up a commercial rental between 22KW and 1,500KW to carry your load, then pull it once your unit is back online. That way, a repair never turns into a full power outage for your operation.
