What We Offer

At Duthie Power Services, we provide complete generator sales and support backed by over 60 years of industry expertise and a commitment to keeping Southern California businesses operational.

Custom-Ordered Generators for Every Application

We don’t keep new generators in stock, and that’s by design. We custom-order every generator set to match your specific requirements, with access to commercial generators for sale from all leading brands, including Caterpillar, Cummins, Blue Star, Generac, Gillette and Kohler. Generator sizes range from 2,000 KW industrial units to portable generators, and our sales engineers help you find the right balance of power rating, fuel type, and price.

Generator Installation and Ongoing Maintenance

Duthie Power’s EGSA-certified union technicians handle professional installation and provide ongoing maintenance to keep your equipment compliant with local and state regulations. Our team also offers preventative maintenance plans, diagnostics, and 24/7/365 emergency repair to keep your backup power system running at peak performance. If your generator needs repair services or replacement parts, our service team will provide a quote that meets your approval before any work begins.

Frequently Asked Questions

We sell all major types of generators, including industrial diesel generators, stationary generators, and portable generators. Since we custom-order from a variety of manufacturers, you have access to different brands and every generator size from portable units up to 2,000 KW.

Generator sizing depends on your facility’s total power requirements, including all electrical equipment and systems that need to stay online during a power outage. Our sales engineers will assess your load demands, factor in your fuel type preference, and recommend a generator with the appropriate power rating for your operation.

A diesel generator refers to the fuel type and engine powering the unit, while a standby generator describes how the unit is used. Many standby generators run on diesel engines because of their high power output and reliability under heavy loads. A standby generator is permanently installed at your facility and activates automatically during a power outage, while a portable diesel generator can be moved between locations as needed. Our team can help you determine which setup best fits your operation.

Absolutely. Our EGSA-certified union technicians provide full installation services, preventative maintenance plans, diagnostics, and 24/7/365 emergency repair. We’ll keep your generator compliant with all regulations and ready to perform whenever you need it.

Yes. We offer portable generators that work well for construction sites, temporary events, and remote locations. If your need is short-term, we also offer commercial generator rentals as an alternative to purchasing.
