Generac Commercial Generators

When the power fails, a commercial generator keeps your business open without missing a beat. It connects to your building’s electrical system through an automatic transfer switch and runs on natural gas or diesel, delivering reliable power to your lights, refrigeration, and equipment stay on through an outage. Anderson Power Services provides turnkey commercial generator solutions, including sales, installation, maintenance, and repair by factory-trained technicians, with power output matched to your commercial application.

As a veteran-founded company with local offices across Georgia, South Carolina, Alabama, and Florida, we understand the storm risks, permitting rules, and power needs unique to each market we serve.

Why Your Business Needs a Commercial Generator

A power outage does not wait for a good time. A voltage dip during a storm or a period of peak demand on the grid can corrupt sensitive electronics, from point-of-sale terminals to server hardware, long before the lights ever go out. A commercial standby generator gives your facility uninterrupted operation through both.

For hospitals and other facilities where backup power is required by code, a commercial standby generator is essential, and NFPA 110 sets the terms: how quickly power has to return, how long the system has to run without refueling, and how often it gets tested. Even when backup power is not required, it helps businesses avoid costly downtime and continue operating during unexpected outages. Wired into your building and fueled by natural gas or diesel, it powers back on within seconds through an automatic transfer switch, powering critical systems such as HVAC, servers, security systems, communications, production equipment, and lighting. No one has to be on site for it to run.

Our Services

Emergency Power Solutions

Severe weather or an overloaded grid can knock out a building with almost no warning, and crews from the power company may need days to bring power back. A commercial backup generator keeps your operation running in seconds if the grid fails, helping minimize downtime, protect productivity, and reduce costly business interruptions.

Full-Service Installation

Our crew manages the entire generator installation for your business. We match the system to your load, placing the unit and wiring the automatic transfer switch into your panel. Whether you’re purchasing a new commercial generator or need installation for an existing unit, our experienced team manages every step of the process.

Maintenance and Service

A generator is only worth having if it starts the moment you need it. Our factory-trained technicians provide preventative maintenance, diagnostics, and repairs for Generac, Kohler, and other leading generator brands. Routine service on a Generac or Kohler generator is what turns a unit sitting on a pad into peace of mind.

What to Expect From Installation

A commercial installation ties into your gas and electrical systems and has to clear local codes, so it should be left to licensed professionals. Some buildings, like healthcare facilities, carry extra standby power requirements that we account for from the start. Anderson Power Services manages every step with factory-trained technicians and licensed electricians on a timeline that depends on permit turnaround and any utility coordination. We also have financing available if you want to spread out the project cost.

Free On-Site Consultation

We look over your panel, your power requirements, and your load, then size the generator to match. Large-scale operations may need more than one generator set working in parallel.

Engineering

Design begins here. We run the load calculations, confirm the fuel supply and electrical distribution, and specify the generator and transfer equipment your building actually needs before anything is ordered.

Permitting

We file the necessary permits and schedule the inspection so the system meets local codes.

Installation

We position the generator, hook up the fuel, and connect the automatic transfer switch to your panel.

Commercial Generator FAQs

Every commercial generator project is priced individually, so we give you a quote rather than a fixed sticker price. The total depends on the unit you choose, your site, the automatic transfer switch, fuel and electrical connections, and permitting. Schedule a free on-site consultation, and we’ll evaluate your facility, determine your power requirements, and provide a customized proposal. Flexible financing options are available.

Yes. Our factory trained technicians service and maintain commercial generators from Generac, Kohler, and many other leading manufacturers, even if your system was installed by another company. We offer preventative maintenance, repairs, inspections, and emergency service to help keep your backup power system operating reliably.

Any operation where losing power means losing money, safety, or compliance. That often includes Medical facilities, manufacturing plants, restaurants, grocery stores, office buildings, schools, municipal facilities, hospitality properties, industrial facilities, and data centers. For hospitals and hotels, backup power is often required by code. If losing power would interrupt operations, impact customer service, damage inventory, or create safety concerns, a commercial standby generator is a smart investment.

We offer a wide range of commercial standby generators from leading manufacturers. During your consultation, our team performs a load analysis to recommend the right generator size based on your facility’s power requirements, operations, and future growth.

Most commercial units burn natural gas or diesel. A generator tied to a natural gas line keeps running for as long as the utility delivers fuel. A diesel generator draws from its fuel tank, so its run time tracks with tank size and how heavy a load you are carrying. Our team will help determine which fuel source is the best fit based on your facility, operational requirements, fuel availability, and local regulations.

Commercial generator installations must comply with applicable local building, electrical, and fuel gas codes. Depending on your facility, additional requirements such as NFPA standards may also apply. Our team manages the permitting process and coordinates inspections as part of the installation.

Once the consultation and permitting wrap up, the timeline hinges on the size of the system, how fast your jurisdiction issues permits, and whether the utility has to coordinate the gas or electrical connection. We hand you a firm schedule after we scope your site.

A commercial standby generator needs servicing on a set schedule. Routine maintenance includes oil and filter changes, battery inspections, coolant checks (when applicable), load testing, and a comprehensive system inspection. Our service plans add 24/7 remote monitoring to catch trouble early, and staying on the manufacturer’s maintenance schedule also helps keep your warranty intact.

Warranty coverage varies by manufacturer and generator model. During your consultation, we’ll review the warranty options available for your selected system and explain any maintenance requirements needed to maintain coverage.
