Commercial Generator FAQ

Answers to common questions about commercial and industrial backup power solutions.

What size commercial generator does my business need?

The right size depends on your facility’s electrical load, including HVAC, lighting, refrigeration, computers, and critical equipment. We perform a detailed load analysis during a site assessment to recommend the optimal generator size. Small businesses typically need 22–38kW, mid-size facilities 48–80kW, and large operations 100kW or more.

How much does a commercial generator cost?

Commercial generator costs vary widely based on power output, fuel type, and installation complexity. Small commercial units (22–38kW) start around $8,000–$15,000 for equipment alone. Mid-range (48–80kW) typically runs $15,000–$35,000, and large commercial units (100kW+) range from $35,000 to over $100,000. Installation, concrete pads, fuel connections, and transfer switches are additional. We provide detailed, transparent quotes.

What fuel type is best for commercial generators?

Natural gas is popular for businesses with existing gas service, as it provides an unlimited fuel supply with no storage tank. Propane (LP) works well in rural areas without natural gas infrastructure. Diesel is preferred for large industrial applications due to fuel efficiency and high power output. Bi-fuel options combine diesel with natural gas for extended run times. We’ll recommend the best option based on your location and needs.

How long does commercial installation take?

Commercial installations typically take two to six weeks from contract to commissioning, depending on the project scope. This includes site assessment, engineering, permitting, concrete pad preparation, fuel system installation, generator and transfer switch installation, and final commissioning with load testing.

What maintenance is required for commercial generators?

Commercial generators require regular maintenance, including oil and filter changes, coolant system checks, battery testing, fuel system inspection, and load bank testing. We offer customized maintenance agreements to keep your generator ready. Most commercial units run automated weekly self-tests, and we recommend professional service every six to 12 months.

What is the difference between standby and prime power?

Standby power generators activate automatically during utility outages and are designed for emergency backup. Prime power generators run continuously as the primary power source, a common arrangement in remote locations without reliable grid access. Most commercial applications use a standby configuration, while mining, agricultural, and remote industrial sites often need prime-rated units.

Can generators be paralleled to increase power output?

Yes, Generac industrial generators can be paralleled to combine multiple units for greater total output and redundancy. Paralleling is ideal for facilities that need scalable power, as you can add capacity as your business grows. It also provides N+1 redundancy so critical loads stay powered even if one unit is offline for maintenance.
