Power outages cost money. We size, install, and maintain commercial standby generators with automatic transfer switches — keeping your critical operations running through any outage.
For a business, a power outage means revenue lost, equipment damaged, food spoiled, customers turned away, employees standing idle. A commercial standby generator means your operation keeps running — automatically, within seconds of grid failure. ABC Electric Inc. installs and services commercial generators across central Kentucky.
Commercial generator installation is more involved than residential. Three-phase generators (208V or 480V), larger amperage transfer switches, fuel coordination (natural gas, LP, or diesel), more rigorous code requirements, and often a need to prioritize critical loads on a separate emergency panel. We handle all of this with the experience of two decades of commercial generator work.
We size generators carefully — oversizing wastes money on equipment, fuel, and maintenance. Undersizing means the generator fails when you need it most. We do detailed load calculations with you, decide what is critical (refrigeration, POS, lighting, security) versus nice-to-have (full HVAC, all general outlets), and recommend a generator sized for the actual mission. Then we handle installation, commissioning, and ongoing maintenance.
Here is what is typically included when we handle this service for you.
208V and 480V three-phase commercial generators. 22-500+ kW range.
Auto transition from utility to generator. Critical load segregation if needed.
Detailed load calculations. Right-sized for your operation, not oversold.
Natural gas, LP, or diesel. Tank sizing, fuel line work, supplier coordination.
Full load testing before handover. Documentation for warranty and code compliance.
Annual service, fuel system maintenance, transfer switch testing, load bank testing.
We offer commercial standby generators across all five of our service areas. Click your city for local information.
Anderson County coverage. Our home base — the fastest response times in the area.
Lawrenceburg →Franklin County coverage. Kentucky's capital city. Historic and modern homes alike.
Frankfort →Woodford County coverage. Horse country, downtown, and surrounding communities.
Versailles →Fayette County coverage. Kentucky's second-largest city — full Bluegrass-area service.
Lexington →Jefferson County coverage. Kentucky's largest city — full Derby City service.
Louisville →Depends on what loads need to stay live during an outage. For most small commercial (restaurant, retail, small office), 50-100 kW handles essentials. For full operations or mid-sized buildings, 150-300 kW is common. We do a load study during the estimate.
Most of the work happens outdoors and at the panel/transfer switch — minimal interior disruption. The actual cutover from utility-only to generator-protected typically takes one short outage window, scheduled at your convenience.
Yes — commercial generator installations require permits. We handle the permit process, coordinate inspections, and ensure code compliance for the installation, fuel system, and exhaust.
Generators should be exercised weekly (most do this automatically) and serviced annually. Critical-mission generators may need more frequent testing. We offer service contracts that cover all manufacturer-recommended maintenance.
