Who Needs a Standby Generator?
Any business where a power outage means lost revenue, spoiled inventory, or safety risks. Hospitals, data centers, manufacturing plants, restaurants, grocery stores, assisted living facilities, gas stations, water treatment plants, and commercial buildings all depend on standby power. Homeowners who want whole-house backup during storms also benefit from residential generator installation.

Our Generator Installation Process
Load Analysis & Sizing
We calculate your facility's critical electrical load to determine the right generator size. Oversizing wastes money; undersizing leaves you exposed.
Site Planning & Permitting
We handle the concrete pad, fuel connections, setback requirements, and all Louisville Metro permits so you don't have to.
Installation & Wiring
Our licensed electricians install the generator, automatic transfer switch, and all electrical connections to your building's main panel.
Testing & Commissioning
We simulate a power outage to verify automatic start-up, load transfer, and shut-down. We train you on operation and set up a maintenance schedule.
Generator Installation Cost Factors
Standby generator costs in Louisville depend on several factors:
- Generator size (kW rating) — residential 22kW units start around $6,000-$8,000 installed; commercial 100kW+ units range from $30,000-$150,000+
- Fuel type — natural gas, propane, or diesel
- Automatic transfer switch type and amperage
- Distance from fuel source and main electrical panel
- Concrete pad and site preparation needs
- Permit and inspection fees
- Ongoing maintenance plan selection
Generac Authorized Dealer — Sizing, Install and Startup
Hadley Energy Solutions is an authorized Generac dealer and factory-trained on the Guardian, Protector and Industrial series, which means we can perform warranty service other contractors cannot. Every install is turn-key and performed by a Kentucky Master Electrician (ME64500): load calculation and sizing, concrete pad, natural-gas line from your meter, automatic transfer switch tied into the service entrance, Louisville Metro or county permit, final inspection, commissioning and Generac Mobile Link Wi-Fi monitoring set up on your phone before we leave at no extra cost. Louisville sees an average of four to six multi-hour LG&E outages a year from ice storms, summer derechos and aging infrastructure. A correctly sized standby generator runs on your existing natural gas line, starts automatically within about ten seconds of an outage, and carries the whole house — HVAC, refrigerator, sump pump, well pump, lights and outlets — until utility power returns.
Honest Sizing: Whole-Home and Commercial
Sizing is where most generator quotes go wrong. Oversizing wastes thousands of dollars up front; undersizing trips the unit during peak load. We do a free on-site load calculation and quote the size your building actually needs — if a 14kW handles your home, we will not push a 22kW at you. Residential whole-home units run 10kW to 26kW, with 14kW the most common choice for Louisville homes and 26kW covering large homes with no load management at all. Commercial standby ranges from 35kW to 150kW-plus in air- and liquid-cooled configurations for offices, restaurants, medical facilities, retail and warehouses, single- or three-phase, with NEC-compliant transfer switching. Most Louisville home installs go from quote to commissioning in four to eight weeks including permit; commercial schedules vary with equipment lead times.
Service, Maintenance and Local Support
We service Generac, Kohler, Briggs & Stratton and Cummins generators, including annual maintenance plans, oil and filter changes, battery replacement, load-bank checks and emergency repair when a unit fails to transfer during an outage. Our service technicians are based in Hillview, Kentucky, roughly thirty minutes from most of the Louisville metro — when your generator throws an alarm you reach a local shop, not a national 800 number. Annual maintenance plans run $295 to $495 and cover oil, filters, battery testing and a full inspection, which also keeps manufacturer warranty coverage intact.

Standby Generator Installation (Generac) FAQs
Are you an authorized Generac dealer in Louisville?
Yes. Hadley Energy Solutions is an authorized Generac dealer, factory-trained on the Guardian, Protector and Industrial series — including warranty service many contractors cannot perform. We also service Kohler, Briggs & Stratton and Cummins equipment.
What is included in a turn-key generator install price?
Everything: the generator, the automatic transfer switch, the concrete pad, the natural-gas hookup, the permit and inspection, commissioning, and Generac Mobile Link Wi-Fi monitoring setup. There are no surprise add-ons after the quote.
What size whole-home generator do I need in Louisville?
Most Louisville homes land on a 14kW unit. Homes under about 1,800 sq ft with basic loads often work at 10kW, two-zone HVAC and heavy loads usually need 18–22kW, and large homes that want no load management at all take 26kW. We run a free on-site load calculation rather than guessing.
Will a standby generator run my air conditioning?
Yes, when it is sized for it. A properly sized natural-gas standby carries central AC, the furnace blower, refrigerator, sump pump, well pump, lights and outlets, and it transfers automatically within about ten seconds of an outage.
Do you offer generator maintenance plans?
Yes. Annual maintenance plans run $295–$495 and include oil and filter changes, battery testing and a full inspection. Regular maintenance is also required by most manufacturers to keep the warranty valid.

Residential Generac generators typically cost $6,000 to $15,000 installed in Louisville, depending on size. Commercial generators range from $30,000 to $150,000+. Hadley Energy Solutions provides free on-site estimates. Call (502) 921-3777.
How long does generator installation take?
Residential installations typically take 1-2 days. Commercial projects take 1-4 weeks depending on size and complexity. We handle all permits, concrete work, fuel connections, and electrical wiring.
Do I need a permit for a generator in Louisville?
Yes. Louisville Metro requires electrical permits for generator installations. Hadley Energy Solutions handles all permit applications and inspections as part of our installation service.
How often does a standby generator need maintenance?
We recommend maintenance every 6-12 months, including oil and filter changes, battery testing, coolant checks, and load bank testing. Our PM programs include generator maintenance for commercial customers.
What size generator do I need for my business?
Generator size depends on your critical electrical load. A small office might need 20-50 kW, while a manufacturing plant could need 500 kW or more. We perform a detailed load analysis to determine the right size — no guessing.
