If you’ve lived through a West Kentucky ice storm — or the windstorms that roll across the lakes in summer — you know the power can go out for hours or days at the worst possible time. A standby generator promises to take that worry off the table: when the grid drops, your generator starts automatically and keeps your home running. But is it worth the cost? Let’s break it down honestly.
As an authorized Generac Select Dealer, we install these systems every week, and we’ll tell you straight when a standby generator makes sense and when it doesn’t.
How a standby generator actually works
Unlike a portable generator you wheel out and fill with gas, a standby unit is permanently installed outside your home — much like an AC condenser. It connects to your natural gas or propane line and to an automatic transfer switch at your panel.
When it senses an outage, it starts within seconds, disconnects you safely from the grid, and powers your home. When utility power returns, it switches back and shuts off. You don’t have to be home, awake, or even aware of the outage.
Why West Kentucky homes are good candidates
A few local realities make standby generators especially valuable here:
- Ice and wind storms regularly cause multi-day outages across rural Calloway, Marshall, and surrounding counties.
- Lake homes and properties on long rural feeders are often last to be restored.
- Many homes run on well water and septic pumps — no power means no running water.
- Frozen pipes, spoiled food, and a dead sump pump can cost more than the generator over a few bad winters.
What does a Generac generator cost?
Pricing depends on size and your home’s layout, but most whole-home installations land in the $8,000 to $16,000 range, including the unit, transfer switch, gas hookup, electrical work, concrete pad, permits, and labor. The generator itself is only part of that — distance from your gas meter and panel, trenching, and load management all affect the final number.
Smaller, essentials-only systems (refrigerator, well pump, furnace, a few circuits) cost less, while true whole-home backup for a large lake house costs more. The right size depends on what you actually need to keep running.
Is it worth it for you?
A standby generator is worth it if you value uninterrupted power for medical equipment, a home business, well water, or simply peace of mind during long outages — and if you plan to stay in your home long enough to enjoy it. It also tends to add resale appeal in storm-prone areas.
If you only lose power for an hour or two a couple times a year, a portable generator or battery backup may serve you fine for less money. We’d rather help you make the right call than oversell you.

Frequently Asked Questions
How much does a whole-home Generac generator cost installed?+
Most whole-home standby generator installations run between $8,000 and $16,000, including the unit, transfer switch, gas connection, pad, permits, and labor. Essentials-only systems cost less. We provide an exact quote after sizing your home’s needs.
Does a standby generator run on natural gas or propane?+
Both options are available. If you have natural gas service, the generator can tie directly into it for unlimited runtime. Homes without gas service typically use a propane tank. We help you choose based on what fuel you already have on site.
How often does a standby generator need maintenance?+
Plan on annual maintenance — oil and filter changes, battery checks, and a system test — similar to servicing a small engine. The unit also runs a brief self-test weekly. We offer maintenance plans to keep your warranty valid and your generator ready.
