Homeowners considering a backup generator almost always start with the same three questions: what does it cost, what size do I need, and what is actually involved in putting one in? A whole-house standby generator in Northwest Arkansas typically runs somewhere between $7,000 and $15,000 fully installed, and where a given home lands in that range depends on the size of the unit, the fuel source, and the work required to connect it.

Here is a straight answer to all three questions.

What it costs

Most whole-house standby generator projects land between $7,000 and $15,000 installed, with the generator unit itself making up part of that and the installation labor and materials making up the rest. A useful rule of thumb in the industry is that installation costs often roughly approximate the equipment cost. A smaller unit covering essential circuits sits at the lower end. A large unit running the whole home, including central air, sits at the upper end.

Portable generators are a much cheaper option, generally a few hundred to a couple thousand dollars, but they cover only a few circuits, require manual setup, and do not connect to the home the way a permanent standby unit does. For homeowners who want the power to come on automatically during an outage without anyone touching anything, a standby generator is the system that does that.

What size do you need?

Sizing is where homeowners most often go wrong, in both directions. Too small, and it cannot carry what you need during an outage. Too large and you have paid for capacity you will never use. The right size starts with a simple exercise: list the appliances and systems you actually want running during an outage, separating the must-haves from the nice-to-haves.

HVAC, refrigerator, freezer, well or sump pump, medical equipment, internet, and some lighting are the typical must-haves. A 20kW generator is a popular choice that handles most of a typical home, but the correct number for your home comes from an actual load calculation, not a guess. That is part of what a proper assessment determines before any equipment is ordered.

Natural gas or propane

Standby generators in this area run on either natural gas or propane, and which one makes sense depends on what your property already has.

A natural gas generator ties into the home’s gas line and runs indefinitely as long as the utility keeps supplying gas, which is an advantage during long outages. A propane generator needs a tank on the property, and its runtime is limited by how much propane is in that tank. Homes without natural gas service, common on the more rural edges of the area, typically go with propane. Both are solid options; the right one comes down to what is available where you live.

What the installation involves

A standby generator is not a plug-in appliance. It is a permanent installation that involves several trades, and the details are what drive the cost up or down.

The generator connects to the home through a transfer switch, which is the component that safely moves the home from utility power to generator power when an outage hits. An automatic transfer switch does this without the homeowner doing anything, which is the entire point of a standby system. The unit sits on a pad outside, a set distance from doors and windows, and gets connected to both the electrical panel and the fuel source.

Placement matters for cost. A generator near both the electrical panel and the gas meter is the most economical to install. Long electrical runs, long gas line runs, trenching, or a panel that needs work first all add to the total. Permits are also part of the process, which a licensed electrician handles as part of the job.

Because so much of the cost depends on your specific property, the panel, the fuel situation, and the placement, a real generator quote comes after a look at the home.
