When power outages hit, whether from storms, grid issues, or unexpected failures, having a home generator can bring peace of mind and keep your family safe and comfortable.
But one of the most common questions we get is:
“How much does it cost to install a home generator?”
The answer depends on how much of your home you want to power and what level of convenience you’re looking for. Here’s a breakdown of the most common options and pricing considerations.
This is the most budget-friendly and flexible option. An interlock kit allows you to safely connect a portable generator to your home’s breaker panel. You choose which circuits to run by flipping breakers — like your fridge, lights, or outlets.
This setup requires manual operation during an outage but provides a safe and code-compliant way to power essentials.
🔧 Typical installation cost: $900 to $1,500 (not including the generator itself)
⚡ Best for: Homeowners who already own or plan to buy a portable generator and want a cost-effective solution for basic backup power.
A manual transfer switch gives you more control over which circuits receive power from your generator. It’s installed near your panel and allows you to switch between utility and generator power for specific circuits.
This is a step up from an interlock and offers slightly more convenience.
🔧 Typical installation cost: $1,500 to $2,500+
⚡ Best for: Homeowners wanting a semi-permanent solution without the full investment of an automatic standby system.
This is the gold standard for home backup power. A standby generator (like those from Generac or Kohler) is permanently installed outside your home and kicks on automatically when the power goes out.
It can power your entire home or just critical systems, depending on the generator size and installation.
🔧 Typical installation cost: $15,000 to $25,000+, depending on size, gas line requirements, and load coverage.
⚡ Best for: Homeowners wanting full, hands-free backup power for comfort, safety, or business needs during outages.
