Home Gas Powered Generator Prices

Most of us take electricity for granted in our day to day lives - until we lose it. It only takes one power outage to remind us how much we depend on conveniences like heating, air conditioning, lighting, and refrigeration.

Until just a few years ago, it was unusual for a homeowner to buy a generator. But due to an increase in extended power outages from hurricanes, wind storms, ice storms and other natural disasters, generators are becoming more and more common. An investment of a few thousand dollars provides peace of mind that when the lights go out everywhere around you, you'll be living in comfort.

About Gas Powered Home Generators

All generators, large and small, are powered by some form of gas. They can run on gasoline, diesel fuel, natural gas or propane.

There are two basic types of home generators:

  • Portable generators are designed to keep a few small appliances running for a short period of time. They're powered by gasoline or diesel fuel and need to be refueled every few hours. They're not sufficient for powering home heating systems or major appliances.

  • Standby generators are installed as a permanent fixture in the home. They're hardwired into your electrical system to turn on automatically when the power goes out. Smaller standby generators power just the essential circuits in your home while larger models can power the entire home. Standby generators typically run on propane or natural gas.

Gas Powered Home Generator Average Costs

Portable home generators are far less expensive than standby home generators. They start at about $500 for a basic model with less than one kilowatt of power and run up to $2,000 or more for durable, contractor-grade models that reach 15 kilowatts.

Standby generators start at around $1,500 and can run as high as $15,000, depending on the amount of power they provide.

  • Essential circuit generators typically run $1,500 to $4,000. They can power 8 to 16 circuits in your house so you can keep critical appliances running.
  • Smart circuit generators power most of the home (and potentially the entire home if you limit your electricity use). They typically have 15 to 20 kilowatts of power and cost $4,000 to $8,000. Most home generators fall in this price range.
  • Whole house generators, which provide 22 to 48 kilowatts of power, are the most expensive. They cost $8,000 to $15,000.

If you're planning to purchase a standby home generator, don't forget to factor in the cost of delivery, setup and installation. You'll need to hire an electrician to wire the generator, and the gas company will need to connect the generator to a propane or natural gas line. Total costs for delivery, installation, and setup are often about one-third of the price of the generator.
