How much is a generator to power an entire house?

This price includes a 7.5-10kw (kilowatt) generator that runs on natural gas, electrical connections include an automatic power transfer switch and automatic start functionality when power goes out, as well as the installation of a natural gas line to power the generator and provide the power needed to power your home. Keep in mind that a backup generator can be connected to all the electrical circuits in your home or just to some “essential circuits”. Formerly limited to hospitals and government buildings, large generators are now an available option for many homeowners. A portable generator is a device that provides temporary power during an outage or for outdoor recreational events, such as tailgates.

Connecting just a few essential circuits, or “part house generator,” can be an effective means of providing power to electrical circuits important to you while saving on overall project costs. For a standby generator that powers your entire home, you'll need an electrician to install a transfer switch, which connects the generator to your home's circuit board and allows you to supply power through existing circuits. You can then compare what we've discovered about backup generator installation costs with information from other sites and with the actual costs presented by homeowners. Generators are sized in kW or kilowatts, so a 10 kW generator will produce 10 kilowatts or 10,000 watts of power.

So, if you want a portable generator, you'll need to decide which appliances are essential in a power outage and choose a model powerful enough to run them all simultaneously. Never, under any circumstances, operate a generator inside your home or garage, even with the doors and windows open. If your home is 2500 square feet or less, a 20 kW generator should fit your needs well, especially if you have gas heating and hot water. Gasoline generators tend to be the most economical because they are relatively well-established and common.

In fact, the savings of a single outage can more than recoup your investment in a domestic standby generator. While this is considerably more than what you would spend on candles, flashlights, batteries and a rope radio for emergencies, the benefits far outweigh the cost of the generator if you consider that food that can spoil in your refrigerator and freezer, have no heating, etc. If you work or run a business from home, the generator of the whole house can cause it to work again less than a minute after the power goes out.
