"Generators of Maine just completed the installation of a 14kw generator with parallel transfer switches, to protect 2 separate metered panels at a rental property that I own. I didn't even know that this was possible, until Doug Sawyer suggested it. The incremental cost of protecting the additional panel with the parallel transfer switch arrangement was a fraction the cost of an additional generator and transfer switch. Throughout the job, Doug and his crew were awesome. I am a terrible snoop who enjoys technology, so I hung around just watching and learning. They didn't seem to mind my presence and were friendly and informative through out the install. Every aspect of the job was 100% top-notch. Doug also managed to under bid his nearest competitor on every component and aspect of the job, including the annual maintenance contract, which I deemed to be worth the $$$. I highly recommend Generators of Maine."

"Gracen is excellent! I needed a transfer switch to run my generator from the electrical panel. From first quote to job done, Gracen kept in touch. He does good honest work and explains everything heâ s done. Heck, he even put up with my dog barking the whole time he was over lol. When he was done with the job, he helped me go through everything and in detail. Recommend highly"

"Kevin called me the same day I posted the pro request. I scheduled him to come by to do a quote two days later and hired him at that point. Kevin replaced a scary exterior electrical outlet and power cord that powers a pool pump. The power cord was coming out of the ground and arcing and the old outlet was melted around a socket. Not good. Kevin fixed it right up and replaced and greatly improved the whole set up, including installing an exterior outlet and switch that are both protected by the weather. Very impressed and will hire Kevin again."

Generator Install questions, answered by experts

Generators run on a variety of fuel types, ranging from natural gas to solar power. Keep in mind that fuel costs varying by type:

  • Natural gas: $2,000–$21,000 per year 

  • Liquid propane: $2,000–$21,000 per year

  • Diesel: $3,000–$20,000 per year

  • Gasoline: $500–$3,000 per year

  • Solar generator: $2,000–$25,000 per unit

  • Battery backup: $10,000–$25,000 per unit

The cost to install a whole-house generator averages $5,200, with a typical price range of $1,500 to $8,900. However, total costs can vary from $400 for a small portable unit to over $18,000 for a large-capacity system. The most significant cost factor is the generator's size and capacity, but other variables include the brand, fuel type, and labor for assembly and installation.

Generator costs can be broken down by type:

  • Portable or Emergency Backup Generators (1kW–7.5kW): $500 to $2,000

  • Partial-Home Generators (9kW–20kW): $2,000 to $6,500

  • Whole-House Generators (22kW–48kW): $5,000 to $18,000

To avoid paying for more power than you need, consider hiring an electrician to calculate the electrical load for your essential appliances. It is also recommended to get at least three quotes to find the best deal for your specific needs and budget.

In many cases, yes. There are models called dual-fuel generators and fuel switches, but only between certain types of fuel. For example, with the right setup you can convert a generator from natural gas to propane. Some allow switching between diesel and gasoline. There are even tri-fuel generators available in some cases, which adds a large layer of security if you are worried about fuel availability in times of crisis. Always check your generator capabilities and manual instructions before trying to switch fuels. Some generators can use another fuel but may need a fuel conversion kit to prep them first.

Costs depend on generator type, labor, and additional wiring or transfer switch requirements.

To determine the right size generator for your house, you should calculate the total wattage of the appliances and devices you want to power during an outage. List all essential items, note their start-up wattages, and add them together.

Here are some typical wattage requirements for common appliances:

  • Refrigerator: 600 watts

  • Large dehumidifier: 700 watts

  • Large window air conditioner: 1,400 watts

  • Water heater: 3,000 to 4,500 watts

  • Electric furnace: 5,000 to 25,000 watts

A 7,500-watt generator might be sufficient for essentials like a refrigerator, freezer, well pump, and lighting circuits. However, for high-demand items like a water heater or furnace, a whole-home generator is a better choice. A portable generator may be enough if you only need to power a few critical items.

While home square footage can offer a rough estimate, it is not always a reliable indicator. For reference, here are some typical generator sizes based on square footage:

  • 1,000 sq ft: 6–9 kW

  • 1,500 sq ft: 7–10 kW

  • 2,000 sq ft: 10–14 kW

  • 2,500 sq ft: 12–16 kW

  • 3,000 sq ft: 16–20 kW+

For the most accurate sizing, consult a professional who can calculate your home's peak and average power consumption and recommend the optimal generator.
