How Much Does A Natural Gas Home Generator Cost?

If you don’t feel comfortable (or interested) in maintaining your generator, your dealer and/or installer may provide maintenance contracts ranging from one to ten years, with discounts for longer commitments. The cost of maintaining a 20-kW home standby generator is estimated to be roughly $500 per year. Service plans for commercial customers might cost anything from $1,0000 to $2,000+ per year. Heavy-duty commercial generators that experience dozens of hours of use per week, especially if they’re used for prime power, are best assigned to skilled maintenance workers.

What is the price of a whole-house natural gas generator?

Portable or standby whole-house generators are available. Portable whole-house generators can be moved around, whereas standby generators are fixed in one location. On average, a whole house generator costs between $1,000 and $6,000. Prices for whole-house generators might reach $10,000, but you don’t need to pay that much to obtain a good one. On the other hand, if you have the funds and want the finest of the best, a pricey standby generator may be the ideal option.

To power the essentials in a typical home, a 5,000-watt generator is required. Although not all portable generators are capable of handling such electrical load, many can. Portable generators usually have a power range of 3,000 to 8,500 watts and cost between $400 and $1,000. Some are available at a higher price and with more power.

A word of caution: Never use a portable generator indoors, in a garage, or in any other enclosed location. There is a risk of carbon monoxide poisoning if you do so. These generators must be placed at least 20 feet away from your home, with the exhaust directed away from any nearby structures, including residences.

Inverter generators are also portable, however they cost a little more than traditional portable generators. They usually cost between $500 and $4,000. Because inverter generators may not always function at full power, they are more expensive than regular portable generators. They change in response to the demands. Inverter generators are also less noisy and emit less pollutants than traditional portable generators. Despite the lower emissions, you must still observe the same safety precautions.

Regardless of the sort of portable generator you purchase, you must also get a canopy to protect it from the elements. In addition, the canopy must be compatible with the generator. When comparing pricing, remember to include this expense. A generator canopy could cost between $100 and $200.

Although some generators may run in tandem, it’s usually more cost-effective to acquire a generator with the full wattage you want. Consult the manufacturer to see if a model can be “parallel run” and, if so, which models. When it comes to parallel generators, they can usually only be securely paralleled with the same model. Parallel operation is usually possible with inverter generators.

Standby and Backup Generators

Standby and backup generators may appear to be the same thing, but they are not. When a power outage is detected, a backup home generator immediately begins and, once operational, reconnects you to utility power via an automatic transfer switch. A professional whole house generator installation is required to install standby home generators.

Most standby generators need to be exercised on a regular basis to keep in excellent working order. They oil the engine and do diagnostic checks for roughly 12 minutes. These generators have the ability to charge their own batteries as well. Propane and natural gas are two fuel options for standby generators. Check the model to see what kind of fuel it works with. Depending on the model, home standby generators can produce anywhere from 5,000 to 20,000 watts. A residential standby generator costs between $3,000 and $6,000 on average.

When there is a power outage, backup generators, on the other hand, must be manually started and stopped. Portable generators, for example, are backup generators. Some of them feature a button that allows you to start and stop them quickly. Others, like antique lawnmowers, feature a pull-crank handle. You can set up a portable generator on your own, but read the user handbook thoroughly first and carefully follow the instructions for your safety.

Small, Portable Home Generators

Small portable generators are typically used for camping, but they can also be used to power smartphones and computers. They have a power range of 900 to 2,000 watts. Small portable generators range in price from $130 to $400. If whole-house generators are out of your price range, a small portable generator can be useful to keep on hand in case of an emergency until you can afford a more powerful model.

Generac Prices

Generac is a well-known generator brand. The cost of a Generac home standby generator starts at $1,949. The Generac Mobile Link app allows you to keep an eye on your generator. You don’t have to manually refill these generators because they link to your home’s natural gas or LP (liquid petroleum) fuel source. Unlike a portable generator, a Generac standby generator does not require an extension cord to be run through your window or door.

Installation costs for this type of standby generators are determined by local building standards, generator size, and installation concerns. When your electric and gas meters are on the same side of your house, installation is less expensive.

Generac’s portable generators start at $439 and generate 3,300 watts. They have a higher output than standard portable generators. Portable Generac home generators include the following features:

Fuel tanks with a large capacity can hold more than 3.3 gallons. At 50% load, a 12-gallon tank gives 32.4 hours of runtime. One of the cheapest Generac models, the GP3300 49 ST, has a 3.3-gallon tank and generates 3,300 watts.

Electric start is a highly recommended feature that makes using a generator much easier. You want it to be possible for others in your family to start it. Pull-start versions necessitate a certain amount of arm strength, which not everyone possesses.

Another significant characteristic in a generator is low-oil-pressure shutdown, which protects it from damage when it runs out of oil. An hour meter keeps track of when your last maintenance check was performed. Idle control saves you money on gas and decreases generator noise.

Generators with a steel cradle are more robust, and having an integrated lifting eye makes transporting the generator easier. Because generators can be rather heavy, the heavier types are mounted on wheels.

Is it worthwhile to invest in natural gas generators?

Natural gas generators are more cost-effective, efficient to operate, and environmentally friendly than other fossil-fuel generators. They are, however, less adaptable than other types of generators and may not be the ideal option for all applications.

How much does a Generac whole-house generator set you back?

A whole-house Generac generator can cost anywhere from $12,000 to $15,000 to purchase and install. Although Home Depot and Lowes have financing alternatives for generator installation, interest can increase the total cost.

Is it cheaper to utilize a natural gas generator to power your home?

Calculations can be complicated because electricity prices, as well as the cost of fossil fuels like natural gas, propane, and gas, and diesel, vary by state, and generators provide varied degrees of provisional power, from covering essentials to your complete home’s needs. However, we’ve included some average values based on current projections below to assist you get a better idea of operational costs when calculating fuel prices:

Getting ready for a tailgate party with a gasoline generator? The most cost-effective energy source is not gas-fueled generators. With an average gasoline price of $2.89 per gallon (as of July 2018 estimations) and a typical 5-kilowatt generator used to power solely “survival appliances” consuming roughly 0.75 gallon per hour, running a generator for a day would require about 18 gallons, costing $52/day in fuel.

Portable diesel solutions, based on an average fuel cost of $3.17 per gallon and a 20-kilowatt generator capable of powering major requirements like HVAC, well pumps, and water heaters, consume roughly 1.6 gallons per hour and cost about $122/day in fuel expenditures.

Propane is a cleaner alternative to gas and diesel generators, but it burns more fast. When using 20-pound tanks to fuel your vehicle, it might also be more expensive than gasoline. However, if you have a huge tank on site, the calculations change. A 20-kilowatt portable generator consuming 3.45 gallons per hour would consume 83 gallons in a day, costing almost $200 in fuel. Is there a tank on site? A 22-kilowatt standby generator (which automatically kicks in when electricity goes out, as opposed to a portable unit) can eke out a little more power, burning roughly 3.6 gallons per hour at full load for slightly over $200 per day.

A ‘whole home’ standby generator provides more efficient electricity generation in locations prone to power outages and have access to natural gas. Operational costs will range from $20 to $40 per day, depending on generator size, and will cost around $3.26 per thousand cubic feet.

How Much Does (Equivalent) Grid Power Cost?

Given your monthly power bill, you undoubtedly have a rough notion of how much electricity you use on a daily basis. Though power rates vary by state/region, according to the most recent information on average electricity costs countrywide, the average monthly bill in 2017 was $111.67. When you double it by 30 days per month, you get around $3.72 per day or $0.15 per hour for grid-based power.

What’s Better, Grid or Generator Power?

It doesn’t take a math genius to figure out that grid power is significantly less expensive than running a generator on any fuel type on a daily basis. In general, the simplicity of using grid electricity and reduced expenses make it a more cost-effective option over time. Running a generator is also more environmentally beneficial than using grid power. Despite the higher expense, most people would consider spending a little more to fuel a generator to provide power in the case of an outage to be a worthy investment.

Is a whole-house generator eligible for a tax credit?

Under the Energy Star tax credit guidance, the federal government does not provide tax credits for building a whole-house backup generator. So don’t bother asking why you can’t seem to locate where you may claim your credit. It isn’t there.

Different states and countries, on the other hand, provide tax advantages and rebates for the installation of backup power systems. California, for example, has a commendable Self Generation Incentive Program (SGIP), which provides tax breaks to persons who build certain backup power systems.

Unfortunately, this does not guarantee that you will receive a tax credit for your entire home backup generator. California’s SGIP, for example, only provides refunds for renewable energy sources, which a generator is not. So. It’s a good idea to double-check with your state and municipal governments.

Size of the Generator

Of course, the size of the generator is determined by your daily power usage. The process begins with a visit from the installation team to your home prior to making a purchase. The team will assess the type of system in your home and examine to see if it has a good pump, a good hot water heater, a good number of lights, and home appliances.

If you live in an average-sized house and only need to power one large item at a time, a smaller generator will suffice. Make a list of what appliances, lights, and heating and cooling systems you’ll need if the power goes out. To figure out what size you’ll need during a power outage, add up all the watts.

Fuel Type Of the Generator

You’d like to run your standby generator with natural gas, propane, or another readily available fuel. This gasoline can be stored in large tanks. Portable generators, on the other hand, require diesel or gasoline, and you’ll have to buy a lesser amount of fuel each time you use the generator.

You can use a solar-powered generator if you want a portable solution but don’t want to store liquid fuel. It functions in a unique way, keeping the batteries charged for future usage.

Different generators have different advantages and disadvantages. However, keep in mind that the cost and availability of fuel should be the primary factors in your decision.

Location of the Generator

In general, the position of the generator installation is dictated by the location of the home circuit panel. The circuit panel will be connected to the generator and the transfer switch, which will be located below. Generators are usually placed outside the house, a few feet away from the circuit breaker. You are allowed to relocate the source of fuel a few feet in one direction to make it more convenient.


You can power a few appliances and lights with a battery generator. However, using it in conjunction with a portable generator can allow you to run other small appliances and charge your phones while the portable generator is used to power your HVAC system and other large appliances.


Want to stay up to date on the status of your backup generator while you’re away? Investing in a wireless monitor can be the best choice for you. This will notify you if the generator is running while you are away from home during a power outage.

Smart Load Manager

If your generator isn’t up to the task, consider employing a clever load manager. It will give priority to the regions that are powered by your generator and allow you to switch when necessary.

The Contractor You Choose For the Installation

In addition, the cost of installing a whole-house generator is determined by the contractor you use. Contractors do not all charge the same rate for their services.

Generator Unit Installation Cost

The typical cost of installing a whole-house generator is $5000, but it can go up to $11000 if the installation is complicated. People typically pay between $5000 and $6000.

Whole-House Generator Cost

A whole-house generator costs between $5000 and $60000 to install, including the transfer switch ($1000) and other supplies. Setup, delivery, and connection to the electric panel and fuel supply are all included in this price. The transfer switch is kept inside, while the rest of the work is done outside.

Transfer Switch Installation Cost

The transfer switch is installed indoors and costs between $1800 and $2800. The installation of a transfer switch necessitates the opening of a wall, which may be opened again for future maintenance.


1. What is the best location for a whole-house generator?

Generators must be installed outside and at least 5-6 feet away from flammable objects, doors, vents, and windows, according to standard regulations.

2. How long can a generator operate indefinitely?

Ans. Generators’ continuous runtime varies. Standby generators operate constantly until the power is restored, which could take days or weeks. Portable generators, on the other hand, run till the fuel runs out.

3. How much does a generator cost for a home of 2,000 square feet?

Ans. A whole-house generator for a 2000 sq. ft. house costs on average $6000 to $10000, including labor and installation.

Is it possible to power an entire house with a natural gas generator?

The total wattage equals the size of whole-house natural gas generator required. A 15 to 25% gap between the power required and the generator’s maximum capacity ensures that the generator can power the entire house.

When it comes to natural gas generators, how long do they last?

HONL: A natural gas standby generator has the same life expectancy as a diesel generator. Standby generators have a typical lifespan of 25 to 30 years. Engine life is determined by run hours, maintenance cycles, and installation quality for applications that are not in standby mode. 5.

How long can a natural gas generator run?

A generator’s concept is that it can run eternally as long as it’s fueled. Natural gas and propane are the two most used fuel sources. Diesel and gasoline are also used by some generators.

Natural gas and propane are the preferred fuels because they do not become stale and burn extremely cleanly. This solves the issues that come with gasoline carburetors.

If your generator is hooked up to a natural gas line, you’ll have virtually unlimited fuel from the utility company as long as natural gas is available.

Propane is often kept on your property in big tanks. The size of the tank can range from 250 to 1000 gallons.

The amount of propane you use is determined by demand. However, it’s usually around 1 1/2 gallons every hour, or around 36 gallons of propane per day.

Is a Kohler generator superior to a Generac generator?

While there are exceptions, Kohler generators are generally superior if you require a quiet, long-lasting standby generator near your home. Generac generators perform better in more demanding settings and have a wider range of options, although they are typically louder than Kohler generators.

However, merely stating that one brand is superior to another is not necessarily the most effective method of locating a generator for your residence. We propose that you consider all of the advantages and disadvantages that the manufacturers offer for their generators, as well as your total options.
