"Highly recommend contacting them for electrical work! Responded quickly to come and give a quote for a generator hook up. Explained everything thoroughly and gave helpful suggestions as this was my first experience getting a generator to power the house. Very reasonable pricing. From first contact to getting it installed in under 2 weeks. Very happy!!"

"If I could give Jeremy and his team 10 stars I would, they are simply that good! He has installed recess lighting in both of the houses we have owned. Both houses we have owned have a light switch connected to an outlet. He installed new lighting and made sure that the wiring to the outlet works without a switch. He did this for both our living room and upstairs master bedroom. We also asked him if he would install a generator plug outside as well. He installed it and made sure we knew A.) how to run the generator. B.) How to turn the panel off and switch the main breaker on for the generator and C.) Made sure he labeled all breaker switches we were able to use while using the generator to power the house. I will never use anyone but Jeremy and JMP Electric moving forward on any electrical for my house. I would highly recommend him and his company. He is just simply amazing. Look no further when looking to have someone do your electrical. You really won't find anyone better."

"I hired Elevate Electric to install multiple electrical outlets in my basement after a waterproofing project. Kyle installed electrical outlets, ran a new circuit, and upgraded a breaker. The result looks outstanding! The new circuit wire is routed cleanly and he even dressed up some previous wiring too. Kyle shaped conduit around existing items along the basement wall making the whole utility room look good. This is probably the 4th time I have hired Kyle for electrical work. He consistently does great work. The quality is top notch and his pricing is extremely fair. You cannot go wrong with Elevate."

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

You can determine what size generator you need for a transfer switch by matching the switch to the largest outlet on your generator. Larger generators can power up to 10 circuits, while most 5,000-watt generators can provide power to six circuits. So, if your generator’s largest outlet is 30 amps, you’ll need a 30-amp transfer switch.

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 most municipalities, you will need a permit to install a permanent home generator, including emergency backup, partial-home, and whole-home generators. A permit for a generator usually costs between $50 and $250, depending on where you live. Your electrician or certified generator installer will usually pull the permit for you—and might be required to do so by your building department—but you’ll be on the hook for the cost of the permit. You should ask your installer before agreeing to any work if they will pull the necessary permits for your project.

Whole-house generators need to be installed on level ground several feet away from walls and other objects. Because they tap into the electrical system directly, they usually need to be close to your home electrical panel for a transfer switch installation. It also helps with installation if they are near to a gas line or propane tank installation.
