"Just an outstanding experience end-to-end with Matt. He responded to the outreach within minutes and was able to give me a quote a few hours later that was very fair. We installed an induction stovetop and needed a new 50amp circuit and line run in our old house, crawl space and all. He showed up right on time, and made quick work of it. Very professional and friendly. He even stayed a little longer after the job was complete to help me diagnose another problem. Couldn't recommend him more highly. Would hire him again in a minute."

"Jose was great to work with. He was quick to respond, came by on short notice to have a look and provide a quote for the work (Installation of one new smart thermostat and replace one old thermostat with new thermostat; requiring separation of baseboards due to wattage). Very competitive pricing, showed up on time at each appointment and got the work done quickly. He left the place cleaner than before, and walked me through everything after the installation. Can highly recommend Jose for any electrical work!"

"Empower Electric did a great job. I had them rewire my Multi Family home in Everett. I also had them rewire my second floor of my home in Wilmington. They also did some outside lights for me as well. Jimmy was very professional and gave me a great price."

"I had both electricians and plumbers who performed the work of the generator installation, transfer install as well as the plumbing to the propane tank-generator. Considering the time of year with hurricanes and inclement weather, the generators and transfer switches were backordered however, my job was completed within a 2 month period from the initial quote to finish- considering all of the obstacles that we faced, they did a fantastic job."

Generator Install questions, answered by experts

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.

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.

Yes, in some locations, it is required by the National Electric Code (NEC) to have a transfer switch installed for electrical emergencies. In addition to following electrical code, generator transfer switches ensure your home is fully protected during a power outage. By switching the power from the main breaker to the generator breaker, you can seamlessly operate your HVAC, lights, appliances, devices, and more during an emergency. 

A portable generator can supply power to selected appliances and circuits in a home, but it's generally not designed to handle the entire household's electrical needs simultaneously. Portable generators have limited wattage capacity, so they are only designed to power essential devices and electronics temporarily until local power is restored. If your power needs outweigh the capabilities of a portable generator, consider installing a whole-home generator instead.

The average cost to install a home generator is $5,200, but total costs can range from $500 to $18,000 or more. The final price depends on several factors, including the generator's size, type, brand, fuel source, and the cost of labor and assembly. The generator's size is the most significant cost factor, as units that can power larger homes with higher energy demands cost more.

Cost breakdowns by generator type are typically as follows:

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

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

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

To ensure you get the right size unit for your needs without overpaying, consider hiring an electrician to calculate the electrical load of your essential appliances. It is also recommended to get at least three quotes from qualified installers to find the best fit for your budget.
