How Do Whole-House Generators Work?
Sometimes called a fixed standby generator, a whole-house generator is installed permanently outside your home on a concrete pad in your yard. Whenever there is a power outage or equipment failure, the whole-house generator will automatically provide power straight to your home’s electrical panel, even if you’re not home.
An automatic transfer switch disconnects you from your utility as soon as service is interrupted. An internal combustion engine powers the system. The generator can energize your home nonstop for days. When power is restored, the generator returns to standby mode, ready for the next power outage.
Whole-house generators have a seamless integration with your home's existing electrical system, allowing them to kick in automatically without manual intervention. This ensures a smooth transition to backup power, minimizing the disruption to your daily activities. Additionally, modern whole-house generators are designed with noise reduction technology, making them less intrusive in residential environments. These generators are also engineered to handle peak loads, providing consistent power for essential and luxury appliances alike, thus validating their value during extended outages or severe weather conditions.
Whole-House vs. Portable Generators
Whole-house generators offer higher power levels than portable generators and have the added convenience of automatic power. Portable generators are typically used in camping, tailgating, job sites, and other outdoor activity scenarios. These types of generators are mobile and can power individual items, such as appliances and lamps. You can turn them on and off as needed.
Whole-house generators are permanently installed outside and supply power to your entire home. You have nothing to do with turning them on and off – they work automatically, reacting to your home’s need for power.
Unlike portable generators, which run on gasoline or diesel you provide, whole-house generators are fueled by your home’s existing fuel supply, such as natural gas, liquid propane (LP), or diesel. And because they are permanent appliances, they have the added benefit of adding value to your home.
The permanence of whole-house generators means they require little intervention once installed. They connect to substantial fuel sources, such as natural gas lines, which provide an uninterrupted fuel supply, thereby eliminating the need for frequent refilling required by portable versions. Their automatic operation not only ensures immediate power restoration but also enhances safety by eliminating the handling of flammable fuels under potentially hazardous conditions. Therefore, they represent a long-term investment in home resilience and efficiency that pays off during extended power outages by preserving food in refrigerators, maintaining climate comfort, and even protecting home-based business operations.

The Average Cost of Whole-House Generators
Whole-house generators can cost anywhere from $3,000 to $20,000, depending on the size needed. To determine your home’s ideal generator size, you need to assess your needs during a temporary emergency. Don’t include powering all of the appliances in your home in your assessment.
- Installation Costs: Includes professional installation and any site prep required.
- Maintenance & Fuel: Consider regular maintenance and fuel usage for cost-effectiveness.
- Longevity: With proper maintenance, your generator can provide reliable service for many years, saving you money over time.
The investment in a whole-house generator also includes the peace of mind that comes with not having to worry about unexpected power outages. Properly installed and maintained systems can significantly increase property value, especially in regions prone to weather extremes. It's crucial to consider long-term savings from avoiding potential damages due to power loss, such as repairs needed for spoilage in refrigerators, pipe damage from lack of heating in winter, or the inability to operate critical home systems. Financing options are often available, making it easier to manage the initial investment and start benefiting from an uninterrupted power supply right away.
