There seems to be an unending list of decisions to make when it comes to generator installation. One of those options is which fuel source works best for whole-house generators. Two of the most popular fuel choices are natural gas and liquid propane. So how do you know which is the best choice? It all depends on local utility access and storage needs. In this guide by Mr. Electric, our electricians will compare natural gas vs. liquid propane so you can make the right decision for your needs.

Natural Gas: Convenient and Continuous

Natural gas is the preferred fuel source for many homeowners who have access to a municipal gas line. Because it is delivered through underground utility lines, you don't have to worry about refilling or storing fuel.

One of the advantages of natural gas is its virtually unlimited supply. As long as the gas utility remains operational during a power outage, your generator can continue running without interruption. This makes natural gas especially appealing in areas that experience extended outages.

Natural gas also burns relatively cleanly, producing fewer emissions than many other fossil fuels. In addition, homeowners don't have to monitor fuel levels or schedule deliveries.

However, natural gas isn't available everywhere. Rural properties and homes outside municipal service areas often don't have access to a gas distribution system.

Liquid Propane: Flexible and Reliable

Liquid propane is stored in an on-site tank located above or below ground. This makes it an excellent option for homes that aren't connected to a natural gas utility.

One of propane's biggest strengths is its availability. Nearly any property can use propane as long as there's enough space for a storage tank. Propane also has a long shelf life and doesn't degrade over time, making it well suited for emergency backup power.

Propane burns cleanly and can provide excellent generator performance. Because the fuel is stored on your property, you're not dependent on utility infrastructure during an outage.

The main drawback is that your generator can only operate as long as fuel remains in the tank. If an extended outage empties the supply, you'll need a propane delivery before the generator can continue running.

Comparing Fuel Costs

Fuel prices vary by region and fluctuate over time. Natural gas is often less expensive per unit of energy than propane, making it the more economical option for homeowners who use their generators frequently.

Propane typically costs more per gallon, but many homeowners consider the higher operating cost worthwhile because of its availability and independence from utility lines.

When comparing long-term costs, it's important to consider both fuel prices and expected generator usage. This is why it’s a good idea to consult with a nearby electrician when it’s time to install a whole-house generator in your home.

Which Fuel Is Right for Your Home?

The best fuel source depends on your property's location and your priorities. Natural gas is the ideal choice for homes connected to a reliable gas utility because it offers continuous fuel without the need for on-site storage. Propane is an excellent solution for rural homes or properties without natural gas service, providing dependable backup power almost anywhere. A professional electrical service can evaluate your needs and help you make the right choice for your needs.
