Propane Generators

When power outages occur, critical systems can quickly be disrupted. A propane generator offers dependable backup energy to keep your home or business running safely and efficiently. Because propane is stored on-site, it remains available to deliver continuous energy during a power failure. 

Propane-powered generators offer reliable performance, long-term fuel stability, and cleaner operation, making them  a trusted solution for uninterrupted energy. 

Whether you’re protecting your household or safeguarding commercial operations, Suburban Propane can help ensure your generator has the fuel it needs when it matters most.

Benefits of Propane Generators

Propane generators offer several advantages that make them ideal for both residential and commercial settings.

Reliable, Immediate Power Supply

The biggest benefit of propane generators is their ability to power your home during an outage. With your fuel supply already on-site, you can avoid issues like closed gas stations, delivery delays, and supply shortages that may occur during severe weather. With fast-start performance capabilities, propane generators keep essential systems operating to help support energy security and peace of mind.

Cost Efficiency

Propane generators are often more cost-effective to operate over time compared to fuel alternatives like gasoline or diesel. Propane burns efficiently and cleanly, reducing maintenance needs and extending the life of your equipment. Fewer deposits and cleaner combustion result in fewer repairs and less downtime.

Long Shelf Life

Propane does not have the same fuel degradation, storage concerns, or spill risks commonly associated with diesel or gasoline, making it a more reliable backup energy source.

Cleaner Emissions Compared to Gasoline and Diesel

Propane is considered a cleaner burning fuel, meaning it produces fewer greenhouse gas emissions compared to gasoline or diesel generators. Cleaner combustion reduces engine wear and helps maintain optimal generator performance over time, making propane a practical option for home backup systems, provided they are properly installed and ventilated. For safe operation, always use propane generators outdoors and follow manufacturer guidelines for proper placement.  

Types of Propane Generators

Standby Generators

Standby propane generators are permanently installed outside your home and are connected directly to your propane supply. These systems automatically detect loss of power f and switch on within seconds.

Because of their seamless power restoration and long-term reliability, standby generators are ideal for:

• Whole-home backup power
• Medical equipment sustainability 
• Commercial facilities requiring continuous operations
• Non-disruption of Data centers and security systems

Portable Generators

Portable generators are small, mobile units used for temporary or supplemental power. They require manual setup and startup but offer more flexibility than standby generators.

Portable propane generators are often used for:

• Temporary commercial and residential job sites
• Small residential power needs
• Outdoor events
• Supplemental emergency backup

Because portable generators run on propane cylinders, they offer a convenient, portable solution for continuous dependable power wherever needed.

Propane Generators Are Used In:

Commercial Capacities

Businesses rely on backup power to protect operations, equipment, and revenue. Power interruptions can lead to costly downtime, and propane generators offer a dependable safeguard. Some of the top industries that use propane generators include:

• Agriculture: Farms and agricultural facilities require reliable backup energy for irrigation, frost protection, crop drying, and heat for buildings or livestock. 
• Builders and Construction: Construction sites frequently operate in areas without reliable grid access, so portable generators can power tools, lighting, offices, and equipment.
• Healthcare and Medical Facilities: Hospitals, clinics, and long-term care facilities depend on continuous power to support critical equipment, climate control systems, and patient monitoring devices. Because they support critical care, generator systems in healthcare settings should be handled by experienced professionals and set up to meet strict safety standards.
• Warehousing and Distribution: Warehouses and logistics facilities rely on electricity for inventory systems, climate-sensitive storage, lighting, and security. 

Residential Capabilities

For homeowners, propane generators deliver energy resilience and peace of mind. During outages, they can power:

• Heating and cooling systems
• Refrigerators and freezers
• Sump pumps
• Medical devices
• Security systems
• Lighting and essential appliances

A standby generator can help keep your home or business safe and operational even when the grid is down.

Propane Generator FAQs

Does propane go bad in a generator tank?

No, propane does not go bad in a generator tank. Propane has an indefinite shelf life and doesn’t degrade over time when stored properly. This makes it ideal for emergency backup systems.

What size propane tank do I need for a standby generator?

The tank size you need for your standby generator depends on the generator’s fuel consumption and how long you want it to operate during an outage. Many whole-home standby generators are paired with 250-gallon or 500-gallon tanks to support extended run times.

Will my generator automatically switch on during an outage?

If you have a standby generator with an automatic transfer switch, then yes, it will automatically switch on during a blackout. Portable generators require manual startup as they cannot detect service interruptions on their own.

How long will a propane generator run during an outage?

Run time for a propane generator depends on your tank size and load demand. A properly-sized tank can support a standby generator for several days or longer, depending on your usage.

Can Suburban Propane install and fuel my generator?

Yes! Suburban Propane can supply and deliver all the propane your generator system needs. Contact your local service center to discuss installation coordination, tank sizing, and ongoing fuel delivery options.
