Propane Standby Generators
Propane standby generators provide automatic, on-site backup power that keeps critical systems operating under grid disruptions and strengthens energy resilience for homes and commercial facilities.
When Reliability Is Non-Negotiable
Propane standby generators are a reliable option for homes, businesses, and facilities where power is essential, including locations that cannot afford downtime, face frequent outages, rely on mission-critical systems, or require low-emission, low-noise operation.
Automatic Power Restoration
Automatically restores power within seconds of an outage, keeping critical systems running without interruption.
On-Site Energy Security
On-site power storage supports continuous operation during outages, reducing reliance on real-time fueling or grid-dependent refueling systems.
Always Ready Energy
Stable, available energy that does not degrade over time, reducing maintenance concerns common with diesel generators.
Cleaner Operation
Fewer harmful emissions than diesel, supporting cleaner air in homes, workplaces, and communities.
Quieter Performance
Quieter operation than diesel generators makes propane well suited for homes, businesses, and noise-sensitive locations.

Use the Generator Sizing Tool
Use this interactive tool to see how switching from electric to propane appliances reduces demand on a home’s backup power system, allowing you to specify a smaller, more cost-effective standby generator.
When more key systems run on propane, the standby generator supports less electrical demand, making it possible to specify a smaller unit that can save thousands in upfront costs while maintaining reliable whole-home backup power.
