A home standby generator typically costs between $5,000 and $25,000 to install, with the average price falling around $17,000 for a whole-house generator, depending on the generator's size, brand, fuel type, and the complexity of the installation process required for your home; factors like necessary electrical upgrades and site accessibility can significantly impact the cost.

Key points about home standby generator costs:

  • Power capacity matters: Larger generators with higher kilowatt (kW) ratings, capable of powering more appliances in a home, will be more expensive. 

  • Fuel source impact: Generators powered by natural gas may have lower installation costs compared to propane, depending on existing infrastructure. 

  • Installation complexity: Difficult site conditions, extensive trenching, or the need for electrical upgrades can significantly increase the installation cost. 

  • Professional installation needed: Standby generators require professional installation to connect to your home's electrical system and ensure proper functioning. 

Factors influencing the cost:

  • Generator size (kW): The primary factor determining price, with larger generators costing more. 

  • Brand: Different brands may have varying price points. 

  • Fuel type: Natural gas is often considered more cost-effective than propane for installation. 

  • Local regulations: Permits and compliance requirements can add to the cost.
