National Baseline & Scope Drivers
Installing a permanently mounted standby generator with an automatic transfer switch for whole-home backup power. National planning range for this job sits between $5,000 and $22,000.
Key Price Drivers for Whole-House Generator Installation
- Generator capacity: A 10 to 14 kW unit covers essentials. A 22 to 24 kW unit runs most of a 2,000 square foot home including HVAC. Each step up in kW adds $1,500 to $3,000 in equipment cost.
- Transfer switch type: A whole-house transfer switch replaces the main panel interface and costs more than a critical-circuits subpanel switch. Generac, Kohler, and Cummins bundle switches with their units; third-party switches vary in compatibility.
- Fuel source and line work: Natural gas units need a plumber to extend the gas line — often $500 to $2,000. Propane requires a tank install or upgrade. Diesel is rare in residential.
- Pad, conduit, and distance from the house: Generators must sit on a level pad, typically 5 feet from windows and doors per code and manufacturer requirements. Long conduit runs from the generator to the transfer switch add labor.
- Permit and utility coordination: Electrical and gas permits are both required. The utility may need to verify gas line capacity before approving a large generator on an existing residential line.
