Whole House Generator Installation Cost
Reviewed by WattCostLab Editorial Team
Standby generator cost depends on required power, transfer equipment, fuel infrastructure, site preparation, electrical work and permitting.
Size for the loads you actually need
Backing up every household load can require a larger generator than backing up essential circuits. Load prioritization can reduce equipment size and fuel use.
Installation infrastructure matters
Transfer switches, concrete pads, gas-line work, trenching, clearances and electrical modifications can materially affect installed cost.
Compare generators with batteries by use case
Battery storage and generators provide different outage duration, power, maintenance and fuel characteristics. The right choice depends on the loads and outage profile.
