Bergen County Whole Home Generator Installation Guide
Whole-House Generator Installation in Bergen County, NJ
Costs, Process, Permits, and FAQs from a Local Electrical Contractor
Power outages in Bergen County and Northern New Jersey have become more frequent and more disruptive in recent years. Between seasonal storms, aging infrastructure, and increased electrical demand, many homeowners are choosing to install natural gas standby generators to protect their homes, families, and daily routines.
This guide explains how whole-house generator installations actually work in New Jersey, what affects pricing, and answers the most common questions we hear from homeowners considering a standby generator system.
What Is a Whole-House Standby Generator?
A whole-house standby generator is a permanently installed backup power system that:
Runs on natural gas (or propane where applicable)
Automatically starts when utility power is lost
Supplies power through an automatic transfer switch (ATS)
Can power either the entire home or selected critical loads
Shuts down automatically when utility power is restored
Unlike portable generators, standby generators are fully automatic, code-compliant, and designed to run safely for extended outages without homeowner intervention.
How Much Does a Generator Installation Cost in Bergen County, NJ?
For most homes in Bergen County, a professionally installed 18–24kW natural gas generator system typically falls within the following range:
Typical Installed Budget
