Thinking about a standby generator after the last outage? Here's what New Jersey homeowners typically pay to have one installed, what drives the price, and how to tell an honest quote from a padded one.

The installed number is the one that matters: the generator itself is often only about half the story, with the transfer switch, electrical work, fuel line, pad, permits, and labor making up the rest.
Ranges reflect typical New Jersey pricing as reported by local installers as of 2026. Your home's price depends on size, layout, and fuel — the free quotes through this site are based on your actual property, not averages.
Natural gas is the most common choice where a gas line already serves the home: the fuel supply is effectively unlimited, there's no tank to refill, and the generator can run for days through a long outage. Two things to check: your meter and line must be sized to feed the generator alongside your furnace and other gas appliances (a meter upgrade is sometimes needed), and the system depends on gas service staying up — which it historically does through most storms, since it's delivered underground.
Propane is the answer for homes without natural gas service. The fuel is stored in a tank on your property, so you're independent of any utility line — but run time is finite and depends on tank size, and you'll need deliveries to top it off after long runs. Propane units also sip fuel at partial load, so real-world consumption during a typical outage is usually lower than worst-case math suggests.
Either way, a standby generator also needs periodic oil changes during extended continuous operation — manufacturers specify the interval — which is one reason installers push maintenance plans for after the sale.
Ask around any South Jersey neighborhood and you'll hear the same reference point: Sandy. Days without power rewired how this state thinks about backup power, and every nor'easter since has reinforced it. The use cases that actually drive purchases:
It depends on what you want running. Essentials-only setups can work with smaller units; true whole-home coverage — central air included — typically lands in the 14–24kW range for most homes. Square footage alone doesn't decide it; a load calculation does, which is why real quotes start with your panel and your appliance list.
As long as it has fuel and oil. On natural gas, run time is effectively continuous. On propane, it depends on tank size and load. During very long runs, the engine will need an oil change at the manufacturer-specified interval — one of the practical details a good installer walks you through at startup.
Real estate agents in outage-prone areas list standby generators as a genuine selling point, and buyers who lived through Sandy-era outages understand the appeal immediately. Treat any specific resale figure with skepticism — but as a quality-of-life and risk-reduction purchase that also shows up in listings, it's one of the more defensible big-ticket home upgrades.
Partly. Many homeowners start with a transfer switch hookup for a portable generator (high hundreds to ~$1,500) and move to a full standby system later. What you can't easily do is undersize a standby unit now and stretch it later — sizing right the first time is the cheaper path.
