Local Long Island Expertise

Standby Generators for Long Island Homes

No region values backup power like Long Island. Hurricanes and nor'easters routinely knock out PSEG power for days; homes on well water lose their water; South Shore basements flood when the sump quits. A standby generator is less a luxury than a plan.

We install whole-home generators with an automatic transfer switch that takes over in seconds — on natural gas where available, propane where it isn't (common across Suffolk). We size the unit to keep the well, sump, heat and the whole house running through a multi-day outage.

Your utility is PSEG Long Island and your permit comes from the local town building department — we coordinate PSEG, file the town permit, arrange the fuel hookup and handle the inspection.

Long Island Generator Questions

Generator Installation on Long Island — FAQs

Why are generators so popular on Long Island?
Hurricanes and nor'easters cause long PSEG outages; many homes are on well water (no power, no water); and coastal areas flood. A whole-home standby generator keeps everything running automatically.
Who handles the utility and permit?
On Long Island the utility is PSEG Long Island, not Con Edison, and permits come from your local town building department. We coordinate PSEG, file the town permit and manage the inspection.
Gas or propane?
Natural gas where it's available; propane is common across Suffolk where there's no gas line. Either way, we arrange the fuel hookup.
Will it run my whole house?
We size the generator and transfer switch to carry the well, sump, heat, AC and the rest — for as long as the outage lasts.
