How Much Does Generator Installation Cost in Westchester, NY?
A 22 kW whole-house generator costs $12,000 – $19,000 installed in Westchester (above the NY state average but below NYC — Westchester labor rates are high (NYC-adjacent) but permitting is simpler than DOB).

Westchester County is a high-income suburban market with strong generator demand. Con Edison serves the southern half, and outages from nor'easters and hurricanes are frequent. Hurricane Ida's flooding in 2021 was a turning point — Westchester homeowners saw their neighbors' flooded basements and decided backup power (including sump pumps) was non-negotiable.

FAQ — Generator Installation in Westchester
How much does a 22 kW generator cost in Westchester?
A 22 kW generator costs $12,000-$19,000 installed in Westchester. Above the NY state average due to NYC-adjacent labor rates, but simpler permitting than the five boroughs.
Do I need flood-rated mounting in Westchester?
If your property is in a FEMA flood zone along the Bronx River, Byram River, or Long Island Sound coastline, yes. Post-Ida flood maps may have changed your zone. Check your FEMA designation.
Con Edison or NYSEG — does it matter?
Not for the generator itself. Both utilities require standard transfer switch interconnection. Con Edison serves southern Westchester (White Plains, Yonkers, New Rochelle); NYSEG serves northern Westchester (Bedford, Katonah, Somers).
