Why New Jersey Homeowners Need Generators
Protect your family from New Jersey's severe weather threats.
New Jersey is one of the most storm-vulnerable states in the Northeast, with exposure to nor’easters, coastal flooding, and hurricane remnants. Superstorm Sandy in 2012 left over two million New Jersey households without power, some for more than two weeks. The state’s dense population, aging infrastructure, and extensive tree canopy create conditions where even moderate storms can cause widespread outages. Summer heat waves add additional strain to the grid with rolling brownouts. New Jersey homeowners who install standby generators gain critical protection against a state that experiences more frequent and severe weather events than most Northeast states.
