Why New Jersey Needs Backup Power
New Jersey was ground zero for Superstorm Sandy, which reshaped how the state thinks about power resilience. Generator installations surged after Sandy and again after Ida's flooding in 2021. High labor costs and complex permitting make NJ one of the more expensive states for installation.
Superstorm Sandy (2012) left 2.7 million NJ customers without power, some for over two weeks. Remnants of Ida (2021) caused catastrophic flooding across central NJ. Power in New Jersey is served by PSE&G, JCP&L (FirstEnergy), Atlantic City Electric. According to the New Jersey State Electricity Profile, the state averages 2.5 outages per year with a mean duration of 7 hours per event.
