Utility rules and programs for Trenton
Public Service Elec & Gas serves homes in Trenton.
| Utility | Type | Generator rules |
|---|---|---|
| Public Service Elec & Gas Co | investor-owned | A generator transfer switch is electrical work: use a licensed New Jersey electrician and ask your town’s construction office about the electrical permit (we did not confirm a rule written specifically for generators). |
Program details are from each utility’s own pages (read October 2026). See the New Jersey incentives table for statewide credits and a status for every program.
What to plan for in Trenton
- Strong winds (very high): High winds knock out lines on ordinary days. A battery or portable power station handles the common short outages; add a generator for multi-day repairs.
- Winter weather (very high): Winter storms and cold snaps combine outages with heating demand. Plan for the furnace blower or heat pump, not just lights, and keep a fuel supply you can reach in snow.
- Ice storms (very high): Ice storms bring down lines for days. A standby generator with a transfer switch, or a battery sized for the fridge, furnace blower and well pump, matters more than a small power station.
