Quick answer
Generac, by 02 Energy performs electrical panel and service upgrades across New Jersey - moving homes from an undersized 100-amp panel to 200 amps, replacing aging panels, and adding subpanels for extra capacity. Work is done by a licensed NJ electrical contractor (Lic. 34EB00941600), with the permit and utility coordination included and a written quote provided at a free on-site assessment before any work begins.
Why homes outgrow their panel
A 100-amp panel was standard for decades and is still enough for some homes. It stops being enough the moment you add real load - central air, an EV charger, a standby generator, a hot tub - on top of everything already running. When a panel is at its limit, breakers trip under normal use and there is no room left to add anything new without a nuisance trip becoming a daily event.
Options
Three ways we solve capacity problems
Every project varies with panel condition, wiring, and what you are adding - we give you an exact written price at the free assessment.
Service upgrade, 100A to 200A
More capacity for EV chargers, generators, central air, and everything modern homes run at once. Includes utility coordination.
Subpanel
Dedicated capacity for a garage, finished basement, addition, or future circuit without touching your main panel.
Warning Signs
Signs your panel is telling you something
Repeated tripping
A breaker that trips more than occasionally is telling you the circuit, or the panel, is carrying more than it should.
Flickering lights
Lights dimming when the AC or a major appliance kicks on is a common sign the panel or service is undersized.
Aluminum wiring or fuses
Homes built before the mid-1970s sometimes carry aluminum branch wiring or a fuse box, both of which insurers and inspectors flag today.
New major load coming
An EV charger, generator, hot tub, or central air addition is the most common reason a 100-amp panel needs to become 200 amps.

Panel & Service Upgrade FAQs
What are the signs I need an electrical panel upgrade?
Breakers that trip repeatedly, a panel with aluminum wiring or fuses instead of breakers, flickering lights when appliances kick on, or adding an EV charger, a generator, or a hot tub to a 100-amp panel are the usual triggers. Any one of those is worth a free assessment before you add more load to a panel that is already at its limit.
How long does a panel or service upgrade take?
Most residential panel upgrades are completed in a single day. Service upgrades that involve the utility company's equipment can take longer depending on their scheduling, which we coordinate on your behalf.
Will the power go out during the upgrade?
Yes, briefly. A panel or service upgrade requires disconnecting power to swap the equipment safely, so expect a planned outage for part of the work day. We tell you the expected window before we start so you can plan around it.
Do I need a permit, and do you deal with the utility company?
A township electrical permit is required for panel and service upgrades in New Jersey, and a service upgrade also requires coordination with the utility company to disconnect and reconnect service. We handle both - permit, inspection, and utility coordination - as part of the job.
What drives the cost of a panel upgrade?
The main factors are whether it is a straight panel replacement or a full service upgrade (100A to 200A), the condition of your existing wiring and grounding, and any code-required updates the inspector flags along the way. We walk the panel and give you an exact written price at the free assessment - no guessing over the phone.
Can you add a subpanel instead of replacing my whole panel?
Often, yes. A subpanel adds dedicated capacity for a garage, finished basement, addition, or future circuit without touching your main service, and it is usually the faster and lower-cost path if your main panel still has room to support it.
