Power outages in Elizabeth and Union County are not rare events. Nor'easters, summer thunderstorms, aging infrastructure, and the occasional major storm event can leave homes without electricity for hours or days. A whole-home standby generator eliminates the disruption, keeping your lights on, refrigerator running, sump pump active, and medical equipment operational when the grid goes down. MainStreet Service Pros connects Elizabeth, NJ homeowners with licensed electricians who install standby generators from the industry's top manufacturers.
How Standby Generators Work
A standby generator sits outside your home on a concrete pad, connected to your natural gas or propane supply and your electrical panel through an automatic transfer switch. When the generator detects a power outage -- which takes about 10-30 seconds -- it starts automatically and powers your home without any action from you. When utility power is restored, the generator transfers the load back and shuts down. No extension cords, no manual switching, no trips to the basement in the dark.
Generator Sizing for Elizabeth Homes
Proper sizing is critical. An undersized generator cannot power everything you need, while an oversized one wastes money. Most Elizabeth homes need a 16-24 kW generator for whole-home backup. A 16 kW unit handles essential circuits -- lights, refrigerator, sump pump, a few outlets, and one HVAC zone. A 22-24 kW unit powers the entire home including central air conditioning.
Our electricians calculate your specific power requirements by analyzing your electrical panel, identifying essential circuits, and accounting for starting surge loads from motors (HVAC compressors, sump pumps, and well pumps draw significantly more power when starting than when running).
Generator Installation Costs
A whole-home standby generator installed in Elizabeth, NJ typically costs $5,000-$15,000 depending on the size and brand. A 16 kW Generac or Kohler unit with automatic transfer switch, concrete pad, gas line connection, and electrical hookup typically runs $6,000-$9,000 installed. A 22-24 kW unit for whole-home coverage costs $9,000-$14,000 installed. Commercial generators for businesses range from $10,000-$50,000+ depending on power requirements.
The installation requires both an electrical permit and a gas permit in Elizabeth. Our electricians coordinate both permits, schedule required inspections, and handle the gas line connection (or coordinate with a licensed plumber for the gas work).
