  • Prevent basement flooding. Your sump pump is only as reliable as your power. In our area, the worst storms and the worst outages arrive together — a generator keeps the pump running exactly when you need it most.
  • Protect food and comfort. No more throwing out a refrigerator full of groceries or sweating through a summer outage without AC.
  • Support medical equipment. For households that depend on CPAP machines, oxygen concentrators, or home medical equipment, backup power isn’t a luxury. Stay online for work. If you work from home, an outage is lost income. Standby power keeps your internet, computers, and home office running.
  • Stay online for work. If you work from home, an outage is lost income. Standby power keeps your internet, computers, and home office running.
  • Whole-home coverage, automatic transfer. Unlike portable generators, a standby unit is permanently installed, runs on your natural gas line, and switches over automatically — even when you’re not home.

Easy. Fast. Reliable.

Most whole-house standby generator installations in the Chicago area range from roughly $10,000 to $20,000+ installed, depending on generator size, gas line requirements, and electrical work needed. Origins Electric provides a free on-site estimate with exact, upfront pricing for your home.
It depends on whether you want to back up your whole home or just essential circuits like the sump pump, refrigerator, furnace, and select outlets. We perform a custom electrical load calculation to size your generator correctly — most homes fall in the 18kW–26kW range for whole-house coverage.
Most residential standby generator installations take one to three days on site once permits are approved and the unit is in hand. The full process — estimate, permitting, installation, and inspection — typically spans a few weeks depending on your municipality and equipment availability.
Yes. Most whole-house standby generators in our area connect to your home's existing natural gas line, so there's no refueling. When utility power fails, the generator starts automatically and the transfer switch moves your home to backup power in seconds.
Standby generators should be professionally serviced at least once a year — including oil and filter changes, battery testing, and a full operational check. Regular maintenance is the single biggest factor in whether your generator starts when you actually need it.
