Backup power in Rockford
Electricians for generators and transfer switches.
11 pros in Rockford
Rockford has seen how fast the grid can fail. A derecho on August 10, 2020 brought 70 mph winds and left thousands without power in under two hours, and a freezing rainstorm in February 2023 still had 2,683 Winnebago County residents in the dark two days later. If you are weighing a standby generator, that history is the reason to plan before the next outage. The city requires an electrical permit to install, alter or replace electrical equipment, so ask any installer whether the permit is included in the job and who pulls it. Electrical contractors here need not be licensed, but they must register with the city each calendar year, so ask to see current registration or a licence from another Illinois municipality. Also ask how the transfer switch will keep power from backfeeding into utility lines, and whether your utility has been told about the installation. Get the scope, equipment and permit steps written into the quote before you agree to anything.

Before you hire
A generator wired into your home needs an approved transfer switch, fitted under a permit, so it can’t feed power back into the lines. Plan it before you buy.
Get written quotes from at least three contractors for the same work, and check references from recent clients.
Put it in a written contract: the work, price, deposit, start and finish dates, warranty, permits and clean-up. Paying cash to skip it leaves you no recourse.
Questions about hiring in Rockford
Do I need a permit to install a standby generator in Rockford?
Yes, in most cases. Rockford requires electrical permits to erect, install, enlarge, alter, repair, remove, convert or replace electrical systems or equipment. A generator and transfer switch connect to your home wiring, so ask the installer who applies for the permit and have that written into your quote. City of Rockford (source, opens in a new tab)
Does an electrical contractor in Rockford have to be licensed?
Not under the city rule, but contractors must register with the city each calendar year. They can instead show current registration or a licence from another Illinois municipality. Ask to see the proof before you sign, and keep a copy with your contract and permit paperwork. City of Rockford (source, opens in a new tab)
What should a generator quote include?
A good quote lists the generator size and model, the transfer switch, fuel connection, wiring, permit handling, and who does each task. It should also state the start date, payment schedule and warranty terms. Ask for the same details from each installer so you can compare quotes fairly.
Do I need to tell my utility about a backup generator?
Ameren Illinois asks customers to call it if they plan to install back-up generation. It also says the law requires that no electricity from a standby generator backfeeds into its power lines during an outage. Ask your installer how the transfer switch prevents this, and check what your own utility requires. Ameren Illinois (source, opens in a new tab)
