Backup power in Rochester

Electricians for generators and transfer switches.

17 pros in Rochester

Rochester's winters shape how people think about backup power. The National Weather Service Buffalo office puts total season snowfall at about 90 inches in the city, near 70 inches to the south and over 120 inches along the lake shore east of town. Ice is the other risk: on the night of March 3, 1991, freezing rain fell for 17 hours, and some homes and businesses were without power for almost two weeks. A standby generator in this area may need to run for days, not hours, so ask any installer how the unit is sized for your whole house or for chosen circuits. Ask who handles the transfer switch, which keeps generator power from feeding back onto the utility line, and who pulls any permit required for the work. Ask for a written quote that names the fuel supply, the placement of the unit and the service plan. Snow can bury a unit, so ask about clearance too.

Before you hire

  1. 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.

  2. Get written quotes from at least three contractors for the same work, and check references from recent clients.

  3. 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 Rochester

How long can an outage last in the Rochester area?

After the freezing rain of March 3, 1991, some homes and businesses were without power for almost two weeks. That is an extreme case, but it shows why fuel supply and running time matter when you compare standby generator quotes. Ask each installer how long the unit can run on your fuel.

Why does snow matter when placing a generator?

Season snowfall is about 90 inches in Rochester and over 120 inches along the lake shore east of the city. Ask installers how they will place the unit so snow does not block its airflow or exhaust, and how you will reach it in winter. National Weather Service Buffalo (source, opens in a new tab)

What should a generator quote include?

A written quote should name the generator model and size, the transfer switch, the fuel connection, the placement, who pulls permits, the work schedule, the warranty and any service plan. Get the same details from each installer so you can compare quotes line by line.

Do I need a transfer switch with a standby generator?

A transfer switch is a standard part of a standby installation. It isolates your home from the utility line while the generator runs, so power does not flow back to the grid and endanger line crews. Ask who installs it, whether a permit and inspection apply, and that it is on the quote.
