How much does it cost to install a standby generator at home?

Installing a home standby generator is a custom project, so final cost is confirmed after an on-site assessment and written quote. Most price variation comes from the generator’s size (how many circuits or whole-home loads you want to cover) and the site work needed. Our electricians install and service whole-house generators across the Salem area, so we’re familiar with local utility and property conditions. In our experience, the transfer switch often sets the tone for panel work, not just the generator itself. Free quotes and financing options are available.

Key factors that drive price:

• Power capacity (kW) and automatic transfer switch type
• Fuel supply needs (natural gas meter/line work or propane setup)
• Electrical panel upgrades or load-management requirements
• Site prep, pad, trenching, distance to utilities, and permitting/inspections

Have a licensed electrician perform a load calculation before you choose a generator size.
