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

The cost to install a home standby generator varies by home and is confirmed only after an on‑site assessment and written estimate. The biggest driver is generator capacity (how many circuits or whole‑home coverage you want), followed by installation complexity and how the system ties into your main electrical panel. We install and maintain integrated generator systems in the Denver metro, including Commerce City, with licensed in‑house electricians and transparent, no‑surprise pricing.

If you’re comparing options, here are common cost factors:

• Generator kW size and desired load coverage
• Automatic transfer switch type and panel integration
• Distance from generator to panel and required wiring/conduit
• Fuel supply work (gas line routing and meter capacity) and placement pad
• Add‑ons like surge protection or panel upgrades if needed

For many homes, a right‑sized unit with an automatic transfer switch offers the best reliability; a site visit defines whether repair of existing equipment, a smaller circuit‑select setup, or full replacement is the smart move. Schedule an on‑site evaluation to lock in the correct size and exact installation scope.
