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

Standby generator installation cost is confirmed after an on-site assessment, because price depends on the system size, fuel source, and electrical scope needed for your home. Most of the budget typically goes to the generator itself and the transfer switch that makes the changeover safe. Our process includes a load calculation, guidance on manual vs automatic transfer switches, permitting support, and full commissioning with outage simulation and Mobile Link setup when applicable. We handle these installations for homeowners near French Settlement as part of our regular service area. A right-sized unit that can start reliably on your available gas pressure often saves more over time than an oversized set. If you only need a few circuits, a portable setup with a manual switch can lower the upfront cost.

Cost drivers we confirm during the walkthrough:

• Generator size in kW based on load calculation
• Fuel source: natural gas or propane and connection needs
• Transfer switch type: manual or automatic, plus any prioritized-load modules
• Electrical scope: feeder runs, selected-circuit wiring, surge protection, and permitting

Schedule a site visit so we can size the system, verify fuel availability, and provide a written, code-compliant estimate. <br/> Updated: 2026-03-13 <br/> Need help in French Settlement, LA? Call (225) 314 8961 or book online.
