Generator Installation · Louisiana
A generator must connect through a transfer switch or an approved interlock so it can never feed power back into utility lines. Electricians install standby generators, portable generator inlets with interlocks, and the transfer equipment for both.
Hurricanes, flooding and heat make generator installation and post-flood electrical inspections common.
Across the South Central, homes deal with long, hot summers, severe storms and occasional hard freezes. Permit offices, utilities and housing stock differ by city, which affects how generator installation is planned and scheduled. These local guides cover the Louisiana cities where we have written specific notes.
After Hurricane Ida left the entire city without power in 2021, standby generators became one of the most requested electrical projects in New Orleans. A standby unit with an automatic transfer switch is often installed on a raised platform to stay above flood levels, and it needs a gas supply sized for the generator and clearances from windows and doors.
Utility: Entergy New Orleans
Hurricanes Gustav in 2008 and Ida in 2021 caused long outages across Baton Rouge, and standby generators are now a common project. A standby unit with an automatic transfer switch needs a natural-gas or propane supply sized for the generator, a pad, clearances from windows and doors, and in flood-prone areas, a mounting height above expected water levels.
Utility: Entergy Louisiana (some outlying areas: DEMCO)
1. Size the load
Circuits that must stay powered are listed and the generator sized.
2. Choose the connection

Electricians set their own prices; local permit fees and utility requirements add to these factors.
Permits come from the city or county where the home is. For example: New Orleans: Electrical permits in New Orleans are issued by the city's Department of Safety and Permits, and historic districts may need separate review for exterior changes. Baton Rouge: Baton Rouge and East Baton Rouge Parish share a consolidated city-parish government, and electrical permits come from its Department of Development; Baker, Central and Zachary issue their own.
New Orleans: Entergy New Orleans. Baton Rouge: Entergy Louisiana (some outlying areas: DEMCO).
Listed interlock kits are accepted in many jurisdictions when installed with a permit. Your electrician will know the local rule.
