Utility rules and programs for Lafayette
Lafayette Utilities System (LUS), SLEMCO and Entergy Louisiana serve Lafayette County, so which rules apply depends on your address.
| Utility | Type | Generator rules |
|---|---|---|
| City of Lafayette | city-owned | Ask your utility and your parish or city permit office. We found no Louisiana rule specific to generator transfer switches; the 2020 National Electrical Code applies statewide, and SWEPCO’s rider requires a lockable manual disconnect (or a qualifying inverter) so solar cannot feed power onto the lines. |
| Southwest Louisiana E M C | member-owned cooperative | Ask your utility and your parish or city permit office. We found no Louisiana rule specific to generator transfer switches; the 2020 National Electrical Code applies statewide, and SWEPCO’s rider requires a lockable manual disconnect (or a qualifying inverter) so solar cannot feed power onto the lines. |
| Entergy Louisiana LLC | investor-owned | Ask your utility and your parish or city permit office. We found no Louisiana rule specific to generator transfer switches; the 2020 National Electrical Code applies statewide, and SWEPCO’s rider requires a lockable manual disconnect (or a qualifying inverter) so solar cannot feed power onto the lines. |
Program details are from each utility’s own pages (read October 2026). See the Louisiana incentives table for statewide credits and a status for every program.
What to plan for in Lafayette
- Lightning (very high): Lightning causes short outages and damages electronics. Surge protection and a battery that switches over automatically protect the things you care about.
- Hurricanes (very high): Hurricanes can mean a week without power. A standby generator on natural gas or propane, or a battery with solar, beats a stack of gas cans; check flood height before you site equipment.
- Cold waves (relatively high): Cold waves raise demand and can cause both outages and frozen pipes. Keep at least one room warm with a battery-run heater circuit or a generator.
