Utility rules and programs for Sulphur
Entergy Louisiana, Cleco, Beauregard Electric Coop, and Jefferson Davis Elec Coop, serve Calcasieu County, so which rules apply depends on your address.
| Utility | Type | Generator rules |
|---|---|---|
| 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. |
| Cleco Power 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. |

What to plan for in Sulphur
- 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.
- Tornadoes (relatively high): Tornado-season storms cut power quickly. A battery that switches on by itself, or a portable generator ready to go, covers the first night; sirens and weather radios need power too.
