Utility rules and programs for Greenville
Entergy Mississippi and Delta Electric serve Washington County, so which rules apply depends on your address.
| Utility | Type | Battery and related programs |
|---|---|---|
| Entergy Mississippi LLC | investor-owned | Its tariff lists a $3,000 low-to-moderate income solar incentive and a $2,000 battery incentive through 2027 (status not confirmed; third parties report them suspended), plus home efficiency programs. We could not confirm a home EV charger rebate. |
| Delta Electric Power Assn | member-owned cooperative | Ask for rebates and rate plans; we have not verified any. |
Program details are from each utility’s own pages (read October 2026). See the Mississippi incentives table for statewide credits and a status for every program.
What to plan for in Greenville
- 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.
- Drought (relatively high): Drought raises fire and heat risk and strains wells. If you rely on a well pump, include it in your backup plan.
- Earthquakes (relatively moderate): Earthquake risk is mainly about secure mounting and gas shut-off for generators; ask the installer to follow local seismic requirements.
