Entergy Mississippi LLC rate plans
2 residential plans are currently open to new customers. None of them price by hour, so shifting when you use power won’t change your bill here.
What does Entergy Mississippi cost at a normal month’s usage?
A household using 1,000 kWh a month pays about $1,529 a year on the cheapest of the 2 plans we can price here — Residential Service Single Phase (RS-40C) — and $1,729 on the priciest. Same house, same wires.
| A month of | Cheapest, a year | On which plan | Priciest |
|---|---|---|---|
| 500 kWh | $976 | Residential Service Single Phase (RS-40C) | $1,176 |
| 1,000 kWh | $1,529 | Residential Service Single Phase (RS-40C) | $1,729 |
| 2,000 kWh | $2,625 | Residential Service Single Phase (RS-40C) | $2,826 |
The same plan is cheapest at every level of use here, so the answer does not turn on how much you use. Estimates from the filed tariff, priced hour by hour on a household with central air — not a quote.
How much does the plan you pick actually matter here?
Run the same three-bedroom house with central air through every plan Entergy Mississippi LLC files, and the bill lands anywhere between $1,296 and $1,496 a year. That $200 spread is not a difference in electricity — it is the same kilowatt-hours, from the same wires, priced under different rules. Nobody sends you a letter when you are on the wrong side of it.
The plan most households land on by default, Residential Service Three Phase (RS-40C), comes to about $1,496. The cheapest option here, Residential Service Single Phase (RS-40C), comes to $1,296 — a gap of about $200 a year for a household that never changed a single habit. Whether you can actually capture that depends on when you use power, which is what the calculator below is for.
None of these 2 plans price by the hour, so when you use electricity here makes no difference to what you pay — only how much. That narrows your options to two levers: use less, or pick the plan whose fixed charge and tier structure suit your size of household.
Watch the fixed charges too. Across these plans they run from $382 to $582 a year before a single kilowatt-hour is counted. For a small household that difference alone can outweigh the per-kWh price, which is why comparing cents per kilowatt-hour on its own quietly misleads.
How Entergy Mississippi compares with the rest of the country
Entergy Mississippi is the only Mississippi utility we can price, so there is no in-state comparison to make. Against the whole country there is: run the same three-bedroom house with central air through its default plan at each of the 127 utilities we cover, and Entergy Mississippi lands 57th cheapest — in the cheaper half — at about $1,496 a year against a national median of $1,566. The range runs from $905 at Entergy Louisiana (Louisiana) to $4,726 at San Diego Gas & Electric (California).
The other two households sit in the same place: a small apartment pays about $1,068 here against a national median of $901, and the same house with an electric car charging overnight about $1,830 against $2,067. Effective rate, fixed charge included, is 15.8¢ per kilowatt-hour for the family home.
Inside Entergy Mississippi itself, the gap between its cheapest and dearest plan for that house is $200 a year. That is the part of the bill a customer here can act on; the rest is set by which utility the address falls under.
Which plan would cost you least?
No bill upload, no sign-up. Tell us roughly what a month costs you and what runs on electricity — we price every plan against the same household and show you the gap.
That adds up to 11,445 kWh a year. Compare it to the total on your bill and adjust until it’s close.
Same usage, different plan
$200a year
That is the gap between the cheapest plan you could be on — Residential Service Single Phase (RS-40C) — and the priciest. Not by using less power. By being billed differently for the same power.
| Plan | Per year | Vs best |
|---|---|---|
| Residential Service Single Phase (RS-40C)One rate, every hour of the year. | $1,477 | — |
| Residential Service Three Phase (RS-40C)One rate, every hour of the year. | $1,677 | +$200 |
An estimate, not a quote. Supply charges move month to month, and your real usage pattern is not exactly this one. What it does show reliably is the gap between plans — both are priced off the same assumptions.
