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.
What does Entergy Mississippi LLC's residential rate cost?
Entergy Mississippi LLC files a single residential tariff, so there is no plan to choose between — everyone served here is on the same terms. That makes this page short on comparison and long on one question instead: what does that tariff actually do to a bill?
Priced hour by hour across a full year, a small apartment on this tariff comes to about $867 and a three-bedroom house with central air to about $1,296 — an effective 17.8¢ and 13.7¢ per kilowatt-hour once the fixed charge is spread across everything used.
With one plan and no hourly pricing, the only lever left is using less. Moving laundry or car charging to the middle of the night changes nothing here, which is worth knowing before you rearrange your evenings for no reason.
Expect the bill to swing with the weather rather than with anything you decide: the same house costs around $136 in July and $91 in February. Budget against the higher figure and the summer bill stops being a surprise.
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 125 utilities we cover, and Entergy Mississippi lands 33rd cheapest — in the cheaper half — at about $1,296 a year against a national median of $1,547. The range runs from $905 at Entergy Louisiana (Louisiana) to $5,089 at Ameren Illinois (Illinois).
The other two households sit in the same place: a small apartment pays about $867 here against a national median of $895, and the same house with an electric car charging overnight about $1,629 against $2,062. Effective rate, fixed charge included, is 13.7¢ per kilowatt-hour for the family home.

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.
