How Entergy Mississippi’s plans work

RS-40C (Residential Service). In July the first 500 kWh a month cost 12.8¢ each; then 12.0¢ above 500 kWh a month. An average Mississippi home (1,569 kWh in July) goes past the first tier, so extra load such as an EV is priced higher. Fixed charge: $41.01 a month.

Prices on this page are all-in per kWh, before taxes: base rates, supply and every per-kWh rider in the utility’s current tariff sheets. Your bill shows them as separate lines, and riders can change between tariff revisions.

As a cross-check, Entergy Mississippi billed its residential customers an average of 13.21¢ per kWh in 2024 (revenue ÷ sales, EIA-861). A plan taken from URDB is shown only if its all-in price is consistent with that figure, adjusted for Mississippi’s price change since.
