Average Electric Bill in Mississippi

What the Average Electric Bill in Mississippi Actually Is

The average Mississippi household pays about $186.81 a month for electricity. That figure is the product of two numbers pulling hard in opposite directions: an average residential rate of 16.16 cents per kilowatt-hour as of May 2026, which is roughly 12 percent below the national average of 18.44 cents, and average consumption of 1,156 kilowatt-hours a month, which is about 34 percent above the national average of 863. Mississippi buys cheap electricity in unusually large quantities, and the quantity wins by a wide margin. The state's bill sits around 17 percent above the national average of $159.14.

The average is a bad description of almost any real household in the state. A 1,300-square-foot slab home in Hattiesburg in October, with the air conditioning off and the heat not yet on, may draw a third of that number. The same home in late July, or a manufactured home with electric resistance heat during a Delta cold snap in January, can run two or three times it. In much of Mississippi the gap between a household's cheapest month and its most expensive month is wider than the gap between two different states' annual averages.

Two things follow. First, a single monthly figure tells you nothing about whether your own bill is reasonable; you need your own kilowatt-hours and your own rate, which the electricity bill calculator will turn into a number you can actually check. Second, because the state's rate is already below the national average, nearly all of the difference between a high Mississippi bill and a low one is consumption. That is a more useful thing to know than it sounds, and the rest of this page is largely about why.

Why Electricity Costs About 16 Cents a Kilowatt-Hour Here

Mississippi is a fully regulated state. The utility that generates or buys your power is the same company that owns the poles and wires delivering it, and it charges a single bundled price approved by regulators. There is no competitive supplier market for residential customers, so the rate is not the outcome of shopping; it is the outcome of rate cases, fuel costs, and the physical shape of the system.

Generation is the largest reason the rate is low. Mississippi sits next to Gulf Coast natural gas production and the pipeline network that moves it, and gas-fired generation carries much of the load. The state also has nuclear capacity at Grand Gulf and a shrinking amount of coal. Cheap fuel, cheap land, and short distances between plants and load centers all push the generation component of the rate down.

What partly offsets that is delivery. Mississippi has low population density, and serving scattered rural customers requires more line-miles, more poles, and more vegetation management per meter than a compact urban system does. Storms compound it: hurricane restoration is genuinely expensive, and utilities recover it through storm reserves and, after larger events, long-term mechanisms that sit on bills for years.

Fuel itself moves separately from base rates through a fuel adjustment clause — a line item that passes the utility's actual fuel and purchased-power costs through to customers, usually with a lag of a month or a quarter. When gas prices spike, that clause is what puts the increase on your bill, and it does so without a rate case. Understanding which part of your bill is base rate and which is fuel is the difference between a complaint that goes somewhere and one that does not; the supply versus delivery guide walks through the split.

Why Mississippi Households Use 1,156 kWh a Month

Consumption, not price, is the Mississippi story. Several things stack on top of each other.

• The cooling season is long and the air is wet. An air conditioner in Mississippi is not only lowering temperature, it is removing moisture, and latent load — the energy spent condensing water out of humid air — is real work that never appears on a thermostat. Two houses at the same indoor temperature in Phoenix and in Jackson do not use the same electricity.
• Electric heat is common, and much of it is bad electric heat. Mississippi winters are short but not trivial. Where homes heat with electric resistance strips, or with a heat pump that falls back to those strips on a cold morning, a handful of January days can produce a bill that outruns August.
• Housing stock. Mississippi has a high share of manufactured and older site-built homes, many with modest insulation, single-pane glazing, and ductwork routed through vented attics or open crawlspaces. Leaky ducts in a 130-degree attic waste cooling before it ever reaches a room.
• Electric water heating is widespread, and water heating is typically one of the two or three largest single loads in a home.

Income interacts with all of it. Efficiency almost always costs money up front and pays back over years, which means the households facing the highest bills are frequently the ones least able to buy their way out. That is a structural reason state-level consumption stays high, and it is why Mississippi's bill runs above the national average despite a below-average price.

What You Can Actually Control Without a Retail Market

Mississippi households cannot shop for a supplier. There is no teaser rate to chase and no contract to sign, which removes an entire category of both opportunity and fraud. Every dollar you save here comes from using fewer kilowatt-hours or from moving when you use them, not from buying them cheaper.

The things that actually move a Mississippi bill, roughly in order of size:

• Stop paying for auxiliary heat you did not intend to buy. If you heat with a heat pump, deep overnight setbacks are counterproductive: recovering four or five degrees in the morning brings on the resistance strips, which cost far more per unit of heat than the heat pump itself. Steady setpoints beat aggressive swings.
• Seal and insulate the duct system before anything else. In a hot, humid climate with ducts outside the conditioned envelope, duct leakage is often the single largest waste in the house, and it is invisible.
• Attic insulation and air sealing, then windows only if they are failing. Window replacement is sold hard here and rarely pays back on energy alone.
• Water heater temperature and tank age. A heat pump water heater is one of the few appliance swaps large enough to see in a Mississippi bill.

Check your utility's efficiency and weatherization programs before paying retail for any of the above; income-qualified weatherization assistance exists here and covers work most households would never fund themselves. Budget billing is worth taking for cash-flow reasons, but be clear about what it does: it averages your annual cost across twelve payments and trues up later, reducing what you owe by nothing at all. The budget billing guide covers the true-up trap. And be skeptical of small-ball advice: if your lights are already LED, unplugging chargers and standby electronics will not produce a change you can detect against a 1,156 kWh baseline.

The Utilities Serving Mississippi and How They Differ

Three very different kinds of organization keep the lights on here, and the differences are structural rather than cosmetic.

Entergy Mississippi is an investor-owned utility regulated by the Mississippi Public Service Commission, serving a large swath of the western and central state including the Jackson area and the Delta. It participates in the MISO wholesale market, which means a share of its energy is dispatched and priced regionally rather than purely from its own plants, and it holds an interest in Grand Gulf nuclear capacity.

Mississippi Power, a Southern Company subsidiary, serves the southeastern counties including the Gulf Coast. It sits in the Southern electric system rather than MISO, is regulated by the same commission, and carries the state's most direct hurricane exposure — a fact that shapes both its storm reserve accounting and its capital spending on hardening.

The Tennessee Valley Authority is not a retail utility here at all. TVA is a federal power producer that sells wholesale to local power companies in north Mississippi — municipal systems and cooperatives — which then set retail rates locally. If you are served by one of them, your price is TVA's wholesale rate plus a local distributor component, your fuel adjustment comes from TVA's own monthly calculation, and your rates are not set by the state commission. Complaints go to a local board, not to Jackson.

Beyond those, member-owned electric cooperatives cover much of rural Mississippi. Co-ops are governed by boards elected by their own customers, who are technically members rather than ratepayers, and their rate-setting process looks nothing like an investor-owned rate case. Knowing which of these four categories you fall into determines who you petition, what public process exists, and whether your rate is even reviewable by the state.

The Arithmetic That Makes Mississippi Look Expensive

It is worth stating the central paradox plainly, because national coverage of electricity costs consistently gets Mississippi wrong. The state's price per kilowatt-hour is roughly 12 percent below the national average. Its monthly bill is roughly 17 percent above it. The entire gap, and then some, is volume: 1,156 kilowatt-hours against a national 863.

This means most of the standard advice aimed at high-bill states does not apply. Articles telling readers their rate is too high, or to switch suppliers, or to compare cents per kWh across states, describe a problem Mississippi does not have and a market that does not exist here. Rate comparison is not a lever available to a Mississippi household, and even if it were, the rate is not what is wrong.

The second consequence is about burden rather than arithmetic. When a state combines below-average household income with above-average bills, electricity absorbs a larger share of what people earn than the raw dollar figure suggests. A $186.81 bill is a different object in a household with $2,500 of monthly income than in one with $8,000. That is why disconnection policy, payment arrangements, and weatherization funding are consistently live issues in front of Mississippi's regulators — and the state's public service commissioners are elected rather than appointed, which makes those proceedings politically visible in a way they are not everywhere.

To compare where you sit against other states rather than against your neighbors, the national averages page carries the same three numbers for every state. The ranking changes dramatically depending on which of the three you sort by.
