Going electric in Mississippi

Electricity, EV charging and solar in Mississippi

A typical Mississippi household could keep about $3,740 a year by going electric. Charging a car at home here is like paying $1.20 a gallon instead of $3.85, and solar panels sized for an average home could cover up to $155 of the monthly bill.

What it costs to charge an EV in Mississippi

Home charging cost is simply the electricity price times how much energy the car uses. The table uses EPA ratings, which already include the energy lost while charging. At 15.2¢/kWh, charging in Mississippi costs 16% less than the national average.

Gasoline car, 25.5 mpgregular at $3.85/gal (Gulf Coast regional average)$15.10$151

On these averages, a compact electric SUV charged at home saves about $104 a month in fuel over a 1,000-mile month compared with a 25.5 mpg gasoline car. Many utilities offer cheaper overnight EV rates that can cut these figures substantially. Try your own numbers in the EV charging cost calculator.

Public charging in Mississippi

The Department of Energy lists 707 public charging ports at 224 locations in Mississippi, including 349 DC fast-charging ports and 358 Level 2 ports. That is roughly one public port for every 1,896 residential electricity customers. Find live locations on the AFDC station locator.

How much solar a typical Mississippi home needs

The PVWatts solar model from the National Laboratory of the Rockies (formerly NREL), run on ten years of NASA hourly weather data for Jackson, estimates each kilowatt of south-facing panels at a 20° tilt produces 1,399 kWh a year. To cover the average Mississippi household's 13,871 kWh a year you would need about 9.9 kW, or roughly 25 panels at 400 watts each.

If every kilowatt-hour from the panels replaced one bought at 15.2¢, each kilowatt of panels would be worth about $213 a year. Under that best case, a system installed for $2.13 per watt would pay for itself in 10 years, and one at $4.25 per watt in 20 years.

That is an upper bound. Many utilities credit exported solar at less than the retail rate, so the value depends heavily on your utility's net metering or net billing rules and how much power you use while the sun is up. Compare any installer quote's price per watt against these break-even figures.

Home battery backup in Mississippi

The average Mississippi home uses about 38.0 kWh a day. A single 13.5 kWh battery (the capacity of a Tesla Powerwall 3) would run that average load for about 9 hours; backing up only essentials such as the fridge, lights, internet and a furnace fan stretches that much further. Covering a full day of average use would take about 2.8 batteries of that size. Size a battery for your home, compare whole-home and portable backup or see the best portable power stations.

Incentives in Mississippi

The federal $7,500 new-EV and $4,000 used-EV tax credits ended for vehicles acquired after 30 September 2025, and the 30% homeowner credit for solar and batteries ended for expenditures after 31 December 2025.

Frequently asked questions

How much does it cost to charge an electric car at home in Mississippi?

At Mississippi's average residential price of 15.2¢ per kWh (January–July 2026, EIA), a 2026 Chevrolet Equinox EV FWD rated at 31.1 kWh per 100 miles costs about $4.72 per 100 miles, or about $47 for 1,000 miles. Your own cost depends on your utility's rate plan and when you charge.

Is it cheaper to drive an EV than a gas car in Mississippi?

On average prices, yes for most drivers. With regular gasoline at $3.85 a gallon (Gulf Coast regional average, EIA) and a 25.5 mpg car, fuel costs about $15.10 per 100 miles, versus about $4.72 for the compact electric SUV above charged at home. Public fast charging usually costs more than home charging and narrows the gap.

How many solar panels does an average Mississippi home need?

The average Mississippi household used 1,156 kWh a month in 2024 (EIA). Our PVWatts model estimates 1 kW of south-facing panels near Jackson produces about 1,399 kWh a year, so covering all of that use takes about 9.9 kW — roughly 25 panels of 400 watts. Shading, roof direction and your own usage change the answer.

How big a home battery would an average Mississippi home need?

An average Mississippi home uses about 38.0 kWh a day. One 13.5 kWh battery such as a Tesla Powerwall 3 would cover about 9 hours of average use, and longer if you only back up essential circuits.

Estimates only. Your actual costs depend on your utility's rate plan, how and when you charge or use power, and local prices. This is general information, not financial, tax or legal advice. See our disclaimer.
