How Much Does It Cost to Charge a Subaru Solterra in Mississippi?

Quick Answer

Charging a 2026 Subaru Solterra at home in Mississippi costs approximately $42/month — that's $0.042/mile and saves $911/year compared to a 28 MPG gas car at Mississippi's gas price of $3.30/gallon.

SUVs balance cargo space with reasonable efficiency, making them the most popular EV body style in the U.S. — and this one handles that balance well. Hot climates can reduce EV range by 10–15% due to air conditioning load and battery thermal management. Pre-conditioning your battery while still plugged in minimizes this effect.

About the 2026 Subaru Solterra

The Subaru Solterra is a joint development between Subaru and Toyota (where it's sold as the bZ4X), bringing Subaru's legendary symmetrical all-wheel drive and outdoor-focused engineering to the EV market. 227 miles of range is modest, but Subaru's 4WD capability is genuine.

Advantages

✓Subaru Symmetrical AWD — engineered specifically for off-road and winter conditions

✓Familiar Subaru-ness with EyeSight driver assistance standard

✓Subaru's outdoor-brand identity and loyal following

✓Shared Toyota platform ensures engineering stability

Considerations

✗100 kW DCFC is slow — 10–80% takes approximately 56 minutes

✗227-mile range is the lowest of any new EV SUV in 2025

✗3.1 mi/kWh efficiency is average; the low range amplifies the gap vs. competitors

✗No single-motor/RWD version — AWD standard

Ideal Buyer

Subaru Outback and Forester loyalists who want AWD in an EV. Winter-climate buyers for whom Subaru AWD is a cultural requirement. Rural buyers who need genuine all-weather capability.

vs. Gas Equivalent

Direct EV equivalent of a Subaru Forester or Outback. Gas equivalent is approximately 28–30 MPG for the Subaru Outback.

EV Ownership in Mississippi

Mississippi has one of the lowest EV adoption rates in the US, but the state's $0.13/kWh electricity rate and relatively high gas prices create a compelling financial case for switching. Jackson and the Gulf Coast are the primary EV markets.

Incentives & Programs

Mississippi has no state EV tax credit. Federal incentives apply. Entergy Mississippi offers time-of-use plans. The low base electricity rate means EV economics are already favorable without additional incentives.

Charging Infrastructure

I-20 and I-55 corridors have limited DCFC coverage. Jackson has some urban charging. The Gulf Coast (Biloxi/Gulfport) is slightly better-served. Mississippi has among the sparsest DCFC networks in the Southeast — plan carefully.

Grid & Energy Source

Mississippi's grid is nearly all natural gas (~80%), with some nuclear from the Grand Gulf plant. The grid has a moderate carbon footprint for EV charging, slightly better than coal-heavy neighboring states.

MississippiElectricity Rates & EV Savings

The average residential electricity rate in Mississippi is $0.13/kWh, which is below the national average of $0.17/kWh. With a gas price of $3.30/gallon, Mississippi ranks as a favorable state for EV ownership.

Hot climates can reduce EV range by 10–15% due to air conditioning load and battery thermal management. Pre-conditioning your battery while still plugged in minimizes this effect. Your Subaru Solterra's 72 kWh battery provides up to 227 miles of EPA-rated range. Real-world range may vary by 10–30% depending on temperature, speed, and terrain.

Tips for Charging Your Subaru Solterra in Mississippi

Mississippi's hot climate and charging infrastructure have specific implications for Subaru Solterra owners. Here are practical tips to maximize range and minimize charging costs in this state:

Mississippi's heat and humidity require attention to battery thermal management — charge during cooler evening hours.

Plan DCFC stops carefully on I-20 and I-55 — coverage gaps of 80+ miles exist in some stretches.

Entergy Mississippi's off-peak rates make overnight home charging the economic sweet spot.

Jackson residents without garages: consider a Level 1 cable as a backup to public charging options downtown.
