Gulf Coast MS Energy Guide: Solar, Batteries, Backup Power, EV

In short: The Mississippi Gulf Coast has some of the steadiest power in the state but the biggest storm risk. Mississippi Power customers lost about 124 minutes of power in 2024, a fraction of the state’s 567, yet FEMA rates hurricanes and lightning “very high” in Harrison County. Power cost about 13.5¢ to 14.5¢ per kWh.

This page covers Gulfport, Biloxi and Ocean Springs. Three utilities serve the coast under different rules, so check your bill first. For statewide rules, contractor licensing and averages, see our Mississippi energy guide.

Gulf Coast at a glance

• Mississippi Power: serves much of Gulfport, Biloxi and Ocean Springs. About 14.47¢ per kWh for homes (2024 average); 124 minutes without power per customer counting major events, 82 on normal days, about 1.1 interruptions (EIA-861, 2024).
• Coast Electric Power Association: a co-op serving Harrison, Hancock and Pearl River counties; about 13.81¢; 277 minutes with major events, 103 without.
• Singing River Electric Cooperative: serves parts of Harrison and Jackson counties, including around Ocean Springs; about 13.46¢; 243 minutes with major events, 169 without (reported under a different standard).
• Sun: 4.74 kWh per square meter per day in Gulfport (NASA POWER, 2001 to 2020), about 1,385 kWh a year per kW of panels by our rough estimate, the strongest of our Mississippi metros and the mildest in December.
• Top hazards: hurricanes and lightning rated “very high” in Harrison County, with coastal flooding, strong wind and tornadoes “relatively high”; Jackson County rates coastal flooding, hurricanes and lightning “relatively high” (FEMA National Risk Index).
• Public charging: 35 public ports in Gulfport and 16 in Biloxi (AFDC, October 3, 2026).

Your utility and what it means

Mississippi Power. Exports earn the Public Service Commission’s credit (the utility’s avoided cost plus a 2.5¢ adder, more for low-income customers; see the state page). Its renewable energy page limits home systems to 20 kW or 110% of your peak demand in the previous calendar year, whichever is less, and requires an interconnection agreement before you connect. Mississippi Power says more than 96% of its customers are on a “self-healing” network that isolates faults automatically, and that it is replacing wooden poles with concrete and steel and raising substations above flood levels. It has no EV charging rate yet, though it says it plans one.

Coast Electric. Coast offers a renewable energy rate with no panels on your roof: members can buy up to 4 kW of solar capacity at $18.10 per kW per month, and each kW is expected to produce about 164 kWh a month, which is subtracted from your usage. Supply is limited at first. If you want rooftop panels instead, Coast requires a contractor registered as a solar contractor in Mississippi and does not connect self-installed systems.

Singing River. Singing River says the PSC’s distributed generation rules do not apply to it, because its members regulate its rates through its board. Members can still connect solar and sell excess power to Cooperative Energy, its wholesale supplier, which pays “the value of the electricity”. Ask Singing River for the current buyback rate in writing (its explanation).

Backup power on the Gulf Coast

Day to day, coastal power is reliable: Mississippi Power customers averaged about one interruption in 2024. The risk is the rare big storm. A hurricane can bring wind, storm surge and flooding at once, and outages after a direct hit can last far longer than any 2024 average suggests. Plan for that case:

• Hurricane outages: a standby generator on natural gas or propane, or a portable unit with a transfer switch, is the practical answer for several days without power. Size it with the generator sizing calculator.
• Flooding: place a standby generator, battery and inverter above the flood level your building official requires, and secure fuel tanks.
• Short summer outages from lightning and storms: a home battery or a portable power station keeps fans, fridge and internet going. Compare options in backup power.

After a hurricane, generator carbon monoxide is a known killer. Run a generator outdoors only, at least 20 feet from the house, never in a garage or under a raised house, with CO alarms on each level. Never backfeed through an outlet; a licensed electrician should install a transfer switch. Read generator installation.

Solar on the Gulf Coast

Each kW of panels makes about 1,385 kWh a year in Gulfport by our estimate. Used at home in place of grid power, that is worth about $200 a year on Mississippi Power, $191 on Coast Electric and $186 on Singing River at 2024 prices; exports earn much less. These are estimates, not promises. On Coast’s renewable rate, 164 kWh a month at about 13.8¢ is worth roughly $22.65 against the $18.10 charge, so a rough saving of about $4.50 per kW each month before fixed charges.

Roof panels here must stand up to hurricane winds: Ocean Springs, for example, builds homes to a 160 mph wind-load requirement, so ask installers about mounting and roof attachment, and check your homeowner’s insurance. Grid-tied panels shut off in an outage unless paired with a battery. Try the solar potential calculator and read solar costs and solar installation.

Home batteries on the Gulf Coast

A battery keeps essentials running through routine outages and stores midday solar for the evening instead of exporting it. After a hurricane, solar plus a battery can recharge each day if the panels survive, but most households will still want a generator for the first days. Mount equipment above flood level. See battery installation, home battery cost and the battery backup calculator.

EV charging on the Gulf Coast

Public charging is limited to 35 ports in Gulfport and 16 in Biloxi, so home charging matters most. At about 30 kWh per 100 miles, 100 miles cost about $4.35 on Mississippi Power, $4.15 on Coast Electric and $4.05 on Singing River at 2024 prices (estimates). Charge fully before a storm in case you need to evacuate. A Level 2 charger needs a 240-volt circuit and a permit: see EV charger installation and the EV charging cost calculator.

Permits and inspections

• Gulfport: Building Code Services handles plan review, permits and inspections and publishes minimum submission criteria for residential permits.
• Biloxi: the Department of Community Development covers building permits, inspections and floodplain management.
• Ocean Springs: the Building Department issues electrical permits; homes are built to the 2018 International Residential Code with a 160 mph wind-load requirement and the 2017 National Electrical Code.
• Outside city limits: ask Harrison or Jackson County.

Mississippi has no statewide electrician license, so ask the city what it requires (state contractor lookup on the Mississippi page). If your home is in a flood zone, ask about floodplain rules for equipment placement before you buy.

Gulf Coast energy FAQ

Is power on the Mississippi Gulf Coast reliable?

In normal years, yes. Mississippi Power customers averaged 124 minutes without power in 2024 including major events, against 567 statewide (EIA-861). The big risk is a hurricane: FEMA rates hurricane risk very high in Harrison County.

Can I get solar on the coast without putting panels on my roof?

Coast Electric members can buy up to 4 kW of solar capacity at $18.10 per kW per month. Each kW is expected to produce about 164 kWh a month, which is subtracted from your usage. Supply is limited, so ask Coast Electric about availability.

Does Singing River Electric offer net metering?

Not under the PSC rules. Singing River says those rules do not apply to it because its members regulate its rates. Members can connect solar and sell excess power to Cooperative Energy at the value of the electricity, so ask for the current rate in writing.

Where should a generator go in a flood-prone home?

Above the flood level your building official requires, on a secure pad, and at least 20 feet from doors and windows. Ask Gulfport, Biloxi or Ocean Springs about floodplain rules before installing.
