In short: Alabaster has about 34,500 people and sits in Shelby County. Alabama Power Co and Coosa Valley Electric Coop Inc serves different parts of Shelby County, so your utility depends on your address; their 2024 home averages range from 15.71¢ to 16.77¢ per kWh (EIA). FEMA rates Shelby County tornadoes “relatively high”. Rooftop solar here makes roughly 1,310 kWh a year per kW of panels by our estimate, which is good for solar.
This page covers what is local to Alabaster: its utility, outage records, sunshine, weather risks and charging. Statewide rules such as net metering, incentives and electrician licensing are in our Alabama energy guide and the wider area is covered in the Birmingham guide.

Your utility and what it means
Alabama Power Co is an investor-owned utility and served about 1,332,911 home customers in 2024; its 16.77¢ average was close to the 16.4¢ statewide average for July 2026. Coosa Valley Electric Coop Inc is a member-owned cooperative utility and served about 15,612 home customers in 2024; its 15.71¢ average was below the 16.4¢ statewide average for July 2026. Those are utility-wide averages, not a quote for your address; your own bill is the real number.
For reliability, Coosa Valley Electric Coop Inc reported 155 minutes per customer without major storms in 2024, more than the statewide figure of 118 (EIA-861). Utility-wide numbers hide a lot: a home at the end of a long rural line usually has more outages than the average.
Net metering, export rates and incentives are set at state level and by each utility. Start with the Alabama guide and then ask your utility for its current interconnection steps before you sign anything.
Backup power in Alabaster
- Tornadoes (relatively high): Tornado-season storms cut power quickly. A battery that switches on by itself, or a portable generator ready to go, covers the first night; sirens and weather radios need power too.
- Lightning (relatively high): Lightning causes short outages and damages electronics. Surge protection and a battery that switches over automatically protect the things you care about.
- Short outages: a portable power station covers phones, Wi-Fi, a CPAP and lights; a home battery switches over automatically.
Size your setup with the generator sizing tool and the battery backup calculator, and compare options in backup power. Generator safety (CPSC): outdoors only, at least 20 feet from the house, exhaust away from doors and windows, never in a garage, and battery-powered carbon monoxide alarms inside. A licensed electrician should install any transfer switch, with a permit; see generator installation.
Solar in Alabaster
By our rough estimate each kW of panels makes about 1,310 kWh a year in Alabaster (NASA sunshine data times 365 days times 0.80 for system losses). Valued at Alabama Power Co’s 2024 average of 16.77¢, that is about $220 a year per kW if all of it offsets your own use (an estimate, not a promise). Production swings with the seasons: June is the sunniest month at 6.20 and December the dimmest at 2.30, a 2.7-to-1 gap.
Check your own roof with the solar potential tool, see solar costs and net metering vs net billing, and read the steps in solar installation. Hail and storm exposure are worth raising with installers and your insurer.
Batteries and EV charging
A home battery earns its place when outages are frequent, when your utility pays little for exported solar, or when evening prices are high; compare in home batteries and battery costs. Alabaster has 20 public charging ports in the federal station list including 20 DC fast, but home charging is cheaper and easier: see the EV charging cost calculator and EV charger installation.

Permits and inspections
Solar, generator transfer switches and EV chargers normally need an electrical permit from the Alabaster building or permitting department, or from Shelby County if you live outside city limits, and often a utility interconnection approval. We have not verified a local permit page for Alabaster, so check the city and county websites or ask your electrician, who will know the process. Hire only a licensed electrician or installer; the Alabama guide lists the state licensing rules.

Alabaster energy FAQ
Who is my electric company in Alabaster?
Alabama Power Co and Coosa Valley Electric Coop Inc both serve parts of Shelby County. Which one serves you depends on your street, so check the top of your bill. Their 2024 home price averages differ (Alabama Power Co 16.77¢, Coosa Valley Electric Coop Inc 15.71¢) so it matters for solar math.
How much power will solar make in Alabaster?
About 1,310 kWh a year per kW of panels by our estimate, so a 6 kW system would make roughly 7,860 kWh. Shade, roof direction and tilt change this; run your address through the solar potential tool for a better number.
Is a generator or a battery better for tornadoes in Shelby County?
It depends how long the outage lasts. A battery is quiet, automatic and good for short outages and for pairing with solar; a standby generator keeps going as long as it has fuel, which suits multi-day events. Many homes use a battery for everyday outages and add a generator for the rare long one.
Do I need a permit for solar or a generator in Alabaster?
Almost always an electrical permit for a transfer switch, solar or an EV charger, issued by the city or county where you live. Your licensed electrician or installer normally pulls it. Never connect a generator to your house wiring without a transfer switch.
