Your utility and what it means
Concho Valley Elec Coop Inc is a member-owned cooperative utility and served about 12,060 home customers in 2024; its 12.73¢ average was below the 15.88¢ statewide average for July 2026. Southwest Texas Elec Coop, Inc is a member-owned cooperative utility and served about 5,886 home customers in 2024; its 13.55¢ average was below the 15.88¢ 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, Concho Valley Elec Coop Inc reported 390 minutes per customer without major storms in 2024, more than the statewide figure of 129 (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 Texas guide and then ask your utility for its current interconnection steps before you sign anything.
Backup power in San Angelo
- Drought (relatively high): Drought raises fire and heat risk and strains wells. If you rely on a well pump, include it in your backup plan.
- Hail (relatively high): Hail is hard on rooftop solar; ask installers about impact-rated panels and your insurer about coverage.
- Cooling load: an outage in San Angelo summer means no air conditioning. A central unit is a big load; a large battery system or standby generator can run it, while a smaller setup keeps fans, a window unit or a mini-split going.
- 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 San Angelo
By our rough estimate each kW of panels makes about 1,530 kWh a year in San Angelo (NASA sunshine data times 365 days times 0.80 for system losses). Valued at Concho Valley Elec Coop Inc’s 2024 average of 12.73¢, that is about $195 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 7.29 and December the dimmest at 3.03, a 2.4-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. San Angelo has 32 public charging ports in the federal station list including 16 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 San Angelo building or permitting department, or from Tom Green County if you live outside city limits, and often a utility interconnection approval. We have not verified a local permit page for San Angelo, so check the city and county websites or ask your electrician, who will know the process. Hire only a licensed electrician or installer; the Texas guide lists the state licensing rules.

San Angelo energy FAQ
Who is my electric company in San Angelo?
Concho Valley Elec Coop Inc and Southwest Texas Elec Coop, Inc both serve parts of Tom Green County. Which one serves you depends on your street, so check the top of your bill. Their 2024 home price averages differ (Concho Valley Elec Coop Inc 12.73¢, Southwest Texas Elec Coop, Inc 13.55¢) so it matters for solar math.
How much power will solar make in San Angelo?
About 1,530 kWh a year per kW of panels by our estimate, so a 6 kW system would make roughly 9,180 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 winter weather in Tom Green 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.
Can solar and a battery run my air conditioner during an outage?
Yes if the system is sized for it. A central air conditioner needs a large battery or generator, so many people back up one room or a mini-split instead. Use the battery backup calculator to see the runtime for your appliances.
Do I need a permit for solar or a generator in San Angelo?
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.
