In short: New Braunfels has about 116,500 people and sits in Comal County. City of San Antonio, Pedernales Electric Coop, Inc and Guadalupe Valley Elec Coop Inc serves different parts of Comal County, so your utility depends on your address; their 2024 home averages range from 12.22¢ to 12.49¢ per kWh (EIA). FEMA rates Comal County river and heavy-rain flooding “relatively high”. Rooftop solar here makes roughly 1,410 kWh a year per kW of panels by our estimate, which is good for solar.
This page covers what is local to New Braunfels: its utility, outage records, sunshine, weather risks and charging. Statewide rules such as net metering, incentives and electrician licensing are in our Texas energy guide and the wider area is covered in the San Antonio guide.

Your utility and what it means
City of San Antonio is a city-owned utility and served about 865,914 home customers in 2024; its 12.43¢ average was below the 15.88¢ statewide average for July 2026. Pedernales Electric Coop, Inc is a member-owned cooperative utility and served about 405,587 home customers in 2024; its 12.22¢ average was below the 15.88¢ statewide average for July 2026. Guadalupe Valley Elec Coop Inc is a member-owned cooperative utility and served about 92,189 home customers in 2024; its 12.49¢ 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, Guadalupe Valley Elec Coop Inc reported 132 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 New Braunfels
- River and heavy-rain flooding (relatively high): Heavy rain can flood basements and take out power. Put sump pumps on backup power and keep equipment above the flood line.
- 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 New Braunfels 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 New Braunfels
By our rough estimate each kW of panels makes about 1,410 kWh a year in New Braunfels (NASA sunshine data times 365 days times 0.80 for system losses). Valued at City of San Antonio’s 2024 average of 12.43¢, that is about $175 a year per kW if all of it offsets your own use (an estimate, not a promise). Production swings with the seasons: July is the sunniest month at 6.69 and December the dimmest at 2.80, 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. New Braunfels has 61 public charging ports in the federal station list including 56 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 New Braunfels building or permitting department, or from Comal County if you live outside city limits, and often a utility interconnection approval. We have not verified a local permit page for New Braunfels, 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.

New Braunfels energy FAQ
Who is my electric company in New Braunfels?
City of San Antonio, Pedernales Electric Coop, Inc and Guadalupe Valley Elec Coop Inc all serve parts of Comal County. Which one serves you depends on your street, so check the top of your bill. Their 2024 home price averages differ (City of San Antonio 12.43¢, Pedernales Electric Coop, Inc 12.22¢, Guadalupe Valley Elec Coop Inc 12.49¢) so it matters for solar math.
How much power will solar make in New Braunfels?
About 1,410 kWh a year per kW of panels by our estimate, so a 6 kW system would make roughly 8,460 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 Comal 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 New Braunfels?
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.
