In short: Charleston is Appalachian Power country, and in 2024 Appalachian Power’s West Virginia customers lost about 1,832 minutes of power each, more than 30 hours, well above the state average. Homes paid about 16.77¢ per kWh. FEMA rates Kanawha County’s overall risk “Relatively High”, so backup power comes first here.
This page covers Charleston, South Charleston and the rest of Kanawha County. Statewide rules (the new solar export credits and who keeps retail credit, licensing, why we could not confirm state solar tax breaks) are on our West Virginia energy guide.
Charleston at a glance
- Appalachian Power (most of Kanawha County): 16.77¢/kWh average for homes in 2024; outages 1,832 minutes per customer with major events and 576 without, with about 3.3 interruptions a year (EIA-861, West Virginia service area).
- Black Diamond Power (a small private utility in parts of Kanawha and nearby counties): 15.35¢/kWh; outage minutes not reported to EIA.
- Sun: about 3.94 kWh per square meter per day at Charleston (NASA POWER, 2001 to 2020). Our rough estimate: about 1,150 kWh a year per kW of panels.
- Top hazards (FEMA National Risk Index): Kanawha County’s overall risk is “Relatively High”; lightning, river flooding, strong wind and winter weather are “Relatively High”, with ice storms, landslides, hail and heat waves “Relatively Moderate”.
- Public charging: 36 ports at 11 locations in Charleston and 9 in South Charleston (AFDC, October 3, 2026).
For comparison, the statewide average in 2024 was 1,166 minutes with major events and 486 without. Prices are 2024 averages including fixed charges; the state average was 15.78¢ in July 2026.
Your utility and what it means
- Outages are the headline. Even leaving out major storm days, an Appalachian Power customer in West Virginia averaged about 9.6 hours without power in 2024, and with them about 30 hours. That is the strongest local case for backup in this guide.
- Solar credits: Appalachian Power’s one-to-one net metering has ended for new customers, with a reported credit of about 12.4¢ per kWh for exports; existing customers were grandfathered (details and caveats on our state page). For a new system, contact Appalachian Power’s West Virginia distributed generation coordinator (dgcoordinator-wv@aep.com, 304-348-4126) before you sign (Appalachian Power solar).
- EV off-peak rate: Appalachian Power’s West Virginia Off-Peak Charging (Tariff RS-PEV) prices home charging about 25% lower from 8 p.m. to 6 a.m. on weekdays and all day on weekends and major holidays. Its example shows 12.9¢ off-peak against 17.6¢ standard; charging on-peak adds 5.11¢ per kWh. Sign-up is free, and Appalachian Power supplies the extra meter base and EV meter, but you pay an electrician to install the meter base, and it must pass inspection (Appalachian Power WV off-peak charging).
- Solar plus EV rate: Appalachian Power’s FAQ notes that net metering rules do not currently allow time-of-use metering on its standard supply tariff, so if you have or plan net-metered solar, ask how the EV rate would work for your account.
- Charger rebates: Appalachian Power’s site still links to a West Virginia EV charger rebate, but the link now leads to its TakeCharge home programs list, which shows no charger rebate. We found none current.
Backup power in Charleston
With roughly 3.3 interruptions and many hours without power in a typical recent year, Charleston households use backup, not just own it. Kanawha County’s hazards point the same way: strong wind, lightning and winter weather knock lines down, and river flooding along the Kanawha and Elk adds a second reason to think about where equipment sits.
- Standby generator: starts on its own and runs for days on natural gas or propane; the hands-off choice for frequent long outages. A licensed electrician installs the automatic transfer switch.
- Home battery: covers the many shorter outages silently; for multi-day storms pair it with solar or a generator.
- Portable generator or power station: the budget route. Generators outdoors only, at least 20 feet from the house, exhaust away from doors and windows, never in a garage or basement (CPSC), with carbon monoxide alarms on every level and a transfer switch or interlock installed by a licensed electrician.
- Near the river: unincorporated Kanawha County runs a floodplain program; mount generators, batteries and inverters above expected flood levels.
Size your system with the generator sizing calculator or the battery backup calculator; read our backup power guide, generator installation and portable power.
Solar in Charleston
A rough estimate: a 7 kW system at about 1,150 kWh per kW makes roughly 8,060 kWh a year. If you used all of it at home at 16.77¢, it would be worth about $1,350 a year; if half went to the grid at the reported credit of about 12.4¢, about $1,180. On hillside lots, slopes and trees can shade a roof for part of the day, so get a site-specific estimate. Try the solar potential calculator, then read solar panel cost and solar installation.
Batteries
Batteries make double sense on Appalachian Power: they ride through frequent outages, and with exports credited below retail, storing midday solar for the evening is worth more than sending it out. Of the 1,592 net-metered home solar systems on Appalachian Power’s West Virginia lines at the end of 2024, 248, about one in six, had a battery (EIA). See home battery installation and home battery cost.
EV charging
A labelled estimate at 30 kWh per 100 miles: about $5.03 per 100 miles at the 2024 average of 16.77¢ (roughly $600 a year for 12,000 miles), or about $3.87 per 100 miles (roughly $460 a year) at the 12.9¢ off-peak price in Appalachian Power’s example. Hills and cold weather raise use. A Level 2 charger needs a 240-volt circuit, an electrical permit in the city and a licensed electrician. See EV charger installation and the EV charging cost calculator.

Permits and inspections
- City of Charleston: all construction work needs a permit before work begins, including electrical, plumbing, HVAC and tank work. Apply to the Permit Coordinator, Building Department, 915 Quarrier St., Suite 5 (Permit Office 304-348-6833). Homeowners may do their own work with a permit and inspection, and construction permit fees are waived for jobs up to $2,500 (Charleston permits).
- Unincorporated Kanawha County: the county’s Planning and Development department handles building permits, zoning and floodplain management ((304) 357-0570) (Kanawha County Planning).
- South Charleston and other towns: ask the town’s building office.
- Who does the work: a licensed electrician and a licensed contractor (lookups on our state page), a qualified gas fitter for generator fuel lines, Appalachian Power’s interconnection approval for solar or batteries, and HOA approval where needed.

Charleston energy FAQ
How often does the power go out in Charleston?
EIA’s 2024 figures for Appalachian Power in West Virginia show about 3.3 interruptions per customer and about 1,832 minutes without power including major storms, or 576 minutes on ordinary days. Both are above the state averages, so plan for several outages a year.
Does Appalachian Power have a cheaper rate for EV charging?
Yes. Its West Virginia Off-Peak Charging rate saves about 25% when you charge from 8 p.m. to 6 a.m. on weekdays or any time on weekends and major holidays. You need a smart (AMI) meter and an electrician to install a second meter base, which must pass inspection.
Do I need a permit for a generator transfer switch in Charleston?
Yes. The city requires a permit for all construction work, including electrical work, before it starts. Homeowners may pull their own permit and pass inspection, but a licensed electrician is the safer choice for a transfer switch.
Is solar still worth it on Appalachian Power?
It can be, but less from exports than before. By our rough estimate a 7 kW system is worth about $1,180 to $1,350 a year depending on how much you use yourself. Adding a battery raises self-use and gives backup in an area with frequent outages.
