In short: Most Charlotte homes buy power from Duke Energy Carolinas, which averaged 13.94¢ per kWh for homes in 2024 and whose North Carolina customers lost about 27 hours of power that year once major storms are counted, or under 3 hours without them (EIA). Mecklenburg County’s top risk is ice storms. Plan backup for winter, not just hurricanes.
This page covers what is local to the Charlotte area. For statewide rules (Duke Energy’s solar rates, licensing, the property tax exclusion), see our North Carolina energy guide.
Charlotte at a glance
- Duke Energy Carolinas: the main utility in Mecklenburg, Cabarrus and Iredell counties. Average home price 13.94¢/kWh in 2024. A typical 1,000 kWh monthly bill was $144.82 in January 2026 (NC Utilities Commission). Outages in 2024: 1,626 minutes per customer with major events, 168 minutes without them.
- City of Concord (city-owned): 11.84¢/kWh in 2024; 172 minutes of outages per customer, with no major-event days reported.
- Town of Huntersville (town-owned, part of town): 12.12¢/kWh in 2024; 239 minutes of outages per customer.
- Cooperatives: Union Electric Membership Corp. (13.37¢; 357 minutes with major events, 53 without) and EnergyUnited (11.54¢; 424 and 124 minutes) serve parts of the area.
- Sun: about 4.47 kWh per square meter per day in Charlotte (NASA POWER, 2001 to 2020). Our rough estimate: about 1,306 kWh a year per kW of panels.
- Top hazards (FEMA National Risk Index, Mecklenburg County): ice storms “Very High”; cold waves, hail, lightning, inland flooding, strong wind, tornadoes and winter weather “Relatively High”. Overall risk is “Relatively High”.
- Public charging: 966 public charging ports at 282 locations in Charlotte (777 Level 2, 189 DC fast), plus 105 in Concord, 45 in Mooresville, 39 in Huntersville and 32 in Matthews (AFDC, October 3, 2026).
Prices are each utility’s 2024 average (home revenue divided by home sales, EIA-861), so they include fixed charges and differ from the monthly statewide figure on our state page. Outage minutes are utility-wide in North Carolina, not Charlotte alone.
Your utility and what it means
Check the name on your bill first: the Charlotte area has an investor-owned utility, two town or city systems and two cooperatives, and the rules for solar, batteries and EV charging depend on which one you have.
- Duke Energy Carolinas: new solar customers go on Duke’s North Carolina solar rates, explained on our state page; the Net Metering Bridge rate closes to new applicants on December 31, 2026. For EV owners, Duke announced a Charger Prep Credit in 2022 of up to $1,133 per household toward the wiring for a Level 2 charger (not the charger itself). We could not confirm it is still open in 2026, so ask Duke before you count on it.
- City of Concord: its electric department requires solar to connect through a separate meter that carries only the solar system, caps home systems at 20 kW (AC), and requires an accessible disconnect next to that meter and liability insurance. Solar energy is credited under the City’s Renewable Energy Generation Rider, not Duke’s rates. Ask the City for the current credit before you size a system.
- Town of Huntersville, Union EMC and EnergyUnited: each sets its own solar and interconnection rules. Ask them directly what they credit for exported solar and whether any battery or EV program is open.
Backup power in Charlotte
Duke Energy Carolinas’ two 2024 numbers show the pattern: under 3 hours without power in an ordinary year, about 27 hours on average once major events are counted. 2024 included Hurricane Helene, which hit the mountains hardest, so the Charlotte average was likely lower. Charlotte’s own risk profile points somewhere else: FEMA rates ice storms “Very High” for Mecklenburg, Cabarrus, Iredell and Union counties. An ice storm brings down trees and lines across a whole metro at once, and the outage comes in the cold.
- For short outages (the normal year): a portable power station runs phones, a modem, lights, a CPAP and the fridge for a few hours.
- For an ice storm: plan for heat. Most heat pumps and gas furnaces need electricity for the fan and controls. A home battery can carry the furnace fan and essentials silently; a standby generator on natural gas runs for days.
- Safety: run portable generators outdoors only, at least 20 feet from the house, exhaust away from doors and windows, never in a garage (CPSC), and keep carbon monoxide alarms on every level. A transfer switch or interlock must be installed by a licensed electrician with a permit.
Compare the options in our backup power guide, size them with the generator sizing calculator and battery backup calculator, and read about standby generator installation.
Solar in Charlotte
A rough estimate: at about 1,306 kWh per kW per year, a 7 kW system would make roughly 9,100 kWh a year. If every kWh replaced Duke Energy Carolinas power at its 2024 average of 13.94¢, that would be worth about $1,270 a year. That is an upper bound: under Duke’s current solar rates, energy you export is credited at much less than retail, so the real value depends on how much you use (or store) yourself. In Concord, the separate solar meter means your value depends on the City’s generation credit, so get that number first.

Batteries
In the Charlotte area a battery earns its place two ways: it covers ice-storm and thunderstorm outages without fuel or noise, and on Duke’s time-of-use solar rate it lets you use your own midday solar in the evening instead of exporting it for a small credit. A battery without solar still works for backup. If you are on Concord, Huntersville or a cooperative, ask how they treat a battery before you buy. See home battery installation and home battery cost.
EV charging
Charlotte has the most public charging of any city on our North Carolina list: 966 ports, 189 of them DC fast. Home charging is still the cheap option. A labelled estimate at about 30 kWh per 100 miles: about $4.18 per 100 miles at Duke Energy Carolinas’ 2024 average price (about $500 a year for 12,000 miles), or about $3.55 per 100 miles on Concord’s 2024 average.
Drive on another fuel? See every alternative fuel station in Charlotte: hydrogen, propane, natural gas, E85 ethanol, biodiesel and renewable diesel.
A Level 2 charger needs a 240-volt circuit, a licensed electrician and usually a permit. The federal 30C charger credit ended for chargers placed in service after June 30, 2026. See EV charger installation and our EV charging cost calculator.
Permits and inspections
- Charlotte, Huntersville, Matthews (Mecklenburg County): Mecklenburg County Code Enforcement issues building and electrical permits. Residential solar applications go through its AccelaMeck portal, and it publishes a user guide for residential solar applications.
- Concord (Cabarrus County): Cabarrus County Construction Standards handles building permits and inspections across the county; the City of Concord reviews zoning. Solar also needs the City electric department’s interconnection approval if Concord is your utility.
- Mooresville: the Town of Mooresville Building Permitting & Inspections department has handled permits in the town and its planning area since September 2023, and publishes solar permitting guidance.
- Who does the work: solar of any size needs a licensed electrical contractor in North Carolina; generator gas lines need a licensed plumbing or gas contractor. Many Charlotte-area subdivisions have HOAs, so check their approval rules early.

Charlotte energy FAQ
Who is my electric company in Charlotte?
Most of Charlotte is served by Duke Energy Carolinas. Around it, the City of Concord and the Town of Huntersville run their own electric systems, and Union EMC and EnergyUnited, both cooperatives, serve parts of Mecklenburg, Cabarrus, Union and Iredell counties. Your bill tells you which one you have, and that decides your solar and EV rules.
How long are power outages in Charlotte?
Duke Energy Carolinas’ North Carolina customers averaged 168 minutes without power in 2024 without major events, and 1,626 minutes (about 27 hours) with them, a year that included Hurricane Helene (EIA). Those are utility-wide averages. FEMA rates ice storms “Very High” for Mecklenburg County, so winter outages deserve a plan.
Can I put solar on my roof in Concord?
Yes, if Concord’s electric department approves the connection. Its rules call for a separate meter that carries only the solar system, a 20 kW (AC) limit for homes, a lockable disconnect next to that meter and liability insurance. The building permit comes from Cabarrus County. Ask the City what its Renewable Energy Generation Rider pays before you size the system.
Where do I get a solar or generator permit in Charlotte?
From Mecklenburg County Code Enforcement, which issues building and trade permits for Charlotte and the county’s towns, including Huntersville and Matthews. Your licensed contractor normally applies. Mooresville has its own town permit office, and Concord’s building permits come from Cabarrus County.
Does Duke Energy help pay for a home EV charger in Charlotte?
Duke announced a North Carolina Charger Prep Credit in 2022 of up to $1,133 per household toward the wiring for a Level 2 charger. We could not confirm that it is still open in 2026, so ask Duke Energy before your electrician starts. The federal 30C charger credit has ended for chargers placed in service after June 30, 2026.
