In short: Columbia runs its own electric utility, Columbia Water & Light, which reported about 35 outage minutes per home in 2024 at about 13.9 cents per kWh (EIA). Jefferson City is on Ameren Missouri, and co-ops serve the countryside. FEMA rates ice storms, winter weather and tornadoes “relatively high” in Boone County.
This page covers mid-Missouri: Columbia, Jefferson City and the surrounding Boone and Cole counties. Statewide rules on net metering, licensing and incentives are in our Missouri energy guide.
Columbia at a glance
- Columbia Water & Light: city-owned; about 13.9¢ per kWh for homes, averaged over 2024; 35 minutes without power per customer and about one interruption every two years, as reported to EIA (EIA-861, 2024).

- Sun: about 4.2 kWh per square meter a day (NASA POWER, 2001 to 2020), or roughly 1,240 kWh a year per kW of panels by our estimate.
- Top hazards: Boone County is “relatively high” for cold waves, ice storms, lightning, strong wind, tornadoes and winter weather; Cole County for ice storms and winter weather (FEMA National Risk Index, December 2025).
- Public charging: 63 ports in Columbia and 40 in Jefferson City (AFDC data, October 3, 2026).
Prices above are 2024 averages across all months. Missouri’s summer prices run higher; see the state guide for July 2026 figures.
Your utility and what it means
Mid-Missouri is a patchwork of city, investor-owned and co-op utilities, and the lines are not always obvious, so check the name on your bill before you get solar quotes. That utility sets the application steps and approves the connection.
- Columbia Water & Light: as a city utility it writes its own solar rules within Missouri law. It publishes interconnection and net metering application guidelines and information on solar loans; start with the city’s getting started with solar page. We could not load the city’s website on October 3, 2026, so we do not quote its credit rates or loan terms here; read them before signing. EIA counted 552 Columbia homes with net-metered solar in 2024, one of the higher counts among Missouri’s city utilities.
- Ameren Missouri: in Jefferson City, net metering follows Missouri’s statewide rules: monthly netting at the full rate, with any monthly surplus credited at a lower avoided-cost rate. Ameren’s solar rebate has ended. Check Ameren’s net metering page for current details.
- Boone Electric, Three Rivers and Co-Mo: each co-op has its own interconnection process. Boone Electric had 330 net-metered solar homes in 2024 and Co-Mo 229, 18 of them with batteries (EIA). Ask your co-op before you design a system.
Backup power in Columbia
Inside Columbia, everyday outages are rare by EIA’s figures, though the city reports them by hand rather than through automatic meters, so treat the number as a guide. Outside the city, co-op and Ameren customers saw two to two and a half hours of outages in 2024. The shared risk is winter: FEMA rates ice storms and winter weather “relatively high” in both Boone and Cole counties, and Boone also for tornadoes and strong winds. An ice storm can cut power for days anywhere in the region.
A portable power station or a small home battery can keep a gas furnace fan, the fridge, lights and Wi-Fi running for some hours. For days without power, a generator on natural gas or propane is the usual answer, especially on rural co-op lines. Compare them in backup power options, and size yours with the generator sizing tool or the battery backup calculator.
Safety: the U.S. Consumer Product Safety Commission says to run a generator outdoors only, at least 20 feet from the house, with exhaust away from windows, doors and vents, never in a garage. Install battery-backed carbon monoxide alarms. A licensed electrician should install the transfer switch or interlock; see generator installation.
Solar in Columbia
At about 1,240 kWh a year per kW, each kW of panels would offset roughly $175 a year at Columbia Water & Light’s 2024 average price, about $165 on Boone Electric and about $155 on Ameren in Jefferson City (estimates, assuming all of it replaces power you would buy). A 6 kW system on Columbia’s rate would save about $1,040 a year on that basis. How your utility credits power you export decides how much bigger than your use a system should be, so read its rules first.
Test your roof with the solar potential tool, run quotes through the solar savings calculator, and read solar installation and how net metering works.
Batteries in Columbia
Here a battery is mostly about winter resilience: heat, light and a working fridge through an ice storm. Rural homes on co-op lines, with longer outages, gain the most. Ask your utility how it handles a battery connected with solar, since each one sets its own interconnection rules. See home battery installation and home battery cost.
EV charging in Columbia
Columbia has 63 public charging ports and Jefferson City 40 (AFDC data, October 3, 2026), with Interstate 70 running through Columbia. At home, about 30 kWh per 100 miles costs roughly $4.20 per 100 miles at Columbia Water & Light’s 2024 average and about $3.80 on Ameren (estimates). Try the EV charging cost calculator. A Level 2 charger needs a 240 V circuit from a licensed electrician and a permit; see EV charger installation. Ask your utility about any EV rate or rebate.

Permits and inspections
- Columbia: the city’s Building and Site Development division issues a specific residential solar photovoltaic permit. Ask the division which permits a generator, battery or EV circuit needs.
- Jefferson City: the Building Regulations Division handles building and electrical permits, including online applications, under the codes the city has adopted.
- Outside city limits: ask Boone or Cole County what it requires.
- Utility and HOA: your utility must approve the connection before you switch on. Subdivisions with an HOA usually need written approval.

Columbia energy FAQ
Who supplies electricity in Columbia, Missouri?
Most of the city is served by Columbia Water & Light, the city-owned utility. Boone Electric Cooperative and Ameren Missouri also serve parts of Boone County, including some areas near the city. Your bill shows which one you have, and that utility handles solar applications and approvals.
Who is the electric utility in Jefferson City?
Ameren Missouri serves Jefferson City, so Missouri’s statewide net metering rules apply there. Three Rivers Electric Cooperative and Co-Mo Electric Cooperative serve parts of Cole County outside the city. Building and electrical permits come from the city’s Building Regulations Division.
Do I need a permit for solar in Columbia?
Yes. Columbia’s Building and Site Development division issues a residential solar photovoltaic permit, and the city’s utility has its own interconnection application. Plan for both, and let your installer handle the paperwork if they are licensed for it.
Is backup power needed if Columbia’s outages are so short?
Day-to-day outages in the city are short, but ice storms and tornadoes are rated “relatively high” in Boone County by FEMA, and they can cut power for days. A small backup for heat, the fridge and medical devices is sensible; homes on rural co-op lines may want a generator.
