Residents in Missouri who request quotes on the EnergySage Marketplace spend an average of $197 monthly on electricity. That adds up to $2,364 per year. A different way to look at it is that a typical Missouri resident uses 1,387 kWh of electricity per month and 16,646 kWh over the year.
(For what it’s worth: Missouri residents shopping for solar on EnergySage may use more electricity than a typical household.)
The easiest way to compare electricity costs across regions is to look at the electricity rate. In the U.S., residential rates generally range from 11 ¢/kWh all the way up to 34 ¢/kWh.
As of February 2026, the cost of electricity in Missouri is 14 ¢/kilowatt-hour (kWh)—roughly 29% lower than the national average cost. That number is based on real-world electric bills shared with EnergySage over the past 12 months. You can compare that number to the most recent average state electric price reported by the U.S. Energy Information Administration (EIA).
Missouri’s electricity market is regulated, so you can’t choose which company supplies your electricity. Instead, the state determines your electric utility company based on where you live. There are three primary electricity companies in Missouri, all of which are Investor Owned Utilities (IOUs), meaning they're private for-profit companies:
Ameren Missouri
Evergy
Liberty Utilities
While the IOUs cover much of the state, some towns and cities are served by municipally-owned, not-for-profit electric companies that aren't subject to the same requirements as IOUs. These municipal utilities may offer lower rates, but may not offer benefits like net metering.

When you pay your electric bill, you’re not only covering the costs to produce that electricity, but also the costs of running and maintaining the electrical grid, as well as public benefit funds that promote things like renewable energy and energy efficiency.
Electric bill costs are rolled into fixed (monthly customer charges) and variable charges (¢/kWh that you use).
Fixed charges, like the flat fee for having a meter, generally remain the same monthly unless your utility makes a policy update.
Your variable charges will change every month and depend on your electricity rate and how much electricity you use.
Your electric bill's variable charges will include a supply (or generation) charge and a transmission and distribution (or delivery) charge. The supply charge covers the cost of electricity generation, while the transmission and distribution charges cover the cost of delivering it to your home.
Depending on your utility company in Missouri, you may have the option to sign up for variable-rate plans, like time-of-use (TOU) rates or demand charge plans, which can help you save even more on your monthly electric bill if used in tandem with a solar or solar-plus-storage system.
How clean is the electricity in Missouri?
Due to the complex nature of utility grids, it's not easy to pin down exact data regarding exactly where the energy that goes to your specific home comes from, but according to the U.S. Energy Information Administration, about 78% of the electricity on Missouri’s utility grid comes from fossil fuels—primarily coal—as of August 2025.
Only about 9% comes from renewable sources. Given that more than three-fourths of the grid’s energy comes from fossil fuels, installing a home solar panel system in Missouri will almost always shrink your carbon footprint.
Some electricity suppliers give you the option to pay a bit more so that most (or even all) of your electricity comes from renewable sources. If you’re unwilling or unable to go solar in Missouri but still want to reduce your carbon footprint, this is a great alternative. It just won’t save you any money in most cases. (Though occasionally it could if it’s through a municipal group-buy program).
As long as you have a suitable roof, one of the surest ways to save on energy is to go solar—ideally with a vetted contractor offering a competitive price.
Solar panels will reduce or even eliminate your electric bills in the short term and protect you against rising electricity costs in the long run, too. The amount you save depends on how much you spend on electricity now and how much of your electric bill you can offset with solar energy.
Solar panels are a big investment, but Missouri homeowners who install them—and pay upfront—break even after an average of just 11.68 years. Then, the solar panels will continue to produce free electricity for years to come.
Does Missouri offer net metering?
On sunny days, you can usually count on your solar panels to generate more than enough energy to meet your home’s needs.
That extra energy doesn’t go to waste. In Missouri, all utility companies are required to offer net metering, a solar buyback program that provides energy credits for all the solar power you send to the grid. Later, when you need to pull electricity from the grid (like at night or on cloud days), your utility company deducts from your banked energy credits instead of charging you.
Under net metering, it doesn’t matter when you produce solar power—it just depends how much you produce in total throughout the year. At the end of the month, you’ll only be billed for the electricity you pulled from the grid.
While net metering is widely available in Missouri, rates vary depending on your specific utility company. No matter which utility company you use, though, credits work on a use-them-or-lose-them basis; you can roll them over month to month, but they expire after 12 months.
How much can you save with solar?
Electricity prices are on the rise in Missouri, which means you can save big when you go solar in Missouri.
Just take a look at how much you'll spend on electricity over time based on your current bill. It’s easy to see how going solar can pay off quickly.
Electricity cost over time in Missouri
Current monthly electric bill | 10-year electricity cost | 20-year electricity cost | 30-year electricity cost |
|---|---|---|---|
$50 | $6,600 | $15,000 | $24,000 |
$100 | $13,000 | $29,000 | $49,000 |
$150 | $20,000 | $44,000 | $73,000 |
$200 | $26,000 | $58,000 | $97,000 |
$250 | $33,000 | $73,000 | $120,000 |
Assuming a 2% annual increase based on inflation and average annual electric rate increases in Missouri.
Let's assume you pay $197 for electricity monthly (the Missouri average) and that electricity prices increase by 2% annually. Let's also assume you buy your solar panel system upfront and that it costs you $33,000 before any available incentives.
In the first year with solar, you'll avoid spending $2,400 on electric bills. Over five years, you'll avoid $12,300; by 10 years, you'll have avoided $25,800. Solar panels are usually covered under warranty for 25 years—by then, you'll have avoided spending $75,600 on electric bills in Missouri.
The average payback period in Missouri is 11.68 years, so by this point, you've already broken even on your investment. When you subtract your upfront installation cost, you'll pocket $42,300 over 25 years with solar.
Your solar savings depend on you
How much your utility company charges for electricity is a big indicator of how much you'll save with solar. But your exact solar savings depend on your unique situation—including your energy usage, roof layout, system size, and how you pay for your system.
Here are some reasons your savings could be below average:
You don’t use much electricity, or your roof is small or has a less-than-ideal layout. You might have a relatively long payback period, so you'll save a little less over time.
You don't install enough solar panels to 100% offset your energy use. You’ll pay less up front but save less in the long run.
You finance your solar panel system with a loan or sign a lease or power purchase agreement (PPA) instead of paying up front. These types of arrangements can make a lot of sense for keeping your capital flexible and will allow you to start saving sooner. But they will cut into your long-term savings.
Choosing a high-quality solar installer is the key to getting a top-notch solar panel system that will help you save on electric bills.
