The Straight Answer: No, You Can't Choose Your Provider
No — you cannot choose your electricity provider in Missouri. This is a regulated electricity market: one utility holds the exclusive right to serve your address, and the Missouri Public Service Commission (PSC) approves what it can charge. Ameren Missouri serves the St. Louis metro and much of central Missouri; Evergy serves the Kansas City area; the rest of the state is covered by smaller investor-owned utilities, municipal utilities, or rural electric cooperatives. Whichever one covers your address, there's no second option next door and no supplier list to shop.
If that sounds like a gap compared to a state where you can pick a supplier, it isn't one in practice — deregulated markets swap "no choice" for "confusing choice," and the research on those markets (see our electrical guide for how wiring and panel issues play out state to state) shows most residential shoppers there don't come out ahead either. In a regulated state like Missouri, the honest homeowner question isn't "which supplier is cheapest" — it's "what actually lowers my usage and my bill." That's the rest of this page.
What Power Costs in Missouri
Missouri households paid an average of 13.5¢ per kilowatt-hour in 2025, per preliminary US Energy Information Administration data. The chart below shows the historical trend behind that number.

That 13.5¢ rate is up about 91 percent since 2005, and over the last decade the climb has held to roughly 1.9 percent a year. That's not a spike — it's a steady, compounding grind, the kind that turns a manageable bill into a much bigger one over ten or fifteen years if nothing on the usage side changes. The practical takeaway is to treat electricity like a cost that reliably gets a little more expensive every year, and to weight decisions — insulation, appliance replacement, solar — using that trajectory, not just this month's bill.
Why Your Rate Is Set This Way
Missouri's utilities are regulated monopolies: in exchange for the exclusive right to serve a territory, they submit to oversight from the Missouri Public Service Commission over what they can charge. Rates are set through a rate case, not a market — the utility files its costs and the PSC approves (or trims) what gets passed to customers, usually after a public comment period where residential and industrial customer groups can weigh in. That process is slower than a competitive market, but it's also the reason a Missouri bill doesn't move on a supplier's marketing budget or a teaser-rate expiration the way a bill in a deregulated state can.
A few cost drivers show up in Missouri rate cases more than most: the fuel mix (coal still supplies a large share of generation, alongside natural gas, nuclear at Ameren's Callaway plant, and a growing share of wind), ongoing grid modernization and transmission spending, and storm-hardening after the ice storms and severe thunderstorms that regularly hit the state. None of that is something a homeowner can negotiate around; it's baked into the approved rate everyone in a territory pays, whether you use a little power or a lot.
How to Actually Lower the Bill
With no supplier to shop, every dollar of savings in Missouri comes from usage or from generating your own power. That's actually a simpler set of choices than a deregulated state hands you — no offers to compare, no contract terms to track, no renewal date to calendar. In order of effort:
- Efficiency first. Attic and duct insulation, air sealing, and an HVAC tune-up or upgrade address the single biggest usage swing in most Missouri homes — humid summer air conditioning and cold winter heating both push bills hard. See our HVAC guide for what a tune-up should cover.
- Ask about time-of-use rates. Some Missouri utilities, including Ameren Missouri and Evergy, offer optional time-of-use pricing that charges less for power used off-peak. It's opt-in — you have to call and ask to be moved onto it — and it only pays off if you can shift some usage (laundry, EV charging, dishwashing) to off-peak hours.
- Ask about budget billing. Most Missouri utilities offer a levelized billing plan that averages your annual usage into a flat monthly payment, so a January heating spike or a July cooling spike doesn't hit as a shock. It doesn't lower the total you pay for the year, but it smooths the cash-flow problem that catches a lot of households off guard.
- Weigh rooftop solar against the 13.5¢ baseline. Solar economics are a direct function of your utility's rate — the higher the rate you're offsetting, the faster the payback. At 13.5¢ per kWh, Missouri sits close to the national average, so payback tends to run slower here than in higher-rate states. Whether it pencils out for your specific roof depends on your usage, your utility's net-metering terms, and the quote itself — run the numbers in our solar panels guide before signing anything.
Practical Checklist
- Confirm your utility — Ameren Missouri, Evergy, a municipal utility, or a rural co-op — from your bill, not a search result.
- Call and ask about time-of-use and budget billing. Neither is automatic; both require you to opt in.
- Schedule an HVAC tune-up before the next heating or cooling season, and check attic insulation depth.
- Get a solar quote only if your roof has strong, unobstructed sun exposure, and run the payback math against your actual usage and the 13.5¢ rate — not a salesperson's estimate.
- Ignore any unsolicited "switch providers" pitch. Missouri is regulated; there is nothing to switch.
