Missouri Electricity Rates: What to Know

Missourians have long paid some of the lowest electricity rates in the country, thanks to a fleet of cheap coal plants and abundant generation capacity. That reputation is starting to crack. Residential rates in Missouri now average about 13 to 14 cents per kilowatt-hour — still roughly 15 to 25 percent below the national average of 16.7 cents — but they are climbing fast. Rates jumped about 20 percent between 2020 and 2023, and 2025 brought even bigger increases: Evergy Missouri West raised rates 13.99 percent, Ameren Missouri added about 12 percent, and Liberty Utilities is phasing in another increase worth roughly $9 a month per year for typical customers.

The forces behind those increases are historic. Missouri is in the middle of an unprecedented data center boom — Ameren alone has signed construction agreements for more than 3 gigawatts of data center load, enough to nearly match the output of its largest coal plant. A new state law, SB 4, expanded how utilities can recover costs from ratepayers. And both Ameren and Evergy have pending rate cases and generation investments that will show up on bills for years to come. Understanding how Missouri's market works — and the concrete steps you can take to lower your bill — is the key to keeping costs in check.

How Missouri's Electricity Market Works

Missouri is a regulated electricity market. Unlike deregulated states where you can shop for an electricity provider, Missouri residential customers are served by whichever utility holds the franchise for their area. You do not get to choose, and there is no community choice aggregation program on the horizon.

The Missouri Public Service Commission (MPSC) regulates the state's investor-owned utilities: Ameren Missouri, Evergy Missouri Metro, Evergy Missouri West, and Liberty (the old Empire District Electric Company). The MPSC is a five-member body appointed by the governor and confirmed by the Missouri Senate. Its job is to balance the interests of ratepayers and shareholders — giving utilities an opportunity (but not a guarantee) to earn a reasonable return on investment while keeping service safe, reliable, and reasonably priced.

The MPSC does not regulate municipal utilities like Columbia Water & Light, Springfield City Utilities, and Independence Power & Light. It also does not regulate the roughly 47 rural electric cooperatives that serve much of rural Missouri. Those utilities are self-governing, set their own rates, and answer to their own boards or city councils rather than state regulators.

Here is a quick breakdown of Missouri's utility landscape:

Utility Type	Regulation	Examples
Investor-Owned Utilities (IOUs)	MPSC-regulated	Ameren Missouri, Evergy Missouri Metro, Evergy Missouri West, Liberty
Municipal Utilities	City-governed	Columbia Water & Light, Springfield CU, Independence P&L
Rural Electric Cooperatives	Member-governed	~47 co-ops, most wholesale from AECI

Because you cannot shop for a different provider, your main levers for controlling costs are managing your usage, choosing the right rate plan, taking advantage of assistance programs, and investing in efficiency or solar where it makes sense.

What Missourians Actually Pay

Let us put real numbers on the table. The average residential electricity rate in Missouri as of early 2026 ranges from about 13.37 cents per kWh (PriceOfElectricity.com, February 2026) to roughly 14 cents per kWh (EnergySage, March 2026). For comparison, the national average sits around 16.7 cents per kWh, which means Missouri customers pay roughly 15 to 25 percent less per unit of electricity than the typical American household.

The average monthly residential bill is harder to pin down because different sources measure it differently. One widely cited estimate puts the typical Missouri household bill at about $137 per month, compared with a national average near $147. EnergySage, which collects bills directly from solar shoppers, reports an average closer to $189 — but those figures skew toward larger homes with higher usage. Whichever number you trust, the bill is going up.

The trend matters more than the snapshot. Missouri rates jumped about 20 percent from 2020 to 2023 — an extra $327 per year for the average household — and in 2023 the state ranked fourth in the nation for the biggest jump in electricity prices. The 2025 rate cases kept that momentum going:

Utility	Rate Change	Effective	Typical Impact
Evergy Missouri West	+13.99%	Jan 1, 2025	~$27/month on a $200 bill
Ameren Missouri	~+12% (settled)	June 1, 2025	~$14/month
Liberty (Empire District)	~$97M increase	Jan 2026	~$9/month per year (phased)
Evergy Missouri Metro	+14.9% (requested)	Jan 2027 (pending)	~$17.70/month if approved

Stacked together, those increases are adding real money to Missouri bills. If your bill has been climbing and you want to figure out exactly where the money is going, our guide on how to read your electric bill and spot overcharges walks through every line item on a typical Missouri utility statement.

Major Utilities Serving Missouri

Four investor-owned utilities cover most of Missouri's population. Here is how they compare.

Ameren Missouri

Ameren Missouri (formally Union Electric Company, a subsidiary of Ameren Corporation) is the largest electric utility in the state. It serves 1.2 million electric customers and 132,000 natural gas customers across 64 counties and more than 500 communities in central and eastern Missouri, including the greater St. Louis area.

Ameren filed a rate case in July 2024 asking the MPSC for a 15.49 percent increase — about $446 million annually, or about $17.45 more per month for a typical residential customer. After months of hearings and negotiations, the MPSC approved a settlement in April 2025 for roughly $355 million, an increase of about 12 percent for residential customers. That translates to about $14 more per month. One concession held the fixed residential customer charge at $9 per month rather than letting Ameren raise it to $10.43, and another blocked Ameren from passing through certain costs from the Rush Island coal plant Clean Air Act case.

Ameren's Rush Island Energy Center — a 1,178 megawatt coal plant on the Mississippi River in Jefferson County — shut down in 2024 after more than 13 years of federal litigation. A court ruled that Ameren had made modifications to the plant's boilers without required permits, resulting in excess SO2 emissions. Rather than install costly pollution controls, Ameren opted to retire the plant early. The MPSC later approved securitization of roughly $461 million in stranded costs, meaning ratepayers are on the hook for the write-down.

Looking ahead, Ameren's integrated resource plan calls for adding 2,800 megawatts of wind and solar, 400 megawatts of battery storage, and an 800 megawatt natural gas plant by 2030. The company has committed to net-zero carbon emissions by 2050. Additional units at the Labadie Energy Center are scheduled to retire in phases through 2042.

Evergy Missouri (Metro and West)

Evergy was formed by the 2018 merger of Westar Energy and Kansas City Power & Light. Its Missouri operations are split into two service areas — Evergy Missouri Metro covering the Kansas City metropolitan area plus Higginsville and Marshall, and Evergy Missouri West serving western Missouri outside the KC metro. Together, Evergy serves about 640,000 power customers across Missouri.

Evergy Missouri West raised rates 13.99 percent on January 1, 2025, after MPSC approval in December 2024. For a customer with a $200 monthly bill, that is an extra $27 per month — about $324 per year. Evergy cited cost recovery for two new natural gas plants and grid upgrades in its filing.

Evergy Missouri Metro had not filed a general rate review since February 2022, but state law requires one every four years. In February 2026 Evergy asked the MPSC for a 14.9 percent increase — about $137.9 million annually — citing $500 million in grid infrastructure investments since the last review. If approved, new rates would take effect in January 2027 and add about $17.70 per month for a typical residential customer. Evergy has publicly stated that no data center costs are included in this request, though critics remain skeptical.

Evergy is also reshaping its generation fleet. In 2025 the company updated plans to retire and convert units at the Jeffrey Energy Center and Lawrence Energy Center, though critics including the Sierra Club have pointed out that these retirements have been repeatedly delayed. Evergy plans to continue operating part of its Iatan power plant past 2040.

Liberty (Empire District)

Liberty — known to longtime customers as Empire District Electric — is owned by Algonquin Power & Utilities and serves about 164,000 electric customers in Missouri, mostly in the Joplin area and surrounding southwest Missouri counties. The company also serves customers in Kansas, Oklahoma, and Arkansas, with a combined territorial total of about 215,000.

Liberty filed a 2025 rate case requesting an eye-popping 29.64 percent increase — roughly $152 million in additional annual revenue. After months of hearings and fierce pushback from customers and consumer advocates, the MPSC approved a conditional rate increase in January 2026 for up to $97 million. For a typical customer using 1,000 kWh per month, that translates to about $9 extra per month per year, phased in over two years. The rate increase was approved conditionally because of ongoing customer service concerns at Liberty.

Liberty has a complicated history with Missouri's renewable energy standard. After a five-year legal battle, the Missouri Supreme Court ruled that Empire District had to comply with the solar rebate requirements of Proposition C — a rare judicial slap-down of a utility's refusal to implement voter-approved policy.

Municipal Utilities and Cooperatives

If you live in Columbia, Springfield, or Independence, your power likely comes from a city-owned municipal utility. These utilities are governed by elected city councils or appointed boards rather than the MPSC. In much of rural Missouri, power comes from one of the roughly 47 rural electric cooperatives, most of which buy wholesale power from Associated Electric Cooperative, Inc. (AECI).

Municipal and cooperative customers generally pay less than IOU customers on a per-kWh basis because these utilities are nonprofit. But they also have their own rules for net metering, assistance programs, and rate changes — so check with your specific provider rather than assuming IOU rules apply.

Why Missouri Electricity Rates Are Rising

Missouri has been cheap for decades. Why the sudden surge? Several forces are colliding at the same time.

The Data Center Boom

This is the dominant story. Ameren Missouri has executed construction agreements for more than 3 gigawatts of data center load as of early 2026 — enough to nearly match the entire capacity of the Labadie coal plant, Ameren's largest facility. 48 data centers are already operating in Missouri, including hyperscale facilities from Meta, Google, and Amazon, and another 36 are planned or under construction.

That new load has to come from somewhere. Infrastructure costs for a single large data center customer can exceed $1 billion. Data center developers have already paid Ameren about $46 million in nonrefundable payments to cover the cost of transmission upgrades, but consumer advocates worry that residential ratepayers will end up covering the rest through higher rates and bigger generation investments.

In November 2025 the MPSC approved new consumer-protection tariffs designed to insulate residential customers from data center costs. Ameren's new tariff applies to customers using 75 megawatts or more — more than double the usage of Ameren's largest customer in 2024. The key provisions include:

• 12-year minimum service term
• Two-year notice required to terminate or reduce contracted load
• Early exit fees to discourage data centers from walking away
• Excess profit sharing: if Ameren's return on equity from these customers exceeds 9.74 percent, 65 percent of excess profits must be returned to other customers, with 15 percent earmarked specifically for low-income households
• Similar rules for Evergy were approved the same month

Sierra Club, Renew Missouri, Google, Amazon, and MPSC staff all supported the Ameren tariff. But the Consumers Council of Missouri asked for a redo in December 2025, arguing residential customers remain exposed to infrastructure risk. Expect this fight to continue as more data centers come online.

SB 4 and Expanded Cost Recovery

Governor Mike Kehoe signed Senate Bill 4 into law on April 9, 2025, and it took effect August 28, 2025. The law made several structural changes that consumer advocates warn will raise rates for years:

• Expanded Plant in Service Accounting (PISA) — utilities can now recover depreciation on new natural gas plants over 20 years rather than waiting for a full rate case
• Future test year rates — allows utilities to set rates based on projected (rather than historical) costs
• Overturned the Construction Work in Progress statute — a longstanding rule that had limited how utilities could charge customers for unfinished projects

The Consumers Council of Missouri projects that SB 4 could add an average of more than $1,000 per year to household bills over the next decade. The law was pitched as necessary to attract new generation capacity and support economic growth, but critics argue it fundamentally shifts risk from shareholders to ratepayers.

Coal Retirements and Generation Investments

Ameren's Rush Island shutdown alone created roughly $461 million in securitized stranded costs that customers must pay off. Future unit retirements at Labadie through 2042 will generate more. Both Ameren and Evergy are investing heavily in new generation — wind, solar, battery storage, and new natural gas peaker plants — to replace retiring coal capacity and meet new load. All of that capital investment flows into the rate base.

Grid Modernization

Both major IOUs cite storm hardening, substation upgrades, cable replacement, and smart grid deployment as rate drivers. Missouri's severe weather — ice storms, tornadoes, straight-line winds — makes grid reliability a real concern, and the bills for that work are landing now.

Bottom Line

Missouri's utility rates are rising from a low base toward the national average. The cumulative effect of data center growth, SB 4, coal retirements, and ongoing rate cases is significant. Customers who assume Missouri will always be "cheap" and do nothing to manage usage are likely to see their bills climb sharply through the rest of the decade.

Understanding Missouri's Rate Structures

Knowing how your rate actually works can help you save real money. Missouri IOUs use a combination of fixed charges and variable energy charges, and most offer optional time-of-use plans that can meaningfully lower your average rate.

Fixed Customer Charges and Seasonal Pricing

Every Missouri IOU bill includes a fixed monthly customer charge (about $9 per month for Ameren residential customers after the 2025 settlement). This charge applies regardless of how much electricity you use. Then comes the energy charge — the cents-per-kWh figure that scales with your consumption.

Missouri utilities also use seasonal pricing. Summer rates (June through September for Ameren) are typically higher than winter rates (October through May) because of higher demand and peak loads from air conditioning. If you run a window AC unit hard in July, you will feel those summer rates.

Ameren Missouri Time-of-Use Options

Ameren offers five different rate plans for residential customers with smart meters. Choosing the right one can cut your bill significantly:

1. Anytime Users — flat rate, no time-of-use. The default if you do nothing.
2. Evening/Morning Savers — discounted rate for energy used during off-peak evening and morning hours.
3. Overnight Savers — discounted rate for energy used between 10 PM and 6 AM. Excellent for EV owners who can charge overnight.
4. Smart Savers — advanced off-peak/on-peak rate with mid-peak pricing.
5. Ultimate Savers — off-peak/on-peak rate plus a demand charge. Complex, but can pay off for high users who can shift large loads.

Ameren's on-peak hours run 6 AM to 10 PM, seven days a week, with off-peak from 10 PM to 6 AM. That is a relatively long on-peak window — so the biggest savings come from shifting things like EV charging, clothes drying, and dishwasher cycles overnight.

Evergy Time-of-Use Options

Evergy shifted to default time-of-use pricing in 2023. Missouri customers can choose from four plans:

1. Default Time Based Plan — peak pricing 4-8 PM on weekdays
2. Summer Peak Time Based Plan — only summer has peak pricing
3. Nights & Weekends Plan — cheaper rates nights and weekends
4. Nights & Weekends Max Plan — even steeper off-peak discounts

Evergy's default peak hours — 4 to 8 PM on weekdays — are much shorter than Ameren's, which makes it easier to avoid peak pricing. Anyone who can run the dishwasher after 8 PM or schedule EV charging overnight can see real savings. Evergy offers a Rate Comparison Tool on its website that models what each plan would cost based on your actual usage history.

What Is on Your Bill

A typical Missouri electricity bill includes several components beyond the basic energy charge:

• Fixed customer charge — flat monthly fee
• Energy charge — variable, based on kWh used (sometimes tiered or time-of-use)
• Fuel adjustment clause — passes through the utility's fuel and purchased power costs
• Environmental cost recovery — covers environmental compliance investments
• Franchise and municipal taxes
• Missouri state sales tax on electricity

Missouri is one of the few states that still applies sales tax to residential electricity, which adds a few percent to every bill. If your bill looks higher than you expect and you are not sure why, our bill reading guide walks through the math.

Solar Energy in Missouri

Missouri sits in a decent solar belt — better than people expect, with strong summer sun and reasonable winter production. With rates climbing and data center demand reshaping the grid, solar is worth a serious look for Missouri homeowners who can afford the upfront cost.

Net Metering

Missouri's Easy Connection Act (RSMo §386.890), passed in 2007, requires all utilities — IOUs, municipal utilities, and cooperatives — to offer net metering for systems up to 100 kilowatts. For residential customers of Ameren, Evergy, and Liberty, excess generation is credited at the full retail rate, which is the most favorable arrangement possible. Credits roll over monthly and expire after 12 months if unused.

There are a few important caveats:

• The 100 kW system cap is smaller than in many states (some allow up to 1 MW for residential and small commercial)
• Rural electric cooperatives credit excess generation at the much lower "avoided cost" rate set by wholesale supplier AECI, not the retail rate. If you are a co-op customer, this dramatically changes the economics of solar.
• Simple one-page application for systems 10 kW or less

For homeowners on Ameren or Evergy, the retail-credit structure makes rooftop solar economically viable despite the recent loss of the federal tax credit.

What Solar Costs in Missouri

The average installed cost of residential solar in Missouri as of April 2026 runs about $2.54 to $2.80 per watt. A typical 9 kW system costs around $28,500 gross, before any tax exemptions. Missouri does offer a 100 percent property tax exemption on solar-added home value and a full sales tax exemption on solar equipment purchases — together worth about $850 to $1,100 for most installations.

Payback periods depend on your utility, usage, and system size, but most Missouri homeowners see paybacks in the 10 to 15 year range now that the federal tax credit has expired. Before the credit lapsed, paybacks were closer to 6 to 10 years.

The Federal Tax Credit Loss

Big change for 2026: the 30 percent residential federal solar tax credit (Section 25D) was repealed as part of the One Big Beautiful Bill Act signed July 4, 2025. Homeowners had to have purchased and incurred qualifying expenses by December 31, 2025 to claim the credit. That is a serious headwind for Missouri solar economics.

Some options remain:

• Third-party ownership (leases and PPAs) can still benefit from the commercial investment tax credit through 2027 — worth considering if the upfront cost of buying a system is out of reach
• Missouri's sales tax and property tax exemptions still apply
• Rising electricity rates shorten payback periods over time — every rate increase adds to the value of the electricity your panels produce

Ameren and Evergy Solar Rebates

Proposition C, passed by Missouri voters in 2008, originally required investor-owned utilities to offer $2 per watt solar rebates covering 25 to 50 percent of system cost. Those rebate programs were funded through 2023 and have largely ended. Ameren Missouri's solar rebate closed December 31, 2023, and most Evergy and Liberty rebate programs are similarly paused or closed to new applications.

That said, Missouri still has one of the more favorable net-metering structures in the Midwest for IOU customers, and the long-term economics of solar in the state remain reasonable — especially as rates continue to climb. For advice on picking the right system, see our guide on choosing the best solar panels for your home. If rooftop solar is not right for you — maybe because you rent, have a shaded roof, or live in a co-op territory with unfavorable credit — community solar can be an alternative, though Missouri's community solar market is smaller than those in Illinois or Minnesota.

Strategies to Lower Your Missouri Electricity Bill

Every dollar you save on your electricity bill today is worth more tomorrow because rates are climbing. Here are the highest-impact moves for Missouri homeowners.

1. Switch to a Time-of-Use Rate Plan

Both Ameren and Evergy offer optional TOU plans that can cut your bill significantly if you can shift heavy loads to off-peak hours. For Evergy customers, avoiding the 4-8 PM peak window on weekdays is the easiest win. For Ameren customers, overnight use (10 PM to 6 AM) unlocks the biggest discounts — particularly valuable for EV owners. Use Evergy's Rate Comparison Tool or Ameren's rate calculator to see which plan fits your household's usage pattern before switching.

2. Apply for Dollar More and LIHEAP Even If You Think You Do Not Qualify

Ameren Missouri's Dollar More program now accepts applications from households at up to 300 percent of the federal poverty level — a very generous threshold. Combined with LIHEAP, qualifying households can receive up to $1,400 per year in bill assistance. Do not assume you earn too much to qualify. Call 1-800-552-7583 or visit dollarmore.ameren.com to check.

3. Improve Your Home's Envelope

Missouri has hot, humid summers and cold winters, so heating and cooling dominate most electric bills. Insulation, air sealing, and duct sealing pay back quickly. A smart thermostat can save another 8 to 15 percent on heating and cooling costs by automatically adjusting temperatures when you are asleep or away.

4. Consider a Heat Pump

Modern cold-climate heat pumps work down to well below zero and can cut heating costs significantly compared with electric resistance or propane heat. Even gas furnace users often find that pairing a heat pump with existing gas heat saves money. See our guide on the best heat pumps for home in 2026 for the latest models and rebates.

5. Monitor Your Usage

You cannot manage what you do not measure. A home energy monitor shows you exactly where your electricity is going — often revealing surprises like an old freezer running inefficiently, a phantom load from entertainment equipment, or HVAC cycling more than it should. Targeting wasted kWh is often cheaper than any rate plan change.

6. Electrify Strategically

If you are planning renovations or appliance replacements, consider whether electrification makes sense. Our whole-home electrification guide walks through the steps. Electric heat pumps, heat pump water heaters, and induction cooking can reduce overall energy costs when combined with good insulation and weatherization — especially if Missouri electricity rates rise more slowly than natural gas prices.

7. Go Solar if You Are a Good Candidate

Despite the federal ITC expiring, solar still works for many Missouri homeowners — especially IOU customers with unshaded south-facing roofs, high usage, and a long-term perspective on rising rates. If you are going to live in your home for 15+ years, run the numbers. Get multiple quotes, watch for slick sales pitches, and make sure your installer understands Missouri's net metering rules for your specific utility.

8. Cut Your Largest Loads

Air conditioning, water heating, laundry, and EV charging tend to dominate residential electricity bills. Our guide on how to cut your electric bill in half covers the highest-impact moves for each category.

Low-Income Assistance Programs

Missouri has multiple programs to help struggling households keep the lights on. If you are behind on your bill or worried about disconnection, these are real safety nets — and eligibility criteria are more generous than most people realize.

LIHEAP and Energy Crisis Intervention Program (ECIP)

The Low Income Home Energy Assistance Program (LIHEAP) is the federal bill payment program administered in Missouri by the Department of Social Services. It has two components:

• Energy Assistance (EA) — one-time heating payment available October through May
• Energy Crisis Intervention Program (ECIP) — emergency assistance for households facing disconnection, final termination notice, or out of fuel

For the 2025-2026 winter season, the maximum Winter Crisis benefit is $800 and the Summer Crisis benefit is $300. Eligibility is based on household income at or below 60 percent of State Median Income. Elderly or disabled households could apply starting November 1, 2025; all other households from December 1, 2025, through May 31, 2026. Apply through your local Community Action Agency.

Federal LIHEAP funding was delayed in late 2025 after a federal government shutdown, but Missouri applications remained open through contracted agencies.

Dollar More (Ameren Missouri)

Dollar More is funded by voluntary customer and company donations at Ameren Missouri. Eligibility was recently expanded to 300 percent of the federal poverty level — meaning a family of four earning up to roughly $98,000 per year could qualify. Benefits provide up to $600 per year in bill assistance.

For the 2025-2026 program year, Ameren had more than $1.5 million in Dollar More funds available. Applications are accepted through May 31, 2026. Call 1-800-552-7583 or visit dollarmore.ameren.com. Ameren partners with local Community Action agencies, which can also help you apply for LIHEAP and weatherization programs simultaneously. Stacking Dollar More and LIHEAP gets qualifying households up to about $1,400 in combined assistance.

The Cold Weather Rule

Missouri's Cold Weather Rule protects MPSC-regulated gas and electric customers from disconnection during the winter months. The rule runs November 1 through March 31 each year, and it was significantly expanded in 2025. Under the new rules:

• Utilities cannot disconnect heat-related service when the National Weather Service forecasts temperatures below 32°F within the next 72 hours (up from 24 hours previously)
• Customers can enter into a 12-month payment agreement to keep service on
• Initial payment is no more than 12 percent of the 12-month agreement
• Low-income elderly or disabled customers who register with their utility can temporarily reduce monthly payments to 50 percent of the current bill during the Cold Weather Rule period (the other 50 percent is due after the period ends)

The Cold Weather Rule applies to IOUs (Ameren, Evergy, Liberty) but not to municipal utilities or rural electric cooperatives. If you are a municipal or co-op customer, contact your utility directly to ask about their disconnection policies — most have their own programs, but they are not bound by the MPSC rule.

If you need help navigating any of this, call the MPSC hotline at 1-800-392-4211 or dial 211 to connect with local assistance agencies. Do not wait until disconnection is imminent.

Frequently Asked Questions

What is the average electricity rate in Missouri?

As of early 2026, the average residential electricity rate in Missouri is approximately 13 to 14 cents per kWh. This is roughly 15 to 25 percent below the national average of about 16.7 cents per kWh. Missouri has historically enjoyed cheap power thanks to an abundance of coal generation, but rates are rising quickly. The cumulative increase from 2020 to 2023 alone was about 20 percent, and major rate cases in 2025 and 2026 are pushing bills higher still.

Why is my Missouri electricity bill going up so fast?

Several forces are driving rate increases: (1) an unprecedented data center boom, with Ameren alone signing construction agreements for more than 3 GW of new load from Meta, Google, Amazon, and others; (2) SB 4, a 2025 state law that expanded how utilities can recover costs from ratepayers; (3) coal plant retirements like Ameren's Rush Island facility, which left roughly $461 million in stranded costs for customers to pay off; (4) new generation investments including wind, solar, battery storage, and natural gas; and (5) grid modernization and storm hardening.

Can I choose my electricity provider in Missouri?

No. Missouri is a regulated electricity market. You are served by whichever utility holds the franchise for your address — typically Ameren Missouri, Evergy Missouri Metro, Evergy Missouri West, Liberty, a municipal utility, or a rural electric cooperative. Missouri does not have retail choice or community choice aggregation for residential customers. Your levers for cost control are managing usage, choosing the right rate plan, and taking advantage of assistance programs.

Does Missouri have net metering?

Yes. Missouri's Easy Connection Act (RSMo §386.890) requires all utilities to offer net metering for systems up to 100 kilowatts. Investor-owned utilities (Ameren, Evergy, Liberty) must credit excess generation at the full retail rate, which makes solar economically viable. Rural electric cooperatives, however, credit excess generation at the much lower "avoided cost" rate set by wholesale supplier AECI — which significantly changes the economics. If you are a co-op customer, check your specific cooperative's policies before investing in solar.

Is solar still worth it in Missouri in 2026?

It is more challenging than it used to be. The 30 percent federal residential solar tax credit (Section 25D) expired December 31, 2025, which adds roughly $8,000 to the cost of a typical system. Payback periods have lengthened from 6-10 years to 10-15 years for most Missouri homeowners. But solar still makes sense for many — especially IOU customers with high usage, unshaded roofs, and a long-term horizon. Missouri's property tax exemption, sales tax exemption, and retail-credit net metering (for IOU customers) still apply, and rising rates continue to improve the math every year.

What is the Cold Weather Rule and how does it protect me?

Missouri's Cold Weather Rule prohibits MPSC-regulated utilities from disconnecting heat-related service when temperatures are forecast to drop below 32°F within the next 72 hours (expanded from 24 hours in 2025). The rule runs November 1 through March 31. Customers can enter into a 12-month payment agreement to keep service on, and low-income elderly or disabled customers can temporarily cut their monthly payment in half during winter. The rule does not apply to municipal utilities or rural electric cooperatives — check with your specific provider if that is you.

What happens if I cannot pay my electricity bill?

Missouri has several safety nets. LIHEAP provides up to $800 in Winter Crisis benefits through the Department of Social Services. Dollar More from Ameren Missouri offers up to $600 per year in bill assistance with income eligibility up to 300 percent of the federal poverty level. The Cold Weather Rule provides protection during winter months. Call the MPSC at 1-800-392-4211 or dial 211 to connect with local assistance agencies. Do not wait until you receive a disconnection notice — the earlier you reach out, the more options are available.

How do Missouri data centers affect my bill?

This is the biggest open question. Hyperscale facilities from Meta, Google, Amazon, and others are consuming enormous amounts of power — Ameren has signed agreements for more than 3 GW of data center load. To prevent residential customers from subsidizing that growth, the MPSC approved new data center tariffs in November 2025 that require 12-year minimum contracts, exit fees, two-year termination notice, and excess profit sharing. If Ameren's return on equity from large customers exceeds 9.74 percent, 65 percent of excess profits must be returned to other customers, with 15 percent earmarked for low-income households. Consumer advocates argue these protections are not strong enough, and the fight is ongoing.

Will Missouri electricity rates keep going up?

Almost certainly, at least for the next several years. Pending rate cases (Evergy Missouri Metro's 14.9 percent request for 2027), ongoing generation investments, continued data center load growth, SB 4's expanded cost recovery mechanisms, and coal retirement costs all point to higher bills. The Consumers Council of Missouri estimates SB 4 alone could add more than $1,000 per year to the average household over the next decade. Planning for continued rate increases is a safer assumption than hoping for a reversal.

Your Missouri Electricity Action Plan

Here is a concrete plan to take control of your electricity costs.

This week:

1. Pull up your most recent utility bill and identify your current rate plan, monthly kWh usage, and all the line items. If anything looks unfamiliar, our bill reading guide will help you decode it.
2. Log into your utility's website (amerenmissouri.com, evergy.com, or libertyutilities.com) and review your usage history for the past 12 months. Note your seasonal highs and lows.
3. Check whether a time-of-use rate plan would save you money. Ameren's Overnight Savers plan is ideal for EV owners and households that can shift usage to 10 PM-6 AM. Evergy's Nights & Weekends plans favor households that use most power in the evening and on weekends.

4. Call Ameren Missouri's Dollar More line (1-800-552-7583) to check if you qualify for bill assistance — the 300 percent federal poverty level eligibility covers a lot more households than people realize.
5. Apply for LIHEAP through your local Community Action Agency if your income is at or below 60 percent of State Median Income.
6. Evaluate insulation, air sealing, and HVAC efficiency. A simple home energy audit can identify low-hanging fruit. Consider a smart thermostat for automatic savings on heating and cooling.
7. Install a home energy monitor so you can spot wasted kWh and track the impact of the changes you make.

If you are struggling to pay your bill:

8. Contact your utility immediately — do not wait until you get a disconnection notice. Ask about payment agreements and the Cold Weather Rule (if in season).
9. Call 1-800-392-4211 for the Missouri PSC hotline or dial 211 to connect with local assistance.
10. Check the Dollar More and LIHEAP eligibility criteria. You may qualify for more than you expect.

For the long term:

11. Budget for continued rate increases. Missouri has been cheap for a long time, but SB 4, data center growth, and pending rate cases all point to higher bills through the rest of the decade.
12. If you are considering solar, get multiple quotes from Missouri installers who understand your specific utility's net metering policies. Remember: IOU customers get retail credit, co-op customers do not.
13. Plan major appliance replacements with efficiency in mind. A heat pump, heat pump water heater, or whole-home electrification strategy can lock in long-term savings.

Missouri's electricity landscape is changing fast. For decades the state was a reliably cheap place to keep the lights on, built on coal and stable regulation. That era is ending — not because Missouri is becoming expensive, but because data center demand, SB 4, and coal retirements are closing the gap with the national average. The Missourians who pay the least over the next decade are the ones who understand their utility, pick the right rate plan, use every assistance program they qualify for, and invest in the efficiency upgrades that pay back fast. The tools are there. You just have to use them.
