EV Charging in Missouri

Missouri's investor-owned utilities offer residential time-of-use options suitable for EV charging. Ameren Missouri's Evening/Morning Savers and Overnight Savers rates discount off-peak overnight hours, Evergy Missouri West offers an optional time-of-use plan with lower overnight pricing, and Liberty Utilities (Empire District) in southwest Missouri publishes its own residential rate options. Specific window times and price differentials vary by plan; confirm current details on the utility tariff pages before enrolling.

Missouri's Net Metering and Easy Connection Act (RSMo 386.890) provides netting within a billing period at the retail rate for residential systems up to 100 kW. Net excess generation at the end of the billing period is credited at the utility's avoided-cost rate, well below retail, and unused credits expire on the annual true-up. Ameren Missouri and Evergy Missouri each administer this through their respective net metering riders under MO PSC oversight.

Missouri has no right-to-charge statute. HOAs and condominium associations may lawfully restrict or prohibit EV charging station installation, subject only to general architectural-review obligations under the governing documents.

Missouri assesses an annual Alternative Fuel Vehicle decal fee under Mo. Rev. Stat. § 142.869 in lieu of motor fuel tax, with amounts that scale by gross vehicle weight rating. Recorded amounts reflect the 2026 fee for passenger BEVs at or below 18,000 lbs GVWR; PHEVs pay half the BEV rate. Heavier vehicles (commercial, school bus classes) pay higher decal amounts on the same statutory schedule.
