Yearly figures are the average of the monthly EIA residential rates for that year. A year that is incomplete is labelled with the months it covers, and its change is measured against the same months of the previous year — residential rates are seasonal, so comparing a part-year against a full year would measure the season rather than the trend. Every row carries its own change, including the oldest one shown: its comparison year is the year immediately before the table starts. Where a comparison period is missing entirely, the change columns are left blank rather than filled with a zero.
Why did electricity prices rise in Missouri?
What the EIA series shows
- Past 12 months (May 2025 → May 2026)
- The Missouri residential rate rose 5.1% (+0.67¢/kWh), from 13.01¢ in May 2025 to 13.68¢ in May 2026.
- Past 5 years (May 2021 → May 2026)
- The rate rose 20.2% (+2.30¢/kWh), from 11.38¢ in May 2021 to 13.68¢ in May 2026.
- Past 10 years (May 2016 → May 2026)
- The rate rose 11.8% (+1.44¢/kWh), from 12.24¢ in May 2016 to 13.68¢ in May 2026.
- Highest and lowest month on record
- In this series the Missouri rate peaked at 15.91¢/kWh in June 2025 and bottomed at 5.87¢/kWh in January 2001. The series covers January 2001 to May 2026.
- Steepest 12-month increase
- The largest single-year move in the series ended in February 2023: the rate rose 19.5% (+1.85¢/kWh), from 9.51¢ in February 2022 to 11.36¢ in February 2023. That is when the change happened; the series does not say what caused it.
- Against the rest of the country
- Over the same window the unweighted average across the 51 jurisdictions with data for this period rose 34.4%, so Missouri's +20.2% lagged the nationwide move by 14.2 percentage points. That gap is the part of the movement this dataset cannot attribute to a nationwide trend — it does not identify what else was involved.
- Rank among jurisdictions (May 2021 → May 2026)
- Measured over that identical five-year window, Missouri's change is the 44th largest of the 51 jurisdictions whose series covers it — rank 1 is the biggest increase, rank 51 the biggest decrease. The rank places the movement; it does not explain it.
What can move rates in Missouri — context, not proof
A rate series shows what changed, not why. This dataset records Missouri's residential rate and nothing about what moved it, and no reviewed Missouri driver analysis is published yet — so this page makes no causal claim. The factors that generally move retail rates are documented separately.
The categories generally involved are generation mix, fuel costs, transmission and distribution investment, capacity markets, regulatory rate cases, demand growth, and weather-driven peaks. Which of them applies to Missouri, and by how much, is not something this price series can answer.
