Rate against consumption: Missouri utilities

Each dot is one of the 46 Missouri utilities reporting both a residential price and residential sales in 2024, placed by its rank percentile within that group rather than its raw value, so one very large utility cannot flatten the rest. Bubble size follows customers served, rank-scaled so a utility with millions of customers cannot swamp the rest. Union Electric Co - (MO) is highlighted. In Missouri the cheapest rate belongs to City of Sikeston - (MO) (9.88¢) while the smallest implied annual bill belongs to Sunnova ($1,100) - a household's bill is price multiplied by consumption, so the two rankings are different lists. 2×2 strategic matrix plotting 46 entities by Price rank percentile (100 = most expensive in state) (X) and Consumption rank percentile (100 = heaviest use) (Y), with a crosshair dividing the plot into four quadrants.
