Rate against consumption: Connecticut utilities

Each dot is one of the 13 Connecticut 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. Connecticut Light & Power Co is highlighted. In Connecticut the cheapest rate belongs to Town of Wallingford - (CT) (15.65¢) while the smallest implied annual bill belongs to Tesla Inc.
