May. Measured over the 25 complete calendar years the EIA series covers for Mississippi, 2001 through 2025, May runs highest relative to its own year and January runs lowest — a swing of roughly 11.3 percentage points.

Almost certainly not exactly, and this is the one caveat that governs every figure on this page. The published value is the EIA residential average across every utility and residential rate class in Mississippi for May 2026 — a benchmark, never a billed amount. Even the jurisdiction figure is not one number — across the trailing year it moved between 13.58¢ in July 2025 and 16.76¢ in April 2026. Your own rate depends on your utility, tariff, usage tier, time-of-use schedule, and fixed monthly charges, none of which this index models. Read your bill for the rate that applies to you.
