How the 13.37c figure is calculated

13.37c/kWh = $6,079k revenue / 45,463 MWh x 100. This is EIA's average realised price for 2024: everything City of Mayfield Plant Board billed its residential customers (energy, delivery, fuel and rider charges, fixed charges) divided by the kilowatt-hours it sold. It is not a tariff rate, and a 2024 annual average will differ from a current bill. For a 1,000 kWh month at this average, the energy cost works out to about $134 before taxes.

Source and method

Source: U.S. Energy Information Administration, Form EIA-861 Annual, 2024 final data (public domain), retrieved 28 August 2026; prices are average realised revenue per kWh, not tariffs. Final 2024 file f8612024.zip (released 3 December 2025) from the EIA-861 detailed data files. Preliminary 2025 figures come from the early-release file f8612025er.zip (4 August 2026), which EIA has not yet validated; they are labelled as such wherever shown and never mixed into a final figure.

Method: cents per kWh = revenue (thousand dollars) divided by sales (megawatthours), times 100. Customer counts, sales and revenue are the utility's own annual survey responses by state and sector. Bundled = energy plus delivery from one utility; delivery-only = the wires charge for customers who buy energy from a competitive supplier; energy-only = a competitive supplier's energy charge without delivery. County lists come from the EIA-861 Service Territory file; territory centroids used for "nearby utilities" are unweighted means of Census 2023 county centroids.
