These are EIA's average residential prices: total revenue from residential customers divided by kWh sold. Delivery charges, fixed monthly customer charges, fuel adjustments and utility-paid taxes are all spread over every kWh, so the figure is close to an all-in rate (bill ÷ kWh). Your own utility, plan and usage tier can put you above or below it.
