How we got this

$1,785,631,900 residential revenue ÷ 10,308,608,000 kWh residential sales = 17.32 cents per kWh

Average price is revenue divided by sales, for full-service customers only. It averages every rate and every month, so one household's price can differ. State averages count revenue from every kind of service and sales only once, as EIA does.
