Estimate a bill at Oklahoma rates
Worked example: 1,000 kWh at Oklahoma's average rate of 14.82¢/kWh is about $148.20. The state's actual average usage is 1696 kWh/month, which is what produces the $251.28 average bill. These are average effective rates including all charges; your utility's tariff will differ.
