Average bill = rate × average usage. Utilities with similar rates can show very different average bills because their customers' average usage differs (housing mix, heating fuel, climate).
Estimate a bill at Hawaii rates
Worked example: 1,000 kWh at Hawaii's average rate of 47.18¢/kWh is about $471.80. The state's actual average usage is 570 kWh/month, which is what produces the $269.05 average bill. These are average effective rates including all charges; your utility's tariff will differ.
