Estimate a bill at Maine rates
Worked example: 1,000 kWh at Maine's average rate of 32.11¢/kWh is about $321.10. The state's actual average usage is 489 kWh/month, which is what produces the $157.13 average bill. These are average effective rates including all charges; your utility's tariff will differ.
