Frequently asked questions

How do I calculate my monthly electric bill?

Multiply monthly kWh by your electric rate, then add customer charges, delivery charges, other fees, and taxes.

Why is my bill higher than kWh times my rate?

Electric bills can include fixed service charges, delivery charges, riders, fuel adjustments, minimum charges, taxes, and other utility fees.

How do I estimate monthly kWh from watts?

Divide watts by 1,000 to get kilowatts, multiply by hours used per day, then multiply by billing days.

What is an effective electric rate?

The effective rate is your total monthly bill divided by total kWh. It includes fixed fees and charges, so it may be higher than your listed energy rate.
