Frequently Asked Questions

Answers to common questions about calculations, rules, and practices.

Multiply the appliance wattage (W) by the hours used per day and divide by 1,000 to get kilowatt-hours (kWh). Then multiply the kWh by your total electricity price (energy price + grid distribution transfer fee in cents/kWh).
