1 For the first 10 kWh per day on average in summer or 16 kWh per day on average in winter, you pay the rate of $0.0376 per kWh. 2  For additional use over 11 kWh per day on average in summer or over 17 kWh on average in winter, you pay the rate of $0.0793 per kWh.OTE: The normal billing period ranges from 57-63 days. To figure the average kWh use per day, Seattle City Light takes the total number of kWh used and divides by the number of days in the billing period.
Now you know how many kilowatt-hours (kWh) the device uses every day. To calculate your kWH per month or per year, just multiply by the number of days in that period. Example: Over the course of a 30-day month, your fan would use (1.25 kWh / day) x (30 days / month) = 37.5 kWh per month.
