General Information:
Rates effective 7/1/01 form the basis for these calculations. City Light rates are structured to provide an initial block of inexpensive electricity to cover basic life needs such as cooking, hot water and refrigeration; a second block to cover additional needs of most users; and a higher-priced third block for large users. At rates in effect July 1, 2001, customers are billed $0.0372 per kWh for the first 300 kWh used per month (480 in winter). Customers are billed $0.0805 per kWh for second block use of 301-1800 kWh per month (481-3750 in winter). Customers are billed $0.1600 per kWh for third block use of all over 1800 kWh per month (3750 in winter).
The calculations in this table are based on the current second block rate of $0.0805 per kWh. High users should substitute the third block rate in these calculations.
Wattage figures may vary. Wattage is generally specified on the appliance.
