How to use the energy calculator
To get an idea of your demand and rate, select the appliances your household tends to use at one time. It's easy to see how not using everything at the same time can reduce demand. To get an estimate of energy costs, enter the kilowatt hours based on a previous bill. Find that number on a recent bill or view your bill online.

The billing demand shall be the greater of the current month actual demand or 50% of peak actual demand established in the preceding eleven months.

As a point of reference, Platte-Clay's average residential consumption is 1400 kWh and the average demand is 8kW.
