<p>620322 Disclosed is a device for estimating electricity consumption cost from a current time to an end of a current billing period based on usage data received from an electricity meter. The device comprises a database for storing electricity usage data received from the electricity meter, and a computer processor. The computer processor is configured to calculate, based on the retrieved usage data, an average hourly electricity consumption cost for a predetermined number of previous days. The processor is also configured to calculate, based on the retrieved usage data, an average daily electricity consumption cost for the predetermined number of previous days. The processor then calculates the number of days remaining until the end of the current billing period and multiplies the number of days remaining with the average daily electricity consumption cost to provide an estimate of electricity consumption cost for remaining days of the current billing period. The processor also subtracts the hour of the current time from twenty-four and multiplies the result with the average hourly electricity consumption cost to provide an estimate of electricity consumption cost for remaining hours in the current day. The processor is configured to then add the estimate of electricity consumption cost for remaining hours in the current day to the estimate of electricity consumption cost for remaining days of the current billing period to provide an estimated electricity consumption cost from the current time to an end of the current billing period. This estimated cost may be presented to a user on a display of the device.</p> |
