Several electric utilities are providing customers with a choice of billing procedures. Customers can select a time-of-day meter that registers electric usage throughout the day, or they can select a regular meter that registers total usage at the end of the day. With the time-of-day meter, the utility is able to charge customers a much higher rate for peak usage than for nonpeak usage. The regular meter users pay the same rate for electric usage no matter when it is used. Why would the electric utility want customers to choose the time-of-day meter?
