1. The 0, 1, 2, and 3 in the rate menu correspond to Sharp, Peak, Flat, and Valley rates, respectively. Customers can 

    choose to use Two or more of these rates;

2. The rate corresponds to the start time of the rate in that period. Similarly, customers can use only 2 or more of 

    these hours.

  For example

The sharp, peak, flat, valley time set as follows

  Peak hours

09:00-11:30

14:00-16:30

19:00-21:00

total 7 hours

);

  Flat hours

07:00-09:00

11:30-14:00

16:30-19:00

21:00-23:00

total 9 hours

);

  Valley hours

23:00- next time 07:00

total 8 hours

 Note: For correspondence, the corresponding multi-rate period is divided into 96 segments by 15 minutes per day 

for 24 hours a day, from 0-95,0 to   00:00 for a 24-hour system, and 95 to 24:45 for a 24-hour system, 

corresponding to the time It is the start time of the rate energy during this period.
