As far as I know, the peak and valley time division of electricity prices is to divide 24 hours a day into two time periods, namely the peak period and the valley period. The peak period refers to the 14 hours from 8:00 to 22:00*** every day, and the peak electricity price is applied; the valley period refers to the 10 hours from 22:00 to 8:00 the next day, and the valley electricity price 1 is applied. Power grid companies in different regions may specifically delineate each time period based on their respective seasons and the timing of peak and valley loads.
