What are the peaks and valleys of electricity bill?

Simply put, the peak value of electricity charge refers to the peak period of electricity consumption, and the valley value refers to the low period of electricity consumption. And the peak and valley electricity prices are different.

Peak-valley time-of-use electricity price is used to adjust power load distribution and relieve peak load pressure of power grid. The load is uneven in a day, and there is a peak in day and night, an early peak and a late peak. Because the power supply capacity of the power grid is limited, it is unbearable for the power grid to use electricity centrally during peak load, but no one often uses electricity during peak load at night.

In order to alleviate the pressure of power supply in peak period and encourage power consumption in low period, all localities divide load sections according to the load situation of power grid, and encourage different electricity prices to balance power consumption in each period. Generally, the peak-valley electricity price is the highest, followed by the flat peak electricity price, and the valley electricity price is the lowest. Multiply the peak electricity price by the peak electricity consumption to get the peak electricity price, and multiply the peak electricity price by the valley electricity consumption to get the valley electricity price.

Expanding the peak-valley electricity price system of data can give full play to the economic leverage of price and mobilize the enthusiasm of users to cut peaks and fill valleys and balance electricity consumption. The application of peak-valley electricity price has eased the contradiction between power supply and demand, improved the load rate and equipment utilization rate of power grid, and achieved the purposes of controlling peak load, making full use of low-valley electricity in power grid, fully tapping the potential of power generation and supply equipment and comprehensively improving the economic benefits of the whole society.

Division and editing of peak and valley periods: every day is divided into three periods, and each period is 8 hours. According to this principle, each power supply company can specify each time period according to its own season and the time when peak and valley loads appear.

The implementation of Guangxi Power Grid is as follows: 7: 00 ~ 1: 00,19: 00 ~ 23: 00 during daily peak hours; The normal time period is11:00 ~19: 00; The trough period is from 23: 00 to 7: 00 the next day. The peak and valley periods of northeast power grid are divided into: peak period: 8: 00 ~ 1 1: 00,1:00 ~ 21:00; Low valley time: 22: 00 ~ 5: 00 the next day; The rest time is normal time, and all the above time periods are Beijing time.

Editor: If the price difference between peak and valley electricity prices is too small, the marginal utility of peak and valley electricity prices will be reduced, consumers' desire to regulate consumption behavior will be low, and the advantages of peak and valley electricity prices will not be reflected. On the contrary, if the price difference is too large, the profit of the power company may decline, which is also impossible to implement.

Although the peak-valley electricity price has many advantages, it will take some time for people to change their long-term electricity consumption habits, which increases the difficulty of adjustment. On the other hand, industrial electricity accounts for more than half of the total electricity consumption, which will prompt power supply enterprises to ignore the implementation of peak-valley electricity prices among civil electricity users in order to save transaction costs. The government should increase publicity to promote the implementation of peak-valley electricity prices in a wider range.
