In China, the ladder electricity price system is the basis of residential electricity consumption. When the electricity consumption of each household exceeds the electricity consumption of the first step, the electricity fee for the excess part shall be calculated according to the electricity price of the second step. Similarly, when the electricity consumption exceeds the electricity consumption of the second step, the electricity fee of the excess part is calculated according to the electricity price of the third step. Such a system can encourage residents to save electricity and improve energy efficiency.
According to the information you provided, your power consumption is currently within the scope of the first step, and the remaining power is 2402. This means that in your area, the first gear has a lower electricity consumption range and is suitable for lower electricity prices. At the same time, the remaining electricity is 2402, which means that your current electricity consumption is relatively low, so you don't need to worry about the high electricity bill.
It should be noted that the specific calculation method of electricity charges may be different due to different regions and policies. If more detailed information is needed, it is recommended to consult the local power company or relevant government departments.
