How to calculate electricity consumption
With the arrival of peak electricity consumption in summer, how to calculate the electricity consumption of a home or business has become a hot topic. This article will combine the hot content of the entire network in the past 10 days to provide you with a detailed analysis of the electricity consumption calculation method and provide structured data reference.
1. Basic electricity bill calculation formula
Household electricity consumption is usually measured by an electric meter, and the basic calculation formula is as follows:
| Calculation project | formula | Description |
|---|---|---|
| total electricity consumption | This month’s meter reading – last month’s meter reading | The unit is kilowatt hour (kWh) |
| Basic electricity bill | Total electricity consumption × electricity price | Need to refer to local electricity price standards |
| tiered electricity bills | Calculate the electricity consumption of each step step by step | Most areas implement tiered electricity prices |
2. Reference for electricity prices in some areas in 2023
Based on recent hot data, the electricity prices for residents in major cities are compiled:
| area | The first electricity price (yuan/kWh) | Second level electricity price | The third level of electricity price |
|---|---|---|---|
| Beijing | 0.4883 | 0.5383 | 0.7883 |
| Shanghai | 0.617 | 0.667 | 0.917 |
| Guangzhou | 0.5921 | 0.6421 | 0.8921 |
| Shenzhen | 0.68 | 0.73 | 0.98 |
3. Electrical appliance power consumption quick check table
The electricity consumption statistics of electrical appliances that netizens are most concerned about recently:
| Appliance type | Power(W) | 10 hours of power consumption | Monthly power consumption (8 hours per day) |
|---|---|---|---|
| Air conditioner (1.5 HP) | 1100 | 11kWh | 264kWh |
| Refrigerator (double door) | 150 | 1.5kWh | 36kWh |
| TV (55 inches) | 120 | 1.2kWh | 28.8kWh |
| washing machine | 500 | 5kWh | 30kWh (3 times a week) |
4. Tips for saving electricity
Based on recent hot search content, we have sorted out the most popular power-saving methods:
1.Air conditioner usage tips: Set above 26℃, each 1℃ increase can save 6-8% of electricity; regular cleaning of the filter can save 15% of electricity.
2.Refrigerator optimization: Avoid opening the door frequently, keep the storage capacity at about 70%, and keep away from heat sources.
3.Standby power consumption: Long-term standby equipment such as routers and set-top boxes may consume 10-15kWh of electricity per month.
4.Peak and valley electricity consumption: Take advantage of the low hours at night (usually 22:00-8:00 the next day) to use high-power electrical appliances
5. New functions of smart meters
New functions of smart meters recently promoted in many places:
| Function | Description | Query method |
|---|---|---|
| Daily electricity consumption | Detailed daily power consumption curve can be viewed | Electric power APP/WeChat applet |
| Electricity bill warning | Set power usage reminder threshold | SMS/APP push |
| Appliance identification | Analyze electrical appliances that may be running during each period | Requires smart socket |
6. Calculation of special electricity consumption situations
Regarding the recently hotly discussed charging issues of new energy vehicles:
Electricity fee for household charging pile = battery capacity (kWh) × number of charges × electricity price
For example: 60kWh battery, charged twice a week, monthly electricity bill is about 60×8×0.6=288 yuan
7. Self-examination steps for abnormal electricity bills
According to the latest recommendations from power companies:
1. Check whether the current meter reading is consistent with the bill
2. Turn off all electrical appliances and confirm whether the meter is still running
3. Check whether there is any electrical leakage or short circuit
4. Compare the difference in electricity consumption during the same period in history
Through the above structured data and calculation methods, we hope to help you have a clearer understanding of electricity consumption calculation methods and rationally plan household electricity consumption. During the peak period of electricity consumption in summer, it is recommended to check electricity consumption data regularly to detect abnormalities in time.
