We are getting closer to summer and the consumption of electric cooling is peak. As the country is facing an unprecedented power shortage, the likelihood of electricity bills will be several times as high as the previous year. Now, it doesn’t matter what intent you come here, whether for fear of electricity or to help reduce consumption, you should either know the peak hours of summer electricity consumption; So keep up with us.
Peak hours of electricity consumption in the summer
Power consumption at peak hours is about 2.5 times that of normal, why? Because almost everyone is using electrical and cooling at the same time during the summer’s peak hours, this is why the electricity grid across Iran is under pressure and consumption.
There are two main peaks in the summer:
12 noon to 18pm
At noon to evening is the peak of the hell of summer and cannot be returned to 50 years ago and not use the fan and cooler! At the same time, both businesses and private offices are active, and electricity pressure is multiplied.
19 evening to 23 nights
From evening to night, the weather is a little cooler but it is not possible to turn off cooling equipment; Finally, the grade of cooler and fan changes from high to average. At this time, in addition to cooling equipment, lamps and lights are also bright, and this is the second high -end of summer electricity consumption.
Summary Table Hours Peak Power Consumption in Summer
Based on the table below, you can find the peak hours of electricity consumption this summer, as well as the best hours to use electric appliances.
There is a concept in Table 3 for more understanding:
- Low hours: When power consumption is minimized. Half of the night and morning is the best time to use high -powered electric appliances.
- Intermediate hours: These hours are time when electricity consumption is relatively average.
- Hours of peak load (peak consumption): When power consumption reaches its highest.
| Category Category Power Consumption in Summer | Hours | Explanation |
| Low | 3 in the morning to 8am | The best time to turn on the high -powered items |
| Between the load | 9 to 13 – 19 to 2am | The right time to use electrical appliances with conventional consumption |
| Peak consumption | 14 to 18 | Only use of essential electrical appliances |

The best time to consume home electricity in the summer
The best time to consume home electricity in the summer is in the mid -time and low -cost hours. For example, the best time to turn on high -powered machines such as a washing machine and dishwasher is when the city is asleep or the streets are left alone. That is, around 3am to 10am.
Hours of the day, especially from 12 noon to 18 pm, are all working and living in everyday life. This is a critical time for electricity consumption. It is best to only turn on the essentials during this period. Put the air conditioner to the point where you do not heat up and turn off the extra lights.
Nights are high from 19 to 23 pm. If we can transfer the use of unnecessary electrical appliances to an hour other than these hours, we will both pay less and help the power grid stability.

The best time to use the utilized electrical appliances
Let’s first introduce high -end electrical appliances; Washing machine, dishwasher, ironing, vacuum cleaner, food processor, rice cooker, microwave, mixer and even air conditioner. Each air conditioner consumes approximately 6 water cooler. Now if these high -end utensils are clear during the peak hours, you should not be surprised to see the astronomical bill.
Now we get to the main question; Who is the best time to use high -powered electrical appliances? The answer is very simple: when everyone is asleep or at least consumed. That is, about 3am to 10am.
The use of high -powered electrical appliances is not recommended at 12 to 18 and 19 to 23 hours, as the power grid is most likely and the cost of the electricity is 2 and a half times the normal.
| Electric device | The best time to use |
| Cooler | 1 morning to 11am |
| Fan | Whenever (less consumed than cooler) |
| Washing machine | 3 in the morning until 10 am |
| Dishwasher | 3 in the morning until 10 am |
| Otto | 1 in the morning until 10 am |
| Vacuum Cleaner | 7 am to 10 am |
| Microwave | 23 nights to 10 am |
| TV and audio system | 23 nights to 10 am |
| Lamps and lighting | Whenever (be sure to use a low consumption type) |

Important points to reduce power consumption in the summer
Take a small step in reducing power consumption in the summer with the following:
- Turn on the air conditioner only when needed: Don’t forget to turn off the cooler when you get out of the house. The best temperature for air conditioner is between 25 and 26 degrees. Don’t make it less.
- Electric appliances with energy consumption A+: If you have bought your electrical appliances that nothing, but if you haven’t bought, just look for A+ energy labels, as they consume about 15 % less electricity.
- Insulate the doors and windows: Do not forget to insulate the doors and windows to prevent the cooler from being wasting out.
- Regularly clean the filter and the cooler valve: A dirty filter means wasting electricity, so be sure to clean the filter every 2 months.
- Open the windows at night: If the air is cool, use natural ventilation.
- Choose the right cooling device: The power consumption of cooling devices is as follows: Gas Cooler> Blue Cooler> Fan. So, depending on the degree of air, follow this law and use as much as possible the water and water cooler.
The last word
In this post we were fully acquainted with the peak hours of the summer electricity consumption; So never use unnecessary electrical appliances between 1pm to 6 pm and 6pm. Beyond that, the most important thing is that each of us can make a huge contribution to reducing power consumption with small changes, such as turning off an additional lamp or optimizing use of cooler. So let’s do ourselves instead of relying on others and make a cooler and brighter summer together.

Frequently asked questions
What are the peak hours in different provinces?
The peak hours of electricity consumption in different provinces of Iran are almost similar, and only a slight difference between about 1 to 2 hours. For example, the peak hours of Tehran’s electricity consumption last summer from 12 to 18 pm and again from 19 to 23; But in Fars province, these intervals are slightly displaced and are considered from 12 to 17 and then 20 to 24. This minor difference goes back to the climatic conditions of each region.
What is the difference between the peak hours of the summer electricity and other seasons?
In the summer and the first half of the year, both peak hours are higher and power consumption is higher, which is why the peak of power consumption is from 12 to 18 and again from 19 to 23. In the second half of the year, the peak of electricity consumption is in the evenings and from 19 to 23.
How much did the electricity bill increased in the summer of 1404?
The electricity bill in the summer of 1404 has increased by about 26% compared to the previous year, and this tariff will apply from June 1st.
