What is the reason for the sudden increase in electricity bill in June, not just from the hot weather?
In recent days, many households in Hanoi and other areas have reported that their electricity bills for June 2025 have increased dramatically, with some places being 2-3 times higher, forcing the Hanoi Electricity Corporation to speak up to explain the cause.
Living in an apartment building in Tay Mo Ward, Hanoi, Ms. H. said that her electricity bill in June was double the normal price. Meanwhile, she said that in June she was on a business trip for 10 days, meaning that the actual time she used electricity in her house was less than in previous months.
On social networks, many users also expressed surprise at this unusual increase. Dinh Lien commented: "Average monthly is 1.2 million VND - 1.5 million VND, this month it's almost 3 million VND. Shocking."
Similarly, LT account shared: "Last month, my family used 1.2 million VND of electricity normally. And there were only 2 of us. This month, I was away for the whole month, so I unplugged some of the refrigerators. Luckily, this month it went up to 2.1 million VND."
Summer holiday factor contributes to increased electricity consumption
Responding to this issue, Hanoi Electricity Corporation (EVNHANOI) said that June 2025 recorded a clear increase in temperature in Hanoi, with the average temperature increasing from 2 to 6°C compared to May.
In particular, during the peak hot days of early and mid-June, the outdoor temperature reached 41°C, the actual felt temperature even reached 52°C.
Prolonged high temperatures not only affect daily life but also increase the demand for electricity, especially cooling devices such as air conditioners, fans and refrigerators. This situation causes a sharp increase in electricity consumption throughout the city, especially in residential areas.
EVNHANOI informed: "In particular, when students' summer vacation coincides with the peak of hot weather, it leads to continuous use of air conditioners and electrical equipment day and night." The fact that students stay at home during the summer vacation has significantly increased the time of using electrical equipment, especially cooling systems.
In addition, high temperatures not only increase the frequency of electricity use but also make cooling devices consume more energy to maintain operating efficiency. When the temperature difference between indoors and outdoors is large, the air conditioner must operate continuously, with few interruptions, leading to increased electricity consumption even though the usage time remains unchanged.
Factors adjusting electricity prices
In addition, the adjustment of retail electricity prices according to Decision 1279/QD-BCT from May 10, 2025 with an increase of 4.8% at all levels is also a factor causing the electricity costs of households in June to increase.
This is one of the important reasons contributing to the increase in electricity bills that many people are not fully informed about.
The combination of a sharp increase in electricity consumption due to the weather and a 4.8% increase in electricity prices has created a double effect, causing people's electricity bills to spike compared to previous months.
To effectively control electricity costs, people need to change their electricity usage habits in the summer. Regular maintenance of air conditioners, using curtains to block heat, and taking advantage of cooler temperatures to reduce the time of using air conditioners will help save significantly.
In addition, people should closely monitor their daily electricity consumption through electricity industry applications to promptly detect and adjust when there are abnormalities. Understanding the ladder electricity price structure also helps people plan their electricity usage more reasonably.
