In that context, the EVNHANOI App becomes an indispensable tool to help customers proactively monitor, control and use electricity effectively.
Many reasons for increasing electricity bills
June 2025 recorded a significant increase in temperature in Hanoi , with the average temperature increasing from 20C to 60C compared to May. In particular, during the peak hot days in early and mid-June, the outdoor temperature reached 410C, and the actual feeling even reached 520C. 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.

According to statistics from Hanoi Electricity Corporation (EVNHANOI), in June 2025, the average daily electricity output in Hanoi reached more than 90 million kWh, an increase of 12% over the same period in 2024. The total output in June approximately 2,700 million kWh, of which the peak was recorded on June 2 with 110.9 million kWh - the highest since the beginning of the year. The group of customers using electricity for daily life accounted for more than 59.5% of the total output, an increase of 1.15 times compared to May. This reflects the direct impact of the weather on electricity usage behavior in households. In particular, the summer vacation of students coincides with the peak of hot weather, leading to continuous use of air conditioners and electrical equipment day and night.
High temperatures not only increase the frequency of electricity use, but also cause cooling devices to 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. In addition, the adjustment of retail electricity prices according to Decision No. 1279/QD-BCT, dated May 9, 2025, regulating electricity prices of the Ministry of Industry and Trade , effective from May 10, 2025, with an increase of 4.8% at all levels of electricity consumption, is also a factor that causes the electricity costs of households in June to increase.
Useful technology solutions with EVNHANOI App
In the context of increasing electricity bills, the EVNHANOI App has become a powerful assistant to help people control electricity consumption, manage spending and adjust electricity usage behavior scientifically . Instead of passively waiting for the bill at the end of the month, users can monitor daily electricity consumption, compare usage by period and promptly detect fluctuations. In particular, the warning threshold setting feature will automatically send notifications if consumption exceeds the set threshold, helping you proactively adjust "tighten" when necessary.
Not only helping to control electricity consumption, the EVNHANOI App is essentially a personalized support system - where customers can monitor, analyze, pay, reflect, receive notifications and interact with the electricity industry right on their phones. Things that used to require "having to go there", "having to call", "having to wait for hours" are now just a few taps away.
In terms of information, the application is also doing a good job as a transparent and fast communication channel. Notifications about power outages, electricity prices, etc. are sent to users in each area, helping them to proactively arrange their work and daily activities without being surprised. In the summer, when electricity consumption increases sharply, this feature is even more effective.
In reality, many customers said that the EVNHANOI App has helped them significantly change their electricity usage habits. Mr. Mai Ngoc Trinh (Hoang Mai Ward, Hanoi) used to have a "bad feeling" about the monthly electricity bill. Not because the amount was too large, but he shared that it was because he felt passive, unable to know how much he had used, not knowing why it increased this month, why it decreased that month. Every time there was a sudden power outage, he didn't know why, when it would come back. "I used to think that using electricity was a default. Turn it on, it was there, paid at the end of the month, that's it," he shared. But then everything changed since he installed the EVNHANOI App.
For Ms. Le Thi Kim Ngan (Yen Hoa ward, Hanoi), installing the EVNHANOI App is like adding a small electricity meter to her phone. “I used to not know how much I used until the electricity bill was sent. But since having the App, everything is clear. I set the consumption threshold according to my desired monthly spending level. When I get close to that level, the App will notify me immediately.” No longer waiting until the end of the month to be surprised by the bill, Ms. Ngan said that now monitoring electricity is like checking her bank account, “knowing to adjust, to reduce stress and to be less passive”. For her, this convenience helps the whole family form the habit of saving electricity easily.
It is worth mentioning that the EVNHANOI App interface is not complicated. Designed to be minimalist and easy to use, this application is suitable for all audiences, including the elderly who are not familiar with technology. This helps expand accessibility to even those who rarely use high-tech platforms. Customers can easily download the EVNHANOI App to their phones at: http://dl.evnhanoi.vn.
Saving electricity not only helps reduce living expenses, but also contributes to protecting energy resources and reducing pressure on the capital's power system during peak season. With the EVNHANOI App, monitoring and electricity becomes easy, transparent and proactive, a useful technology solution that every family should install this summer.
