📋 Tender Overview
Prolonged heat is increasing worries about electricity bills for many families. When outdoor temperatures continuously remain high, the need to use cooling equipment such as air conditioners and electric fans increases sharply, causing domestic electricity consumption to increase significantly. Download EVNCPC said that although the heat has not yet reached its peak, electricity consumption has begun to heat day by day. The maximum capacity Pmax on May 15, 2026 reached 4,590 MW, setting a new peak in 2026. Demand for household electricity increased sharply. According to the National Center for Hydro-Meteorological Forecasting, from April to September 2026, heat waves tend to increase in both intensity and scope nationwide. This phenomenon appeared as early as April, expanding in the Northern and Central regions from the end of May. In particular, in the months of July-September 2026, the number of hot days is forecast to be more and more intense than in 2025. Recorded in Da Nang, right from the beginning of May, the weather turned hot, many households used cooling devices such as air conditioners, electric fans, and increased the frequency of use in daily life. active every day. Ms. Nguyen Thi Thu (Thanh Khe ward) said that due to the heat, her family had to use air conditioning to ensure sleep for the elderly and children. In the summer, my children stay home from school a lot, so the air conditioner often works all day, and the fan also runs continuously. Electricity bills nearly double, said Ms. Huynh Thi Kim Phuong (Cam Le ward). According to the Central Power Corporation (EVNCPC), although the heat has not yet reached its peak, electricity consumption has begun to heat day by day. This is a reality that is happening in many households when the demand for electricity increases rapidly right from the beginning of the season. During the hot season, domestic electricity output can increase compared to normal months, creating great pressure on the electricity supply system. At the Corporation, the maximum capacity Pmax on May 15, 2026 reached 4,590 MW, setting a new peak in 2026. Download The electricity industry guides people to use electricity economically and effectively during the hot season. Cooling equipment - the main culprit causing high electricity consumption. Talking about this issue, Mr. Nguyen Huu Khanh, Deputy General Director of EVNCPC, said that in the hot season, the increased use of air conditioners and cooling equipment is the main reason why many households electricity bills increase sharply. Associate Professor, PhD. Nguyen Viet Dung (Hanoi University of Science and Technology) - an expert in heat and refrigeration engineering, said that in the households electricity usage structure, cooling devices, especially air conditioners, always account for a large proportion, possibly up to 40-70% of total electricity consumption during the hot season. These are actual technical specifications that show that just a small change in air conditioning usage habits will create a big impact on the total power consumption of the entire system. Besides, the cause is not only due to increased frequency of use but also due to unreasonable habits of operating the device. Setting the air conditioner at too low a temperature, using multiple high-capacity devices at the same time, or not ensuring room tightness causes the machine to operate continuously at high intensity, significantly increasing power consumption. According to Associate Professor, PhD. Nguyen Viet Dung, people can completely control this cost by adjusting their usage behavior. Specifically, the air conditioner temperature should be set at 26-28degC, combined with the use of fans to increase the efficiency of cold air circulation; Limit the simultaneous use of multiple high-capacity devices during peak hours; Turn off devices when not needed and prioritize using devices with energy saving labels. In addition, ensuring room tightness when using air conditioning, using sunshades to limit heat radiation, cleaning equipment periodically and monitoring daily electricity consumption are also simple but highly effective solutions in reducing electricity costs. Increasingly extreme weather leads to increased demand for electricity. Therefore, using electricity economically and effectively not only helps reduce living costs but also contributes to reducing pressure on the electrical system, ensuring stable electricity supply during prolonged hot days. 5 ways to help reduce electricity bills in the hot season: Set the air conditioner at 26-28degC, combine with a fan to increase cooling efficiency Close the room, use sunshades to limit heat loss Clean equipment periodically to save energy Limit the use of high-capacity equipment during peak hours Turn off electrical equipment completely when not in use Nhat Anh See moreElectricity consumption sets a new peak: Recommend that people use electricity economically See moreElectricity consumption The whole country exceeded the milestone of 1.1 billion kWh
