Heat is the main culprit causing high electricity bills due to a sharp increase in electricity demand. People need to regularly monitor electricity usage and promptly adjust their living habits when they see an unusual increase in consumption. Download Heat is the main culprit causing high electricity bills due to a sharp increase in electricity demand. Throughout May, the electricity system continuously recorded record peak capacity, especially in the Northern region. May 25 marked the strongest increase in electricity load since the beginning of 2026. According to NSMOs report, the national load capacity at 13:40 reached 57,120 MW; The North set a new record of 29,667 MW, an increase of nearly 11.5% compared to the previous peak. May 26 is considered the peak of the heat wave in early summer 2026 when the national and Northern power systems simultaneously set new records in both maximum capacity and electricity consumption. The national maximum capacity reached 58,103 MW at 13:40, an increase of about 5.7% compared to the peak in 2025. In the North, the maximum capacity reached 29,716 MW at 13:20, an increase of 5.4% compared to the record in 2025. Electricity consumption reached 629 million kWh, 5.4% higher than the previous years record. Compared to the same period in 2025, electricity output in the North will increase by 25.4%, while maximum capacity will increase by 26.4%. On May 27, the load on the Northern power system at 13:15 reached approximately 29,800 MW, of which, the Northern Power Corporation and Hanoi Electricity Corporation implemented load adjustment (DR) with a total capacity of about 300-400 MW and mobilized the Customers diesel sources. How to use electricity properly? Heat is the main culprit causing high electricity bills due to a sharp increase in electricity consumption demand. Northern Power Corporation (EVNNPC) said that from May 23 until now, the Northern region has entered the first and most intense heat wave since the beginning of summer 2026. Temperatures in many Northern localities are commonly between 37-39 degrees Celsius, many places above 40 degrees Celsius. In large urban areas, the heat absorption effect from concrete structures and buildings with large glass areas causes the perceived temperature to exceed 50 degrees Celsius. Notably, the hot weather that lasts all day and night causes the need to use cooling equipment such as air conditioners, electric fans, refrigerators... to increase dramatically. It is forecasted that in the coming time (from June to August 2026) there will still be heat waves. lasting nationwide, especially in the Northern region. To proactively control electricity costs during the hot season, EVNNPC recommends that customers regularly monitor electricity usage and promptly adjust living habits when they see an unusual increase in consumption. Accordingly, people should set air conditioners at 26degC or higher, combined with using fans to increase cooling efficiency; Close doors when using air conditioning; Periodically clean cooling equipment; Turn off electrical equipment when not in use; Limit turning on many high-capacity devices at the same time during peak hours. For agencies, businesses and manufacturing facilities, it is necessary to review loads, arrange appropriate production plans, check internal electrical systems and large power-consuming devices to reduce power loss, save costs, avoid high electricity bills and ensure safe operation. In addition to power-saving solutions, EVNNPC also encourages households and businesses... to research and install the system Rooftop solar power is self-produced and self-consumed. This solution helps take advantage of solar energy during the day, reducing the amount of electricity purchased from the national grid, thereby contributing to reducing electricity costs and moving towards the use of green, sustainable energy. According to EVNNPC, using electricity economically and efficiently, combined with green energy solutions, not only helps people and businesses control electricity bills during the hot season, but also contributes to reducing pressure on operating the electricity system, ensuring safe and stable electricity supply to serve life. people and production and business activities in the Northern region. Proactively monitoring daily electricity output, using appropriate cooling equipment, researching investment in installing rooftop solar power and practicing electricity saving right from the beginning of the hot season will avoid high electricity bills in the coming months, EVNNPC emphasized.
