📋 Tender Overview
The particularly intense heat wave on a large scale in the Northern and Central regions in recent days has put great pressure on the national electricity system due to increased demand for electricity. In these extremely harsh weather conditions, transmission workers are straining to ensure the safety of the power grid. From May 25, the Northern and Central regions entered a severe heat wave, especially intense on a large scale. In many areas, common temperatures range from 38-40 degrees Celsius, with some places exceeding 40 degrees Celsius; Hanoi alone maintains a temperature of 37-39 degrees Celsius, the central area has some places approaching 40 degrees Celsius, the hot period lasts from 9:00 a.m. to 6:00 p.m. Accompanying the extreme weather developments is huge pressure on the national electricity system as the demand for electricity increases. To ensure the availability of power source to serve the increased load, the National Power System and Electricity Market Operating Company (NSMO) has mobilized large-capacity backup oil-burning generating units to enhance the ability to meet load demand during the peak dry season of 2026. Download Continuously check the operating status and load carrying of equipment at Thanh Cong 220kV substation - Photo: PTC1Follow the direction of the National Power Transmission Corporation (EVNNPT) and operating plans for the dry season in 2026, Power Transmission Company 1 (PTC1) has synchronously deployed many solutions to ensure safe, continuous, and stable operation of the transmission grid under conditions of high load and extreme weather. Accordingly, from the beginning of the dry season, PTC1 has proactively reviewed operating methods, increased equipment inspection, and handled problems and defects; Deploy solutions to prevent heat generation at critical points; Applying technology such as thermal scanning, UAV flying equipment, online equipment cleaning; Strengthen the response force, fully prepare materials and vehicles according to the motto 4 on site, 3 ready to ensure the ability to safely transmit electricity in all situations. Continuously cool, closely monitor operating status, load equipment On May 25 at key operating points of PTC1 such as Thanh Cong 220 kV substation (substation), Thuong Tin 500 kV substation and 500 kV line area Thuong Tin - Ha Dong carries a high load, the operating force has maintained an enhanced duty mode, closely monitoring the equipment load status. Download Equipment at the station is regularly cooled - Photo: PTC1 In the midst of an outdoor temperature of approximately 50 degrees Celsius, the sweaty orange shirts of the operators still persevere at the station and on the route; diligently spraying water to cool transformers, continuously checking the operating status of equipment, and detecting heat emission at connection points at the distribution yard. At the same time, increasing vigilance in areas intersecting with national highways, construction sites, and locations with potential risks of violating the grid safety corridor to proactively prevent incidents. Sharing about the operation during the time of high load, Mr. Chu Xuan Khoat - Head of the Mobile Operation Team of 500 kV substation Thuong Tin said: On peak hot days, the load increases sharply, causing great pressure to operate the system.

Methods The project to respond to unusual situations is always in a ready state to ensure the power transmission system operates safely and continuously, Head of the Mobile Operation Team of 500 kV Thuong Tin substation further informed. According to Mr. Chu Xuan Khoat, in addition to periodic inspection, the operating force also proactively enhances heat detection, monitors equipment temperature, closely coordinates with relevant units to promptly handle risks that may affect system operation, and is determined to Maintaining a safe electricity flow to serve socio-economic development and peoples daily needs during the peak period of the dry season in 2026. In particular, the recent commissioning of additional projects to enhance transmission grid capacity such as transformer AT7 at Ha Dong 220kV substation, conversion of AT3, AT4 at Thanh Cong 220kV substation has contributed to improving the reliability of electricity supply to the Capital during the period of increased load due to hot weather.

Heat wave This particularly severe situation is forecast to continue in the next 2-3 days. In the context of a sharp increase in load and severe weather, the efforts of the power transmission force have contributed to maintaining the national energy lifeblood, ensuring safe and continuous transmission of electricity.socio-economic development and peoples lives.
