The National Power System and Electricity Market Operator (NSMO) has just announced the operational status for May 23rd. Specifically, the peak power capacity of the national power system reached 53,512 MW (at 13:45), and the daily electricity consumption reached 1.116 billion kWh.
Notably, despite it being a Saturday, the peak power output of the North reached 26,562 MW (at 10:20 PM), setting a new record for 2026, 143 MW higher than the record set on May 15th.
Regarding the structure of electricity mobilization on May 23rd, NSMO reported that hydropower accounted for 27.4%; coal-fired thermal power 54.1%; gas turbines 5.1%; wind power 2.7%; solar power 4.8%; rooftop solar power (estimated) 4.1%; biomass power 0.4%; and other power sources 1.4%.
Regarding the operational situation on May 24th, data updated at 5 PM shows that the national load capacity during the afternoon peak (at 1:30 PM) reached 47,854 MW.
Despite it being Sunday, national electricity consumption reached the equivalent of 90% of a normal workday's consumption and was the highest level ever recorded on a Sunday (12.8% higher than the previous Sunday). In particular, the peak afternoon consumption in the North reached 24,722 MW. Due to the scorching heat, the National Power Grid Corporation (NSMO) ordered the start-up of expensive oil-fired thermal power plants, a 16% increase compared to the previous Sunday.
NSMO forecasts that at peak time, around 10 PM on May 24th, the national and northern power grid load will reach 49,200 MW and 26,800 MW respectively. Accordingly, the load in the North is expected to be about 300 MW higher than yesterday (May 23rd), potentially marking a new record consumption level for 2026.
According to the National Center for Meteorological and Hydrological Forecasting, intense and exceptionally intense heat is expected on May 25th, with maximum temperatures commonly reaching 38-40 degrees Celsius, and exceeding 40 degrees Celsius in some areas. The heat will last from 9 AM to 6 PM in areas from Thanh Hoa to Da Nang City and the eastern part of Quang Ngai province.
The Northern region continues to experience hot and intensely hot weather with temperatures generally ranging from 36-39 degrees Celsius. Hanoi is experiencing intense heat, with temperatures of 37-39 degrees Celsius, and some central areas exceeding 39 degrees Celsius (approaching 40 degrees). The heat lasts from 9 am to 6 pm; nights are muggy with temperatures of 29-32 degrees Celsius.
Accordingly, NSMO forecasts that the national power system's electricity consumption will reach 1.136 billion kWh, with the national power system's peak capacity at 9:30 PM reaching 53,503 MW.
To cope with the intense heatwave, NSMO has ordered the start-up of expensive oil-fired power plants S1 and S2 at O Mon I (running on fuel oil) to ensure availability for the national power grid and plans to connect them to the grid before 7:00 AM on May 25th to meet peak demand.
The remaining diesel-powered units, including S1-3, GT4-5 Thu Duc (DO), S4 Can Tho (FO), and GT1-4 Can Tho (DO), will continue to monitor load developments and be mobilized when necessary.
Previously, according to the power generation mobilization plan for May 23rd, oil-fired thermal power plants were not to be mobilized.
NSMO also recommends that people and businesses use energy economically and efficiently, especially during the peak dry season of 2026 and in the upcoming hot days.
