EVN has just sent an updated report on the power supply situation in the North to the Prime Minister and Deputy Prime Minister.
Notably, in the report, EVN stated: Based on weather forecast information, the North will cool down and maintain the temperature at 32-33 degrees Celsius from June 13 to June 17, but from June 18 to June 23, the heat will increase to 36-37 degrees Celsius, and after June 24, the temperature will decrease to 33-35 degrees Celsius. In the coming time, the water in hydroelectric reservoirs has not improved much, there is no information about flooding in the lakes in the North.
EVN estimates that in the coming week from June 17 to 24, the capacity that cannot be met in the North will be about 2,000-2,500 MW and will depend largely on the heat level as well as the water situation in hydroelectric reservoirs. Therefore, it is necessary to continue to reduce electricity demand until water flows to hydroelectric reservoirs.

Regarding the electricity supply situation from June 1-15, EVN said that fuel supply for coal-fired thermal power plants nationwide has been ensured. Oil-fired power plants in the South have stopped and do not need to be mobilized. Meanwhile, hydrological conditions in the first days of June continue to be poor.
EVN has mobilized the maximum thermal power sources in the North, increasing the transmission limit from the Central and South to the North to the highest (2500-2700 MW), however, the total power capacity still cannot meet the demand in the North. In that situation, to ensure the safe operation of the power system, EVN has allocated available capacity to the Power Corporations, the Power Corporations have allocated to the provincial power companies in compliance with the regulations in Circular 34/2011/TT-BCT dated September 7, 2011. The available capacity for the days from June 1 to June 9 was 17,000 MW and from June 10 to now it has increased to 18,000 MW.
During June 9-13, hydrological conditions improved due to widespread rain in the northern river basins, so the water levels in lakes are now above the dead water level.
At the same time, the temperature in the North has also cooled down, so on June 13-15, the Hanoi area did not have to reduce electricity. For the remaining areas of the North, the reduction has gradually decreased and by June 15, the average reduced capacity was only 1,319 MW, accounting for about 5.7% of the used capacity.
The latest information in the report of the Department of Industrial Safety Techniques and Environment (DAST) just sent to the Minister of Industry and Trade on the operation of hydroelectric reservoirs shows that, in addition to the 4 hydroelectric reservoirs near the dead water level mentioned above, there are a number of reservoirs with low water levels: Son La, Hua Na; a number of hydroelectric plants are generating electricity at a moderate rate with low flow, water level, and capacity: Son La, Huoi Quang, Ban Chat, Thac Ba, Tuyen Quang, Hua Na, Thac Mo, Dong Nai 3.
The report of the Department of Water Safety also said that on June 17, the flow to hydroelectric reservoirs was low. The South Central Coast region increased slightly compared to yesterday. The water level of hydroelectric reservoirs in the North and North Central regions also increased slightly; The water level in the Southeast region fluctuated slightly, still at a low level; The water level of the reservoirs in the South Central Coast and Central Highlands regions decreased slightly, within the minimum water level range according to the regulations of the operating procedure.
The amount of water flowing into the reservoir is mainly to regulate the water to ensure the minimum flow, hydroelectric plants operate to generate electricity based on the water flow, plants in the Northern and North Central regions generate electricity at a moderate rate with low flow, water level, and capacity to ensure the safety of the generators during operation, it is difficult to meet the electricity generation according to the reservoir operation process at this time and the forecast of low water flow into the reservoirs in the coming time.
