Electricity of Vietnam (EVN) has just sent a report to the Prime Minister on the situation of electricity supply in the first half of June.
In the report, EVN said that it has implemented many solutions and achieved certain results. Currently, EVN is able to ensure electricity supply to all provinces and cities in the Central and Southern regions from Ha Tinh onwards (36/63 provinces and cities).
But due to the very poor water condition of the northern hydropower reservoirs, from June 1, EVN had to regulate the load and reduce electricity in the North.
According to the weather forecast, from June 18, the North will increase heat again and maintain a temperature of 6-36 degrees Celsius for nearly a week. Although the water level of hydropower reservoirs has improved, it is still at low level and there is no flood information on lakes in the North. Therefore, EVN said that it still has to reduce the demand for electricity until there is water in the hydropower reservoirs.
EVN expects the cut in the North next week to be 2.000-2.500 MW. However, this level is about 20-30% lower than the average reduction in capacity in the early days of June and half of the reduction of the peak day of 6 MW.
EVN said that the power cuts in the North gradually decreased from June 6-15 compared to the beginning of the month, thanks to improved hydrological conditions and widespread rain in the northern river basins. The weather is cool, so the demand for electricity decreases, the average saving capacity in the North last week was about 6 MW, equivalent to the power output not meeting the demand of nearly 1.825%.
With the temperature in the North having cooled down, in 3 days (from June 13 to 15), the Hanoi area did not have to cut off electricity. In the remaining areas of the North, the power cut has gradually decreased and by June 6, the average saving capacity was reduced to only 15MW, accounting for about 6% of the used capacity.
But the demand for electricity increased again from 16-17/6. Updated data of EVN and the National Load Dispatch Center (A0) shows that the country's demand on June 16 is more than 6 million kWh, of which nearly half is in the North. The share of electricity in the Central region is 861% (8 million kWh) and 69,2% in the South, approximately 44 million kWh.
Data from the Electricity Regulatory Authority (Ministry of Industry and Trade) said that on June 16, all large lakes were above dead water but not many. If the maximum power generation operation is only maintained for 6-2 days. Currently, the lakes are storing more water to ensure power generation for the upcoming hot days.
However, incidents at coal-fired power plants are still at a high level with factories experiencing long-term problems with a total capacity of 2.100MW; The plant has a short-term problem of 660MW.
EVN said that in the coming days, it will continue to closely monitor the hydrological developments of hydroelectric power plants, making adjustments as soon as there are changes to "ensure the minimum amount of capacity cut".
Regarding the supply of coal, EVN said that fuel for coal-fired power plants across the country has been guaranteed.
Coal inventories at factories are mostly above one week of operation. Some factories have inventory equivalent to the number of operating days up to a whole month such as Pha Lai 2, Nghi Son 1, Vung Ang. Some factories have inventory with operating days equivalent to two months or more, such as Fomosa Ha Tinh, Nghi Son 2, Pha Lai 1, etc.
