There is little water in the hydropower reservoir, EVN forecasts that next week will still reduce electricity

EVN has just sent an update on the situation of electricity supply 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 reduce the temperature and maintain the level of 32-33 degrees Celsius from June 13 to June 06, but from June 17 to 06. 18 with heat increasing at 23-6 degrees Celsius, after June 36, the temperature drops to 37-24 degrees Celsius. In the coming time, the water in hydroelectric reservoirs has not been improved much, there is no information. flood news on the northern lakes.

EVN expects that in the coming week from June 17 to 24, the unsatisfactory capacity in the North will be about 6-2000 MW and depends heavily on the heat level as well as the water situation in hydropower reservoirs. Therefore, it is still necessary to reduce the demand for electricity until there is water in the hydropower reservoirs.

Regarding the electricity supply situation from June 1-15, EVN said that the fuel supply for coal-fired power plants across the country has been ensured. Southern oil plants have stopped needing to be mobilized. Meanwhile, hydrological developments in the first days of June continued to be poor.

EVN has maximized mobilization of thermal power sources in the North, increasing the maximum transmission limit from Central and South to North (2500-2700 MW), but the total capacity of the power source still cannot meet the demand for electricity use. used in the North. Faced with that situation, in order to ensure the safe operation of the power system, EVN has allocated available capacity to the Power Corporations, the Power Corporations allocated to the provincial power companies in compliance with the regulations. comply with the provisions of Circular 34/2011/TT-BCT dated September 7, 9. With the available capacity for the days from June 2011 to June 1 is 6 MW and from June 9 to now, it has increased to 6 MW.

In the days from June 9 to 13, hydrological conditions improved due to extensive rain on the northern river basins, so now the lake water level has been higher than the dead water level.

At the same time, the temperature in the North has also cooled down, so in the days of June 13-15, the Hanoi area did not have to reduce electricity. For the rest of the North, the reduction has gradually decreased and by June 6, the average saving capacity was reduced to only 15 MW, accounting for about 6% of the used capacity.

The latest information in the report of the Department of Safety Techniques and Industrial Environment (ATMT Department) just sent to the Minister of Industry and Trade on the operation of hydroelectric reservoirs said that, in addition to 4 hydroelectric reservoirs, approximately dead water mentioned above, there are a number of low-water lakes: Son La, Hua Na; a number of hydroelectric power plants 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 ATMT Department's report also said that on June 17, the flow of hydropower reservoirs was low. The South Central Coast region increased slightly compared to yesterday. The water level of hydropower reservoirs in the North and North Central region also increased slightly; In the Southeast region, the water level fluctuates slightly, still at low water level; In the South Central Coast region, in the Central Highlands, the water level of the lakes has decreased slightly, within the minimum water level prescribed by the operating procedures.

The amount of water returned to the lake is mainly to regulate the water to ensure the minimum flow, hydroelectric power plants operate and generate electricity with the return water flow, factories in the North and North Central region generate electricity with a moderate flow rate. , water level, low capacity to ensure safety for the unit when operating, it is difficult to meet the power generation according to the reservoir operation process at this period and forecast low water volume in the reservoirs in the future. next time.
