Regarding the electricity supply situation on June 13, the Ministry of Industry and Trade said: Water flow at hydroelectric reservoirs has improved somewhat.
The total water flow to large hydroelectric reservoirs in the North increased by 28% compared to the water flow on June 11, mainly to Hoa Binh and Lai Chau reservoirs.
Recently, due to the limited mobilization of large multi-purpose hydropower plants (except Hoa Binh Hydropower Plant) to prepare for the upcoming hot days, the water levels of multi-purpose hydropower reservoirs have all been above the dead water level, but not much. If calculated, the total unmobilized capacity is about 5,000 MW.
"The water level of Lai Chau hydropower reservoir increased by 1.2m compared to June 11, Hoa Binh reservoir is still 22.8m from the dead water level," said the Ministry of Industry and Trade.
However, answering the press on June 13, Mr. Pham Van Vuong, Director of Hoa Binh Hydropower Company, said that the amount of water flowing into Hoa Binh Hydropower Reservoir is very low. Specifically, the amount of water flowing into Hoa Binh Hydropower Reservoir is only about 40m3/s.
If exploited to the maximum, after about 3 days there will not be enough pressure to generate maximum capacity, affecting the capacity reserve and after about 12-13 days the lake water will return to the dead water level.
Up to now, the total largest source capacity in the North has reached 18,580 MW, of which the largest capacity of hydropower is 3,800 MW.
However, according to the Ministry of Industry and Trade, many coal-fired thermal power plants still have problems with a total of 2,100MW of long-term problems and 580MW of short-term problems.
On June 12, 5 coal-fired thermal power plants in the Northern region had reduced capacity (Hai Phong, Quang Ninh, Mong Duong 1, Cam Pha, Thai Binh 2, Son Dong).
