Northern hydroelectric reservoirs escape 'dead water level'

As of 5:00 p.m. on June 16, the water level of Tuyen Quang hydroelectric reservoir reached 94.44 m (dead water level 90 m); Son La reservoir reached 177.98 m (dead water level 175 m); Huoi Quang reservoir reached 369.6 m (dead water level 368 m); Hoa Binh reservoir reached 102.75 m (dead water level 80 m); Ban Chat reservoir reached 436.08 m (dead water level 431 m); Lai Chau reservoir reached 276.77 m (dead water level 265 m).

The water flow at the lake is also more positive than the previous days. Specifically, at Tuyen Quang Lake it reached 268.33 m3/s; Son La Lake reached 352 m3/s; Huoi Quang Lake reached 87.7 m3/s; Hoa Binh Lake reached 520 m3/s, Ban Chat Lake reached 218.7 m3/s; Lai Chau Lake reached 277 m3/s.

Northern hydroelectric reservoirs escape 'dead water level' - 1 — The amount of water flowing into hydroelectric reservoirs has increased day by day.

Assessing the power supply situation on June 15, the Electricity Regulatory Authority said that the water flow to large hydroelectric reservoirs in the North has improved somewhat, the reservoirs are above the dead water level, however, the mobilization of large multi-purpose hydroelectric plants (except Hoa Binh Hydroelectric Plant) is limited to prepare for the upcoming hot days.

Coal-fired thermal power plants have had to run continuously at maximum capacity for a long time, so many technical problems have gradually appeared, causing a decrease in generator capacity and short-term problems.

Peak capacity in the North on June 15, 2023 reached 17,893 MW, of which peak capacity of Hydropower was 3,590 MW.

Northern hydroelectric reservoirs escape 'dead water level' - 2 — The water level at Hoa Binh hydroelectric reservoir is rising every day.

Implementing the Prime Minister's direction, the Ministry of Industry and Trade has implemented many specific groups of solutions to ensure electricity supply. These include implementing the Prime Minister's directive on electricity saving; ensuring coal and gas supply for power generation; actively adding new power sources to the system; focusing on overcoming power source problems...

However, the Ministry of Industry and Trade also recommends that although the water flow to the hydropower reservoirs in the North has improved somewhat, the reservoirs are above the dead water level. However, it is necessary to limit the mobilization of large multi-purpose hydropower plants (except Hoa Binh Hydropower Plant) to prepare for the upcoming hot days.
