Water level of hydroelectric reservoir increases but remains very low, 9 power plants operate at a moderate level

Accordingly, nationwide, the water flow into the reservoirs increased compared to yesterday but is still low. Reservoirs in the Northern, North Central and Southeast regions exceeded the dead water level, but are still close to the dead water level; In the South Central Coast and Central Highlands, the water level of the reservoirs is at the minimum water level according to the regulations of the Operation Procedure. The water flow into the reservoirs is mainly to regulate the water to ensure the minimum flow.

This situation causes hydropower plants to operate and generate electricity based on the water flow, the number of plants near the dead water level concentrated in the Northern and North Central regions are generating electricity at a moderate level with low water column and capacity to ensure the safety of the generators during operation. Therefore, it is difficult to meet the electricity generation requirements according to the reservoir operation process at this time.

Some lakes are near dead water level: Son La, Thac Ba (Yen Bai), Tuyen Quang, Ban Chat (Lai Chau), Ban Ve (Nghe An), Hua Na (Nghe An), Trung Son (Hoa Binh), Thac Mo ( Binh Phuoc ).

Currently, 9 hydropower plants must generate electricity at low capacity and water column, including: Son La, Lai Chau , Huoi Quang, Ban Chat, Thac Ba, Tuyen Quang, Hua Na, Trung Son, Thac Mo.

Water level of hydroelectric reservoir increases but remains very low, 9 power plants operate at a moderate level - 1 — For more than a month now, the water level at Son La hydroelectric reservoir (section through Muong Lay town, Dien Bien ) has dropped below the dead water level, forcing the hydroelectric plant to stop operating.

Hydrological forecast, water flow to lakes in the next 24 hours fluctuates slightly; lake water level increases slightly, lakes in the Northern, Central Highlands, and Southeast regions are at low levels.

At the "hot spot" in the North, the flow of hydroelectric reservoirs is low, increasing compared to yesterday: Lai Chau Lake: 299 m3/s; Son La Lake: 513 m3/s; Hoa Binh Lake: 225 m3/s; Thac Ba Lake: 1625 m3/s; Tuyen Quang Lake: 110 m3/s; Ban Chat Lake: 60 m3/s.

Except for Hoa Binh Lake, the water level of the lakes is at dead level, slightly increased compared to yesterday. Specifically:

- Lai Chau Lake: 269.1 m/265 m (lake water level/dead water level)

- Son La Lake: 175.96/175 m

- Hoa Binh Lake: 103.60/80m (minimum water level: 81.9 m)

- Thac Ba Lake: 46.35/46 m (minimum regulation: 46.5 m)

- Tuyen Quang Lake: 91.44/90m (minimum regulation: 90.7m)

- Ban Chat Lake: 432.39m/431m.

- Trung Son Lake: 151.85/150 m (minimum requirement: 150.7m)

- Drawing Lake: 156.57/155.0 m (minimum requirement: 173.0 to 176.5m)

- Hua Na Lake: 216.12/215 m (minimum requirement: 220.7 m)

- Binh Dien Lake: 66.96/53 m (minimum requirement: 66.8 to 68.9m)

- Huong Dien Lake: 50.41/46 m (minimum regulation: 49.1 to 50.4m)

Meanwhile, in other areas, although the situation is less tense, many lakes still have water levels close to dead water level.

The inability to mobilize maximum power from hydropower plants has affected the management and operation of the power system and the supply of electricity for people's daily life, as well as causing many difficulties for business production.

Faced with a situation that could potentially affect the safety of the power system, leaders of the Ministry of Industry and Trade said that in recent days, EVN has had to regulate and reduce load in the North.
