Water flow to hydroelectric reservoirs continues to increase slightly

(HNMO) - A quick report on the morning of June 14 from the Department of Industrial Safety Techniques and Environment, Ministry of Industry and Trade, showed that the amount of water flowing into lakes in the North has increased slightly and will continue to increase in the next 24 hours.

On June 13, many areas in the northern mountainous region had rain, although the water flow was low, it helped improve the water level for hydroelectric reservoirs. Notably, the flow in some small river basins and streams in the northern region of Lai Chau, Lao Cai, and Ha Giang provinces increased rapidly.

The water flow at the lakes is recorded as follows: Lai Chau Lake: 401m3/s, Son La Lake: 278m3/s, Hoa Binh Lake: 404m3/s, Thac Ba Lake: 96m3/s, Tuyen Quang Lake: 425m3/s, Ban Chat Lake: 266m3/s.

The water has helped Lai Chau, Son La, Tuyen Quang, and Ban Chat lakes rise above the dead water level. Currently, only Thac Ba lake is close to the dead water level (45.91/46m).

According to the Department of Industrial Safety and Environment, the amount of water flowing into the reservoir is mainly to regulate the water flow to ensure minimum flow, hydroelectric plants operate to generate electricity based on the water flow. Plants in the Northern and North Central regions generate electricity at a moderate level with low water column and capacity to ensure safety for the generators during operation, it is difficult to meet the electricity generation according to the reservoir operation process at this time.

According to information from Hoa Binh Hydropower Plant, although it has rained in recent days, the amount of water flowing in is not much so the power generation capacity is still low.

It is forecasted that the hydrological situation and water flow to the lake will continue to increase slightly in the next 24 hours. According to the Electricity Regulatory Authority, the improved hydrological situation, along with the recovery of thermal power plants, will hopefully help reduce the tension in supplying electricity to the North in the coming days.
