According to data from Vietnam Electricity Group, at 8:00 am on May 18, in the Northwest region, hydropower reservoirs on the Da River system continued to operate with large power generation.
Son La Lake reached a water level of 202.72 m, inflow to the lake 121 m3/s, total discharge and power generation output 1,878 m3/s. Hoa Binh Lake is at 104.84 m, inflow to 541 m3/s and power generation output 2,065 m3/s - the largest discharge level in the country at the present time.
Lai Chau, Ban Chat, and Huoi Quang reservoirs are still mainly stockpiled with water and have not generated electricity. Thac Ba Lake generates 146.52 m3/s of electricity, contributing to supplementing electricity for the Northern system.
In the Northeast region, Tuyen Quang reservoir recorded a water level of 109.21 m, 120 m lower than the normal water level; total discharge through power generation reached 405.91 m3/s.
The North Central region continues to record low water flow to the reservoirs. Trung Son and Ban Ve reservoirs have not been discharged for power generation. Khe Bo reservoir generates 95.5 m3/s of electricity, while Quang Tri reservoir generates electricity at a low level, only 9 m3/s.
Most hydropower reservoirs in the South Central region have not generated electricity or operate at a low level. Vinh Son A reservoir generates electricity at 6.81 m3/s; Song Tranh 2 generates electricity at 86 m3/s; Song Hinh generates electricity at 19.03 m3/s.
A Vuong, Song Bung 2, Song Bung 4, Vinh Son B, Vinh Son C and Song Ba Ha reservoirs have almost not been discharged.
The Central Highlands region recorded some reservoirs with significant power generation flow.
Se San 3A Lake generates 528 m3/s of electricity, Se San 4 reaches 510 m3/s, Buon Kuop discharges a total of 133.71 m3/s (of which overflow discharge is 15.71 m3/s), Buon Tua Srah generates 69 m3/s of electricity.
Ialy, Don Duong, and Dai Ninh reservoirs also generate electricity but at a lower level.
Tri An Lake has a water level of 57.14 m, water inflow to the lake is 200 m3/s but has not been discharged for electricity generation.
