On December 8, Tri An Hydropower Company announced an increase in the amount of water released through the spillway to regulate the reservoir.
Accordingly, at 3:00 p.m. on December 8, the upstream water level of Tri An hydropower reservoir was over 61.8 m; The downstream water level at the plant was 2.6 m; The water flow to the reservoir was 840 m3/s; The water flow through the spillway was 160 m3/s; The water flow through the power turbine was 544 m3/s.
Based on the water flow to Tri An Lake, the upstream water level, the discharge information of the above-level hydropower plants and the water level downstream at Bien Hoa hydrological station have passed the peak tide and are gradually decreasing, to ensure the safety of the project and downstream, the Company has increased the amount of water released to regulate the reservoir from 8:00 a.m. on December 9 with the water flow through the spillway being 320 m3/s and the water flow through the turbine generating electricity from 340 m3/s to 600 m3/s (equal to a capacity of 180MW to 300MW depending on the mobilization method of the National Weather Regulations - NSMO).
The total water flow downstream is from 660 m3/s to 920 m3/s.
Depending on weather developments, water flow to the lake, water level of Tri An Hydropower Reservoir, water level downstream at Bien Hoa hydrological station, the Company can flexibly regulate water flow through the spillway.
Previously, at 2:00 p.m. on December 8, Tri An Hydropower Company began releasing floodwaters in the third phase downstream with a total flow of 500 m3/s to 760 m3/s.
Tri An Hydropower Plant has 4 generators, with a total designed capacity of 400MW. This is the largest hydropower project in the Southern region, contributing greatly to the national grid, helping to regulate domestic and production water sources, push salinity and regulate floods in downstream areas.
