On November 17, Tri An Hydropower Company announced a reduction in the amount of water released through the spillway to regulate the reservoir.
According to Tri An Hydropower Company, at 8:00 a.m. on November 16, the upstream water level of Tri An Lake was 61.596m, the water flow to the lake was 900m3/s, the water flow through the spillway was 480m3/s, the water flow through the power turbine was 564m3/s.
Based on the water flow to Tri An Lake, upstream water levels and hydrological information, Tri An Hydropower Company reduces the amount of overflow water released to regulate the reservoir.
Accordingly, from 8:00 a.m. on November 17, the water flow through the spillway will be reduced to 320m3/s. The water flow through the turbine generates electricity from 340 m3/s to 600 m3/s ( ranging from 180MW to 300MW, depending on the mobilization method of the National Regulations); The H1 plant stops major repairs as planned from November 15 to November 29.
The total water flow discharged downstream is from 600 m3/s to 920 m3/s (depending on the mobilization method of the National Regulations).
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 the water flow through the spillway.
Previously, from October 20, Tri An Hydropower Company released the first spillway to regulate the second phase of Tri An hydropower reservoir and continuously increased the discharge flow to 960m3/s (November 11) and then reduced the discharge flow.
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.
