On December 7, Tri An Hydropower Company announced the first overflow discharge to regulate the reservoir (phase 3).
Accordingly, at 8:00 a.m. on December 7, at Tri An hydropower reservoir, the upstream water level of the reservoir was 61.6 m, the water flow to the reservoir was 1,040 m3/s, the water flow through the spillway was 0 m3/s, the water flow through the power turbine was 179 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 downstream water level at Bien Hoa hydrological station will gradually decrease from tomorrow (December 8; to ensure the safety of the project and downstream, Tri An Hydropower Company will discharge water through the spillway to regulate the reservoir from 2:00 p.m. on December 8. The water flow through the spillway is 160m3/s and the water flow through the power turbine is from 340 m3/s to 600 m3/s (with a capacity of 180MW to 300MW depending on the mobilization method of the National Weather).
The total water flow discharged downstream is from 500 m3/s to 760 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.
The Company's Steering Committee for Natural Disaster Prevention and Search and Rescue informs the Civil Defense Committees at all levels and relevant local authorities to direct, coordinate and notify people in the downstream area of the reservoir to proactively take preventive measures to avoid possible impacts.
Previously, on December 2, Tri An Hydropower Company stopped releasing water through the spillway and hundreds of people went down to the foot of the spillway to catch fish.
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.
