Dead water level escapes, many hydropower plants in the North still stop generating electricity

According to the report of the Ministry of Industry and Trade on June 18, the water flow to hydroelectric reservoirs is equivalent to yesterday, including Lai Chau reservoir: 255 m3/s; Son La reservoir: 507 m3/s; Hoa Binh reservoir: 406 m3/s; Thac Ba reservoir: 76 m3/s; Tuyen Quang reservoir: 253 m3/s; Ban Chat reservoir: 280 m3/s.

The water level of the lakes has exceeded the dead water level, slightly increased compared to yesterday, but the hydroelectric reservoirs of Lai Chau, Son La, Thac Ba, Tuyen Quang, Ban Chat… still stop generating electricity to store water.

Responding to VTC News, Mr. Tran Viet Hoa, Director of the Electricity Regulatory Authority, said that the current hot weather combined with low lake water levels have led to many difficulties in supplying electricity to the national power system.

“The water in the hydroelectric reservoirs has only risen a few meters above the dead water level. If electricity is generated, it will return to the dead water level in just one or two days, causing difficulties for the plant, and at the same time consuming more water volume to generate 1kWh of electricity, while also affecting the technical performance of the generators,” said Mr. Hoa.

The report of the Department of Industrial Safety and Environment (DOST) of the Ministry of Industry and Trade on the operation of hydroelectric reservoirs shows that on June 18, the water flow to hydroelectric reservoirs was low, so the water level in these reservoirs has not improved much. The forecast of water flow to the reservoirs in the coming time is not high.

Hydropower plants in the Northern and North Central regions mainly regulate water to ensure minimum flow, and generate electricity moderately to ensure the safety of generators during operation, making it difficult to meet electricity generation requirements according to reservoir operation procedures at this time.

The water levels of lakes in the South Central Coast and Central Highlands are within the minimum water levels as prescribed in the Operational Procedures. Some lakes are close to dead water levels: Thac Ba, Ban Ve, Thac Mo, Dong Nai 3; Some lakes have low water levels: Son La, Hua Na.

According to the National Center for Hydro-Meteorological Forecasting, from June 18 to 19, the North will continue to experience severe heat with temperatures of 35 - 38 degrees Celsius, some places over 38 degrees Celsius. The area from Thanh Hoa to Phu Yen will experience particularly severe heat with temperatures of 36-38 degrees Celsius, some places over 39 degrees Celsius.

According to the forecast of the National Center for Hydro-Meteorological Forecasting, experts and the Ministry of Industry and Trade warn that the hot weather will continue and the demand for electricity will increase. Therefore, people and businesses need to raise their sense of responsibility and promote electricity saving programs to avoid pressure on the national power system, especially in the North.
